PMP 450 Configuration and User Guide pmp-0050 (May 2012) I Safety and regulatory information This section describes important safety and regulatory guidelines that must be observed by personnel installing or operating PMP 450 equipment. Important safety information To prevent loss of life or physical injury, observe the safety guidelines in this section. Power lines Exercise extreme care when working near power lines. Working at heights Exercise extreme care when working at heights. Grounding and protective earth PMP 450 units must be properly grounded to protect against lightning. It is the user‘s responsibility to install the equipment in accordance with national regulations. In the USA, follow Section 810 of the National Electric Code, ANSI/NFPA No.70-1984 (USA). In Canada, follow Section 54 of the Canadian Electrical Code. These codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire and discharge unit, size of grounding conductors and connection requirements for grounding electrodes. Other regulations may apply in different countries and therefore it is recommended that installation of the outdoor unit be contracted to a professional installer. Powering down before servicing Always power down and unplug the equipment before servicing. Primary disconnect device The main power supply is the primary disconnect device. External cables Safety may be compromised if outdoor rated cables are not used for connections that will be exposed to the outdoor environment.
Safety and regulatory information II pmp-0050 (May 2012) RF exposure near the antenna Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the power to the PMP 450 unit before undertaking maintenance activities in front of the antenna. Minimum separation distances Install the units so as to provide and maintain the minimum separation distances from all persons. Important regulatory information The PMP 450 product is certified as an unlicensed device in frequency bands where it is not allowed to cause interference to licensed services (called primary users of the bands). Radar avoidance In countries where radar systems are the primary band users, the regulators have mandated special requirements to protect these systems from interference caused by unlicensed devices. Unlicensed devices must detect and avoid co-channel operation with radar systems. The PMP 450 system provides detect and avoid functionality for countries and frequency bands requiring protection for radar systems. Installers and users must meet all local regulatory requirements for radar detection. To meet these requirements, users must set the correct region code during commissioning of the the PMP 450. If this is not done, installers and users may be liable to civil and criminal penalties. Contact the Cambium helpdesk if more guidance is required.
PMP 450 Configuration and User Guide pmp-0050 (May 2012) III USA and Canada specific information The USA Federal Communications Commission (FCC) has asked manufacturers to implement special features to prevent interference to weather radar systems that operate in the band 5600 MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in the band 5470 MHz to 5725 MHz. Manufacturers must ensure that such radio products cannot be configured to operate outside of FCC rules; specifically it must not be possible to disable or modify the radar protection functions that have been demonstrated to the FCC. In order to comply with these FCC requirements, Cambium supplies variants of the PMP 450 for operation in the USA or Canada. These variants are only allowed to operate with region codes that comply with FCC/IC rules. Other variants of the PMP 450 are available for use in the rest of the world, but these variants are not supplied to the USA or Canada except under strict controls, when they are needed for export and deployment outside the USA or Canada.

Preparing for configuration and alignment Chapter 2: Configuration and alignment 2-2 pmp-0050 (May 2012) Preparing for configuration and alignment This section describes the checks to be performed before proceeding with unit configuration and antenna alignment. Safety precautions during configuration and alignment All national and local safety standards must be followed while configuring the units and aligning the antennas. Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to radiate as soon as they are powered up. Observe the following guidelines: Never work in front of the antenna when the AP or SM is powered. Always power down the AP or SM before connecting or disconnecting the drop cable from the unit. Regulatory compliance during configuration and alignment All applicable radio regulations must be followed while configuring the units and aligning the antennas. USA only: if the system designer has provided a list of channels to be barred for TDWR radar avoidance, the affected channels must be barred during staging, before the units are allowed to radiate on site, otherwise FCC rules will be infringed.

Table 1 IP interface attributes Attribute Meaning IP Address Internet protocol (IP) address. This address is used by the family of Internet protocols to uniquely identify this unit on a network. Subnet Mask Defines the address range of the connected IP network. Gateway IP Address The IP address of a computer on the current network that acts as a gateway. A gateway acts as an entrance and exit to packets from and to other networks. DHCP state If Enabled is selected, the DHCP server automatically assigns the IP configuration (IP address, subnet mask, and gateway IP address) and the values of those individual parameters (above) are not used. The setting of this DHCP state parameter is also viewable, but not settable, in the Network Interface tab of the Home page. DNS IP Address Canopy devices allow for configuration of a preferred and alternate DNS server IP address either automatically or manually. Devices must set DNS server IP address manually when DHCP is disabled for the management interface of the device. DNS servers may be configured automatically from the DHCP response when DHCP is enabled for the management interface of the device. Optionally devices may be configured to set the DNS server IP address manually when DHCP is enabled for the management interface. The default DNS IP addresses are 0.0.0.0 when configured manually. Preferred DNS Server The first address used for DNS resolution.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-9 Attribute Meaning Alternate DNS Server Upon failure to reach the Preferred DNS server, the Alternate DNS Server is used. Domain Name The operator‘s management domain name may be configured for DNS. The domain name configuration can be used for configuration of the servers in the operator‘s network. The default domain name is example.com, and is only used if configured as such. LAN2 Network Interface Configuration (Radio Private Interface) – IP Address It is recommended to not change this parameter from the default AP private IP address of 192.168.101.1. A /24 CIDR subnet is used to communicate with each of the SMs that are registered. The AP uses a combination of the private IP and the LUID (logical unit ID) of the SM. For example, if an SM is the first to register in an AP, and another SM registers later, then the AP whose Private IP address is 192.168.101.1 uses the following SM Private IP addresses to communicate to each: SM LUID Private IP First SM registered 2 192.168.101.2 Second SM registered 3 192.168.101.3

Table 4 SM with NAT disabled - IP attributes Attribute Meaning LAN1 Network Interface Configuration, IP Address Enter the non-routable IP address to associate with the Ethernet connection on this SM. (The default IP address from the factory is 169.254.1.1.) If you set and then forget this parameter, then you must both physically access the module. use an override plug to electronically access the module configuration parameters at 169.254.1.1. See Overriding Forgotten IP Addresses or Passwords on AP on Page 2-60. Note or print the IP settings from this page. Ensure that you can readily associate these IP settings both with the module and with the other data that you store about the module. LAN1 Network Interface Configuration, Network Accessibility Specify whether the IP address of the SM should be visible to only a device connected to the SM by Ethernet (Local) or should be visible to the AP as well (Public). LAN1 Network Interface Configuration, Subnet Mask Enter an appropriate subnet mask for the SM to communicate on the network. The default subnet mask is 255.255.0.0. LAN1 Network Interface Configuration, Gateway IP Address Enter the appropriate gateway for the SM to communicate with the network. The default gateway is 169.254.0.0.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-15 Attribute Meaning LAN1 Network Interface Configuration, DHCP state If you select Enabled, the DHCP server automatically assigns the IP configuration (IP address, subnet mask, and gateway IP address) and the values of those individual parameters (above) are not used. The setting of this DHCP state parameter is also viewable, but not settable, in the Network Interface tab of the Home page. In this tab, DHCP State is settable only if the Network Accessibility parameter in the IP tab is set to Public. This parameter is also settable in the NAT tab of the Configuration web page, but only when NAT is enabled. If the DHCP state parameter is set to Enabled in the Configuration => IP tab of the SM, do not check the BootpClient option for Packet Filter Types in its Protocol Filtering tab, because doing so would block the DHCP request. (Filters apply to all packets that leave the SM via its RF interface, including those that the SM itself generates.) If you want to keep DHCP enabled and avoid the blocking scenario, select the Bootp Server option instead. This will result in responses being appropriately filtered and discarded. LAN1 Network Interface Configuration, DNS IP Address Canopy devices allow for configuration of a preferred and alternate DNS server IP address either automatically or manually. Devices must set DNS server IP address manually when DHCP is disabled for the management interface of the device. DNS servers may be configured automatically from the DHCP response when DHCP is enabled for the management interface of the device. Optionally devices may be configured to set the DNS server IP address manually when DHCP is enabled for the management interface. The default DNS IP addresses are 0.0.0.0 when configured manually. LAN1 Network Interface Configuration, Preferred DNS Server The first DNS server used for DNS resolution. LAN1 Network Interface Configuration, Alternate DNS Server The second DNS server used for DNS resolution. LAN1 Network Interface Configuration, Domain Name The operator‘s management domain name may be configured for DNS. The domain name configuration can be used for configuration of the servers in the operator‘s network. The default domain name is example.com, and is only used if configured as such.

With NAT enabled, the SM has an IP address for transport traffic separate from its address for management, terminates transport traffic, and allows you to assign a range of IP addresses to devices that are connected to the Ethernet/wired side of the SM. When NAT is enabled, VLANs are not supported on the wired side of that SM. You can enable NAT in SMs within a sector where VLAN is enabled in the AP, but this may constrain network design. WAN Interface The WAN interface is the RF-side address for transport traffic.
Task 2: Configuring IP and Ethernet interfaces Chapter 2: Configuration and alignment 2-18 pmp-0050 (May 2012) Attribute Meaning WAN Interface, Connection Type This parameter may be set to Static IP—when this is the selection, the following three parameters (IP Address, Subnet Mask, and Gateway IP Address) must all be properly populated. DHCP—when this is the selection, the information from the DHCP server configures the interface. PPPoE—when this is the selection, the information from the PPPoE server configures the interface. WAN Interface, Subnet Mask If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the subnet mask of the SM for RF transport traffic. WAN Interface, Gateway IP Address If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the gateway IP address for the SM for RF transport traffic. WAN Interface, Reply to Ping on WAN Interface By default, the radio interface does not respond to pings. If you use a management system (such as Prizm or WM) that will occasionally ping the SM, set this parameter to Enabled. LAN Interface The LAN interface is both the management access through the Ethernet port and the Ethernet-side address for transport traffic. When NAT is enabled, this interface is redundantly shown as the NAT Network Interface Configuration on the IP tab of the Configuration web page in the SM. LAN Interface, IP Address Assign an IP address for SM management through Ethernet access to the SM. This address becomes the base for the range of DHCP-assigned addresses. LAN Interface, Subnet Mask Assign a subnet mask of 255.255.255.0 or a more restrictive subnet mask. Set only the last byte of this subnet mask. Each of the first three bytes is permanently set to 255. LAN Interface, DMZ Enable Either enable or disable DMZ for this SM. LAN Interface, DMZ IP Address If you enable DMZ in the parameter above, set the last byte of the DMZ host IP address to use for this SM when DMZ is enabled. Only one such address is allowed. The first three bytes are identical to those of the NAT private IP address. Ensure that the device that should receive network traffic behind this SM is assigned this address. The system provides a warning if you enter an address within the range that DHCP can assign. LAN DHCP Server This is the server (in the SM) that provides an IP address to the device connected to the Ethernet port of the SM. WAN Interface, Subnet Mask If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the subnet mask of the SM for RF transport traffic.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-19 Attribute Meaning LAN DHCP Server, DHCP Server Enable/Disable Select either Enabled to allow this SM to assign IP addresses, subnet masks, and gateway IP addresses to attached devices. assign a start address for DHCP. designate how many IP addresses may be temporarily used (leased). Disabled to disallow the SM to assign addresses to attached devices. LAN DHCP Server, DHCP Server Lease Timeout Based on network performance, enter the number of days between when the DHCP server assigns an IP address and when that address expires. The range of values for this parameter is 1 to 30 days. The default value is 30 days. LAN DHCP Server, DHCP Start IP If you will be enabling DHCP Server below, set the last byte of the starting IP address that the DHCP server will assign. The first three bytes are identical to those of the NAT private IP address. LAN DHCP Server, Number of IPs to Lease Enter how many IP addresses the DHCP server is allowed to assign. The default value is 50 addresses. LAN DHCP Server, DNS Server Proxy This parameter enables or disables advertisement of the SM as the DNS server. On initial boot up of an SM with the NAT WAN interface configured as DHCP or PPPoE, the SM module will not immediately have DNS information. With DNS Server Proxy disabled, the clients will renew their lease about every minute until the SM has the DNS information to give out. At this point the SM will go to the full configured lease time period which is 30 days by default. With DNS Server Proxy enabled, the SM will give out full term leases with its NAT LAN IP as the DNS server. LAN DHCP Server, DNS IP Address Select either Obtain Automatically to allow the system to set the IP address of the DNS server. Set Manually to enable yourself to set both a preferred and an alternate DNS IP address. LAN DHCP Server, Preferred DNS IP Address Enter the preferred DNS IP address to use when the DNS IP Address parameter is set to Set Manually. LAN DHCP Server, Alternate DNS IP Address Enter the DNS IP address to use when the DNS IP Address parameter is set to Set Manually and no response is received from the preferred DNS IP address. Remote Configuration Interface, Interface Enable/Disable If you want over-the-air management capability for the SM, select Enabled. If you want to limit management of the SM to its Ethernet interface, select Disabled.
Task 2: Configuring IP and Ethernet interfaces Chapter 2: Configuration and alignment 2-20 pmp-0050 (May 2012) Attribute Meaning Remote Configuration Interface The Remote Configuration interface is the RF-side address for management by an EMS or NMS (Prizm or WM, for example). Remote Configuration Interface, Interface Enable/Disable When this interface is Disabled, the SM is not directly accessible by IP address, and management access is only through either the LAN (Ethernet) interface a link from an AP web page into the WAN (RF-side) interface. When this interface is Enabled, you can configure management access through either a Static IP address an IP address that DHCP provides for the WAN interface. Remote Configuration Interface, Connection Type This parameter may be set to Static IP—when this is the selection, the following three parameters (IP Address, Subnet Mask, and Gateway IP Address) must all be properly populated. DHCP—when this is the selection, the information from the DHCP server configures the interface. Remote Configuration Interface, IP Address If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the IP address of the SM for RF management traffic. Remote Configuration Interface, Subnet Mask If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the subnet mask of the SM for RF management traffic. Remote Configuration Interface, Gateway IP Address If Static IP is set as the Connection Type of the WAN interface, then this parameter configures the gateway IP address for the SM for RF management traffic. Note or print the IP settings from this page. Ensure that you can readily associate these IP settings both with the module and with the other data that you store about the module. NAT Protocol Parameters, ARP Cache Timeout If a router upstream has an ARP cache of longer duration (as some use 30 minutes), enter a value of longer duration than the router ARP cache. The default value of this field is 20 minutes. NAT Protocol Parameters, TCP Session Garbage Timeout Where a large network exists behind the SM, you can set this parameter to lower than the default value of 1440 minutes (24 hours). This action makes additional resources available for greater traffic than the default value accommodates. The default value of this parameter is 120 minutes. NAT Protocol Parameters, UDP Session Garbage Timeout You may adjust this parameter in the range of 1 to 1440 minutes, based on network performance. The default value of this parameter is 4 minutes.

Table 8 SM with NAT enabled - IP attributes Attribute Meaning VLAN Specify whether VLAN functionality for the AP and all linked SMs should (Enabled) or should not (Disabled) be allowed. The default value is Disabled. Always use Local VLAN Config Enable this option before you reboot this AP as an SM to use it to perform spectrum analysis. After the spectrum analysis is completed and before you reboot this module as an AP, disable this option.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-23 Attribute Meaning Dynamic Learning Specify whether the AP should (Enabled) or should not (Disabled) add the VLAN IDs (VIDs) of upstream frames to the VID table. (The AP passes frames with VIDs that are stored in the table both upstream and downstream.) The default value is Enabled. Allow Frame Types Select the type of arriving frames that the AP should tag, using the VID that is stored in the Untagged Ingress VID parameter. The default value is All Frames. VLAN Aging Timeout Specify how long the AP should keep dynamically learned VIDs. The range of values is 5 to 1440 (minutes). The default value is 25 (minutes). VIDs that you enter for the Management VID and VLAN Membership parameters do not time out. Management VID Enter the VID that the operator wishes to use to communicate with the module manager. The range of values is 1 to 4095. The default value is 1. SM Management VID Pass-through Specify whether to allow the SM (Enable) or the AP (Disable) to control the VLAN settings of the SM. The default value is Enable. Do not set this parameter to Enable where both a BAM release earlier than 2.1 is implemented. The Configuration Source parameter in the AP is set to BAM. This combination causes the SMs to become unmanageable, until you gain direct access with an override plug and remove this combination from the AP configuration. QinQ EtherType This parameter is the outer S-VLAN Ethertype that may be configured to interoperate with other networks that use a different Ethertype than the default. Active Configuration When VLAN is enabled in the AP, the Active Configuration block provides the following details as read-only information in this tab. In the Motorola fixed wireless broadband IP network, each device of any type is automatically a permanent member of VID 1. This facilitates deployment of devices that have VLAN enabled with those that do not.
Task 2: Configuring IP and Ethernet interfaces Chapter 2: Configuration and alignment 2-24 pmp-0050 (May 2012) Attribute Meaning Port VID This is the VID that the AP will use for tagging frames of the type specified by Allow Frame Types. Management VID This is the value of the parameter of the same name, configured above. SM Management VID Pass-Through This is the value of the parameter of the same name, configured above. Dynamic Ageing Timeout This is the value of the VLAN Aging Timeout parameter configured above. Allow Learning Yes is displayed if the value of the Dynamic Learning parameter above is Enabled. No is displayed if the value of Dynamic Learning is Disabled. Allow Frame Type This displays the selection that was made from the drop-down list at the Allow Frame Types parameter above. Current VID Member Set, VID Number This column lists the ID numbers of the VLANs in which this module is a member, whether through assignment or through dynamic learning. Current VID Member Set, Type For each VID number in the first column, the entry in this column correlates the way in which the module became and continues to be a member: Permanent—This indicates that the module was assigned the VID number through direct configuration by the operator. Dynamic—This indicates that the module adopted the VID number through enabled dynamic learning, when a tagged packet from an SM behind it in the network, or from a customer equipment that is behind the SM in this case, was read.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-25 Attribute Meaning Current VID Member Set, Age For each VID number in the first column of the table, the entry in this column reflects whether or when the VID number will time out: for Permanent type—the number will never time out, and this is indicated by the digit 0. for Dynamic type—the Age reflects what is configured in the VLAN Aging Timeout parameter in the Configuration => VLAN tab of the AP or reflects a fewer number of minutes that represents the difference between what was configured and what has elapsed since the VID was learned. Each minute, the Age decreases by one until, at zero, the AP deletes the learned VID, but can it again from packets sent by elements that are beneath it in the network. Values in this Active Configuration block can differ from attempted values in configurations: A VLAN profile administered by the BAM subsystem in Prizm is capable of overriding any configured VLAN value, if the Configuration Source parameter in the AP is set to Authentication Server. The AP itself can override the value that the SM has configured for SM Management VID Pass-Through.

Table 12 SM VLAN attributes Attribute Meaning Always use Local VLAN Config Enable this option before you reboot this AP as an SM to use it to perform spectrum analysis. After the spectrum analysis is completed and before you reboot this module as an AP, disable this option.
Task 2: Configuring IP and Ethernet interfaces Chapter 2: Configuration and alignment 2-28 pmp-0050 (May 2012) Attribute Meaning VLAN Port Type By default this will be simply Q, indicating that it is to operate in the existing manner. The other option is Q-in-Q, which indicates that it should be adding and removing the S-Tag, and adding a C-Tag if necessary for untagged packets. The VLAN Port type corresponds to the Ethernet port of the SM. Currently, the internal management interfaces will always operate as Q ports. Accept QinQ Frames This option is valid for the Q-in-Q port so that the user may force blocking of existing 802.1ad Q-in-Q frames. This way, only untagged or single tagged packets will come in and out of the Ethernet interface. If a Q-in-Q frame is about ingress or egress the Ethernet interface and this is disabled, it will be dropped and a filter entry will show up on the VLAN Statistics page as DVLAN Egress or DVLAN Ingress. Dynamic Learning Specify whether the SM should (Enable) or should not (Disable) add the VIDs of upstream frames (that enter the SM through the wired Ethernet interface) to the VID table. The default value is Enable. Allow Frame Types Select the type of arriving frames that the SM should tag, using the VID that is stored in the Untagged Ingress VID parameter. The default value is All Frames. VLAN Aging Timeout Specify how long the SM should keep dynamically learned VIDs. The range of values is 5 to 1440 (minutes). The default value is 25 (minutes). VIDs that you enter for the Untagged Ingress VID and Management VID parameters do not time out. Management VID Enter the VID that the SM should share with the AP. The range of values is 1 to 4095. The default value is 1. SM Management VID Pass-through Specify whether to allow the SM (Enable) or the AP (Disable) to control the VLAN settings of this SM. The default value is Enable. When VLAN is enabled in the AP to whom this SM is registered, the Active Configuration block provides the following details as read-only information in this tab. In the Motorola fixed wireless broadband IP network, each device of any type is automatically a permanent member of VID 1. This facilitates deployment of devices that have VLAN enabled with those that do not.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-29 Attribute Meaning Default Port VID This is the VID that will be used for untagged frames and will correspond to the Q-Tag for 802.1Q frames (if VLAN Port Type is Q), or the C-Tag for 802.1ad frames (if the VLAN Port Type is Q-in- Q). Port VID MAC Address Mapping These parameters allow operators to place specific devices onto different VLANs (802.1Q tag or 802.1ad C-tag) based on the source MAC address of the packet. If the MAC address entry is 00-00-00-00-00-00 then that entry is not used. If a packet arrives at the SM that is sourced from a device whose MAC address is in the table, then the corresponding VID will be used for that frame‘s Q-tag (Q port) or C-tag (Q-in-Q port). If there is no match, then the Default Port VID will be used. This table is also used in the downstream direction for removal of the tag based on the destination MAC address so that an untagged (for Q port) or Q-Tagged (for Q-in-Q port) frame is delivered to the end device. You may use wildcards for the non-OUI (Organizationally Unique Identifier) portion of the MAC address, which is the last 3 bytes. MAC addresses contain 6 bytes, the first 3 of which are the OUI of the vendor that manufactured the device and the last 3 are unique to that vendor OUI. If you want to cover all devices from a known vendor‘s OUI, you would specify 0xFF for the remaining 3 bytes. So, for example, if you wanted all devices from a specific vendor with an OUI of 00-95-5b (which is a Netgear OUI) to be on the same VID of 800, you would specify an entry with MAC address 00-95-5b-ff-ff-ff. Then, any device underneath of the SM with MAC addresses starting with 00-95-5b will be put on VLAN 800. Provider VID The provider VID is used for the S-tag. It is only used if the Port Type is Q-in-Q and will always be used for the S-tag. If an existing 802.1Q frame arrives, the Provider VID is what will be used for adding and removing of the outer S-tag. If an untagged frame arrives to a Q-in-Q port, then the Provider VID will be the S-tag and the Default Port VID (or Port VID MAC Address Mapping, if valid) will be used for the C-tag. Active Configuration, Default Port VID This is the value of the parameter of the same name, configured above. Active Configuration, MAC Address VID Map This is the listing of the MAC address VIDs configured in Port VID MAC Address Mapping.

Similarly, for any VLAN in which you want the AP to no longer be a member, enter the VLAN ID and then click the Remove Member button. PPPoE Tab of the SM Table 14 PPPoE tab of the SM Point-to-Point Protocol over Ethernet (PPPoE) is a protocol that encapsulates PPP frames inside Ethernet frames (at Ethernet speeds). Benefits to the network operator may include Access control Service monitoring Generation of statistics about activities of the customer Re-use of infrastructure and operational practices by operators who already use PPP for other networks PPPoE options are configurable for the SM only, and the AP indicates whether or not PPPoE is enabled for a specific subscriber.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-33 When PPPoE is enabled, once the RF session comes up between the SM and the AP, the SM will immediately attempt to connect to the PPPoE Server. You can monitor the status of this by viewing the PPPoE Session Log in the Logs section (Administrator only). Every time the RF session comes up, the SM will check the status of the link and if it is down, the SM will attempt to redial the link if necessary depending on the Timer Type. Also, on the Configuration page, the user may Connect or Disconnect the session manually. This can be used to override the session to force a manual disconnect and/or reconnect if there is a problem with the session. In order to enable PPPoE, NAT MUST be enabled on the SM, and Translation Bridging MUST be disabled on the AP. These items will be strictly enforced for you when you are trying to enable PPPoE. A message will indicate any prerequisites not being met. Also, the NAT Public IP DHCP client cannot be enabled This is because the NAT Public IP will be received through the IPCP process of the PPPoE discovery stages. The pre-requisites required are: NAT MUST be enabled on the SM o NAT DHCP Client will be disabled automatically. The NAT public IP will be received from the PPPoE Server. o NAT Public Network Interface Configuration will not be used and should be left to defaults. Also NAT Public IP DHCP will be disabled if it is enabled. Translation Bridging MUST be DISABLED on the AP o This will only be determined if the SM is in session since the SM won‘t know the AP configuration otherwise. If the SM is not in session, PPPoE can be enabled but if the SM goes into session to a Translation Bridge-enabled AP, then PPPoE will not be enabled. The following PPPoE configuration parameters are available: Table 15 SM PPPoE attributes Attribute Meaning Access Concentrator An optional entry to set a specific access concentrator to connect to for the PPPoE session. If this is blank, the SM will accept the first access concentrator which matches the service name (if specified). This is limited to 32 characters. Service Name An optional entry to set a specific service name to connect to for the PPPoE session. If this is left blank the SM will accept the first service option that comes back from the access concentrator specified above, if any. This is limited to 32 characters. Authentication Type None means that no PPPoE authentication will be implemented CHAP/PAP means that CHAP authentication will be attempted first, then PAP authentication. The same password is used for both types. User Name This is the CHAP/PAP user name that will be used if CHAP/PAP authentication is selected. If None is selected for authentication then this field is unused. This is limited to 32 characters.
Task 2: Configuring IP and Ethernet interfaces Chapter 2: Configuration and alignment 2-34 pmp-0050 (May 2012) Attribute Meaning Password This is the CHAP/PAP password that will be used if PAP authentication is selected. If None is selected for authentication then this field is unused. This is limited to 32 characters. MTU Use MTU Received from PPPoE Server causes the SM to use the MRU of the PPPoE server received in LCP as the MTU for the PPPoE link. Use User Defined MTU allows the operator to specify an MTU value to use to override any MTU that may be determined in the LCP phase of PPPoE session setup. If this is selected, the user will be able to enter an MTU value up to 1492. However, if the MTU determined in LCP negotiations is less than this user-specified value, the SM will use the smaller value as its MTU for the PPPoE link. Timer Type Keep Alive is the default timer type. This timer will enable a keepalive that will check the status of the link periodically. The user can set a keepalive period. If no data is seen from the PPPoE server for that period, the link will be taken down and a reconnection attempt will be started. For marginal links, the keep alive timer can be useful so that the session will stay alive over periodic dropouts. The keepalive timer should be set such that the session can outlast any session drop. Some PPPoE servers will have a session check timer of their own so that the timeouts of the server and the SM should be in sync so that one side does not drop the session prematurely. Idle Timeout enables an idle timer that will check the usage of the link from the customer side. If there is no data seen from the customer for the idle timeout period, the PPPoE session will be dropped. Once data starts flowing from the customer again, the session will be started up again. This timer is useful for users who may not be using the connection frequently. If the session is idle for long periods of time, this timer will allow the resources used by the session to be returned to the server. Once the connection is used again by the customer, the link will be reestablished automatically.
PMP 450 Configuration and User Guide Task 2: Configuring IP and Ethernet interfaces pmp-0050 (May 2012) 2-35 Attribute Meaning TCP MSS Clamping If this is enabled, then the SM will alter TCP SYN and SYN-ACK packets by changing the Maximum Segment Size to be compatible with the current MTU of the PPPoE link. This way, the user does not have to worry about MTU on the client side for TCP packets. The MSS will be set to the current MTU – 40 (20 bytes for IP headers and 20 bytes for TCP headers). This will cause the application on the client side to not send any TCP packets larger than the MTU. If the network is exhibiting large packet loss, try enabling this option. This may not be an option on the PPPoE server itself. The SM will NOT reassemble IP fragments, so if the MTUs are incorrect on the end stations, then MSS clamping will solve the problem for TCP connections.

PMP 450 Configuration and User Guide Task 3: Upgrading the software version and using CNUT pmp-0050 (May 2012) 2-37 Task 3: Upgrading the software version and using CNUT This task consists of the following procedures: Checking the installed software version on page 2-37 Upgrading to a new software version on page 2-37 If the link is operational, ensure that the remote end of the link is upgraded first using the wireless connection, and then the local end can be upgraded. Otherwise, the remote end may not be accessible. Checking the installed software version To check the installed software version, proceed as follows: 1 Select Home menu tab General. 2 Note the installed Software Version (near the top of the page): 3 Go to the support website (see Contacting Cambium Networks on page 1-9) and find Point-to-Multipoint software updates. Check that the latest PMP 450 software version (for example 13.0) is the same as the installed Software Version. 4 If the software needs to be upgraded to the latest version, perform Upgrading to a new software version on page 2-37. Upgrading to a new software version PMP 450 modules are upgraded using the Canopy Network Updater Tool (CNUT). The Canopy Network Updater Tool (CNUT) manages and automates the software and firmware upgrade process for a Canopy radio, CMMmicro, or CMM4 (but not its 14-port switch) across the network. This eliminates the need for an administrator to visit each radio in the network (or each AP while using the Autoupdate feature) to upgrade the modules. This section includes an example of updating a single unit before deployment. System-wide upgrading procedures may be found in the CNUT Online Help manual, which can be found on the Cambium support website (see Contacting Cambium Networks on page 1-9).
Task 3: Upgrading the software version and using CNUT Chapter 2: Configuration and alignment 2-38 pmp-0050 (May 2012) CNUT functions The Canopy Network Updater Tool automatically discovers all network elements o executes a UDP command that initiates and terminates the Autoupdate mode within APs. This command is both secure and convenient: o For security, the AP accepts this command from only the IP address that you specify in the Configuration page of the AP. o For convenience, Network Updater automatically sets this Configuration parameter in the APs to the IP address of the Network Updater server when the server performs any of the update commands. allows you to choose among updating o your entire network. o only elements that you select. o only network branches that you select. provides a Script Engine that you can use with any script that o you define. o Motorola supplies. Network element groups With the Canopy Network Updater Tool, you can identify element groups composed of network elements that you select. Identifying these element groups organizes the display of elements (for example, by region or by AP cluster). allows you to o perform an operation on all elements in the group simultaneously. o set group-level defaults for telnet or ftp password access and SNMP Community String (defaults that can be overridden in an individual element when necessary). Network layers A typical network contains multiple layers of elements, with each layer farther from the Point of Presence. For example, SMs are behind an AP and thus, in this context, at a lower layer than the AP. Correctly portraying these layers in Network Updater is essential so that Network Updater can perform radio and AP cluster upgrades in an appropriate order. Correct layer information ensures that Network Updater does not command an AP that is behind another AP/SM pair (such as in a remote AP installation) to perform an upgrade at the same time as the SM that is feeding the AP. If this occurs, then the remote AP loses network connection during the upgrade (when the SM in front of the AP completes its upgrade and reboots). Script engine Script Engine is the capability in Network Updater that executes any user-defined script against any network element or element group. This capability is useful for network management, especially for scripts that you repetitively execute across your network.

PMP 450 Configuration and User Guide Task 4: Configuring General and Unit settings pmp-0050 (May 2012) 2-41 Task 4: Configuring General and Unit settings General Tab of the AP Table 18 General tab of the AP The General tab of the AP contains many of the configurable parameters that define how the AP and the SMs in the sector operate.
Task 4: Configuring General and Unit settings Chapter 2: Configuration and alignment 2-42 pmp-0050 (May 2012) Table 19 SM PPPoE attributes Attribute Meaning Device Setting You can temporarily transform an AP into an SM and thereby use the spectrum analyzer functionality. Otherwise, the selection for this parameter is AP. Link Speeds From the drop-down list of options, select the type of link speed for the Ethernet connection. The default for this parameter is that all speeds are selected: Auto 100F/100H/10F/10H. In this setting, the two ends of the link automatically negotiate with each other whether the speed that they will use is 10 Mbps or 100 Mbps and whether the Ethernet traffic will be full duplex or half duplex. However, Ethernet links work best when either both ends are set to the same forced selection both ends are set to auto-negotiate and both have capability in least one common speed and traffic type combination. Configuration Source See Setting the Configuration Source Sync Input Specify the type of synchronization for this AP to use: Select Sync to Received Signal (Power Port) to set this AP to receive sync from a connected CMMmicro or CMM4. Select Sync to Received Signal (Timing Port) to set this AP to receive sync from a connected CMM2, an AP in the cluster, or an SM. Select Generate Sync Signal where the AP does not receive sync, and no other AP is active within the link range.
PMP 450 Configuration and User Guide Task 4: Configuring General and Unit settings pmp-0050 (May 2012) 2-43 Attribute Meaning Region Code From the drop-down list, select the region in which the radio is operating. Selectable regions are: Australia Brazil Canada Europe India Indonesia Russia Spain Unites States Other When the appropriate region is selected in this parameter, the radio automatically implements the applicable required Dynamic Frequency Selection (DFS) standard. Unlike selections in other parameters, your Region Code selection requires a Save Changes and a Reboot cycle before it will force the context-sensitive GUI to display related options (for example, Alternate Frequency Carrier 1 and 2 in the Configuration => Radio tab). Thus, a proper configuration exercise in environments that are subject to DFS requirements has two imperative Save Changes and Reboot cycles: one after the Region Code is set, and a second after related options are set. Webpage Auto Update Enter the frequency (in seconds) for the web browser to automatically refresh the web-based interface. The default setting is 0. The 0 setting causes the web-based interface to never be automatically refreshed. Bridge Entry Timeout Specify the appropriate bridge timeout for correct network operation with the existing network infrastructure. The Bridge Entry Timeout should be a longer period than the ARP (Address Resolution Protocol) cache timeout of the router that feeds the network. An inappropriately low Bridge Entry Timeout setting may lead to temporary loss of communication with some end users. Translation Bridging If you want the Translation Bridging feature, select Enabled. This has numerous implications.
Task 4: Configuring General and Unit settings Chapter 2: Configuration and alignment 2-44 pmp-0050 (May 2012) Attribute Meaning Send Untranslated ARP If the Translation Bridging parameter is set to Enabled, then the Send Untranslated ARP parameter can be disabled, so that the AP will overwrite the MAC address in Address Resolution Protocol (ARP) packets before forwarding them. enabled, so that the AP will forward ARP packets regardless of whether it has overwritten the MAC address. If the Translation Bridging parameter is set to Disabled, then the Send Untranslated ARP parameter has no effect. SM Isolation Prevent or allow SM-to-SM communication by selecting from the following drop-down menu items: Disable SM Isolation (the default selection). This allows full communication between SMs. Block SM Packets from being forwarded. This prevents both multicast/broadcast and unicast SM-to-SM communication. Block and Forward SM Packets to Backbone. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise would have been handled SM to SM, through the Ethernet port of the AP. Update Application Address Enter the address of the server to access for software updates on this AP and registered SMs. 2X Rate This parameter is present in only PMP 100 Series APs. You should generally keep this parameter set to Enabled to allow the module to automatically the operation rate. For troubleshooting, you may lock the rate down (Disabled), but be aware that this locks down the operation rate for all uplinks and downlinks across the sector. Dynamic Rate Adapt This parameter is present in only PMP 400 Series APs. You should generally keep this parameter set to Enabled to allow the module to automatically the operation rate. For troubleshooting, you may lock the rate down (Disabled), but be aware that this locks down the operation rate for all uplinks and downlinks across the sector. Prioritize TCP ACK To reduce the likelihood of TCP acknowledgement packets being dropped, set this parameter to Enabled. This can improve throughput that the end user perceives during transient periods of congestion on the link that is carrying acknowledgements.
PMP 450 Configuration and User Guide Task 4: Configuring General and Unit settings pmp-0050 (May 2012) 2-45 Attribute Meaning Multicast Destination Address Using Link Layer Discovery Protocol (LLDP), a module exchanges multicast addresses with the device to which it is wired on the Ethernet interface. Although some switches (CMMmicro, for example) do not pass LLDP addresses upward in the network, a radio can pass it as the value of the Multicast Destination Address parameter value in the connected device that has it populated. In this way, an SM can report to Prizm, for example, the multicast address of a connected remote AP, and thus allow Prizm to discover that AP. To allow this, set the message mode in the remote AP to LLDP Multicast. The SM will pass this address in broadcast mode, and the CMMmicro will pass the address upward in the network, since it does not discard addresses that it receives in broadcast mode. Where the AP is not behind another device, the Broadcast mode will allow discovery of the AP. DHCP Relay Agent The AP may act as a DHCP relay for SMs and CPEs underneath it. The AP will make use of the DHCP Option 82 (DHCP Relay Agent Information) from RFC 3046 when performing relay functions. The AP offers two types of DHCP relay functionality: Full Relay Information. Configuring the DHCP Full Relay Operation will take broadcast DHCP packets and send them to a Unicast server in unicast mode. This way the DHCP requests and replies can be routed like any other UDP packet. Only Insert Option 82. This option leaves the DHCP request on its broadcast domain as opposed to DHCP Full Relay Operation which will turn it into a unicast packet. In order to accommodate setting up pools or classes for different VLANs, the Option 82 field will include information to tell the server what VLAN the client is on. DHCP Server (Name or IP Address) The DHCP relay server may be either a DNS name or a static IP address in dotted decimal notation. Additionally the management DNS domain name may be toggled such that the name of the DHCP relay server only needs to be specified and the DNS domain name is automatically appended to that name. The default DHCP relay server addresses is 255.255.255.255 with the appending of the DNS domain name disabled. Coordinates Physical radio location data may be configured via the Latitude, Longitude, and Height fields.
Task 4: Configuring General and Unit settings Chapter 2: Configuration and alignment 2-46 pmp-0050 (May 2012) Unit Settings Tab of the AP Table 20 Unit Settings tab of the AP The Unit Settings tab of the AP contains an option for how the AP should react when it detects a connected override plug. You may set this option as follows. Table 21 AP Unit Settings attributes Attribute Meaning Set to Factory Defaults Upon Default Plug Detection If Enabled is checked, then an override/default plug functions as a default plug. When the module is rebooted with the plug inserted, it can be accessed at the IP address 169.254.1.1 and no password, and all parameter values are reset to defaults. A subscriber, technician, or other person who gains physical access to the module and uses an override/default plug cannot see or learn the settings that were previously configured in it. When the module is later rebooted with no plug inserted, the module uses the new values for any parameters that were changed and the default values for any that were not. If Disabled is checked, then an override/default plug functions as an override plug. When the module is rebooted with the plug inserted, it can be accessed at the IP address 169.254.1.1 and no password, and all previously configured parameter values remain and are displayed. A subscriber, technician, or other person who gains physical access to the module and uses an override/default plug can see and learn the settings. When the module is later rebooted with no plug inserted, the module uses the new values for any parameters that were changed and the previous values for any that were not. See Overriding Forgotten IP Addresses or Passwords on AP on Page 2-60.

Table 23 AP Unit Settings attributes Attribute Meaning Link Speeds From the drop-down list of options, select the type of link speed for the Ethernet connection. The default for this parameter is that all speeds are selected. The recommended setting is a single speed selection for all APs and SMs in the operator network.
Task 4: Configuring General and Unit settings Chapter 2: Configuration and alignment 2-48 pmp-0050 (May 2012) Attribute Meaning Ethernet Link Enable/Disable Specify whether to enable or disable Ethernet/802.3 connectivity on the wired port of the SM. This parameter has no effect on the wireless link. When you select Enable, this feature allows traffic on the Ethernet/802.3 port. This is the factory default state of the port. When you select Disable, this feature prevents traffic on the port. Typical cases of when you may want to select Disable include: The subscriber is delinquent with payment(s). You suspect that the subscriber is sending or flooding undesired broadcast packets into the network, such as when a virus is present in the subscriber's computing device. the subscriber's home router is improperly configured. Region Code This parameter allows you to set the region in which the radio will operate. When the appropriate region has been set, the radio automatically implements the applicable required Dynamic Frequency Selection (DFS) standard. The slave radio automatically inherits the DFS type of the master. This behavior ignores the value of the Region Code parameter in the slave, even when the value is None. Nevertheless, since future system software releases may read the value in order to configure some other region-sensitive feature(s), this parameter should always be set to the value that corresponds to the local region. Webpage Auto Update Enter the frequency (in seconds) for the web browser to automatically refresh the web-based interface. The default setting is 0. The 0 setting causes the web-based interface to never be automatically refreshed.
PMP 450 Configuration and User Guide Task 4: Configuring General and Unit settings pmp-0050 (May 2012) 2-49 Attribute Meaning Bridge Entry Timeout Specify the appropriate bridge timeout for correct network operation with the existing network infrastructure. Timeout occurs when the AP encounters no activity with the SM (whose MAC address is the bridge entry) within the interval that this parameter specifies. The Bridge Entry Timeout should be a longer period than the ARP (Address Resolution Protocol) cache timeout of the router that feeds the network. This parameter governs the timeout interval, even if a router in the system has a longer timeout interval. The default value of this field is 25 minutes. An inappropriately low Bridge Entry Timeout setting may lead to temporary loss of communication with some end users. SM Power Up Mode With No 802.3 Link This parameter is present in only PMP 100 Series SMs. Specify the default mode in which this SM will power up when the SM senses no Ethernet link. Select either Power Up in Aim Mode—the SM boots in an aiming mode. When the SM senses an Ethernet link, this parameter is automatically reset to Power Up in Operational Mode. When the module senses no Ethernet link within 15 minutes after power up, the SM carrier shuts off. Power Up in Operational Mode—the SM boots in Operational mode. The module attempts registration. This is the default selection. 2X Rate This parameter is present in only PMP 100 Series (FSK) SMs. Whatever value that you set in this parameter is overridden by a lock-down to 1X operation, if that is configured in the AP. In some cases, disabling this parameter facilitates aiming. Be aware that a lock-down to 1X in the AP locks down the uplink and downlink between the AP and all SMs in its sector, and thus would affect traffic and performance across the entire sector. Hence, a temporary lock-down for aiming is better done in the individual SM.
Task 4: Configuring General and Unit settings Chapter 2: Configuration and alignment 2-50 pmp-0050 (May 2012) Attribute Meaning Dynamic Rate Adapt This parameter is present in only PMP 400 Series (OFDM) SMs. Whatever value that you set in this parameter is overridden by a lock-down to 1X or 2X operation, if that is configured in the AP. As with the 2X Rate parameter in a PMP 100 Series SM, a temporary lock-down to facilitate aiming may be helpful. Be aware that a lock-down to 1X or 2X in the AP locks down the uplink and downlink between the AP and all SMs in its sector, and thus would affect traffic and performance across the entire sector. Hence, a temporary lock-down for aiming is better done in the individual SM. Frame Timing Pulse Gated If this SM extends the sync pulse to a BH master or an AP, select either Enable—If this SM loses sync from the AP, then do not propagate a sync pulse to the BH timing master or other AP. This setting prevents interference in the event that the SM loses sync. Disable—If this SM loses sync from the AP, then propagate the sync pulse to the BH timing master or other AP. Multicast Destination Address Using Link Layer Discovery Protocol (LLDP), a module exchanges multicast addresses with the device to which it is wired on the Ethernet interface. Although some switches (CMMmicro, for example) do not pass LLDP addresses upward in the network, a radio can pass it as the value of the Multicast Destination Address parameter value in the connected device that has it populated. In this way, an SM can report to Prizm, for example, the multicast address of a connected remote AP, and thus allow Prizm to discover that AP. To allow this, set the message mode in the remote AP to LLDP Multicast. Set this parameter in the SM to Broadcast. The SM will pass this address in broadcast mode, and the CMMmicro will pass the address upward in the network, since it does not discard addresses that it receives in broadcast mode. Where the AP is not behind another device, the Broadcast mode will allow discovery of the AP.

A network element passes time and date in any of the following scenarios: A connected CMM2 or CMM4 passes time and date (GPS time and date, if received). A connected CMMmicro passes the time and date (GPS time and date, if received), but only if both the CMMmicro is operating on CMMmicro Release 2.1 or later release. (These releases include NTP server functionality.) A separate NTP server is addressable from the AP. If the AP should obtain time and date from a CMMmicro, CMM4, or a separate NTP server, enter the IP address or DNS name of the CMM or NTP server on this tab. To force the AP to obtain time and date before the first (or next) 15-minute interval query of the NTP server, click Get Time through NTP. The polling of the NTP servers is done in a sequential fashion, and the polling status of each server is displayed in the NTP Update Log section of the Time Configuration page. An entry of 0.0.0.0 in any of the NTP Server fields indicates an unused server configuration. NTP Server(s) in Use Lists the IP addresses of servers used for NTP retrieval. Time Zone The Time Zone option may be used to offset the received NTP time to match the operator‘s local time zone. When set on the AP, the offset will be set for the entire sector (SMs will be notified of the current Time Zone upon initial registration). If a Time Zone change is applied, the SMs will be notified of the change in a best effort fashion, meaning some SMs may not pick up the change until the next re-registration. Time Zone changes are noted in the Event Log of the AP and SM. System Time The current time used by the system. Last NTP Time Update The last time that the system time was set via NTP.

PMP 450 Configuration and User Guide Task 5: Configuring security pmp-0050 (May 2012) 2-57 Encrypting radio transmissions Motorola fixed wireless broadband IP systems employ the following forms of encryption for security of the wireless link: DES–Data Encryption Standard, an over-the-air link option that uses secret 56-bit keys and 8 parity bits. AES–Advanced Encryption Standard, an extra-cost over-the-air link option that provides extremely secure wireless connections. AES uses 128-bit secret keys as directed by the government of the U.S.A. AES is not exportable and requires a special AP to process the large keys. DES Encryption Standard modules provide DES encryption. DES performs a series of bit permutations, substitutions, and recombination operations on blocks of data. DES Encryption does not affect the performance or throughput of the system. AES Encryption Motorola also offers fixed wireless broadband IP network products that provide AES encryption. AES uses the Rijndael algorithm and 128-bit keys to establish a higher level of security than DES. Because of this higher level of security, the government of the U.S.A. controls the export of communications products that use AES (among which the AES feature activation key is one) to ensure that these products are available in only certain regions and by special permit. The distributor or reseller can advise service providers about current regional availability. AES products are certified as compliant with the Federal Information Processing Standards (FIPS) in the U.S.A. The National Institute of Standards and Technology (NIST) in the U.S.A. has specified AES for significantly greater security than that which DES provides. NIST selected the AES algorithm for providing the best combination of security, performance, efficiency, implementation, and flexibility. NIST collaborates with industry to develop and apply technology, measurements, and standards. AES-DES Operability Comparisons This section describes the similarities and differences between DES and AES products, and the extent to which they may interoperate. Feature Availability AES products run the same software as DES products. Thus feature availability and functionality are and will continue to be the same, regardless of whether AES encryption is enabled. All interface screens are identical. However, when encryption is enabled on the Configuration screen the AES product provides AES encryption. the DES product provides DES encryption. AES and DES products use different FPGA (field-programmable gate array) loads. However, the AES FPGA will be upgraded as needed to provide new features or services similar to those available for DES products.
Task 5: Configuring security Chapter 2: Configuration and alignment 2-58 pmp-0050 (May 2012) Canopy DES products cannot be upgraded to AES. To have the option of AES encryption, the operator must purchase AES products. Interoperability AES and DES products do not interoperate when enabled for encryption. For example, An AES AP with encryption enabled cannot communicate with DES SMs. Similarly, an AES Backhaul timing master module with encryption enabled cannot communicate with a DES Backhaul timing slave module. However, if encryption is disabled, AES modules can communicate with DES modules. Managing module access by passwords Adding a User for Access to a Module From the factory, each module has a preconfigured administrator-level account in the name root, which initially requires no associated password. This is the same root account that you may have used for access to the module by telnet or ftp. When you upgrade a module: an account is created in the name admin. both admin and root inherit the password that was previously used for access to the module: o the Full Access password, if one was set. o the Display-Only Access password, if one was set and no Full Access password was set. If you use Prizm, do not delete the root account from any module. If you use an NMS that communicates with modules through SNMP, do not delete the root account from any module unless you first can confirm that the NMS does not rely on the root account for access to the modules. Each module supports four or fewer user accounts, regardless of account levels. The available levels are ADMINISTRATOR, who has full read and write permissions. This is the level of the root and admin users, as well as any other administrator accounts that one of them creates. INSTALLER, who has permissions identical to those of ADMINISTRATOR except that the installer cannot add or delete users or change the password of any other user. GUEST, who has no write permissions and only a limited view of General Status tab, and can log in as a user. From the factory default state, configure passwords for both the root and admin account at the ADMINISTRATOR permission level, using the Account, Change Users Password tab. (If you configure only one of these, then the other will still require no password for access into it and thus remain a security risk.) If you are intent on configuring only one of them, delete the admin account. The root account is the only account that CNUT uses to update and Prizm uses to manage the module.

Figure 9 Delete User tab of the SM Accounts that cannot be deleted are the current user's own account. the last remaining account of ADMINISTRATOR level. Overriding Forgotten IP Addresses or Passwords on AP and SM A small adjunctive product allows you to temporarily override some AP/SM settings and thereby regain control of the module. This override plug is needed for access to the module in any of the following cases: You have forgotten either o the IP address assigned to the module. o the password that provides access to the module. The module has been locked by the No Remote Access feature. You want local access to a module that has had the 802.3 link disabled in the Configuration page. You can configure the module such that, when it senses the override plug, it responds by either resetting the LAN1 IP address to 169.254.1.1, allowing access through the default configuration without changing the configuration, whereupon you will be able to view and reset any non-default values as you wish. resetting all configurable parameters to their factory default values. Acquiring the Override Plug You can either purchase or fabricate an override plug as follows. To purchase an override plug for a nominal fee, order the plug at http://www.best-tronics.com/motorola.htm. To fabricate an override plug, perform the following steps. 1 Install an RJ-11 6-pin connector onto a 6-inch length of CAT 5 cable 2 Pin out all 6-pins. 3 Short (solder together) Pins 4 and 6 on the other end. Do not connect any other wires to anything.

RESULT: The module boots with the default IP address of 169.254.1.1, password fields blank, and all other configuration values as previously set. 3 Wait approximately 30 seconds for the boot to complete. 4 Remove the override plug. 5 Set passwords and IP address as desired. 6 Change configuration values if desired. 7 Click the Save Changes button. 8 Click the Reboot button. Requiring SM Authentication Through the use of Prizm, a shared AP key, a BAM (Bandwidth and Authentication Manager) server, or an external RADIUS (Remote Authentication Dial In User Service) server, you can enhance network security by requiring SMs to authenticate when they register. Three keys and a random number are involved in authentication as follows: factory-set key in each SM. Neither the subscriber nor the network operator can view or change this key.
Task 5: Configuring security Chapter 2: Configuration and alignment 2-62 pmp-0050 (May 2012) authentication key, also known as authorization key and skey. This key matches in the SM and AP as the Authentication Key parameter, and in the Prizm database. random number, generated by Prizm or BAM and used in each attempt by an SM to register and authenticate. The network operator can view this number. session key, calculated separately by the SM and Prizm or BAM, based on both the authentication key (or, by default, the factory-set key) and the random number. Prizm or BAM sends the session key to the AP. The network operator cannot view this key. None of the above keys is ever sent in an over-the-air link during an SM registration attempt. However, with the assumed security risk, the operator can create and configure the Authentication Key parameter. See Authentication Key on Page 2-73. Filtering protocols and ports You can filter (block) specified protocols and ports from leaving the SM and entering the network. This protects the network from both intended and inadvertent packet loading or probing by network users. By keeping the specified protocols or ports off the network, this feature also provides a level of protection to users from each other. Protocol and port filtering is set per SM. Except for filtering of SNMP ports, filtering occurs as packets leave the SM. If an SM is configured to filter SNMP, then SNMP packets are blocked from entering the SM and, thereby, from interacting with the SNMP portion of the protocol stack on the SM. Port Filtering with NAT Enabled Where NAT is enabled, you can filter only the three user-defined ports. The following are example situations in which you can configure port filtering where NAT is enabled. To block a subscriber from using FTP, you can filter Ports 20 and 21 (the FTP ports) for both the TCP and UDP protocols. To block a subscriber from access to SNMP, you can filter Ports 161 and 162 (the SNMP ports) for both the TCP and UDP protocols. In only the SNMP case, filtering occurs before the packet interacts with the protocol stack. Protocol and Port Filtering with NAT Disabled Where NAT is disabled, you can filter both protocols and the three user-defined ports. Using the check boxes on the interface, you can either allow all protocols except those that you wish to block. block all protocols except those that you wish to allow. You can allow or block any of the following protocols: PPPoE (Point to Point Protocol over Ethernet)

The encryption used is DES for a DES module, and AES for an AES module. Before the Encrypt Downlink Broadcast feature is enabled on the AP, air link security should be enabled on the AP. Isolating SMs In an AP, you can prevent SMs in the sector from directly communicating with each other. In CMMmicro Release 2.2 or later and the CMM4, you can prevent connected APs from directly communicating with each other, which prevents SMs that are in different sectors of a cluster from communicating with each other. In the AP, the SM Isolation parameter is available in the General tab of the Configuration web page. In the drop-down menu for that parameter, you can configure the SM Isolation feature by any of the following selections: Disable SM Isolation (the default selection). This allows full communication between SMs. Block SM Packets from being forwarded. This prevents both multicast/broadcast and unicast SM-to-SM communication. Block and Forward SM Packets to Backbone. This not only prevents multicast/broadcast and unicast SM-to-SM communication but also sends the packets, which otherwise would have been handled SM to SM, through the Ethernet port of the AP. In the CMMmicro and the CMM4, SM isolation treatment is the result of how you choose to manage the port-based VLAN feature of the embedded switch, where you can switch all traffic from any AP to an uplink port that you specify. However, this is not packet level switching. It is not based on VLAN IDs. See the VLAN Port Configuration parameter in the dedicated user guide that supports the CMM product that you are deploying.
PMP 450 Configuration and User Guide Task 5: Configuring security pmp-0050 (May 2012) 2-65 Filtering management through Ethernet You can configure the SM to disallow any device that is connected to its Ethernet port from accessing the IP address of the SM. If you set the Ethernet Access Control parameter to Enabled, then no attempt to access the SM management interface (by http, SNMP, telnet, ftp, or tftp) through Ethernet can succeed. any attempt to access the SM management interface over the air (by IP address, presuming that LAN1 Network Interface Configuration, Network Accessibility is set to Public, or by link from the Session Status or Remote Subscribers tab in the AP) is unaffected. Allowing management only from specified IP addresses The Security tab of the Configuration web page in the AP and SM includes the IP Access Control parameter. You can specify one, two, or three IP addresses that should be allowed to access the management interface (by http, SNMP, telnet, ftp, or tftp). If you select IP Access Filtering Disabled, then management access is allowed from any IP address, even if the Allowed Source IP 1 to 3 parameters are populated. IP Access Filtering Enabled, and specify at least one address in the Allowed Source IP 1 to 3 parameter, then management access is limited to the specified address(es). If you intend to use Prizm to manage the element, then you must ensure that the IP address of the Prizm server is listed here. Configuring management IP by DHCP The IP tab in the Configuration web page of every radio contains a LAN1 Network Interface Configuration, DHCP State parameter that, if enabled, causes the IP configuration (IP address, subnet mask, and gateway IP address) to be obtained through DHCP instead of the values of those individual parameters. The setting of this DHCP state parameter is also viewable, but is not settable, in the Network Interface tab of the Home page. In the SM, this parameter is settable in the NAT tab of the Configuration web page, but only if NAT is enabled. in the IP tab of the Configuration web page, but only if the Network Accessibility parameter in the IP tab is set to Public. Denying All Remote Access Wherever the No Remote Access feature is enabled by the following procedure, physical access to the module is required for any change in the configuration of the module. any software upgrade in the module.

Task 5: Configuring security Chapter 2: Configuration and alignment 2-68 pmp-0050 (May 2012) Table 28 AP Security attributes Attribute Meaning Authentication Mode If the AP has authentication capability, then you can use this field to select from among the following authentication modes: Disabled—the AP requires no SMs to authenticate. Authentication Server —the AP requires any SM that attempts registration to be authenticated in BAM or Prizm before registration. AP PreShared Key - The AP acts as the authentication server to its SMs and will make use of a user-configurable pre-shared authentication key. The operator enters this key on both the AP and all SMs desired to register to that AP. There is also an option of leaving the AP and SMs at their default setting of using the ―Default Key‖. Due to the nature of the authentication operation, if you want to set a specific authentication key, then you MUST configure the key on all of the SMs and reboot them BEFORE enabling the key and option on the AP. Otherwise, if you configure the AP first, none of the SMs will be able to register. RADIUS AAA - When RADIUS AAA is selected, up to 3 Authentication Server (RADIUS Server) IP addresses and Shared Secrets can be configured. The IP address(es) configured here must match the IP address(es) of the RADIUS server(s). The shared secret(s) configured here must match the shared secret(s) configured in the RADIUS server(s). Servers 2 and 3 are meant for backup and reliability, not for splitting the database. If Server 1 doesn‘t respond, Server 2 is tried, and then server 3. If Server 1 rejects authentication, the SM is denied entry to the network, and does not progress trying the other servers. Authentication Server DNS Usage The management DNS domain name may be toggled such that the name of the authentication server only needs to be specified and the DNS domain name is automatically appended to that name. Authentication Server 1 to 5 Enter the IP address of the authentication server (RADIUS, Prizm, or BAM) and the Shared Secret configured in the authentication server. When Authentication Mode RADIUS AAA is selected, the default value of Shared Secret is ―CanopySharedSecret‖. The Shared Secret may consist of up to 32 ASCII characters. Radius Port This field allows the operator to configure a custom port for RADIUS server communication. The default value is 1812. Authentication Key The authentication key is a 32-character hexadecimal string used when Authentication Mode is set to AP PreShared Key. By default, this key is set to 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF.
PMP 450 Configuration and User Guide Task 5: Configuring security pmp-0050 (May 2012) 2-69 Attribute Meaning Select Key This option allows operators to choose which authentication key is used: Use Key above means that the key specified in Authentication Key is used for authentication Use Default Key means that a default key (based off of the SM‘s MAC address) will be used for authentication Encryption Specify the type of airlink security to apply to this AP: Encryption Disabled provides no encryption on the air link. This is the default mode. Encryption Enabled provides encryption, using a factory-programmed secret key that is unique for each module. Encrypt Downlink Broadcast When Encryption Enabled is selected in the Airlink Security parameter (described above) and Enable is selected in the Encrypt Downlink Broadcast parameter, the AP encrypts downlink broadcast packets as DES where the AP is DES capable. AES where the AP is AES capable.

IP Access Control You can permit access to the AP from any IP address (IP Access Filtering Disabled) or limit it to access from only one, two, or three IP addresses that you specify (IP Access Filtering Enabled). If you select IP Access Filtering Enabled, then you must populate at least one of the three Allowed Source IP parameters or have no access permitted from any IP address, including access and management by Prizm. Allowed Source IP 1 to 3 If you selected IP Access Filtering Enabled for the IP Access Control parameter, then you must populate at least one of the three Allowed Source IP parameters or have no access permitted to the AP from any IP address. You may populate as many as all three. If you selected IP Access Filtering Disabled for the IP Access Control parameter, then no entries in this parameter are read, and access from all IP addresses is permitted.

For alpha characters in this hex key, use only upper case. Select Key The Use Default Key selection specifies the predetermined key for authentication in BAM or Prizm. The Use Key above selection specifies the 32-digit hexadecimal key that is permanently stored on both the SM and the BAM or Prizm database. The SM and BAM or Prizm pad the key of any length by the addition of leading zeroes, and if the entered keys match, authentication attempts succeed. However, Motorola recommends that you enter 32 characters to achieve the maximal security from this feature. Enforce Authentication The SM may enforce authentication types of AAA and BAM/PreSharedKey. The SM will not finish the registration process if the AP is not using the configured authentication method (and the SM will lockout the AP for 15 minutes). Phase 1 The protocols supported for the Phase 1 (Outside Identity) phase of authentication are EAPTTLS (Extensible Authentication Protocol Tunneled Transport Layer Security) or MSCHAPv2 (Microsoft Challenge-Handshake Authentication Protocol version 2). Phase 2 Select the desired Phase 2 (Inside Identity) authentication protocol from the Phase 2 options of PAP (Password Authentication Protocol), CHAP (Challenge Handshake Authentication Protocol), and MSCHAP (Microsoft‘s version of CHAP, version 2 is used).

This selection disables access through this port to via http (the GUI), SNMP, telnet, ftp, and tftp. With this selection, management access is available through only the RF interface via either an IP address (if Network Accessibility is set to Public on the SM) or the Session Status or Remote Subscribers tab of the AP. This setting does not prevent a device connected to the Ethernet port from accessing the management interface of other SMs in the network. To prevent this, use the IP Access Filtering Enabled selection in the IP Access Control parameter of the SMs in the network. See IP Access Control below. If you want to allow management access through the Ethernet port, select Ethernet Access Enabled. This is the factory default setting for this parameter. IP Access Control You can permit access to the SM from any IP address (IP Access Filtering Disabled) or limit it to access from only one, two, or three IP addresses that you specify (IP Access Filtering Enabled).

PMP 450 Configuration and User Guide Task 6: Configuring radio parameters pmp-0050 (May 2012) 2-81 Attribute Meaning Cyclic Prefix OFDM technology uses a cyclic prefix, where a portion of the end of a symbol (slot) is repeated at the beginning of the symbol to allow multi-pathing to settle before receiving the desired data. A 1/4 cyclic prefix means that for every 4 bits of throughput data transmitted, an additional bit is used. A 1/8 cyclic prefix means that for every 8 bits of throughput data transmitted, an additional bit is used, and a 1/16 cyclic prefix means that for every 16 bits of throughput data transmitted, an additional bit is used. PMP 450 radios use a default cyclic prefix of 1/4 that is configurable by the operator to 1/8 or 1/16. The cyclic prefix is set on the Configuration > Radio page of the AP. Changing the default from 1/4 to 1/8 can increase throughput by ~12% (assuming a 75% duty cycle ) in installations with low multipath conditions. Moving from a 1/8 cyclic prefix to a 1/16 cyclic prefix can increase throughput by another ~12%. It is recommended to test 1/8 or 1/16 cyclic prefix configurations to determine actual performance based on RF conditions. Deploying networks using 1/8 or 1/16 cyclic prefixes is feasible in all but the worst multi-path environments (urban areas with buildings causing many reflections). During installation use Link Tests to confirm link quality per standard installation and alignment procedures. If a Link Test shows low throughput or low efficiency, consider changing the Cyclic Prefix to 1/4 on both the AP and SM along with other standard installation troubleshooting procedures such as re-aiming, off-axis aiming, changing location, raising or lowing the height of the radio, adjusting the Transmission Power up or down, or identifying and mitigating sources of interference. The cyclic prefix must be set the same on both the AP and the SM. If they don‘t match, the SM will not register to the AP. Color Code Specify a value from 0 to 254. For registration to occur, the color code of the SM and the AP must match. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each sector a different color code. Color code allows you to force an SM to register to only a specific AP, even where the SM can communicate with multiple APs. The default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes).
Task 6: Configuring radio parameters Chapter 2: Configuration and alignment 2-82 pmp-0050 (May 2012) Attribute Meaning Subscriber Color Code Rescan (When not on a Primary Color Code) This timer may be utilized to initiate SM rescans in order to register to an AP configured with the SM‘s primary color code. The time (in minutes) for a subscriber to rescan (if this AP is not configured with the SM‘s primary color code). This timer will only fire once – if the Subscriber Color Code Wait Period for Idle timer is configured with a nonzero value and the Subscriber Color Code Rescan expires, the Subscriber Color Code Wait Period for Idle will be started. If the Subscriber Color Code Wait Period for Idle timer is configured with a zero value and the Subscriber Color Code Rescan timer expires, the SM will immediately go into rescan mode Subscriber Color Code Wait Period for Idle The time (in minutes) for a subscriber to rescan while idle (if this AP is not configured with the SM‘s primary color code). This timer will fire periodic events. The fired event determines if any RF unicast traffic (either inbound or outbound) has occurred since the last event. If the results of the event determine that no RF unicast traffic has occurred (SM is idle), then the subscriber will rescan. Installation Color Code With this feature enabled on the AP and SM, operators may install and remotely configure SMs without having to configure matching color codes between the modules. While the SM is accessible for configuration from above the AP (for remote provisioning) and below the SM (for local site provisioning), no user data is passed over the radio link. SMs with Installation Color Code enabled will first try any configured Color Code values first, then will use the Installation Color Code feature as a last result to connect to the AP. The status of the Installation Color Code can be viewed on the AP Eval web GUI page, and when the SM is registered using the Installation Color Code the message ―SM is registered via ICC – Bridging Disabled!‖ is displayed in red on every SM GUI page. The Installation Color Code parameter is configurable without a radio reboot for both the AP and SM. If an SM is registered via Installation Color Code and the feature is then disabled, operators will need to reboot the SM or force it to reregister (i.e. using the Rescan APs functionality on the AP Eval page). Power Save Mode Select either Enabled (the default), to reduce module power consumption by approximately 10% without affecting the transmitter output power. This is the recommended setting. Disabled, to continue normal power consumption, but do so only under guidance from technical support. Sector ID Specify a number in the range 1 to 6 to associate with this AP. The Sector ID setting does not affect the operation of the AP. On the AP Evaluation tab of the Tools page in the SM, the Sector ID field identifies the AP that the SM sees. The following steps may be useful: 1. Assign a unique Sector ID to each sector in an AP cluster. 2. Repeat the assignment pattern throughout the entire system.
PMP 450 Configuration and User Guide Task 6: Configuring radio parameters pmp-0050 (May 2012) 2-83 Attribute Meaning Signal to Noise Ratio Calculation Enabling this parameter allows operators to use Signal-to-Noise calculations to monitor link quality. The Signal-to-Noise Ratio may be monitored on the AP‘s Session Status page, Link Capacity Test page, and Link Status page. See the table below for required Signal-to-Noise Ratios required for each modulation state: Modulation Downlink Uplink 1X 7 dB 9 dB 2X 15 dB 16 dB 3X 23 dB 24 dB Note that locking a radio a lower modulation may result in a lower SNR ratio reading that a higher modulation. For example an AP/SM pair that is getting a SNR of 23/29 dB for downlink/uplink when modulation is set to 1X/2X/3X gets 22/27 dB for a setting of 1X/2X. And when set to 1X (No rate adapt) the SNR reads 12/18 dB. For highest SNR calculation the rate adapt must be set to its highest rate adapt modulation. Max Range Enter a number of miles (or kilometers divided by 1.61, then rounded to an integer) for the furthest distance from which an SM is allowed to register to this AP. Do not set the distance to any greater number of miles. A greater distance does not increase the power of transmission from the AP. can reduce aggregate throughput. Regardless of this distance, the SM must meet the minimum requirements for an acceptable link. If the AP is in cluster, then you must set this parameter on all other APs in the cluster exactly the same, except as described in the NOTE admonition below. The default value of this parameter is 2 miles (3.2 km). For the PMP 450 Series AP, the typical maximum range achievable depends on the operation mode as follows: 5 miles (8 km) in 1X operation 2.5 miles (4 km) in 2X operation 1.25 miles (2 km) in 3X operation A value of 15 for this parameter decreases the number of available data slots by 1. With a higher value, the number is further decreased as the AP compensates for the expected additional air delay.
Task 6: Configuring radio parameters Chapter 2: Configuration and alignment 2-84 pmp-0050 (May 2012) Attribute Meaning Downlink Data Specify the percentage of the aggregate throughput for the downlink (frames transmitted from the AP to the subscriber). For example, if the aggregate (uplink and downlink total) throughput on the AP is 6 Mb, then 75% specified for this parameter allocates 4.5 Mb for the downlink and 1.5 Mb for the uplink. The default for this parameter is 75%. You must set this parameter exactly the same for all APs in a cluster.
PMP 450 Configuration and User Guide Task 6: Configuring radio parameters pmp-0050 (May 2012) 2-85 Attribute Meaning Control Slots Field results have indicated that, in general, systems perform better with a slightly higher number of control slots than previously recommended. If you are experiencing latency or SM-servicing issues, increasing the number of control slots may increase system performance, depending on traffic mix over time. Use care when changing the control slot configuration of only some APs, because changes affect the uplink/downlink ratio and can cause collocation issues. Change control slot configuration in an operating, stable system cautiously and with a back-out plan. After changing a control slot configuration, monitor the system closely for problems as well as improvements in system performance.. Table 39: Control slot settings for all OFDM APs in cluster Number of SMs that Register to the AP Number of Control Slots Recommended 1 to 10 2 11 to 50 4 51 to 150 6 151 to 200 8 This field indicates the number of (reserved) control slots configured by the operator. Control slots are half the size of data slots. The SM uses reserved control slots and unused data slots for bandwidth requests. If too few reserved control slots are specified, then latency increases in high traffic periods. If too many are specified, then the maximum capacity is unnecessarily reduced. In a typical cluster, each AP should be set to the same number of control slots to assure proper timing in the send and receive cycles. However, where high incidence of small packets exists, as in a sector that serves several VoIP streams, additional control slots may provide better results. For APs in a cluster of mismatched control slots settings, or where OFDM and FSK APs of the same frequency band are collocated, use the frame calculator.
Task 6: Configuring radio parameters Chapter 2: Configuration and alignment 2-86 pmp-0050 (May 2012) Attribute Meaning Broadcast Repeat Count The default is 2 repeats (in addition to the original broadcast packet, for a total of 3 packets sent for every one needed), and is settable to 1 or 0 repeats (2 or 1 packets for every broadcast). ARQ (Automatic Repeat reQuest) is not present in downlink broadcast packets, since it would cause unnecessary uplink traffic from every SM for each broadcast packet. For successful transport without ARQ, the AP repeats downlink broadcast packets. The SMs filter out all repeated broadcast packets and, thus, do not transport further. The default of 2 repeats is optimum for typical uses of the network as an internet access system. In applications with heavy download broadcast such as video distribution, overall throughput is significantly improved by setting the repeat count to 1 or 0. This avoids flooding the downlink with repeat broadcast packets. Transmitter Output Power Nations and regions may regulate transmitter output power. For example 5.7-GHz modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance. The professional installer of the equipment has the responsibility to maintain awareness of applicable regulations. calculate the permissible transmitter output power for the module. confirm that the initial power setting is compliant with national or regional regulations. confirm that the power setting is compliant following any reset of the module to factory defaults. External Gain This value represents the amount of gain introduced by an external antenna. If your network operates in a region in which DFS shutdown capability is required, and you do not see this parameter, perform the following steps: 1. Click the General tab. 2. Set the Region Code parameter from its drop-down list. 3. Click the Save Changes button. 4. Click the Reboot button. 5. Click the Radio tab.

Table 41 SM Radio attributes Attribute Meaning Custom Radio Frequency Scan Selection List Check any frequency that you want the SM to scan for AP transmissions. The frequency band of the SM affects what channels you should select. In a 5.7-GHz SM, this parameter displays both ISM and U-NII frequencies. If you select all frequencies that are listed in this field (default selections), then the SM scans for a signal on any channel. If you select only one, then the SM limits the scan to that channel. Channel Bandwidth The channel size used by the radio for RF transmission. This parameter is dictated by the AP‘s settings.
PMP 450 Configuration and User Guide Task 6: Configuring radio parameters pmp-0050 (May 2012) 2-89 Attribute Meaning Color Code 1 to 10 Color code allows you to force the SM to register to only a specific AP, even where the SM can communicate with multiple APs. For registration to occur, the color code of the SM and the AP must match. Specify a value from 0 to 254. Color code is not a security feature. Instead, color code is a management feature, typically for assigning each sector a different color code. The default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). SMs may be configured with up to 10 color codes. These color codes can be tagged as Primary, Secondary, or Tertiary, or Disable. When the SM is scanning for APs, it will first attempt to register to an AP that matches one of the SM‘s primary color codes. Failing that, the SM will continue scanning and attempt to register to an AP that matches one of the SM‘s secondary color codes. Failing that, the SM will continue scanning and attempt to register to an AP that matches one of the SM‘s tertiary color codes. This is all done in the scanning mode of the SM and will repeat until a registration has occurred. Color codes in the same priority group are treated equally. For example, all APs matching one of the SM‘s primary color codes are analyzed equally. Likewise, this evaluation is done for the secondary and tertiary groups in order. The analysis for selecting an AP within a priority group is based on various inputs, including signal strength and number of SMs already registered to each AP. The first color code in the configuration is the pre-Release 9.5 color code. Thus, it is always a primary color code for legacy reasons. The color codes can be disabled, with the exception of the first color code. Installation Color Code With this feature enabled on the AP and SM, operators may install and remotely configure SMs without having to configure matching color codes between the modules. While the SM is accessible for configuration from above the AP (for remote provisioning) and below the SM (for local site provisioning), no user data is passed over the radio link. SMs with Installation Color Code enabled will first try any configured Color Code values first, then will use the Installation Color Code feature as a last result to connect to the AP. The status of the Installation Color Code can be viewed on the AP Eval web GUI page, and when the SM is registered using the Installation Color Code the message ―SM is registered via ICC – Bridging Disabled!‖ is displayed in red on every SM GUI page. The Installation Color Code parameter is configurable without a radio reboot for both the AP and SM. If an SM is registered via Installation Color Code and the feature is then disabled, operators will need to reboot the SM or force it to reregister (i.e. using the Rescan APs functionality on the AP Eval page).
Task 6: Configuring radio parameters Chapter 2: Configuration and alignment 2-90 pmp-0050 (May 2012) Attribute Meaning Large VC data Q Certain applications such as video Surveillance cameras operate by sending bursts of IP traffic upstream. Some systems will send short bursts of packets at over 50 Mbps and then be idle for some period of time and then send another burst of data. In order for the RF interface of a radio to accommodate these bursts of traffic, there is a configurable parameter on SM radios to operate with a large input queue at the radio‘s data VC. This large queue allows packets which arrive at a rate greater than the radio link capacity to be stored in this deep queue until the radio is ready to transmit them. The queue size has been optimized to allow large packets to be stored just long enough so that there is always data available to be transmitted, but not large enough to cause packets to sit in a queue for a second or more. Configuration of this parameter is shown on the Configuration => Radio web page on the SM.. If an operator is experiencing packet loss in the uplink due to bursting IP traffic and the overall traffic rate is less than or equal to the uplink capacity of the radio system, then the large VC data Q should be enabled. Signal to Noise Ratio Calculation Enabling this parameter allows operators to use Signal-to-Noise calculations to monitor link quality. The Signal-to-Noise Ratio may be monitored on the SM‘s Home page, Link Capacity Test page, and Link Status page. See the table below for required Signal-to-Noise Ratios required for each modulation state: Modulation Downlink Uplink 1X 7 dB 9 dB 2X 15 dB 16 dB 3X 23 dB 24 dB Note that locking a radio a lower modulation may result in a lower SNR ratio reading that a higher modulation. For example an AP/SM pair that is getting a SNR of 23/29 dB for downlink/uplink when modulation is set to 1X/2X/3X gets 22/27 dB for a setting of 1X/2X. And when set to 1X (No rate adapt) the SNR reads 12/18 dB. For highest SNR calculation the rate adapt must be set to its highest rate adapt modulation.

Task 11: Configuring quality of service Chapter 2: Configuration and alignment 2-106 pmp-0050 (May 2012) Task 11: Configuring quality of service Maximum Information Rate (MIR) Parameters Point-to-multipoint links use the following four MIR parameters for bandwidth management: Sustained Uplink Data Rate (kbps) Uplink Burst Allocation (kb) Sustained Downlink Data Rate (kbps) Downlink Burst Allocation (kb) You can independently set each of these parameters per AP or per SM. Token Bucket Algorithm The software uses a token bucket algorithm that stores credits (tokens) for the SM to spend on bandwidth for reception or transmission. drains tokens during reception or transmission. refills with tokens at the sustained rate set by the network operator. For each token, the SM can send toward the network in the uplink (or the AP can send toward the SM in the downlink) an equivalent number of kilobits. Two buckets determine the permitted throughput: one in the SM for uplink and one in the AP for downlink. The applicable set of Uplink Burst Allocation and Downlink Burst Allocation parameters determine the number of tokens that can fill each bucket. When the SM transmits (or the AP transmits) a packet, the equivalent number of tokens is removed from the uplink (or downlink) bucket. Except when full, the bucket is continuously being refilled with tokens at rates that the applicable set of Sustained Uplink Data Rate and Sustained Downlink Data Rate parameters specify. The bucket often drains at a rate that is much faster than the sustained data rate but can refill at only the sustained data rate. Thus, the effects of the allocation and rate parameters on packet delay are as follows: the burst allocation affects how many kilobits are processed before packet delay is imposed. the sustained data rate affects the packet delay that is imposed. Which set of these MIR parameters are applicable depends on the interactions of other parameter values. Also, where the Configuration Source parameter setting in the AP specifies that BAM values should be used, they are used only if Prizm is configured to send the values that it stores for the MIR parameters.
PMP 450 Configuration and User Guide Task 11: Configuring quality of service pmp-0050 (May 2012) 2-107 MIR Data Entry Checking Uplink and downlink MIR is enforced as shown in Figure 22. In these figures, entry refers to the setting in the data rate parameter, not the burst allocation parameter. Figure 22 Uplink and downlink rate caps adjusted to apply aggregate cap uplink cap enforced = uplink entry x aggregate cap for the SMuplink entry + downlink entry downlink cap enforced = downlink entry x aggregate cap for the SMuplink entry + downlink entry For example, in the SM, if you set the Sustained Uplink Data Rate parameter to 2,000 kbps and the Sustained Downlink Data Rate parameter to 10,000 kbps, then the uplink and downlink MIR that will be enforced for the SM can be calculated as shown in Figure 23. Figure 23 Uplink and downlink rate cap adjustment example uplink cap enforced = 2,000 kbps x 7,000 kbps2,000 kbps + 10,000 kbps = 1,167 kbps downlink cap enforced = 10,000 kbps x 7,000 kbps2,000 kbps + 10,000 kbps = 5,833 kbps In this example case, the derived 1,167-kbps uplink and 5,833-kbps downlink MIR sum to the fixed 7,000-kbps aggregate cap of the SM. Committed Information Rate The Committed Information Rate (CIR) capability feature enables the service provider to guarantee to any subscriber that bandwidth will never decrease to below a specified minimum, unless CIR is oversubscribed. Bandwidth can be, and typically will be, higher than the minimum, but this guarantee helps the WISP to attract and retain subscribers. In BAM Release 2.1 and in Prizm Release 2.0, CIR configuration is supported as follows: The GUI allows you to view and change CIR configuration parameters per SM.
Task 11: Configuring quality of service Chapter 2: Configuration and alignment 2-108 pmp-0050 (May 2012) When an SM successfully registers and authenticates, if BAM or Prizm has CIR configuration data for the SM, then messages make the CIR configuration available to the SM, depending on the Configuration Source setting. The operator can disable the CIR feature in the SM without deleting the CIR configuration data. Bandwidth from the SM Perspective In the SM, normal web browsing, e-mail, small file transfers, and short streaming video are rarely rate limited with practical bandwidth management (QoS) settings. When the SM processes large downloads such as software upgrades and long streaming video or a series of medium-size downloads, the bucket rapidly drains, the burst limit is reached, and some packets are delayed. The subscriber experience is more affected in cases where the traffic is more latency sensitive. Interaction of Burst Allocation and Sustained Data Rate Settings If the Burst Allocation is set to 1200 kb and the Sustained Data Rate is set to 128 kbps, a data burst of 1000 kb is transmitted at full speed because the Burst Allocation is set high enough. After the burst, the bucket experiences a significant refill at the Sustained Data Rate. This configuration uses the advantage of the settable Burst Allocation. If both the Burst Allocation and the Sustained Data Rate are set to 128 kb, a burst is limited to the Burst Allocation value. This configuration does not take advantage of the settable Burst Allocation. If the Burst Allocation is set to 128 kb and the Sustained Data Rate is set to 256 kbps, the actual rate will be the burst allocation (but in kbps). As above, this configuration does not take advantage of the settable Burst Allocation. High-priority Bandwidth To support low-latency traffic such as VoIP (Voice over IP) or video, the system implements a high-priority channel. This channel does not affect the inherent latencies in the system but allows high-priority traffic to be immediately served. The high-priority pipe separates low-latency traffic from traffic that is latency tolerant, such as standard web traffic and file downloads. The number of channels available to the AP is reduced by the number of SMs configured for the high-priority channel. With this feature enabled on all SMs, an AP can support 100 SMs (instead of 200). A module prioritizes traffic by reading the Low Latency bit (Bit 3) in the IPv4 Type of Service (ToS) byte in a received packet. Bit 3 is set by a device outside the system. reading the 802.1p field of the 802.1Q header in a received packet, where VLAN is enabled on the module.
PMP 450 Configuration and User Guide Task 11: Configuring quality of service pmp-0050 (May 2012) 2-109 comparing the 6-bit Differentiated Services Code Point (DSCP) field in the ToS byte of a received packet to a corresponding value in the Diffserv tab of the Configuration page of the module. A packet contains no flag that indicates whether the encoding is for the Low Latency bit or the DSCP field. For this reason, you must ensure that all elements in your trusted domain, including routers and endpoints, set and read the ToS byte with the same scheme. Modules monitor ToS bytes with DSCP fields, but with the following differences: The 6-bit length of the field allows it to specify one of 64 service differentiations. These correlate to 64 individual (CodePoint) parameters in the Diffserv tab of the Configuration page. Per RFC 2474, 3 of these 64 are preset and cannot be changed. (See http://www.faqs.org/rfcs/rfc1902.html.) For any or all of the remaining 61 CodePoint parameters, you can specify a value of o 0 through 3 for low-priority handling. o 4 through 7 for high-priority handling. Ensure that your Differentiated Services domain boundary nodes mark any entering packet, as needed, so that it specifies the appropriate Code Point for that traffic and domain. This prevents theft of service level. An example of the Diffserv tab in the Configuration page and parameter descriptions are provided under DiffServ Tab of the AP on Page 2-116. This tab and its rules are identical from module type to module type. However, any of the 61 configurable Code Points can be set to a different value from module to module, thus defining unique per-hop behavior for some traffic. This tab in the AP sets the priorities for the various packets in the downstream (sent from the public network). This tab in the SM sets the priorities for the various packets in the upstream (sent to the public network). Typically, some SMs attach to older devices that use the ToS byte as originally formatted, and others to newer devices that use the DSCP field. The default values in the Diffserv tab allow your modules to prioritize traffic from the older devices roughly the same as they traditionally have. However, these default values may result in more high-priority traffic as DSCP fields from the newer devices are read and handled. So, after making any changes in the Diffserv tab, carefully monitor the high-priority channel for high packet rates in SMs that you have identified as those to initially set and watch. across your network when you have broadly implemented Code Point values, such as via SNMP.

See the dedicated user guide that supports the CMM that you are deploying. However, the requirements do not affect the maximums for the CMM2. Packets that have a priority of 4 to 7 in either the DSCP or a VLAN 802.1p tag are automatically sent on the high-priority channel, but only where the high-priority channel is enabled. Setting the Configuration Source The AP includes a Configuration Source parameter, which sets where SMs that register to the AP are controlled for MIR, VLAN, the high-priority channel, and CIR as follows. The Configuration Source parameter affects the source of: all MIR settings: o Sustained Uplink Data Rate

Where Authentication Server, then SM is the indication, parameters for which Authentication Server does not send values are obtained from the SM. This is the case where the Authentication Server server is operating on a Authentication Server release that did not support the feature. This is also the case where the feature enable/disable flag in Authentication Server is set to disabled. The values are those previously set or, if none ever were, then the default values. Where Authentication Server is the indication, values in the SM are disregarded. Where SM is the indication, values that Authentication Server sends for the SM are disregarded. The high-priority channel is unavailable to Series P7 and P8 SMs. For any SM whose Authentication Mode parameter is not set to Authentication Required, the listed settings are derived as shown: Table 51 Where feature values are obtained for an SM with authentication disabled Configuration Source Setting in the AP Values are obtained from MIR Values VLAN Values High Priority Channel State CIR Values Authentication Server AP AP AP AP SM SM SM SM SM Authentication Server+SM SM SM SM SM For the case where the Configuration Source parameter in the AP is set to Authentication Server, the SM stores a value for the Dynamic Learning VLAN parameter that differs from its factory default. When Prizm does not send VLAN values (because VLAN Enable is set to No in Prizm), the SM uses this stored Disable value for Dynamic Learning. shows the following in the VLAN Configuration web page: o either Enable or Disable as the value of the Dynamic Learning parameter. o Allow Learning : No under Active Configuration.

If the SM is set to factory defaults, then this value is Enable. shows under Active Configuration the result of the configured value in the SM. For example, if the SM is set to factory defaults, then the VLAN Configuration page shows Allow Learning : Yes.

For many other system designs, especially typical internet access networks, leave the Broadcast Downlink CIR at the default. Broadcast Downlink CIR is closely related to the Broadcast Repeat Count parameter, which is settable in the Radio tab of the Configuration page in the AP: when the Broadcast Repeat Count is changed, the total of available bandwidth is also changed, since packets are being sent one, two, or three times, according to the setting in the Broadcast Repeat Count parameter. (See Broadcast Repeat Count on Page 2-86.)

Task 12: Configuring a RADIUS server Chapter 2: Configuration and alignment 2-122 pmp-0050 (May 2012) Task 12: Configuring a RADIUS server Configuring a RADIUS AAA (Authentication, Authorization, and Accounting) server in a PMP 450 network is optional, but can provide added security, increase ease of network management and provide usage-based billing data. Understanding RADIUS for PMP 450 PMP 450 modules include support for the RADIUS (Remote Authentication Dial In User Service) protocol supporting Authentication, Authorization, and Accounting (AAA). RADIUS Functions RADIUS protocol support provides the following functions: SM Authentication allows only known SMs onto the network (blocking ―rogue‖ SMs), and can be configured to ensure SMs are connecting to a known network (preventing SMs from connecting to ―rogue‖ APs). RADIUS authentication is used for SMs, but is not used for APs. SM Authorization configures authenticated SMs with MIR (Maximum Information Rate), CIR (Committed Information Rate), High Priority, and VLAN (Virtual LAN) parameters from the RADIUS server when an SM registers to an AP. SM Accounting provides support for RADIUS accounting messages for usage-based billing. This accounting includes indications for subscriber session establishment, subscriber session disconnection, and bandwidth usage per session for each SM that connects to the AP. Centralized AP and SM user name and password management allows AP and SM usernames and access levels (Administrator, Installer, Technician) to be centrally administered in the RADIUS server instead of on each radio and tracks access events (logon/logoff) for each username on the RADIUS server. This accounting does not track and report specific configuration actions performed on radios or pull statistics such as bit counts from the radios. Such functions require an Element Management System (EMS) such as Cambium Networks Wireless Manager. This accounting is not the ability to perform accounting functions on the subscriber/end user/customer account. Framed IP allows operators to use a RADIUS server to assign management IP addressing to SM modules (framed IP address). Tested RADIUS Servers The Canopy RADIUS implementation has been tested and is supported on FreeRADIUS, Version 2.1.8 Aradial RADIUS, Version 5.1.12
PMP 450 Configuration and User Guide Task 12: Configuring a RADIUS server pmp-0050 (May 2012) 2-123 Note, Aradial 5.3 has a bug that prevents ―remote device login‖, so doesn‘t support the user name and password management feature. Choosing Authentication Mode and Configuring for Authentication Servers - AP On the AP‘s Configuration > Security tab, select the RADIUS AAA Authentication Mode. The following describes the other Authentication Mode options for reference, and then the RADIUS AAA option. Disabled: Requires no authentication. Any SM (except an SM that itself has been configured to require RADIUS authentication by enabling Enforce Authentication as described below) will be allowed to register to the AP. Authentication Server: Authentication Server in this instance refers to BAM or Prizm. Authentication will be required for an SM to register to the AP. Only SMs listed by MAC address in the BAM or Prizm database will be allowed to register to the AP. AP Pre-Shared Key: Canopy offers a pre-shared key authentication option. In this case, an identical key must be entered in the Authentication Key field on the AP‘s Configuration > Security tab and in the Authentication Key field on each desired SM‘s Configuration > Security tab. RADIUS AAA: To support RADIUS authentication of SMs, on the AP‘s Configuration > Security tab select RADIUS AAA. Only properly configured SMs with a valid certificate will be allowed to register to the AP. When RADIUS AAA is selected, up to 3 Authentication Server (RADIUS Server) IP addresses and Shared Secrets can be configured. The IP address(es) configured here must match the IP address(es) of the RADIUS server(s). The shared secret(s) configured here must match the shared secret(s) configured in the RADIUS server(s). Servers 2 and 3 are meant for backup and reliability, not splitting the database. If Server 1 doesn‘t respond, Server 2 is tried, and then server 3. If Server 1 rejects authentication, the SM is denied entry to the network, and does not progress trying the other servers. The default IP address is 0.0.0.0. The default Shared Secret is ―CanopySharedSecret‖. The Shared Secret can be up to 32 ASCII characters (no diacritical marks or ligatures, for example).
Task 12: Configuring a RADIUS server Chapter 2: Configuration and alignment 2-124 pmp-0050 (May 2012) Figure 28 Security tab of the AP SM Authentication Mode – Require RADIUS or Follow AP If it is desired that an SM will only authenticate to an AP that is using RADIUS, on the SM‘s Configuration Security tab set Enforce Authentication to AAA. With this enabled, an SM will not register to an AP that has any Authentication Mode other than RADIUS AAA selected. If it is desired that an SM use the authentication method configured on the AP it is registering to, set Enforce Authentication to Disabled. With Enforce Authentication disabled, an SM will attempt to register using whichever Authentication Mode is configured on the AP it is attempting to register to. Note, requiring SMs to use RADIUS by enabling Enforce Authentication avoids the security issue of SMs possibly registering to ―rogue‖ APs which have authentication disabled.
PMP 450 Configuration and User Guide Task 12: Configuring a RADIUS server pmp-0050 (May 2012) 2-125 Figure 29 Security tab of the SM SM - Phase 1 (Outside Identity) parameters and settings The protocols supported for the Phase 1 (Outside Identity) phase of authentication are eapttls (Extensible Authentication Protocol Tunneled Transport Layer Security) and eapMSChapV2 (Extensible Authentication Protocol – Microsoft Challenge-Handshake Authentication Protocol). Configure an outer Identity in the Username field. This must match the Phase 1/Outer Identity username configured in the RADIUS server. The default Phase 1/Outer Identity Username is ―anonymous‖. The Username can be up to 128 non-special (no diacritical markings) alphanumeric characters. If Realms are being used in the RADIUS system (eapttls only), select Enable Realm and configure an outer identity in the Identity field and a Realm in the Realm field. These must match the Phase 1/Outer Identity and Realm configured in the RADIUS server. The default Identity is ―anonymous‖. The Identity can be up to 128 non-special (no diacritical markings) alphanumeric characters. The default Realm is ―canopy.net‖. The Realm can also be up to 128 non-special alphanumeric characters.
Task 12: Configuring a RADIUS server Chapter 2: Configuration and alignment 2-126 pmp-0050 (May 2012) SM - Phase 2 (Inside Identity) parameters and settings If using eapttls for Phase 1 authentication, select the desired Phase 2 (Inside Identity) authentication protocol from the Phase 2 options of PAP (Password Authentication Protocol), CHAP (Challenge Handshake Authentication Protocol), and MSCHAPv2 (Microsoft‘s version of CHAP). The protocol must be consistent with the authentication protocol configured on the RADIUS server. Enter a Username for the SM. This must match the username configured for the SM on the RADIUS server. The default Username is the SM‘s MAC address. The Username can be up to 128 non-special (no diacritical markings) alphanumeric characters. Enter the desired password for the SM in the Password and Confirm Password fields.. The Password must match the password configured for the SM on the RADIUS server. The default Password is ―password‖. The Password can be up to 128 non-special (no diacritical markings) alphanumeric characters. Handling Certificates Managing SM Certificates via the SM GUI The default public Canopy certificates are loaded into SMs upon factory software installation. The default certificates are not secure and are intended for use during lab and field trials as part of gaining experience with the RADIUS functionalities or as an option during debug. For secure operation, an operator will want to create or procure their own certificates. Up to 2 certificates can be resident on an SM. An installed certificate can be deleted by clicking the Delete button in the certificate‘s description block on the Configuration > Security tab. To restore fhe 2 default certificates, click the Use Default Certificates button in the RADIUS Certificate Settings parameter block and reboot the radio. To upload a certificate manually to an SM, first load it in a known place on your PC or network drive, then click on a Delete button on one of the Certificate description blocks to delete a certificate to provide space for your certificate. Click on Choose File, browse to the location of the certificate, and click the Import Certificate button, and then reboot the radio to use the new certificate. When a certificate is in use, after the SM successfully registers to an AP, an indication of In Use will appear in the description block of the certificate being used. The public certificates installed on the SMs are used with the private certificate on the RADIUS server to provide a public/private key encryption system.

A server private certificate, server key, and CA certificate that complement the public certificates distributed to the SMs, as well as the Canopy dictionary file that defines Vendor Specific Attributes (VSAa). Default certificate files and the dictionary file are available from the software site: www.cambiumnetworks.com/support/pmp/software/ after entering your name, email address, and either Customer Contract Number or the MAC address of a module covered under the 12 month warranty. Optionally, operators may configure the RADIUS server response messages (Accept or Reject) so that the user has information as to why they have been rejected. The AP displays the RADIUS Authentication Reply message strings in the Session Status list as part of each SM‘s information. The SM will show this string (listed as Authentication Response on the SM GUI )on the main Status page in the Subscriber Module Stats section. (Note: Aradial AAA servers only support operator-configurable Authentication Accept responses, not Authentication Reject responses). Figure 31 AP display of RADIUS accept for SM

The associated SM GUI page, tab, and parameter is listed to aid cross-referencing and understanding of the VSAs. A RADIUS dictionary file is available from the software site: www.cambiumnetworks.com/support/pmp/software/ The RADIUS dictionary file defines the VSAs and their values and is usually imported into the RADIUS server as part of server and database setup. Assigning SM management IP addressing via RADIUS Operators may use a RADIUS AAA server to assign management IP addressing to SM modules (framed IP address). SMs now interpret attributes Framed-IP-Address, Framed-IP-Netmask, and Motorola-Canopy-Gateway from RADIUS. The RADIUS dictionary file has been updated to include the Motorola-Canopy-Gateway attribute and is available on the Motorola Software Support website. In order for these attributes to be assigned and used by the SM, the following must be true: The Canopy system is configured for AAA authentication
Task 12: Configuring a RADIUS server Chapter 2: Configuration and alignment 2-130 pmp-0050 (May 2012) The SM is not configured for DHCP on its management interface. If DHCP is enabled and these attributes are configured in the RADIUS server, the attributes will be ignored by the SM. The SM management interface must be configured to be publically accessible. If the SM is configured to have local accessibility, the management interface will still be assigned the framed addressing, and the SM will become publicly accessible via the assigned framed IP addressing. When using these attributes, for the addressing to be implemented by the SM operators must configure Framed-IP-Address in RADIUS. If Framed-IP-Address is not configured but Framed-IP-Netmask and/or Motorola-Canopy-Gateway is configured, the attributes will be ignored. In the case where only the Framed-IP-Address is configured, Framed-IP-Netmask defaults to 255.255.0.0 (NAT disabled) / 255.255.255.0 (NAT enabled) and Motorola-Canopy-Gateway defaults to 0.0.0.0.

No centralized RADIUS accounting (access control) is performed. • Remote: Authentication by the centralized RADIUS server is required to gain access to the SM if the SM is registered to an AP that has RADIUS AAA Authentication Mode selected. For up to 2 minutes a test pattern will be displayed until the server responds or times out. • Remote then Local: Authentication using the centralized RADIUS server is attempted. If the server sends a reject message, then the setting of Allow Local Login after Reject from AAA determines if the local user database is checked or not. If the configured servers do not respond within 2 minutes, then the local user database is used. The successful login method is displayed in the navigation column of the SM. Note, remote access control is enabled only after the SM registers to an AP that has Authentication Mode set to RADIUS AAA. Local access control will always be used before registration and will be used after registration if the AP is not configured for RADIUS.

It will not include broadcast. Acct-Output-Packets Sum of unicast and multicast packets that are sent from a particular SM over the regular data VC and the high priority data VC (if enabled). The data accounting configuration is located on the AP‘s Accounts > User Authentication and Access Tracking GUI menu, and the AP‘s Authentication Mode must be set to Radius AAA for the menu to appear. The accounting may be configured via the AP GUI as shown in the figures below. By default accounting messages are not sent and the operator has the choice of configuring to send only Device Access accounting messages (when a user logs in or out of the radio), only Data Usage messages, or both. When Data Accounting is enabled, the operator must specify the interval of when the data accounting messages are sent (0 – disabled, or in the range of 30-10080 minutes). The default interval is 30 minutes. Table 59 RADIUS accounting messages configuration Table 60 RADIUS data accounting message interval The data accounting message data is based on the SM statistics that the AP maintains, and these statistics may be cleared on the AP by an operator. If an operator clears these messages and data accounting is enabled, an accounting stop message is sent followed by an accounting start message to notify the AAA of the change. If an operator clears the VC statistics on the device through the management GUI, a RADIUS stop message and data start message will be issued for each device affected. The start and stop messages will only be sent once every 5 minutes, so if an operator clears these statistics multiple times within 5 minutes, only one set of data stop/start messages will be sent. This may result in inaccurate data accumulation results.
Task 12: Configuring a RADIUS server Chapter 2: Configuration and alignment 2-138 pmp-0050 (May 2012) RADIUS Device Re-Authentication PMP 450 systems include support for periodic SM re-authentication in a network without requiring the SM to re-register (and drop the session). The re-authentication may be configured to occur in the range of every 30 minutes to weekly. Table 61 Device re-authentication configuration The re-authentication interval is only configurable on the AP. When this feature is enabled, each SM that enters the network will re-authenticate each the interval time has expired without dropping the session. The response that the SM receives from the AAA server upon re-authentication is one of the following: Success: The SM will continue normal operation Reject: The SM will de-register and will attempt network entry again after 1 minute and then if rejected will attempt re-entry every 15 minutes Timeout or other error: The SM will remain in session and attempt 5 times to re-authenticate with the RADIUS-REQUEST message. If these attempts fail, then the SM will go out of session and proceed to re-authenticate after 5 minutes, then every 15 minutes. Although re-authentication is an independent feature, it was designed to work alongside with the RADIUS data usage accounting messages. If a user is over their data usage limit the network operator can reject the user from staying in the network. Operators may configure the RADIUS ‗Reply-Message‘ attribute with an applicable message (i.e. ―Data Usage Limit Reached‖) that will be sent to the subscriber module and displayed on the general page. RADIUS Attribute Framed-IP-Address Operators may now use a RADIUS AAA server to assign management IP addressing to SM modules (framed IP address). SMs now interpret attributes Framed-IP-Address, Framed-IP-Netmask, and Motorola-Canopy-Gateway from RADIUS. The RADIUS dictionary file has been updated to include the Motorola-Canopy-Gateway attribute and is available on the Motorola Software Support website. In order for these attributes to be assigned and used by the SM, the following must be true: The Canopy system is configured for AAA authentication The SM is not configured for DHCP on its management interface. If DHCP is enabled and these attributes are configured in the RADIUS server, the attributes will be ignored by the SM. The SM management interface must be configured to be publically accessible. If the SM is configured to have local accessibility, the management interface will still be assigned the framed addressing, and the SM will become publicly accessible via the assigned framed IP addressing.
PMP 450 Configuration and User Guide Task 12: Configuring a RADIUS server pmp-0050 (May 2012) 2-139 When using these attributes, for the addressing to be implemented by the SM operators must configure Framed-IP-Address in RADIUS. If Framed-IP-Address is not configured but Framed-IP-Netmask and/or Motorola-Canopy-Gateway is configured, the attributes will be ignored. In the case where only the Framed-IP-Address is configured, Framed-IP-Netmask defaults to 255.255.0.0 (NAT disabled) / 255.255.255.0 (NAT enabled) and Motorola-Canopy-Gateway defaults to 0.0.0.0.

Table 64 Exposure Separation Distances Module Type Separation Distance from Persons PMP 450 AP or SM At least 20 cm (approx 8 in) Details of Exposure Separation Distances Calculations and Power Compliance Margins Limits and guidelines for RF exposure come from: US FCC limits for the general population. See the FCC web site at http://www.fcc.gov, and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of Federal Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC OET Bulletin 65. Health Canada limits for the general population. See Safety Code 6 on the Health Canada web site at http://www.hc-sc.gc.ca/. ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the general public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields. The applicable power density exposure limits from the documents referenced above are 10 W/m2 for RF energy in the 5.7-GHz frequency band. Peak power density in the far field of a radio frequency point source is calculated as follows: SP G4d2 where S = power density in W/m2 P = RMS transmit power capability of the radio, in W G = total Tx gain as a factor, converted from dB d = distance from point source, in m Rearranging terms to solve for distance yields dP G4S Table 65 shows calculated minimum separation distances d, recommended distances and resulting power compliance margins for each frequency band and antenna combination.

They are also chosen so that an OFDM module has the same exposure distance as a Canopy module, to simplify communicating and heeding exposure distances in the field. These are conservative distances: They are along the beam direction (the direction of greatest energy). Exposure to the sides and back of the module will be significantly less. They meet sustained exposure limits for the general population (not just short term occupational exposure limits), with considerable margin. The calculated compliance distance d is overestimated because the far-field equation models the antenna as a point source and neglects the physical dimension of the antenna.
