The BHS GUI opens to the General Status tab of its Home page. An example of the BHS General Status tab is displayed in Figure 65. Figure 65: General Status tab of BHS, example The General Status tab provides information on the operation of this BHS. This is the tab that opens by default when you access the GUI of the BHS. The General Status tab provides the following read-only fields. Device Type This field indicates the type of the Canopy module. Values include the frequency band of the BHS, its module type, and its MAC address. Software Version This field indicates the Canopy system release, the time and date of the release, the modulation rate, and whether communications involving the module are secured by DES or AES encryption (see Encrypting Canopy Radio Transmissions on Page 369). If you request technical support, provide the information from this field.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 211 Software BOOT Version This field indicates the version of the CANOPYBOOT file. If you request technical support, provide the information from this field. Board Type This field indicates the series of hardware. See Designations for Hardware in Radios on Page 365. FPGA Version This field indicates the version of the field-programmable gate array (FPGA) on the module. When you request technical support, provide the information from this field. Uptime This field indicates how long the module has operated since power was applied. System Time This field provides the current time. When a BHS registers to a BHM, it inherits the system time, which is displayed in this field as GMT (Greenwich Mean Time). Ethernet Interface This field indicates the speed and duplex state of the Ethernet interface to the BHS. Session Status This field displays the following information about the current session: ◦ Scanning indicates that this SM currently cycles through the RF frequencies that are selected in the Radio tab of the Configuration page. ◦ Syncing indicates that this SM currently attempts to receive sync. ◦ Registering indicates that this SM has sent a registration request message to the AP and has not yet received a response. ◦ Registered indicates that this SM is both − registered to an AP. − ready to transmit and receive data packets. ◦ Alignment indicates that this SM is in an aiming mode. See Table 41 on Page 179. Registered AP This field displays the MAC address of the BHM to which this BHS is registered. RSSI, Power Level, and Jitter The General Status tab shows the received Power Level in dBm and Jitter. Proper alignment maximizes Power Level and minimizes Jitter. As you refine alignment, you should favor lower jitter over higher dBm. For example, if coarse alignment gives the BHS a power level of −75 dBm and a jitter measurement of 5, and further refining the alignment drops the power level to −78 dBm and the jitter to 2 or 3, use the refined alignment, with the following caveats: ◦ When the receiving link is operating at 1X, the Jitter scale is 0 to 15 with desired jitter between 0 and 4.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 212 ◦ When the receiving link is operating at 2X, the Jitter scale is 0 to 15 with desired jitter between 0 and 9. For historical relevance, the General Status tab also shows the RSSI, the unitless measure of power. Use Power Level and ignore RSSI. RSSI implies more accuracy and precision than is inherent in its measurement. NOTE: Unless the page is set to auto-refresh, the values displayed are from the instant the General Status tab was selected. To keep a current view of the values, refresh the browser screen or set to auto-refresh. Air Delay This field displays the distance in feet between the BHS and the BHM. To derive the distance in meters, multiply the value of this parameter by 0.3048. Distances reported as less than 200 feet (61 meters) are unreliable. Site Name This field indicates the name of the physical module. You can assign or change this name in the SNMP tab of the BHS Configuration page. This information is also set into the sysName SNMP MIB-II object and can be polled by an SNMP management server. Site Contact This field indicates contact information for the physical module.

The range of selections are defined in Table 42. Table 42: Port Configuration selections for CMMmicro Selection Result Auto The port attempts to auto-negotiate speed and duplex state. (This is the default and recommended setting.) 100FDX The port is forced to 100 Mbps and full duplex. 100HDX The port is forced to 100 Mbps and half duplex. 10FDX The port is forced to 10 Mbps and full duplex. 10HDX The port is forced to 10 Mbps and half duplex. If you change this value for a port and then click Save Changes, then the change becomes effective immediately and the previous value is lost. Description You can enter text in this parameter (for example, text that helps you to associate the port number with the connected device.) If you change this value for a port and then click Save Changes, then the change becomes effective immediately and the previous value is lost. Power Port Control Ensure that power is off for every port that connects to a router, computer, or other network equipment. Turn on 24-V DC power for ports that connect to Canopy APs or BHs.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 227 CAUTION! Never connect any devices other than Canopy APs and BHs to a powered port. Powered ports are indicated by a red LED to the right of the port. (See Item 7 in Figure 69 on Page 219.) A powered port has 24-V DC on Pins 7 and 8 and 24-V return on Pins 4 and 5. This can damage other networking equipment, such as a computer or a router. If you change this value for a port and then click Save Changes, then the change becomes effective immediately and the previous value is lost. Display-Only Access To set this password, enter the same expression in both Display-Only Access fields for verification. When the web-based interface prompts for this password, no user name is required. However, when a telnet or FTP session prompts for this password, you must enter the user name root in addition to the password. If you set and then forget the Display-Only Access password, then you must both 1. physically access the module. 2. use the CMMmicro override toggle switch to electronically access the module configuration parameters at 169.254.1.1. See Overriding Forgotten IP Addresses or Passwords on CMMmicro on Page 375. Full Access If you set the Full Access password, this password will allow ◦ telnet and FTP access to the module. ◦ viewing or changing the parameters of the module. To set this password, enter the same expression in both Full Access fields for verification. When the web-based interface prompts for this password, no user name is required. However, when a telnet or FTP session prompts for this password, you must enter the user name root in addition to the password. If you set and then forget the Full Access password, then you must both 1. physically access the module. 2. use the CMMmicro override toggle switch to electronically access the module configuration parameters at 169.254.1.1. See Overriding Forgotten IP Addresses or Passwords on CMMmicro on Page 375. NOTE: You can unset either password (revert the access to no password required). To do so, type a space into the field and reboot the module. You must enter any password twice to allow the system to verify that the password is not mistyped. After any password is set and a reboot of the module has occurred, a Password Set indicator appears to the right of the field.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 228 RECOMMENDATION: Note the passwords that you enter. Ensure that you can readily associate these passwords both with the module and with the other data that you store about the module. 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. If you change this value and then click Save Changes, then the change becomes effective immediately and the previous value is lost. SNMP Community String Specify a control string that allows an Network Management Station (NMS) to access SNMP information. No spaces are allowed in this string. The default string is Canopy. The SNMP Community String value is clear text and is readable by a packet monitor. Additional security derives from the configuration of the SNMP Accessing Subnet, Trap Address, and Permission parameters. SNMP Accessing Subnet Specify the addresses that are allowed to send SNMP requests to this CMMmicro. The NMS has an address that is among these addresses (this subnet). You must enter both ◦ The network IP address in the form xxx.xxx.xxx.xxx ◦ The CIDR (Classless Interdomain Routing) prefix length in the form /xx For example ◦ the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits in the address range are identical among all members of the subnet). ◦ 192.168.102.0 specifies that any device whose IP address is in the range 192.168.102.0 to 192.168.102.254 can send SNMP requests to the CMMmicro, presuming that the device supplies the correct SNMP Community String value. RECOMMENDATION: For more information on CIDR, execute an Internet search on “Classless Interdomain Routing.” The default treatment is to allow all networks access.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 229 Trap Address Specify the IP address (xxx.xxx.xxx.xxx) of one to ten servers (Prizm or NMS) to which trap information should be sent. Trap information informs the monitoring systems that something has occurred. For example, trap information is sent ◦ after a reboot of the module. ◦ when Prizm or an NMS attempts to access agent information but either − supplied an inappropriate community string or SNMP version number. − is associated with a subnet to which access is disallowed. Permission Select Read Only if you wish to disallow any parameter changes by Prizm or an NMS. Site Name Specify a string to associate with the physical module. This parameter is written into the sysName SNMP MIB-II object and can be polled by an NMS. The buffer size for this field is 128 characters. Site Contact Enter contact information for the module administrator. This parameter is written into the sysContact SNMP MIB-II object and can be polled by an NMS. The buffer size for this field is 128 characters. Site Location Enter information about the physical location of the module. This parameter is written into the sysLocation SNMP MIB-II object and can be polled by an NMS. The buffer size for this field is 128 characters. The CMMmicro Configuration page also provides the following buttons. Enable 802.1Q Tagging Once 802.1Q Tagging is enabled and an 802.1Q VLAN ID is set, only frames that are VLAN tagged with the configured tag value will be accepted by the management controller of the CMMmicro. All frames outgoing from the management controller of the CMMmicro will have an 802.1Q VLAN tag, set to the configured VLAN ID. 802.1Q VLAN ID Once 802.1Q Tagging is enabled and an 802.1Q VLAN ID is set, only frames that are VLAN tagged with the configured tag value will be accepted by the management controller of the CMMmicro. All frames outgoing from the management controller of the CMMmicro will have an 802.1Q VLAN tag, set to the configured VLAN ID. VLAN Port Configuration Each column in the VLAN Port Configuration section of Figure 72 corresponds to a port. Checkboxes in each column control which ports can transmit traffic that arrives on the (column) port. For example, in the first column if only Port 2 is checked, then Port 1 (column 1) will only be allowed to send data out on Port 2 (checked box). Port 2 (second column) is able to send data out on all other ports. All other ports, meanwhile, are only allowed to send data out on Port 2. This configuration is also known as an Uplink configuration for Port 2. Each direction (for example, port 1 to port 2 versus port 2 to port 1) must be configured separately. It is possible to configure a port to send data to a second port, but not allow
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 230 the second port to send data back to the first port (for example, check Port 8 in the Port 2 column, but do not check Port 2 in the Port 8 column). These settings should be changed with caution, and with two-way communication in mind. In all cases, even when not checked, all ports will still be able to communicate with the CMMmicro management controller. Setting (checking) any Uplink Port checkboxes (see Figure 72) will override VLAN Port Configuration settings. If you desire complete control on a port-by-port basis using VLAN Port Configuration, all Uplink Port boxes must be unchecked in the Uplink Port section. Save Changes, Undo Saved Changes, Set to Defaults, Reboot The effects of clicking these buttons are defined in Table 43. Table 43: When changes become effective in CMMmicro For these parameters… clicking this button… has this effect. Save Changes Any change becomes effective immediately and any previous setting is lost. Undo Saved Changes No change is undone, and no previous setting is restored. Set to Defaults The default setting is not restored. Port Configuration Description Power Port Control Webpage Auto Update Reboot No change that is not already effective becomes effective. Save Changes Any change is recorded into flash memory but does not become effective immediately, and any previous setting can be restored. Undo Saved Changes Any change recorded into flash memory is undone, and the previous setting is restored. Set to Defaults The default setting is restored. Any other parameter Reboot Any change recorded in flash memory (and not later undone) becomes effective. In addition, when you click Reboot, the following events occur and are logged: ◦ The CMMmicro reboots. ◦ Any AP or BH that receives power from the CMMmicro loses power and thus also reboots. ◦ Any AP or BH that does not receive power but receives sync from the CMMmicro loses and then regains sync.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 231 16.5.4 Configuring Modules for Connection to CMMmicro After configuring the CMMmicro, configure the APs and BHs as follows. In each AP or BH that connects to a CMMmicro, you must set the Sync Input parameter of the Configuration page of that module to Sync to Received Signal (Power Port). See ◦ Sync Input on Page 237. ◦ Sync Input on Page 296. 16.5.5 Event Log Page of the CMMmicro This page may contain information that can be useful under the guidance of Canopy technical support. For this reason, the operator should not clear the contents of this page before contacting technical support. 16.5.6 GPS Status Page of the CMMmicro An example of the CMMmicro GPS Status page is displayed in Figure 73. Figure 73: GPS Status page of CMMmicro, example The GPS Status page provides information from the GPS antenna and information about the GPS receiver in the CMMmicro. Antenna Connection This field displays the status of the signal from the antenna as follows: ◦ OK indicates that the GPS interface board is detecting an incoming signal on the coaxial cable from the GPS antenna.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 232 ◦ No Antenna indicates the GPS interface board is not detecting any incoming signal. The other GPS Status fields are described under Satellites Visible on Page 222. GPS Receiver Information This field displays information about the GPS interface board. 16.5.7 Port MIB Page of the CMMmicro An example of the Port MIB (Ethernet statistics) web page is displayed in Figure 74. Figure 74: Port MIB page of CMMmicro, example The Port MIB page displays Ethernet statistics and traffic information for the ports on the managed switch. To display the port statistics, click on a port number. Ports 1 through 8 are the regular ports, connected to APs, BHs, or other network elements. Port 9 is the connection between the managed switch and the CMMmicro processor. Thus, updates to interface pages, SNMP activities, and FTP and telnet sessions create traffic on Port 9. These Ethernet statistics can also be retrieved from the CMMmicro by a Network Management Station using SNMP. During advanced troubleshooting, this information can be useful as you see the activity on a single port or as you compare activity between ports of the CMMmicro.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 233 17 PREPARING COMPONENTS FOR DEPLOYMENT Your test of the modules not only verified that they are functional, but also yielded data that you have stored about them. Most efficiently preparing modules for deployment involves ◦ retrieving that data. ◦ systematically collecting the data into a single repository, while keeping a strong (quick) association between the data and the module. ◦ immediately merging module access data into this previously stored data. 17.1 CORRELATING COMPONENT-SPECIFIC INFORMATION You can use the data that you noted or printed from the Status pages of the modules to ◦ store modules for future deployment. ◦ know, at a glance, how well-stocked you are for upcoming network expansions. ◦ efficiently draw modules from stock for deployment. ◦ plan any software updates that you − wish to perform to acquire features. − need to perform to have the feature set be consistent among all modules in a network expansion. You can make these tasks even easier by collecting this data into a sortable database. 17.2 ENSURING CONTINUING ACCESS TO THE MODULES As you proceed through the steps under Configuring for the Destination on Page 235, you will set values for parameters that specify the sync source, data handling characteristics, security measures, management authorities, and other variables for the modules. While setting these, you will also tighten access to the module, specifically in ◦ the Color Code parameter of Configuration page ◦ the Display-Only Access and Full Access password parameters of the Configuration page. ◦ the addressing parameters of the IP Configuration page. Before you set these, consider whether and how you may want to set these by a self-devised scheme. A password scheme can help you when you have forgotten or misfiled a password. An IP addressing scheme may be essential to the operation of your network and to future expansions of your network. As you set these, note the color code and note or print the parameters you set on the Configuration page tabs. Immediately associate them with the following previously stored data about the modules: ◦ device type, frequency band, and MAC address ◦ software version and encryption type ◦ software boot version ◦ FPGA version
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 235 18 CONFIGURING FOR THE DESTINATION 18.1 CONFIGURING AN AP FOR THE DESTINATION If an ADMINISTRATOR-level password has been set in the AP, you must log into the module before you can configure its parameters. See Managing Module Access by Passwords on Page 371. 18.1.1 General Tab of the AP An example of an AP General tab is displayed in Figure 75.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 236 Figure 75: General tab of AP, example The General tab of the AP contains many of the configurable parameters that define how the AP and the SMs in the sector operate. As shown in Figure 75, you may set the Configuration page parameters as follows.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 237 Device Setting You can temporarily transform an AP into an SM and thereby use the spectrum analyzer functionality. See Using the AP as a Spectrum Analyzer on Page 364. Otherwise, the selection for this parameter is AP. Link Speeds Specify 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, BHs, and SMs in the operator network. Configuration Source See Setting the Configuration Source on Page 292. CAUTION! Do not set this parameter to BAM where both ◦ a BAM release earlier than 2.1 is implemented. ◦ the All Local SM Management parameter (in the VLAN Configuration page of the AP) is set to Enable. 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. 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. ◦ Select Sync to Received Signal (Timing Port) to set this AP to receive sync from a connected CMM2, an AP in the cluster, an SM, or a BH timing slave. ◦ Select Generate Sync Signal where the AP does not receive sync, and no other AP or BHM is active within the link range. 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.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 238 CAUTION! 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. For a full description of them, see Uplink Frame Contents on Page 81. 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. See Uplink Frame Contents on Page 81 and Address Resolution Protocol on Page 162. 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 See 2X Operation on Page 89. 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. See AP-SM Links on Page 99. The General tab also provides the following buttons.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 239 Save Changes When you click this button, any changes that you made on the this tab are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented. 18.1.2 IP Tab of the AP An example of the IP tab of the AP is displayed in Figure 76. Figure 76: IP tab of AP, example
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 240 You may set the IP tab parameters as follows. LAN1 Network Interface Configuration, IP Address Enter the non-routable IP address to associate with the Ethernet connection on this AP. (The default IP address from the factory is 169.254.1.1.) If you set and then forget this parameter, then you must both 1. physically access the module. 2. 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, SM, or BH on Page 375. RECOMMENDATION: 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, Subnet Mask Enter an appropriate subnet mask for the AP to communicate on the network. The default subnet mask is 255.255.0.0. See Allocating Subnets on Page 162. LAN1 Network Interface Configuration, Gateway IP Address Enter the appropriate gateway for the AP to communicate with the network. The default gateway is 169.254.0.0. The values of these four LAN1 network interface configuration parameters are displayed read only along with the Ethernet speed and duplex state on the Network Interface tab of the Home page in the AP. 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. LAN2 Network Interface Configuration (RF Private Interface), IP Address You should 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
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 241 NOTE: Where space is limited for subnet allocation, be advised that an SM need not have an operator-assigned IP address. The SM is directly accessible without an LUID if either the SM Color Code parameter is set to 0 or the AP has a direct Ethernet connection to the SM. The IP Configuration page also provides the following buttons. Save Changes When you click this button, any changes that you made on this tab are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented. 18.1.3 Radio Tab of the AP An example of the Radio tab of the AP is shown in Figure 77. Figure 77: Radio tab of AP (900 MHz), example
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 242 The Radio tab of the AP contains some of the configurable parameters that define how the AP operates. As shown in Figure 77, you may set the Radio tab parameters as follows. Radio Frequency Carrier Specify the frequency for the module to transmit. The default for this parameter is None. (The selection labeled Factory requires a special software key file for implementation.) For a list of channels in the band, see the drop-down list or Considering Frequency Band Alternatives on Page 136. 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. On all Canopy modules, the default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). RECOMMENDATION: Note the color code that you enter. Ensure that you can readily associate this color code both with the module and with the other data that you store about the module. 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: ◦ Assign a unique Sector ID to each sector in an AP cluster. ◦ Repeat the assignment pattern throughout the entire Canopy system. 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. See Table 24 on Page 100. 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 APs in the non 900-MHz frequency band ranges, although the typical maximum range where an SM is deployed with a reflector is 15 miles (24 km), you can set this parameter to as far as 30 miles (48 km). Without increasing the power or sensitivity of the
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 243 AP or SM, the greater value allows you to attempt greater distance where the RF environment and Fresnel zone6 are especially clear. 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. NOTE: In a cluster where at least one AP has Scheduling set to Software and at least one to Hardware, you must use the Frame Calculator web page to coordinate the transmit and receive times and you may further need to adjust the value of the Max Range parameter for individual APs in the cluster to avoid self interference. See Using the Frame Calculator Tool (All) on Page 438. 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%. CAUTION! You must set this parameter exactly the same for all APs in a cluster. Control Slots The recommended number of control slots is as stated in Table 44. Table 44: Control slot settings for all APs in cluster Number of SMs that Register to the AP Number of Control Slots Recommended 1 to 10 0 11 to 50 1 51 to 150 2 151 to 200 3 Slots reserved for control are used for only SM service requests. For data, the hardware scheduler uses unreserved slots first, then any unused slots are available with any reserved slots to the SMs for service requests. 6 See Noting Possible Obstructions in the Fresnel Zone on Page 132.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 244 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. External Filters Delay This parameter is present in only 900-MHz modules and can have effect in only those that have interference mitigation filter(s). Leave this value set to 0, regardless of whether the AP has an interference mitigation filter. Transmit Frame Spreading Where multiple AP clusters operate in the same frequency band range and same geographical area, select Enable. Then SMs between two APs can register in the assigned AP (do not register in another AP). Where multiple AP clusters do not operate in the same frequency band range and same geographical area, select Disable, but observe the following caveat. IMPORTANT! SM throughput is 10% greater with this feature disabled. However, if you disable Transmit Frame Spreading where this feature was previously enabled, monitor the zone for interference over a period of days to ensure that this action has not made any SMs sensitive to the wrong beacon. With this selection enabled, the AP does not transmit a beacon in each frame, but rather transmits a beacon in only pseudo-random frames in which the SM expects the beacon. This allows multiple APs to send beacons to multiple SMs in the same range without interference. Transmitter Output Power Nations and regions may regulate transmitter output power. For example ◦ Both 900-MHz and 5.7-GHz modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance. In addition to setting the power in the 5.7-GHz connectorized module, the operator must set the antenna gain/cable loss such that the module can accurately report received power at the antenna. ◦ Legal maximum allowable transmitter output power and EIRP (Equivalent Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and region. The output power of Series P9 2.4-GHz modules can be adjusted to meet these national or regional regulatory requirements. ◦ Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT member states, for example), generally require equipment using the band to have adjustable power. The professional installer of Canopy 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.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 245 ◦ confirm that the power setting is compliant following any reset of the module to factory defaults. For information on how to calculate the permissible transmitter output power to enter in this parameter, see Adjusting Transmitter Output Power on Page 326. The Radio tab also provides the following buttons. Save Changes When you click this button, any changes that you made on this tab are recorded in flash memory. However, these changes do not apply until the next reboot of the module. Reboot When you click this button 1. the module reboots. 2. any changes that you saved by a click of the Save Changes button are implemented.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 246 18.1.4 SNMP Tab of the AP An example of the SNMP tab of the AP is displayed in Figure 78. Figure 78: SNMP tab of AP, example
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 247 You may set the SNMP tab parameters as follows. Community String Specify a control string that allows an Network Management Station (NMS) to access SNMP information. No spaces are allowed in this string. The default string is Canopy. The Community String value is clear text and is readable by a packet monitor. Additional security derives from the configuration of the Accessing Subnet, Trap Address, and Permission parameters. Accessing Subnet Specify the addresses that are allowed to send SNMP requests to this AP. The NMS has an address that is among these addresses (this subnet). You must enter both ◦ The network IP address in the form xxx.xxx.xxx.xxx ◦ The CIDR (Classless Interdomain Routing) prefix length in the form /xx For example ◦ the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits in the address range are identical among all members of the subnet). ◦ 192.168.102.0 specifies that any device whose IP address is in the range 192.168.102.0 to 192.168.102.254 can send SNMP requests to the AP, presuming that the device supplies the correct Community String value. The default treatment is to allow all networks access. For more information on CIDR, execute an Internet search on “Classless Interdomain Routing.” Trap Address 1 to 10 Specify ten or fewer IP addresses (xxx.xxx.xxx.xxx) to which SNMP traps should be sent. Traps inform Prizm or an NMS that something has occurred. For example, trap information is sent ◦ after a reboot of the module. ◦ when an NMS attempts to access agent information but either − supplied an inappropriate community string or SNMP version number. − is associated with a subnet to which access is disallowed. Trap Enable, Sync Status If you want sync status traps (sync lost and sync regained) sent to Prizm or an NMS, select Enabled. If you want these traps suppressed, select Disabled. Trap Enable, Session Status If you want session status traps sent to Prizm or an NMS, select Enabled. For the names and descriptions of session status traps, see Traps Provided in the Canopy Enterprise MIB on Page 404. If you want these traps suppressed, select Disabled. Read Permissions Select Read Only if you wish to disallow any parameter changes through SNMP (for example, from Prizm or an NMS).
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 248 Site Name Specify a string to associate with the physical module. This parameter is written into the sysName SNMP MIB-II object and can be polled by PrizmEMS or an NMS. The buffer size for this field is 128 characters. Site Contact Enter contact information for the module administrator. This parameter is written into the sysContact SNMP MIB-II object and can be polled by PrizmEMS or an NMS.

Figure 84: Unit Settings tab of AP, example 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. 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, SM, or BH on Page 373. The Unit Settings tab also contains the following buttons.

Figure 85: General tab of SM, example In the General tab of the SM, you may set the following parameters. Link Speeds Specify 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, BHs, and SMs in the operator network.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 261 802.3 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. 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. 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. CAUTION! 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 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. Unlike in previous releases, this is the default selection in Release 8. 2X Rate Disable this parameter to facilitate initial aiming from the destination. Then see 2X Operation on Page 89.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 262 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. See Wiring to Extend Network Sync on Page 367. The General tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory. However, these changes do not apply until the next reboot of the module.

An example of the IP tab in an SM with NAT enabled is displayed in Figure 89. 18.2.4 Radio Tab of the SM An example of the Radio tab in the SM is displayed in Figure 90. Figure 90: Radio tab of SM, example In the Radio tab of the SM, you may set the following parameters. 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.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 274 IMPORTANT! In the 2.4-GHz frequency band, the SM can register to an AP that transmits on a frequency 2.5 MHz higher than the frequency that the SM receiver locks when the scan terminates as successful. This establishes a poor-quality link. To prevent this, select frequencies that are at least 5 MHz apart. In a 2.4-GHz SM, this parameter displays all available channels, but has only three recommended channels selected by default. See 2.4-GHz AP Cluster Recommended Channels on Page 137. In a 5.2- or 5.4-GHz SM, this parameter displays only ISM frequencies. 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. Since the frequencies that this parameter offers for each of these two bands are 5 MHz apart, a scan of all channels does not risk establishment of a poor-quality link as in the 2.4-GHz band. A list of channels in the band is provided in Considering Frequency Band Alternatives on Page 136. (The selection labeled Factory requires a special software key file for implementation.) Color Code 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. On all Canopy modules, the default setting for the color code value is 0. This value matches only the color code of 0 (not all 255 color codes). RECOMMENDATION: Note the color code that you enter. Ensure that you can readily associate this color code both with the module and with the other data that you store about the module. External Filters Delay This parameter is present in only 900-MHz modules and can have effect in only those that have interference mitigation filter(s). If this value is present, leave it set to 0, regardless of whether the SM has an interference mitigation filter.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 275 Transmitter Output Power Nations and regions may regulate transmitter output power. For example ◦ Both 900-MHz and 5.7-GHz modules are available as connectorized radios, which require the operator to adjust power to ensure regulatory compliance. In addition to setting the power in the 5.7-GHz connectorized module, the operator must set the antenna gain/cable loss such that the module can accurately report received power at the antenna. ◦ Legal maximum allowable transmitter output power and EIRP (Equivalent Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and region. The output power of Series P9 2.4-GHz modules can be adjusted to meet these national or regional regulatory requirements. ◦ Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT member states, for example), generally require equipment using the band to have adjustable power. The professional installer of Canopy 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. For information on how to calculate the permissible transmitter output power to enter in this parameter, see Adjusting Transmitter Output Power on Page 326. The Radio tab also contains the following buttons. Save Changes When you click this button, any changes that you made on all tabs are recorded in flash memory.

Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 276 18.2.5 SNMP Tab of the SM An example of the SNMP tab in an SM is displayed in Figure 91. Figure 91: SNMP tab of SM, example In the SNMP tab of the SM, you may set the following parameters. Community String Specify a control string that allows Prizm or an NMS (Network Management Station) to access MIB information about this SM. No spaces are allowed in this string. The default string is Canopy.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 277 The Community String value is clear text and is readable by a packet monitor. Additional security derives from the configuration of the Accessing Subnet, Trap Address, and Permission parameters. Accessing Subnet Specify the addresses that are allowed to send SNMP requests to this SM. Prizm or the NMS has an address that is among these addresses (this subnet). You must enter both ◦ The network IP address in the form xxx.xxx.xxx.xxx ◦ The CIDR (Classless Interdomain Routing) prefix length in the form /xx For example ◦ the /16 in 198.32.0.0/16 specifies a subnet mask of 255.255.0.0 (the first 16 bits in the address range are identical among all members of the subnet). ◦ 192.168.102.0 specifies that any device whose IP address is in the range 192.168.102.0 to 192.168.102.254 can send SNMP requests to the SM, presuming that the device supplies the correct Community String value. The default treatment is to allow all networks access (set to 0). For more information on CIDR, execute an Internet search on “Classless Interdomain Routing.” RECOMMENDATION: The subscriber can access the SM by changing the subscriber device to the accessing subnet. This hazard exists because the Community String and Accessing Subnet are both visible parameters. To avoid this hazard, configure the SM to filter (block) SNMP requests. See Filtering Protocols and Ports on Page 376. Trap Address 1 to 10 Specify ten or fewer IP addresses (xxx.xxx.xxx.xxx) to which trap information should be sent. Trap information informs Prizm or an NMS that something has occurred. For example, trap information is sent ◦ after a reboot of the module. ◦ when Prizm or an NMS attempts to access agent information but either − supplied an inappropriate community string or SNMP version number. − is associated with a subnet to which access is disallowed. Read Permissions Select Read Only if you wish to disallow Prizm or NMS SNMP access to configurable parameters and read-only fields of the SM. Site Name Specify a string to associate with the physical module. This parameter is written into the sysName SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this field is 128 characters.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 278 Site Contact Enter contact information for the module administrator. This parameter is written into the sysContact SNMP MIB-II object and can be polled by Prizm or an NMS. The buffer size for this field is 128 characters. Site Location Enter information about the physical location of the module. This parameter is written into the sysLocation SNMP MIB-II object and can be polled by Prizm or an NMS.

Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 283 In the Security tab of the SM, you may set the following parameters. Authentication Key Only if the AP to which this SM will register requires authentication, specify the key that the SM should use when authenticating. 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. See Authentication Manager Capability on Page 383. 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. NOTE: 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, Canopy recommends that you enter 32 characters to achieve the maximal security from this feature. Web, Telnet, FTP Session Timeout Enter the expiry in seconds for remote management sessions via HTTP, telnet, or ftp access to the SM. Ethernet Access Control If you want to prevent any device that is connected to the Ethernet port of the SM from accessing the management interface of the SM, select Ethernet Access Disabled. 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. NOTE: 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). 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.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 284 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 SM 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. The Security tab of the SM also provides the following buttons. Save Changes When you click this button, any changes that you made on this tab are recorded in flash memory.

Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 288 In the DiffServe tab of the SM, you may set the following parameters. CodePoint 1 through CodePoint 47 CodePoint 49 through CodePoint 55 CodePoint 57 through CodePoint 63 The default priority value for each settable CodePoint is shown in Figure 113. Priorities of 0 through 3 map to the low-priority channel; 4 through 7 to the high-priority channel. The mappings are the same as 802.1p VLAN priorities. Consistent with RFC 2474 ◦ CodePoint 0 is predefined to a fixed priority value of 0 (low-priority channel). ◦ CodePoint 48 is predefined to a fixed priority value of 6 (high-priority channel). ◦ CodePoint 56 is predefined to a fixed priority value of 7 (high-priority channel). You cannot change any of these three fixed priority values. Among the settable parameters, the priority values (and therefore the handling of packets in the high- or low-priority channel) are set in the AP for all downlinks within the sector and in the SM for each uplink.

Figure 99: Unit Settings tab of SM, example The Unit Settings tab of the SM contains an option for how the SM should react when it detects a connected override plug. You may set this option as follows. 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.

Where BAM, then SM is the indication, parameters for which BAM does not send values are obtained from the SM. This is the case where the BAM server is operating on a BAM release that did not support the feature. This is also the case where the feature enable/disable flag in BAM is set to disabled. The values are those previously set or, if none ever were, then the default values. Where BAM is the indication, values in the SM are disregarded. Where SM is the indication, values that BAM sends for the SM are disregarded. The high-priority channel is unavailable to Series P7 and P8 SMs that run Canopy Release 8. For any SM whose Authentication Mode parameter is not set to Authentication Required, the listed settings are derived as shown in Table 47.
Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 294 Table 47: Where feature values are obtained for an SM with authentication disabled Values are obtained from Configuration Source Setting in the AP MIR Values VLAN Values High Priority Channel State CIR Values BAM AP AP AP AP SM SM SM SM SM BAM+SM SM SM SM SM BAM Release 2.0 sends only MIR values. BAM Release 2.1 and Prizm Release 2.0 and 2.1 send VLAN and high-priority channel values as well. For the case where the Configuration Source parameter in the AP is set to BAM, 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: − either Enable or Disable as the value of the Dynamic Learning parameter. − Allow Learning : No under Active Configuration. For the case where the Configuration Source parameter in the AP is set to BAM+SM, and Prizm does not send VLAN values, the SM ◦ uses the configured value in the SM for Dynamic Learning. 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. This selection (BAM+SM) is not recommended where Prizm manages the VLAN feature in SMs. 18.4 CONFIGURING A BH TIMING MASTER FOR THE DESTINATION NOTE: The PTP 400 and PTP 600 series bridges (previously known as 30/60 Mbps and 150/300 Mbps Backhauls) are described in their own dedicated user guides.

Release 8 Installation and Configuration Guide Issue 2, November 2007 Draft 5 for Regulatory Review 296 In the General tab of the BHM, you may set the following parameters. Timing Mode Select Timing Master. This BH will provide sync for the link. Whenever you toggle this parameter to Timing Master from Timing Slave, you should also do the following: 1. Make no other changes in this or any other interface page. 2. Save this change of timing mode. 3. Reboot the BH. RESULT: The set of interface web pages that is unique to a BHM is made available. Link Speeds Specify 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, BHs, and SMs in the operator network. Sync Input Specify the type of synchronization for this BH timing master to use. ◦ Select Sync to Received Signal (Power Port) to set this BHM to receive sync from a connected CMMmicro. ◦ Select Sync to Received Signal (Timing Port) to set this BHM to receive sync from a connected CMM2, an AP in the cluster, an SM, or a BH timing slave. ◦ Select Generate Sync Signal where the BHM does not receive sync, and no AP or other BHM is active within the link range. 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. CAUTION! An inappropriately low Bridge Entry Timeout setting may lead to temporary loss of communication with some end users. Bridging Functionality Select whether you want bridge table filtering active (Enable) or not (Disable) on this BHM. Selecting Disable allows you to use redundant BHs without causing network addressing problems. Through a spanning tree protocol, this reduces the convergence time from 25 minutes to mere seconds. However, you should disable bridge table filtering as only a deliberate part of your overall network design. Otherwise, disabling it allows unwanted traffic across the wireless interface.
