Access / One® NetworkManaging the Network 755SNMPThis command allows you to define the SNMP Communities, the SNMP System, andany specific SNMP Trap Managers. With SNMP enabled and the settings on thispage defined, your Access/One Network will support most common SNMPmanagement consoles.The system also supports Syslog (System Logging) via an SNMP manager (in parallelwith basic Syslog services) where Syslog text information is encoded in an SNMPtrap message and presented to the operator.SNMP (Simple Network Management Protocol is a standard protocol that regulatesnetwork management over the Internet. SNMP uses TCP/IP to communicate with amanagement platform, and offers a standard set of commands that make multi-vendor operability possible. SNMP uses a standard set of definitions, known as aMIB (Management Information Base), which can be supplemented with Enterprise-specific extensions. Strix provides its own proprietary MIBs. For more informationabout Strix MIBs, contact Strix technical support.Figure 57. Configuring Access/One Network for SNMP

When this mode is enabled, only addresses assigned here willbe trusted by the network for management at any network module.Figure 59. Assigning Trusted IP AddressesThe following options are available with this command:◗Trusted ModeYou can only enable this option if you have added at least one trusted IPaddress. Once a trusted IP has been added, check this box to enable thetrusted mode (or uncheck the box if you want to disable this feature).◗IP AddressYou must add at least one IP address if you want to enable the trusted modefeature. To add an address, simply enter a valid IP address in this field thenclick on the Add button (the new address is listed below this field). You canadd as many trusted IP addresses as you want. To delete an address, click onthe X icon alongside the address, then confirm your request at the pop-updialog. However, if you have only one trusted IP address listed, you cannotdelete the address if the trusted mode is enabled—you must disable thetrusted mode before attempting to delete a sole trusted IP address.After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network. If necessary, you can click on the factory default (FD) button in thetoolbar to reset all data on this page to its factory default state.
Access / One® Network78 Managing the Network5TCP/IP SettingsThis command allows you to specify whether Access/One will obtain the DefaultGateway and DNS IP addresses automatically, or use pre-configured static IPaddresses.Figure 60. TCP/IP SettingsThe following options are available with this command:◗Default GatewayThe system is set up to use DHCP (Dynamic Host Configuration Protocol) toobtain the default gateway IP address automatically (default).When using wireless uplinks between nodes, Access/OneNetwork’s self-tuning feature requires that a default gateway and/or DNS is specified to determine delays to the host Ethernet.When DHCP is used across the network (default), specifyingboth of these will satisfy this requirement.
Access / One® NetworkManaging the Network 795◗DNS ServerChoose whether you want the system to use DHCP to obtain the DNS IPaddress automatically (default), or use a pre-configured static IP address. Ifyou choose the latter option, enter IP addresses for the primary andsecondary (if any) DNS server. DNS is used by your Access/One Networkmodules to lookup the names of various servers (for example, the RADIUSand FTP servers). You must specify a Domain Name when static IP addressesare used. This has the effect of appending the Domain Name to non-fullyqualified address requests (for example, the FTP server host name configuredas FTP123 will become FTP123.yourdomain.com).After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network. If necessary, you can click on the factory default (FD) button in thetoolbar to reset all data on this page to its factory default state.Network TopologyThis command allows you to define whether your Access/One Network will obtainits Master Network Server IP address automatically or use a pre-configured static IPaddress. It also provides you with the option of defining any static network servers.Figure 61. Network Topology
Access / One® Network80 Managing the Network5The following options are available with this command:◗Master Network Server ConfigurationEstablishing a master/slave relationship between network servers facilitatesefficient Wide Area Network management by reducing the amount of trafficbetween two subnets on the same network, as well as providing a singlenetwork server responsible for all Strix devices within its subnet. This featureenables a Master Network Server to be statically or dynamically assigned forevery subnet (even within the same network), which Manager/One users areredirected to if they try to log into a non-Master Network Server.The Master Network Server supports SNTP (Simple Network Time Protocol)and is responsible for sending out the correct clock for the subnet as part ofthe CIMS protocol. In this way, only the Master Network Server need derivethe clock from an independent stratum 1 or 2 clock source. If the MasterNetwork Server fails, your Access/One Network quickly detects the failure, atwhich point the network server with the next lowest IP address assumes therole of master. In this case, when the failed Master Network Server comesback online, it immediately re-establishes its role as master.Choose whether you want the system to obtain the Master Network Server IPaddress automatically (default), or use a pre-configured static IP address. Ifyou choose the latter option, enter a valid IP address in the appropriate field.◗Static Network ServersStatic network servers are added to bond subnets together, allowing you toconfigure and manage multiple subnets. You do this by starting with onesubnet and adding the Master Network Server IP addresses of other subnets totie them together. Enter the IP address of a network server module on another subnet (thedefault subnet mask is 255.255.255.255), then click on the Update button. toadd the server to a list. If you enter multiple static network servers, you mustclick on the Update button after each entry for your changes to take effect.To delete a static network server’s IP address, simply click on the X iconalongside the address.

Access / One® Network84 Managing the Network5Radius AccountingThrough a wireless interface, your Access/One Network supports RFC 2866standard RADIUS (Remote Authentication Dial-In User Service) accounting,allowing customers with existing RAS Radius-parsing scripts/tools to leverage theirinvestment as well as customize their tools to extract all available statisticalinformation. This command allows you to configure up to two RADIUS accountingservers, set up an authorization port, and establish a secret key.Figure 65. Setting Up RADIUS Accounting ServersThe following options are available with this command:◗Server 1 (IP Address or Name)Enter a valid IP address or name for Server 1.◗Server 2 (IP Address or Name)If you require a second (backup) server, enter a valid IP address or name forServer 2. Server 2 is only used if Server 1 becomes unavailable.◗PortEnter the authorization port for the primary RADIUS server (Server 1) in thisfield. This is the port the system uses when authorizing users.
Access / One® NetworkManaging the Network 855◗SecretEnter a secret key in this field for the primary RADIUS server. During theauthentication process, the server and client exchange secret keys. The secretkeys must match for communication between the server and the client tocontinue. The secret key is a valuable and necessary security measure.◗Secret ConfirmConfirm your secret key in this field.◗Checkpoint IntervalCheck this box to enable a checkpoint interval, or uncheck this box to disablethis feature.◗Send EveryOnce an interval time (in minutes) is established in this field, the reportingmodule will send interim reports for each wireless device associated to it atthis interval period.After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network. If necessary, you can click on the factory default (FD) button in thetoolbar to reset all data on this page to its factory default state.SyslogAccess/One Network offers comprehensive Syslog (system logging) functionality,including the ability to monitor Syslog events. Logged events can be sent to multipleSyslog servers, though using more than one server can impact the system’sperformance. This command allows you to:◗Define your Syslog configuration parameters.◗Assign the Syslog (system logging) server IP address.◗Define the event logging destination (Command Line Interface, SNMP SyslogMIB, or a defined Syslog server IP address).◗Establish the reporting level for each Access/One Network function (security,wireless, management, and other).
Access / One® Network86 Managing the Network5To access the Syslog window, choose Syslog from the System pull-down menu in theConfigure function.Figure 66. Configuring Access/One Network for SyslogThe following options are available with this command:◗Syslog ConfigurationThis category allows you to define the Maximum Message Length, where thecharacter length of Syslog messages will be restricted to the number youdefine here. In addition, you can enable/disable the Detailed Format featurewhich determines the level of detail reported in each message, and alsoenable a feature that forces the system to Replace Spaces with Underscores inmessages.Server IP Address added hereReporting Levels
Access / One® NetworkManaging the Network 875◗Syslog ManagementEnter a valid IP address for the Syslog server, then click on the Add button toadd this server to the list of available Syslog destinations. You can addadditional servers, but assigning multiple servers may degrade the system’sperformance. Once you’ve assigned the server(s), choose the destination foryour event logging (CLI, SNMP Syslog MIB, and/or the Syslog server youassigned). The destination(s) you choose must be enabled, so ensure that theappropriate box is checked. If you have multiple IP addresses assigned, youcan delete an IP address by clicking on the X icon next to the IP address.◗Syslog CLI SubsystemSelect the reporting level for each function (security, wireless, management,and other) from the corresponding pull-down list. Your available choices are:•none•emergency•alert•critical•error•warning•notice•inform•allIf you select all from the pull-down list, this will include the debug level. Thedebug level will significantly increase (almost double) the number of Syslogmessages that are returned and significantly degrade performance. The debuglevel should not be used for routine Syslog monitoring. For more informationabout Syslog messages, see “Syslog Messages” on page 173.After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network.

Access / One® Network88 Managing the Network5Date and TimeThis command allows you to set the time zone, define daylight saving parameters,and choose between automatic time and manual time.Figure 67. Establishing the Correct Date and Time for Your EnvironmentThe following options are available with this command:◗Time ZoneSelect the time zone from the pull-down list that applies to the geographiclocation where your Access/One Network is operating. The default time zoneis Greenwich Mean Time (GMT).Figure 68. Time Zones
Access / One® NetworkManaging the Network 895◗Daylight Saving TimeThis option allows you to configure the Daylight Saving Time for your chosentime zone. Click on the Set Daylight Saving Time button to reveal theconfiguration window.Figure 69. Configuring Daylight Saving TimeChoose the month, week, day and year from the available pull-down menusfor both the Starting Time and Ending Time to establish your daylight savingtime. To apply your selections, click on the Update button in the Set DaylightSaving Time window (not the Update button on the main page). To remove alldaylight saving time settings, simply click on the Remove button. You canalso close this window without making changes (or even after makingchanges) by clicking on the Cancel button.◗Date and TimeThis option allows you to choose between Automatic Time and Manual timesettings:•Automatic Time (SNTP)SNTP (Simple Network Time Protocol) is an adaptation of the NetworkTime Protocol (NTP), used to synchronize computer clocks within theInternet. SNTP can operate in both unicast modes (point-to-point) andbroadcast modes (point-to-multipoint). It can also operate in IP multicastmode where this service is available. If you selected Automatic Time(SNTP), you must choose whether you want the system to use DHCP toobtain the SNTP Server IP address automatically, or use a pre-configuredstatic IP address. If you select the latter option, you must enter a valid IPaddress in the SNTP Server IP Address field.
Access / One® Network90 Managing the Network5With the Automatic Time (SNTP) option selected, the master networkserver transmits time/date synchronization packets periodically to Strixdevices using the Strix Time Distribution (STD) protocol. Stack controllersuse STD to adjust their own time and date. Time and date information isdistributed in Greenwich Mean Time (GMT), allowing each device toadjust for its own time zone. This allows Access/One Network to spanlarge geographic areas while maintaining time coherence.If SNTP is configured at the network level, the master network server willproxy the SNTP time requests on behalf of your entire Access/OneNetwork. The master network server effectively queries the SNTP serverperiodically and adjusts its own time/date accordingly. STD time/dateinformation is then sent to all Strix devices on the network. If the masternetwork server fails (for any reason), all Strix devices will then query theSNTP server individually.•Manual TimeChoose this option if you want to set the date and time manually. To dothis, simply make your selections from the pull-down menus provided forhour, minute, AM/PM, month and year, then click on the day of themonth on the calendar provided.Figure 70.

If necessary, you can click on the factory default (FD) button in thetoolbar to reset all data on this page to its factory default state.Firmware UpdatesThis command allows you to set FTP parameters at the network level so that yourAccess/One Network knows where to find the new firmware (BIN) files. Proceduralinformation for updating your Access/One Network’s firmware has already beencovered in “Updating Firmware Across the Network” on page 37.If you are uncertain about your FTP server’s configuration parameters, consult withyour network administrator.
Access / One® Network92 Managing the Network5Wi-FiThis area of Manager/One contains the primary configuration commands for yourAccess/One Network in the Wi-Fi environment. Any commands executed here areapplied to all wireless modules, so make sure the changes you initiate are changesthat you want to apply to the entire network, otherwise go to “Managing Subnetsand Nodes” on page 127 or “Managing Modules” on page 133.GeneralThis command allows you to define your Access/One Network’s general radioparameters for 4.9 GHz Public safety, 802.11a and 802.11g radios. These radioparameters are applied across the entire network. If you want to set up the radioparameters for a specific wireless module, go to “Radio Parameters” on page 147.Figure 72. Setting Up General Radio Parameters
Access / One® NetworkManaging the Network 935◗Allow Association Over Long Distances (25 miles/40 km)This option allows you to set a distance (up to 25 miles or 40 kilometers) forwireless associations over long distances (the default is 3 miles). Be awarethat changing the distance here will affect all wireless modules. Werecommend setting this value at the module level. For example, if you have asingle 10 mile link and many shorter links setting this value to 10 miles willaffect all links and slow down the network.◗Frequency/Rate/Power•Transmit PowerThis option allows you to select the level of transmit power from thechoices available in the pull-down list (either Full, Half, Quarter, OneEighth, or Minimum). You can decrease the transmit power to decreasethe range of the wireless modules in your Access/One Network. Thedefault value for this parameter is Full (maximum power).Depending on the selected antenna(s) for your application—especiallyrelevant to the OWS—it may be necessary to configure the transmitpower. It is the installer's responsibility to ensure that the transmit poweris set correctly for the chosen antenna(s). Operation in a manner otherthan is represented in this document is a violation of FCC rules.For a complete listing of the maximum power settings allowed forantennas, go to “Power Settings for Antennas” on page 167.◗Advanced SettingsThese advanced settings are preconfigured with the optimum settings for yourAccess/One Network. Changing any of these settings may negatively affectthe network’s performance. For best results, leave these settings at theirdefault values.•Beacon IntervalThe beacon is a uniframe system packet broadcast by the AP to keep thenetwork synchronized. Enter a value in this field between 20 and 1000(milliseconds) that specifies the beacon interval. The default value is 100.
Access / One® Network94 Managing the Network5•Delivery Traffic Indication Message (DTIM Period)Enter a value between 1 and 255 that specifies the Delivery TrafficIndication Message (DTIM). Increasing this interval allows the station tosleep for longer periods of time resulting in power savings (in exchangefor some degradation in performance). The default value is 1.•Fragment LengthEnter a value between 256 and 2346. This setting determines the size ofthe wireless frame. Wireless frames are reassembled by your Access/OneNetwork wireless modules before being forwarded to the Ethernet port,but only if the frame is smaller than the Ethernet MTU (1536 bytes). Thedefault value is 2346.•RTS/CTS ThresholdThis is a value that determines at what frame length the RTS-CTS functionis triggered. By default, the threshold is set at its highest value. A lowervalue means that the RTS-CTS function is triggered for smaller framelengths. A lower threshold value may be necessary in environments withexcessive signal noise or hidden nodes, but may result in someperformance degradation. Enter a value between 256 and 2346 to specifythe RTS/CTS threshold. The default value is 2346.

The default is 128. Setting this fieldto 0 (zero) prevents all 802.11a client access.◗802.11a Channel SelectorThese options extend the range of 802.11a wireless capability by allowingyou to select 802.11a wireless channels. Check the corresponding box toenable an 802.11a channel of your choice.
Access / One® Network98 Managing the Network5802.11g Radio Parameters at the Network LevelThe following options are available with the Radio Parameters command for all802.11g radios at the network level:◗802.11g Radios Wireless ModeThis option allows you to select the 802.11g wireless mode from the optionsavailable in the corresponding pull-down list, including:•802.11g: This is the default standard 802.11g wireless mode.•802.11g Only (No 802.11b): This mode restricts the radio to the 802.11gwireless mode only and does not allow 802.11b compatibility.•802.11b Only (No 802.11g): This mode restricts the radio to the 802.11bwireless mode only and does not allow 802.11g compatibility.◗Maximum 802.11g ClientsThis option allows you to restrict the number of 802.11g clients that canassociate with each 802.11g access point. The default is 128. Setting this fieldto 0 (zero) prevents all 802.11g client access.◗802.11g Channel SelectorThese options extend the range of 802.11g wireless capability by allowingyou to select 802.11g wireless channels. Check the corresponding box toenable an 802.11g channel of your choice.◗802.11g (only)These options allow you to set up how your 802.11g wireless modulesperform on the network (not applicable to 802.11a radios). Options that arespecific to 802.11g radios include:
Access / One® NetworkManaging the Network 995•Protection ModeThis is a mechanism to let 802.11g devices know when they should usemodulation techniques to communicate with another 802.11b device,especially in wireless networks where there is a mixed environment thathas 802.11g and 802.11b clients (and the clients are hidden from eachother. The protection mode options include the following:–NoneThis assumes there are no wireless stations using 802.11b (11 Mbps)technology. If operating in a mixed 802.11b/g network with minimal802.11b traffic, choose this option to ensure the best performance foryour 802.11g stations.–AlwaysProtects 802.11b traffic from colliding with 802.11g traffic. Thismode is not recommended, especially if only a few wireless stationsare operating with 802.11b. Only use this mode in environmentswith heavy 802.11b traffic or where there is interference.–AutoThis is the default mode and will enable protection for 802.11gstations if your Access/One Network finds an 802.11b client. In thismode, if the 802.11b client leaves the network the protection modewill revert to None automatically.•Protection RateSets the data rate at which the RTS-CTS (Request-to-Send and Clear-to-Send) packets are sent (either 1 Mbps, 2 Mbps, 5.5 Mbps, or 11 Mbps).The 11 Mbps data rate is the default.
Access / One® Network100 Managing the Network5•Protection TypeThis option is only relevant when the Protection Mode is on. The optionshere are CTS-only or RTS-CTS. With CTS-only, the client is not requiredto send an RTS (Request-to-Send) to the AP. As long as the client receivesa CTS (Clear-to-Send) frame from the AP then the client is free to senddata. With the RTS-CTS option enabled, the client is required to send anRTS to the AP and wait for a CTS from the AP before it can send data (thisoption creates additional overhead and can cause performancedegradation). The default is CTS-only.•Short Slot Time802.11g defines the long slot time as 20 microseconds and a short slottime as 9 microseconds. 802.11b only supports the long slot time of 20microseconds. In an environment with 802.11g devices only, this option(Short Slot Time) must be enabled for better performance—givingprecedence to 802.11g traffic. Only disable this option in mixed(802.11b and 802.11g) environments. The default is enabled.•Short PreambleShort slot preamble improves network efficiency by reducing thepreamble from 128 bits to 56 bits. 802.11g is required to support bothshort and long preambles (802.11b support for a short preamble isoptional). If this option is enabled, any 802.11b clients associated withthe network must support a short preamble. The default for this option isenabled.After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network.

Check the Suppress SSIDbox if you want to prevent the broadcast of this SSID in beacons from allwireless modules in your Access/One Network (recommended).
Access / One® NetworkManaging the Network 1035Choose whether the new SSID should be tagged or untagged. However,there can be only one untagged SSID in the SSID table (the default SSIDis always untagged). From this window you also have the option ofassigning VLAN Security to the new SSID. When you have completed alldata input for the creation of your new SSID, click on the Add SSIDbutton. The new SSID is added to the list and will appear in the pull-down list in the main Client Connect window.•Deleting an SSIDTo delete an existing SSID, simply click on the X icon next to the SSIDyou want to delete.Figure 78. Deleting an SSID◗SSID Client LimitsEnter a value (up to 128) in the Maximum Clients per SSID field. The defaultis 128. If you enter a value of 0 (zero) you will effectively prevent all useraccess, with the exception of any Strix Network Connect devices.◗VLAN SecurityYou can now associate a tagged or untagged VLAN with the selected SSID. Ifyou define a tagged VLAN, you must assign a priority to it. The acceptablerange for priorities is between 0 and 7, and the priority is chosen from thepull-down list. The lower the priority level you assign, the higher the prioritywill be given by a VLAN-aware Ethernet switch. Access/One Network doesnot support these priority levels as a queuing mechanism and ignores themwhile the frame is in transit through the network. The VLAN mechanismapplies strictly to wireless stations. All devices on your Access/One Networkgenerate only untagged traffic.Click here to delete this SSID
Access / One® Network104 Managing the Network5◗Client Connect Security ModeThis option allows you to establish the authentication and encryption securitymodes for Client Connects. These include:•Authentication–Open: Used for local authentication.–Shared Key: This option is not currently supported.–Dynamic Key (802.1X): With this option, the RADIUS server gives akey to each user for unicast traffic. Multicast traffic uses the defaultkey.–WPA-PSK: With this option, the WPA (Wi-Fi Protected Access)standard uses a Pre-Shared Key (PSK) mode that does not require theRADIUS infrastructure.–WPA: This option provides WPA, a subset of the 802.11i standardthat boosts the original static WEP security by mandating 802.1xremote authentication.•Encryption–Clear: Available for Open or Dynamic authentication. Messages willbe sent unencrypted between user devices and your Access/OneNetwork nodes.–WEP: Wired Equivalency Privacy (WEP) is a security protocol forWLAN. It encrypts data using an RC4 stream cipher of 64, 128 or152 bits.–AES: Advanced Encryption Standard (AES) encrypts data using asymmetric 152 bit data block, and is generally considered the mostsecure option available.–TKIP: The Temporal Key Integrity Protocol (TKIP) is part of the IEEE802.11i encryption standard for wireless LANs, providing per-packetkey mixing, a message integrity check and a re-keying mechanism.–Auto Negotiate: With this option, the encryption mode will benegotiated in real time between the participating devices, allowingthe simultaneous use of AES and TKIP.
Access / One® NetworkManaging the Network 1055Select the desired Authentication and Encryption modes from the availableoptions. If you choose Dynamic (802.1x) or WPA authentication, you mustconfigure the RADIUS server(s) on this page (these fields only appear whenDynamic or WPA is selected as the authentication type).

When the pop-up windowappears, choose None from the pull-down list. The selected security key isremoved from the list automatically.◗Access Control ListThis option allows you to configure an Access Control List (ACL) to determinewhich user devices (stations) are allowed to connect to your Access/OneNetwork. To do this, simply click on the Manage ACL button to reveal theManage ACL window.Figure 83. Configuring an Access Control ListEncrypted KeyDefault Shared Key
Access / One® NetworkManaging the Network 1075Choose the preferred access level from the pull-down list. Your optionsinclude:•Disable: All stations/clients can request association with an SSID in yourAccess/One Network. This means that the ACL will not be checked whena new station attempts to authenticate.•Enable: All stations/clients are assigned a permission status based on theirMAC address. If the MAC address of the station attempting to gain accessis set to Deny, it will not be allowed to associate with the network. If theMAC address is set to Allow, or not configured in the ACL, the station willbe allowed network access.•Strict: Only stations assigned with Allow permissions in the ACL aregranted access to the network, regardless of encryption settings. Inaddition, if the entry is configured for an encryption key, the station isalso required to match that key before gaining access. If no ACL entryexists for a MAC address, it will not be allowed to associate with thenetwork. The ACL accepts multiple levels of authentication concurrentlyso that stations with or without encryption (or shared key authentication)can be admitted.To add a new station, click on the Add New Station button to reveal the AddNew Station window.Figure 84. Adding a New StationChanging the ACL mode for wireless stations requires a reboot.A reboot is also required when adding or deleting ACL entriesat the network level (though not at the module level).
Access / One® Network108 Managing the Network5Enter the MAC address of the new station/client, then choose the ACL typefrom the pull-down list. These options include:•Allow•Deny•Default Shared Key•64 bit (enter 10 digits)•128 bit (enter 26 digits)•152 bit (enter 32 digits)If you choose any of the encryption types, enter the key in the Unique Keyfield. Alternatively, you can choose the Default Shared Key and the systemwill use the key you assigned as the default in Client Connect Security Keys.This key will be used for all unicast messagesIf you want to assign a VLAN, go to VLAN Security to understand what youneed to do with these fields. If CoS is disabled, your Access/One Networkdoes not support VLAN priority levels as a queuing mechanism and ignoresthem while the frame is in transit through the network. The VLAN mechanismapplies strictly to wireless stations. All Access/One Network devices generateonly untagged traffic.When you have completed your Access Control List (ACL) configuration,click on the Update button to apply your changes and return to the ManageACL window. You must now click on the Update button in this window, thenclick on the Apply Configuration tab to apply all of your ACL changes acrossthe network. You can now return to the main Client Connect window.◗Client Connect PrivacyWhen enabled, this option offers Client Connect privacy by preventing Wi-Fiusers from communicating with each other on the same module. Data fromeach Wi-Fi device is sent only to the Ethernet or backhaul ports, requiring arouter or other access device for authentication before allowing the devicesto exchange data. This is important in hotel applications where wireless userscommunicate with each other via Guestek or Wayport servers. The default isdisabled.
Access / One® NetworkManaging the Network 1095◗SSID ShutdownWhen enabled, this option shuts down all SSID functionality when networkconnectivity is lost. With this feature enabled, if connectivity to the gateway islost, the access point will disassociate all attached wireless clients—the clientwill know there is a problem and will need to find another access point to re-establish connectivity with the network. The default is disabled.◗Discovery ProtocolsThis option enables the Strix Discovery Protocol (browser plug-in). Thedefault is enabled. If this option is disabled, the left pane in Manager/Onewill not be available and the auto-discovery feature will not function.◗Client Connect Privacy TagsThis option is used if you want to prevent users from seeing each other ondifferent modules. For total hotspot privacy, we recommend leaving theprivacy WLAN tags at their default values.If you want to enable VLAN tag marking for Client Connect privacy (requiredfor mesh privacy), check this box. If enabled, you must assign the tags (thedefaults are 925 and 926).After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network. If necessary, you can click on the factory default (FD) button in thetoolbar to reset all data on this page to its factory default state.Network ConnectNetwork Connect is the infrastructure used by your Access/One Network for awireless connection to an existing wired network (small or large). Each node withinthe network can utilize a wired Ethernet or wireless module (802.11a or 802.11g)for node inter-connectivity or connection to a wired legacy network.Unlike traditional wired Ethernet LAN/WAN connections used by access points andWLAN switches, Access/One Network’s wireless Network Connect option providesan advanced level of security between the network node and the LAN/WAN. Bydefault, the wireless Network Connect link utilizes AES encryption with a secret keyand cannot be compromised.
Access / One® Network110 Managing the Network5When nodes in your Access/One Network are configured for wireless NetworkConnect, the system provides several distinct advantages over a typical wirelessnetwork that uses wired connections. These advantages include:◗Secure networking◗Self tuning, rapid self-healing, and rogue device detection◗Scalability◗Simple installation◗Lowest cost of deploymentThis command allows you to define your Network Connect parameters. Thefollowing graphic shows the Network Connect window set to its default values.Figure 85. Network ConnectThe following options are available with this command:◗Peer SelectionThis option allows you to define peer selection criteria. These include eitherAutomatic Peer Selection (where your Access/One Network chooses peersautomatically, or selection by Target SSID (you must enter a valid SSID).
Access / One® NetworkManaging the Network 1115◗Auto-Mode Radio Priority (Dual Wi-Fi Radio Only)This option allows you to establish a priority for which radio on the dual bandwireless module will operate as a Network Connect in the Auto mode. Theavailable choices are:•802.11a Only•802.11a Priority, 802.11g Backup•802.11g Priority, 802.11a Backup•802.11g Only◗Self-TuningThis feature allows you to enable or disable Background Scanning andconfigure the Self-Tuning Policy. When a Network Connect module firstconnects to the network, it performs an initial scan of all available Wi-Fichannels and generates a list of potential alternate Client Connects that arereachable. Following the initial scan, the Network Connect continually scansin the background to maintain the list and enable the system to make thefollowing intelligent decisions:•When to drop the current path and select a better path, then connect tothe appropriate node (self-tuning).•When to select the best path (or detect the loss of a path) and select thenext best path, then connect to the appropriate node (self-healing).•Which APs are rogue devices.To fully optimize your network’s ability to self-tune, self-heal and detectrogue devices, we recommend that the Background Scanning feature isalways enabled (default).Disabling Background Scanning will prevent Network Connectsfrom reporting rogue AP devices.
Access / One® Network112 Managing the Network5◗Self-Tuning PolicyYou can instruct the system to Never Switch during its self-tuning process, orestablish a Switching Frequency (with 5 possible frequency states betweenstable and aggressive). When background scanning is completed, the self-tuning system determines the best potential client, based on RTD/RSSI scoresand threshold values obtained during the scanning process. Threshold valuesbecome more critical when two Client Connects are very close with theirscores. Normally, this can cause bouncing between the two Client Connects,but Access/One Network eliminates the bouncing effect by allowing you tomove the threshold switching frequency from aggressive to stable.◗Background Scan IntervalEnter a value in this field (in milliseconds) to define the interval betweenbackground scans. The default is 5000 milliseconds.◗Network Connect Security KeyTo protect wireless stations associated with each node, your Access/OneNetwork provides WEP and AES ciphers for encryption and 802.1x remoteauthentication. The inter-node Network Connect wireless uplink is protectedwith an AES static key to prevent eavesdropping. The factory configureddefault key is hidden from view to retain secrecy for a basic network, but thiskey can be changed and each network can have its own unique key.The Network Connect solution for Access/One Network preventsunauthorized wireless connections from being established to the network byblocking user traffic in the following two scenarios:•If the Network Connect is configured for the default network name(AccessOne), Manager/One forces the administrator to approve/admit thenode to the network before user traffic is bridged to the network.•If the two nodes that are wirelessly connected (via the uplink) havedifferent Network Connect security keys configured. However, if theAllow Strix default key option is enabled then a Network Connect usingthe default security key can still connect with a network using a non-default security key.
Access / One® NetworkManaging the Network 1135To assign a security key, click on the Enter Key button. In the pop-up window,select the key entry method (hexadecimal or ASCII text), then enter the keythat will serve as the default key to encrypt packets to be transmitted on awireless uplink between nodes. The key length is fixed at 152 bits. Afterentering the key, click on the Update button to assign the key and return tothe Network Connect window.Figure 86. Network Connect Security KeyEnable the Allow Strix default key option if you want to allow NetworkConnects with a default key to connect with a network using a non-defaultsecurity key. In this case, the network using a non-default security key canstill be managed remotely. The default is enabled.◗Network Connect Data Trust LevelThis feature determines whether the Client Connect will allow traffic from aNetwork Connect only (for management purposes), or from devices beyondthe Network Connect module—like a Client Connect on top of it, or Ethernetdevices attached to it. This applies only when a Network Connect uses thedefault (non-provisioned) key when associating with a Client Connect.Choose the preferred trust level policy for the Network Connect from thefollowing options:•Trust Strix Network behind Network Connect: Trust the Strix networkbehind the Network Connect.•Trust only Network Connect module: Trust only the Network Connectmodule.After inputting data (or making selections), click on the Update button to update thispage, then click on the Apply Configuration tab to propagate your changes acrossthe network.
