Configuration Guide Known Limitations IMPORTANT NOTE: VIEW Certification testing verifies that the user access radio of the BelAir AP 50/100/200 meets the VIEW technical requirements for supporting SpectraLink 8000 Wireless Telephones in a typical enterprise deployment. Testing is conducted in a laboratory where neither outdoor AP coverage area/range nor multiple mesh backhaul hops are considered. Because Wi-Fi mesh deployments vary significantly in terms of wireless backhaul, actual performance can not be guaranteed in a mesh environment. In a BelAir mesh, only Point-to-Point backhaul links with few hops are appropriate for voice traffic. Point-to-Multipoint or Multipoint-to-Multipoint backhaul links cannot be used. BelAir supports a variety of backhaul radio technologies. Only the Wi-Fi backhaul radios were tested during VIEW Certification. WMM must be disabled.

Configuration Guide Configuration Settings Using the Web Interface The following table contains the configuration parameters recommended for interoperability with SpectraLink 8000 Wireless Telephones. Mode: AP SVP: Enable Voice SSID: Map to VLAN 100 QoS mapping: Map VLAN 100 to queue 3 Antenna Diversity: Enable BelAir access radios implement SVP. BelAir backhaul radios can use VLANs to assign voice priority to SpectraLink traffic or they can use the 802.1p User Priority field to prioritize traffic. The configuration shown above uses VLAN prioritization. Any VLAN ID can be used. In the sample configuration given here, we chose a VLAN ID of 100. Connect to Web interface Open a Web browser window and enter the BelAir node s IP address in the navigation bar. Then log in with your BelAir administrative credentials. 10 PN: 1725-36065-001_D.doc
BelAir Networks: BelAir50, BelAir100, BelAir200 Configure the access radio 1. Click the ACCESS button. 2. In the navigation pane, click General Config. 3. Make sure that the Radio State is set to Enable. 4. Set the Channel and Tx power levels according to deployment plan. 5. If you are using the internal access antenna, then the Antenna (Antenna Gain) should be set to 8 dbi; otherwise, choose the antenna setting corresponding to your external antenna. 6. WMM support must be disabled. 7. The QoS Mapping setting is irrelevant for SpectraLink 8000 Wireless Telephones because the SVP support overrides it, therefore the default QoS Mapping of BOTH can be used. 8. Make sure that QoS Schedule is set to SPQ (strict priority queuing), and the check box for QoS Acm: VOICE is not selected so that access control mandatory (Acm), which is part of WMM call admission control, is not used. 9. Click the Apply button. PN: 1725-36065-001_D.doc 11
Configuration Guide BelAir s internal access antennas have 8 dbi gain, which is the default setting for this field. If a different antenna is used, then this setting should be changed accordingly. Please refer to the BelAir Hardware Products: Deployment Guidelines manual for more information. Set up the voice SSID 1. Click the ACCESS button. 2. Click SSID Config in the navigation pane. 3. If you have not done so already, set up an SSID for data users. 4. Select an unused SSID, in this example 2. 5. Click the Enable SSID button. 12 PN: 1725-36065-001_D.doc
BelAir Networks: BelAir50, BelAir100, BelAir200 6. Enter your new voice SSID name. 7. Make sure that MBSSID is Disabled. 8. In this example configuration, we mapped the voice SSID to VLAN 100 and enabled Intra-AP client to client communications. 9. Select your privacy mode, and enter a Key as indicated. 10. Click the Apply button. PN: 1725-36065-001_D.doc 13
Configuration Guide MBSSID must be Disabled so that there is a single SSID carrying SpectraLink voice traffic. If MBSSID is enabled, each SSID gets its own BSSID, causing the SpectraLink 8000 SVP Server to not work properly, since the SVP Server would perceive the two SSIDs on an AP to be two different APs. Suppressed refers to whether the SSID gets its own beacon. When MBSSID is enabled for an SSID, it can only be broadcast (i.e., nonsuppressed) if it is the first SSID. The SpectraLink 8000 Wireless Telephones work fine with an SSID that is either broadcast or suppressed. Intra-AP client to client communications setting relates to whether client devices can communicate directly with one another. In certain VoIP-based PBX environments, the SpectraLink 8000 Wireless Telephones need to communicate directly with one another, therefore the setting must be enabled in those instances. Otherwise you may wish to disable this setting to slightly enhance security. It is not recommended to use RADIUS authentication, which is referred to as EAP/DOT1X in BelAir s Web interface. 14 PN: 1725-36065-001_D.doc
BelAir Networks: BelAir50, BelAir100, BelAir200 Set up QoS 1. Click the SYSTEM button. 2. In the navigation pane, click QoS Configuration. 3. If the top-left button is labeled Disable SVP, then SVP is already enabled. Otherwise it will be labeled Enable SVP. Enable SVP if it is not already enabled. 4. Check the UP to Queue Mapping configuration section to verify that only 6 Voice and 7 Network load are mapped to Queue 3. If any other User Priority (UP) values are mapped to Queue 3, then remap them to a different queue. 5. In the Vlan to Queue Mapping Configuration section, enter the voice Vlan ID (VLAN 100 in our example), select 3 highest for the Queue, and click the Add button. 6. If you made changes here, then click the Apply button at the bottom of this section. PN: 1725-36065-001_D.doc 15
