Xirrus Wi-Fi Array: XS-3500/3700/3900 Introduction Polycom’s Voice Interoperability for Enterprise Wireless (VIEW) Certification Program is designed to ensure interoperability and high performance between SpectraLink Wireless Telephones and Xirrus Wi-Fi Array infrastructure products. The products listed below have been thoroughly tested in Polycom’s lab using the VIEW Certification Test Plan.
Configuration Guide Known Limitations Voice quality may be impaired in an environment with heavy wireless TCP traffic, such as FTP data transfers. Access Point Capacity and Positioning Please refer to the Polycom Deploying Enterprise-Grade Wi-Fi Telephony white paper. This document covers the security, coverage, capacity and QoS considerations necessary for ensuring excellent voice quality with enterprise Wi-Fi networks.
Xirrus Wi-Fi Array: XS-3500/3700/3900 Network Topology The following topology was used for VIEW Certification testing. PN: 1725-36061-001_C.
Configuration Guide Configuration Settings Xirrus Arrays initially boot with all radios disabled except for the monitor radio. The monitor radio may be left enabled and in no way interferes with the SpectraLink Wireless Telephones; however it was disabled for the certification process for simplicity.
Xirrus Wi-Fi Array: XS-3500/3700/3900 The monitor radio may also be disabled with the Web Management Interface (WMI) as shown below. 1. In the navigation pane, click IAP Settings. 2. In the IAP Settings screen, clear the Enabled check box for IAP abg2. 3. Click the Apply button. Figure 1: Disabling the Monitor Radio PN: 1725-36061-001_C.
Configuration Guide Setting Radio Channels With the SpectraLink Wireless Telephones operating in 802.11b mode, at least one of the Wireless LAN Array’s Integrated Access Points (IAPs) must be set to the 2.4 GHz band. Any of the Array’s four abg radios may be used, and up to three may be used simultaneously. However, the radios must be set to the non-overlapping channels 1, 6, and 11.
Xirrus Wi-Fi Array: XS-3500/3700/3900 Configuring an SSID An SSID for the phones must be set on the Array. The following CLI commands show how to implement an SSID called ‘spec’. Xirrus_WLAN_Array(config)# ssid Xirrus_WLAN_Array(config-ssid)# add spec Xirrus_WLAN_Array(config-ssid-spec)# broadcast on Xirrus_WLAN_Array(config-ssid-spec)# show SSID "spec" Settings ================================================= State Enabled Active Yes Encryption None VLAN Name VLAN Number QoS Level 2 Active Band 802.
Configuration Guide This screen shows how to set up the SSID in the WMI. 1. In the navigation pane, click SSID Management. 2. Type the name in the New SSID Name: field near the top of the SSID Management screen. 3. Click the Create button in the upper right corner of the screen. 4. The name appears in the SSID list toward the center of the page. 5. Click the name and select the appropriate features below. 6. Be sure to click the Enable option on the Broadcast SSID line.
Xirrus Wi-Fi Array: XS-3500/3700/3900 Setting Radio Cell Size The radio transmit powers and receive sensitivities should be set appropriately for the environment in which they are operating. The simplest way to do this is to pick an operating cell size for them. The following CLI commands illustrate how to set a small cell size on three of the abg radios. Please see the Xirrus Wi-Fi Array Users Guide for a detailed explanation of radio transmit power, receive sensitivities and cell sizing.
Configuration Guide This screen shows how to set the cell size and enable the radios via the IAP Settings page of the WMI. 1. In the navigation pane, click IAP Settings. 2. In the IAP Settings page, click the Enabled check box for each radio you wish to enable. 3. In the Cell Size column, select the desired cell size for each radio. 4. Click Apply to initiate the changes to the Array.
Xirrus Wi-Fi Array: XS-3500/3700/3900 Security Enabling WPA-PSK For WPA-PSK mode, the global encryption cipher method must be set to TKIP with the following CLI commands: Xirrus_WLAN_Array(config)# security Xirrus_WLAN_Array(config-security)# wpa tkip on Xirrus_WLAN_Array(config-security)# wpa aes off Xirrus_WLAN_Array(config-security)# show Global Security Settings Summary -------------------------------WEP: key 1 size : not set (default) key 2 size : not set key 3 size : not set key 4 size : not set WPA:
Configuration Guide This screen shows how the global encryption cipher can be set through the WMI. 1. In the navigation pane, click Global Settings. 2. In the Global Settings screen, click the Yes option on the TKIP Enabled line. 3. Click the Apply button to save the settings. Figure 4: Global WPA Settings 14 PN: 1725-36061-001_C.
Xirrus Wi-Fi Array: XS-3500/3700/3900 Setting the Pre-Shared Key The pre-shared key must be provided next. In the example below the passphrase is set to ‘11111111’.
Configuration Guide This screen shows how to set the encryption and passphrase in the SSID Management page of the WMI. 1. In the navigation pane, click SSID Management. 2. Select the correct SSID from the list at the center top of the page. 3. On the Security Type line, select WPA from the drop-down list. 4. On the Security Settings line, click the SSID Specific Settings option. 5. On the PSK Authentication line, click the Yes option. 6. Enter and verify the WPA Preshared Key. 7.
Xirrus Wi-Fi Array: XS-3500/3700/3900 Enabling WPA2-PSK If WPA2-PSK mode is desired then the global encryption cipher method should be set to AES with the following CLI commands: Xirrus_WLAN_Array(config)# security Xirrus_WLAN_Array(config-security)# wpa aes on Xirrus_WLAN_Array(config-security)# wpa tkip off Xirrus_WLAN_Array(config-security)# show Global Security Settings Summary -------------------------------WEP: key 1 size : not set (default) key 2 size : not set key 3 size : not set key 4 size : not
Configuration Guide Now provide the pre-shared key (‘11111111’ in this example): Xirrus_WLAN_Array(config)# security Xirrus_WLAN_Array(config)# ssid Xirrus_WLAN_Array(config-ssid)# edit Xirrus_WLAN_Array(config-ssid-spec)# Xirrus_WLAN_Array(config-ssid-spec)# Xirrus_WLAN_Array(config-ssid-spec)# spec encryption wpa2 ssid_specific passphrase 11111111 show SSID "spec" Settings ================================================= State Enabled Active Yes Encryption SSID specific WPA2 VLAN Name VLAN Number QoS
Xirrus Wi-Fi Array: XS-3500/3700/3900 The global encryption cipher for WPA2-PSK can also be set through the WMI as illustrated in Figure 4 Global WPA Settings. The difference between the WPA-PSK and WPA2-PSK settings is that, for WPA2PSK, No should be selected on the TKIP Enabled line, and Yes should be selected on the AES Enabled line. Similarly, the SSID specific settings for WPA2-PSK may be applied as shown in Figure 5 SSID Specific WPA Settings. For Security Type select WPA2 instead of WPA.
