Appendix D Checklist for Deploying the Cisco Unified Wireless IP Phone 7921G
Configuring QoS Policies
• AVVID Priority Mapping—Yes.
• WiFi Multimedia (WMM) on radio interfaces—Enabled
Controller Settings
For detailed information about configuring QoS policies for the controller, refer
to these URLs:
• http://www.cisco.com/univercd/cc/td/doc/product/wireless/control/index.htm
• http://www.cisco.com/univercd/cc/td/doc/product/wireless/control/c44/ccfig40
/index.htm
When using a controller, add the following QoS policies:
• Platinum (voice)—Apply this policy to your voice WLAN SSID/VLAN for
both incoming and outgoing traffic.
• Silver (best effort)—Apply this policy to your data WLAN SSID/VLAN for
both incoming and outgoing traffic.
• WLAN configuration screen for the voice WLAN SSID/VLAN—For the
7921G Phone Support field, check the AP CAC Limit checkbox to enable
QoS Element for Wireless Phones (QBSS).
• General Controller configuration screen—Set Aggressive Load Balancing to
Disabled.
Switch Configuration
To implement QoS in the connected Ethernet switch individual configurations
will vary; however, you can use this example of QoS commands as a guide.
