Configuration Tip for Cisco Aironet Access Points

If you are using EAP-FAST, you must increase the EAP request (802.1x) timeout to at least 20 seconds to ensure that the phone gets the PAC credentials successfully.

To change the request timeout on the controller, follow these steps:

Procedure


Step 1 Use SSH or Telnet to access the Cisco Unified wireless LAN controller.

Step 2 Enter config advanced eap request-timeout 20.

Step 3 Enter save config.

Step 4 Enter y to confirm.


Configuring QoS Policies

To ensure that voice traffic receives the highest priority in the WLAN and to place signaling traffic in a higher priority than data traffic, you need to make these changes to QoS policies and device settings.

Access Point Configuration Settings

For detailed information about configuring the Cisco Aironet Access Points, refer to this URL:

http://www.cisco.com/en/US/products/hw/wireless/ps430/tsd_products_support_configure.html

For the Cisco IOS access points, add the following Classifications to your Cisco IOS Access Point QoS policy:

DSCP Expedited Forwarding—COS Voice <10ms Latency (6)

Apply this policy to your voice VLAN for both incoming and outgoing traffic.

DSCP Best Effort—COS Best Effort (0)

Apply this policy to your data or native VLAN for both incoming and outgoing traffic.

Under the Advanced tab, set the following:

QoS Element for Wireless Phones—Enable.

Dot11e—Enable.

IGMP Snooping—Enable.

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 this URL:

http://www.cisco.com/en/US/products/ps6366/tsd_products_support_series_home.html

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.

mls qos
mls qos map cos-dscp 0 8 16 24 34 46 48 56
mls qos map ip-prec-dscp 0 8 16 24 34 46 48 56
