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.
