Quality of Service (QoS) is an important feature of the end-to-end AVC functionality. Proper QoS 
support enables prioritization and policy enforcement on NBAR identified applications. AVC related 
QoS policies are applied on any direction (Upstream/Downstream) of the client traffic.

Upstream traffic refers to traffic from Wireless Client -> AP -> Switch -> Controller.

Downstream traffic refers to traffic from Controller -> Switch -> AP -> Wireless Client.

Application control is done on the AP for Upstream QoS and Switch/Controller for Downstream QoS 
with NBAR classification done on the AP. Client QoS Policies are supported by NBAR for this feature. 
You can configure and monitor Application Visibility and link it to QoS from both the GUI and CLI.

IPv6 packet classification is not supported.

Multicast traffic is not supported.

Complete these steps:

From a web browser, open the WLC GUI interface and then from the main menu, go to Configuration 
> Wireless > WLAN. Perform 

 if the WLAN is already created or exists and you want to enable 

AVC on that particular WLAN.

To create a new WLAN on the WLC, go to Configuration > Wireless > WLAN and click New. 

Enter a number in the WLAN ID text box and a name in the SSID and Profile Name text boxes.
