3. Either select the 

Add

 button to define a new WLAN QoS policy, or select an existing WLAN QoS policy 

and select 

Edit 

to modify its existing configuration. Existing QoS policies can be selected and deleted as 

needed.

A 

Quality of Service

 (QoS) policy screen displays for the new or selected WLAN. The screen displays the 

WMM tab by default, but additional tabs also display for WLAN and wireless client rate limit 
configurations. For more information, refer to the following:

•

Configuring a WLAN’s QoS WMM Settings

•

Configuring a WLAN’s QoS Rate Limit Settings

•

Configuring a WLAN’s QoS Wireless Client Rate Limit Settings

6.2.1 Configuring a WLAN’s QoS WMM Settings

Using WMM, end-user satisfaction is maintained in a wider variety of environments and traffic conditions. 
WMM makes it possible for both home networks and Enterprises to decide which data streams are most 
important and assign them a higher traffic priority.

WMM’s prioritization capabilities are based on the four access categories. The higher the access category, 
the higher the probability to transmit this kind of traffic over the wireless controller managed WLAN. ACs 
were designed to correspond to 802.1d priorities to facilitate interoperability with QoS policy management 
mechanisms. WMM enabled wireless controllers/ access points coexist with legacy devices 
(not WMM-enabled).

Packets not assigned to a specific access category are categorized by default as having best effort priority. 
Applications assign each data packet to a given access category packets are then added to one of four 
independent transmit queues (one per access category - voice, video, best effort or background) in the client. 
The client has a collision resolution mechanism to address collision among different queues, which selects 
the frames with the highest priority to transmit.

The same mechanism deals with external collision, to determine which client should be granted the 

opportunity to transmit

 (TXOP). The collision resolution algorithm responsible for traffic prioritization is 

probabilistic and depends on two timing parameters that vary for each access category.

• The minimum interframe space, or

 Arbitrary Inter-Frame Space Number

 (AIFSN)

• The contention window, sometimes referred to as the random backoff wait

Both values are smaller for high-priority traffic. The value of the contention window varies through time. 
Initially the contention window is set to a value that depends on the AC. As frames with the highest AC tend 
to have the lowest backoff values, they are more likely to get a TXOP.

After each collision the contention window is doubled until a maximum value (also dependent on the AC) is 
reached. After successful transmission, the contention window is reset to its initial, AC dependant value. 
The AC with the lowest backoff value gets the TXOP.

To configure a WMM configuration for a WLAN:

1. Select 

Configuration 

> 

Wireless

 > 

Wireless LAN QoS Policy

 to display existing WLANs. 

NOTE: 

When using a wireless client classification other than WMM, only legacy rates 

are supported on that WLAN.
