the station to the access point. With WMM disabled, you can still set downstream access-point-to-station QoS parameters but no station-to-access-point QoS parameters.

•To disable WMM:

USR5453-AP#set radio wlan0 wme off USR5453-AP#get radio wlan0 wme off

•To enable WMM:

USR5453-AP#set radio wlan0 wme on USR5453-AP#get radio wlan0 wme on

About Access Point and Station EDCA Parameters

AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the access point to the client station (access-point-to-station).

Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the client station to the access point (station-to-access-point). Keep in mind that station-to-access-point parameters apply only when WMM is enabled as described in “Enable/Disable Wi-Fi Multimedia” on page 239.

Understanding the Queues for Access Point and Station

The same types of queues are defined for different kinds of data transmitted from access-point-to-station and station-to-access-point but they are referenced by differently depending on whether you are configuring access point or station parameters.

Data	Access Point	Station
Voice - Highest priority queue, minimum delay. Time-sensitive data	data0	vo
such as VoIP and streaming media are automatically sent to this
queue.
Video - High priority queue, minimum delay. Time-sensitive video	data1	vi
data is automatically sent to this queue.
Best Effort - Medium priority queue, medium throughput and delay.	data2	be
Most traditional IP data is sent to this queue.
Background - Lowest priority queue, high throughput. Bulk data that	data3	bk
requires maximum throughput and is not time-sensitive is sent to this
queue (FTP data, for example).

Distinguishing between Access Point and Station Settings in QoS Commands

Access Point - To get and set QoS settings on the access point, use "tx-queue" class name in the command.

Station - To get and set QoS settings on the client station, use the "wme-queue" class name in the command.
