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

Understanding the Queues for AP and Station

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

Data

AP

Station

Voice - High 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

data1

vi

video data is automatically sent to this queue.

 

 

Best Effort - Medium priority queue, medium throughput and

be

delay. Most traditional IP data is sent to this queue.

 

 

Background - Lowest priority queue, high throughput. Bulk data

data3

bk

that requires maximum throughput and is not time-sensitive is

 

 

sent to this queue (FTP data, for example).

 

 

Distinguishing between AP and Station Settings in QoS Commands

Access Point - To get and set QoS settings on the access point (AP), 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.

Get QoS Settings on the AP

To view the current QoS settings and queue names for AP-to-station parameters:

AT-TQ2403# get tx-queue
