transmission behaviour on the access point only, not to that of the client stations.

Notes

•For the Guest interface, QoS queue settings apply to the access point load as a whole (both BSSes together).

•Internal and Guest network traffic is always queued together.

Configuring Quality of Service includes:

•Configuring AP EDCA Parameters

•Enabling/Disabling Wi-Fi Multimedia

•Updating Settings

Configuring AP EDCA Parameters

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

Description

Queue	Queues are defined for different types of data transmitted from the access
	point-to the client station:
	Data 0 (Voice)
	Highest priority queue, minimum delay. Time-sensitive data such as VoIP and
	streaming media are automatically sent to this queue.
	Data 1(Video)
	Highest priority queue, minimum delay. Time-sensitive video data is
	automatically sent to this queue.
	Data 2 (best effort)
	Medium priority queue, medium throughput and delay. Most traditional IP data
	is sent to this queue.
	Data 3 (Background)
	Lowest priority queue, high throughput. Bulk data that requires maximum
	throughput and is not time-sensitive is sent to this queue (FTP data, for exam-
	ple).
	For more information, see “QoS Queues and Parameters to Coordinate Traffic
	Flow” on page 144.
AIFS	The Arbitration Inter-Frame Spacing (AIFS) specifies a wait time in milliseconds
(Inter-Frame Space)	for data frames.
	Valid values for AIFS are 1 through 255.
	For more information, see “EDCF Control of Data Frames and Arbitration Inter-
	frame Spaces” on page 145.
