Wireless Controller
WMM defines the following four queues in decreasing order of priority:
Voice. The highest priority queue with minimum delay, which makes it ideal for
applications such as voice over IP (VoIP) and streaming media.
Video. The second highest priority queue with low delay is given to this queue. Video
applications are routed to this queue.
Best Effort. The medium priority queue with medium delay is given to this queue. Most
standard IP applications use this queue.
Background
. Low priority queue with high throughput. Applications, such as FTP
, that
are not time-sensitive but require high throughput can use this queue.
QoS prioritization and coordination of WiFi medium access is enabled automatically. QoS
settings on the access point control downstream traffic that flows from the access point to the
client station (AP Enhanced Distributed Channel Access [EDCA] parameters) and the
upstream traffic that flows from the client station to the access point (Station EDCA
parameters).
The Advanced QoS Settings page lets you change the QoS settings per profile group and per
radio for upstream traf
fic flowing from the station (that is, the WiFi client) to managed access
points and the downstream traf
fic flowing from managed access points to the station. These
settings are applied only to managed access points that are capable of supporting these
settings.
Disabling WMM deactivates QoS control of station EDCA parameters for upstream traffic
flowing from the client station to the access point. (Y
ou can change the settings for the station
EDCA parameters, but these settings do not take ef
fect until you enable WMM.) However,
when WMM is disabled, you can still set some parameters for downstream traffic flowing from
the access point to the client station (AP EDCA parameters), and these settings do take
effect even when WMM is disabled.
Configure Quality of Service for a Profile Group
You can configure Quality of Service (QoS) settings for each advanced profile group.
To configure the QoS settings for a profile group:
1. Open a web browser, and in the browser
’s address field, type the wireless controller’s IP
address.
By default, the IP address is 192.168.0.250.
The wireless controller’s login window opens.
2. Enter your user name and password.
3. Click the Login button.
The wireless controller’s web management interface opens and displays the Summary
page.
4. Select Configuration > W
ireless >
Advanced > QoS.
