Configure WMM QoS Priority Settings

Wi-Fi Multimedia (WMM) is a subset of the 802.11e standard. WMM allows wireless traffic to have a range of priorities, depending on the type of data. Time-dependent information, such as video or audio, has a higher priority than normal traffic. For WMM to function correctly, wireless clients also need to support WMM.

By enabling WMM, you allow Quality of Service (QoS) control for upstream traffic flowing from a wireless client to the UTM9S or UTM25S and for downstream traffic flowing from the UTM9S or UTM25S to a wireless client.

WMM defines the following four queues in decreasing order of priority:

•Voice (Queue 4). The highest priority queue with minimum delay, which makes it ideal for applications like VoIP and streaming media.

•Video (Queue 3). The second highest priority queue with low delay is given to this queue. Video applications are routed to this queue.

•Best Effort (Queue 2). The medium priority queue with medium delay is given to this queue. Most standard IP applications use this queue.

•Background (Queue 1). The low priority queue with high throughput. Applications, such as FTP, that are not time-sensitive but require high throughput can use this queue.

Differentiated Services (DiffServ) QoS packet matching lets you map each Differentiated Services Code Point (DSCP) value (0 to 63) to one queue (1, 2, 3, or 4). You can map different DSCP values to the same queue. Based on the DSCP value in a packet’s IP header, the packet is placed in the queue to which you mapped the DSCP value.

To enable and configure WMM QoS priority settings for a wireless profile:

1.On the Wireless Profiles screen (see Figure 341 on page 588), select the check box to the left of the wireless profile for which you want to configure the WMM QoS priority settings.

2.Click the WMM table button. The WMM screen displays.

Note: The default wireless profile with profile name UTM9S or UTM25S is referred to as virtual access point zero (VAP0). If you add more wireless profiles, they are referred to as VAP1, VAP2, and VAP3.
