Configuring Wi-Fi Multimedia

Wi-Fi Multimedia (WMM) is used to prioritize different types of traffic. You can configure QoS settings to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.

To configure WMM:

  1. Choose Wireless > Basic Settings.
  2. In the Wireless Basic Settings Table, check the box on the left of the wireless network you want to configure.
  3. Click Edit WMM.
  4. In the SSID field, select SSID that clients use to connect to the AP.
  5. Check the WMM Enable box to enable WMM based on the IEEE 802.11e standard for this profile. WMM helps in prioritizing wireless traffic according to four access categories:
    • Voice (highest priority, 4)
    • Video (high priority, 3)
    • Best effort (medium priority, 2)
    • Background (lowest priority, 1)
  6. In the DSCP to Queue table, for each ingress DSCP, you can choose the output queue for the traffic. The Differentiated Services Code Point (DSCP) field identifies the data packet and the output queue identifies the output queue in which the packet is transmitted:
    • Voice (4) or Video (3)—High priority queue, minimum delay. Typically used to send time-sensitive data such as video and other streaming media.
    • Best Effort (2)—Medium priority queue, medium throughput and delay. Most traditional IP data is sent to this queue.
    • Background (1)—Lowest priority queue, high throughput. Bulk data that requires maximum throughput and is not time-sensitive is typically sent to this queue (FTP data, for example).

    If you want to change the output queue for packets marked with a particular DSCP, select the new output queue from the drop-down list.

    To restore the default settings, click Restore Default.

  7. Click Save.
