Configuring Multimedia Optimizations

To configure a QoS rate limit configuration for a WLAN:

1. Select Configuration → Wireless → WLAN QoS Policy to display existing QoS policies available to WLANs.
2. Click Add button to create a new QoS policy or Edit to modify the properties of an existing WLAN QoS policy.
3. Select the Multimedia Optimizations tab.
   

   WLAN QoS Policy Screen - Multimedia Optimizations Tab

   
4. Configure the following parameters for to the Multicast Mask:

   Multicast Mask Primary

   Configure the primary multicast mask defined for each listed QoS policy. Normally all multicast and broadcast packets are buffered until the periodic DTIM interval (indicated in the 802.11 beacon frame), when clients in power save mode wake to check for frames. However, for certain applications and traffic types, an administrator may want the frames transmitted immediately, without waiting for the DTIM interval. By configuring a primary and secondary multicast mask, an administrator can indicate which frames are transmitted immediately. Setting masks is optional and only needed if there are traffic types requiring special handling.

   Multicast Mask Secondary

   Set a secondary multicast mask for the WLAN QoS policy. Normally all multicast and broadcast packets are buffered until the periodic DTIM interval (indicated in the 802.11 beacon frame), when clients in power save mode wake to check for frames. However, for certain applications and traffic types, an administrator may want the frames transmitted immediately, without waiting for the DTIM interval. By configuring a primary and secondary multicast mask, an administrator can indicate which frames are transmitted immediately. Setting masks is optional and only needed if there are traffic types requiring special handling.

5. Set the following Accelerated Multicast settings:

   Disable Multicast Streaming	Select this option to disable all accelerated multicast streaming on the WLAN.
   Automatically Detect Multicast Streams	Select this option to have multicast packets converted to unicast to provide better overall airtime utilization and performance. The administrator can either have the system automatically detect multicast streams and convert all detected multicast streams to unicast, or specify which multicast streams are converted to unicast. When the stream is converted and queued for transmission, a number of classification mechanisms can be applied to the stream, and the administrator can select the desired classification type. Use the Forwarding QoS Classification drop-down list to select the classification to use.
   Manually Configure Multicast Addresses	Select this option and specify a list of multicast addresses and classifications. Packets are accelerated when the destination addresses matches.

6. Click OK when completed to update this WLAN's multimedia optimization settings. Click Reset to revert the screen to its last saved configuration.
