Configure Multimedia Optimizations

A WLAN QoS policy must exist. See Configuring a WLAN QoS Policy.

Multimedia optimizations customize the size and speed of multimedia content (voice, video, and so forth.) to deliver WLAN traffic strategically to the WLAN's managed clients and their defined QoS requirements.

To configure or edit a QoS rate limit configuration for a controller, service platform, virtual platform or access point managed WLAN:

Select Policies > Wlan QoS, then select a policy in the list to open the configuration window.
Select the Multimedia Optimizations tab.

Configure the Multicast Mask settings as follows:


Multicast 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 Secondary	Set a secondary multicast mask for the WLAN QoS policy in case the primary becomes unavailable.

Use the Accelerated Multicast drop-down list to choose one of the following 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.
Forwarding QoS Classification	This option appears if you select Automatically Detect Multicast Streams . Use the drop-down menu to select the classification to use. Options are: Trust, Voice, Video, Best Effort, Background.
Manually Configure Multicast Addresses	Select this option and specify a list of multicast addresses and classifications. Packets are accelerated when the destination addresses matches.

If you selected Manually Configure Multicast Addresses in the previous step, configure a list of addresses as follows:

Select Add to add a new entry to the list.

Configure the settings as follows:


Multicast IP Address	Enter the multicast IP address.
Classification	Use the Classification drop-down list to select the classification to use. Options are: Trust, Voice, Video, Best Effort, Background.

If necessary, you can delete a multicast IP address by selecting the icon at the right side of the list entry.

After you have completed configuring the settings, choose from the following actions:
1. Select Apply to commit the configured settings.
  
  Note
  This does not save the settings you configured; it provides a preview of your applied settings. To undo the settings you applied, select Revert.
2. Select Save to commit and save the configured settings.
  
  Note
  
  If you do not select Save, the settings that you configured are not saved when you move away from the configuration window.
