Configure Radio QoS Multimedia Optimizations Policy

You must be in the process of configuring a new Radio QoS policy or modifying an existing policy to use this procedure.

Use the Multimedia Optimizations tab to configure advanced multimedia QoS and Smart Aggregation parameters for the radio QoS policy.

  1. Go to Policies > Radio QoS > Multimedia Optimizations.
  2. Configure the Accelerated Multicast parameters for this radio QoS policy as described in Accelerated Multicast Parameters.
    Table 1. Accelerated Multicast Parameters
    Parameter Description
    Maximum multicast streams allowed Specify the maximum number of multicast streams (between 0 and 256) permitted to use accelerated multicast. The default value is 25.
    When wireless client count exceeds the above limit When the wireless client count using accelerated multicast exceeds the maximum number, set the radio to either Reject new wireless clients or Revert existing clients to a non-accelerated state.
    Maximum multicast streams per client Specify the maximum number of multicast streams (between 1 and 4) wireless clients can use. The default value is 2.
    Packets per second for multicast flow for it to be accelerated Specify the threshold of multicast packets per second (between 1 and 500) that triggers acceleration for wireless clients. The default value is 25.
    Timeout for wireless clients Specify a timeout value in seconds (between 5 and 6,000) for wireless clients to revert to a non-accelerated state. The default value is 60.
  3. Configure Smart Aggregation parameters as described in Smart Aggregation Parameters.
    Smart Aggregation enhances frame aggregation by dynamically selecting the time when the aggregated frame is transmitted. In a frame‘s typical aggregation, an aggregated frame is sent when it meets one of these conditions:
    • A predefined number of aggregated frames is reached
    • An administrator defined interval has elapsed since the first frame (of a set of frames to be aggregated) was received
    • An administrator defined interval has elapsed since the last frame (not necessarily the final frame) of a set of frames to be aggregated was received

    With this enhancement, an aggregation delay is set uniquely for each traffic class. For example, voice traffic is not aggregated but is sent immediately, while background data traffic is sent only after frames have been aggregated.

    Table 2. Smart Aggregation Parameters
    Parameters Description
    Smart Aggregation Select to enable smart aggregation and dynamically define when an aggregated frame is transmitted. Smart aggregation is disabled by default.
    Max Delay for Best Effort Set the maximum time (in milliseconds) to delay best effort traffic. The default setting is 150 milliseconds.
    Max Delay for Background Set the maximum time (in milliseconds) to delay background traffic. The default setting is 250 milliseconds.
    Max Delay for Streaming Video Set the maximum time (in milliseconds) to delay streaming video traffic. The default setting is 150 milliseconds.
    Max Delay for Video Conferencing Set the maximum time (in milliseconds) to delay video conferencing traffic. The default setting is 40 milliseconds.
    Max Delay for Voice Set the maximum time (in milliseconds) to delay voice traffic. The default setting is 0 milliseconds.
    Minimum frames per Aggregate limit Set the minimum number of frames to aggregate in a frame before it is transmitted. The default setting is 8 frames.
    Max Mesh Links Set the maximum number of mesh hops for smart aggregation. The default setting is 3.
  4. After you have completed configuring the settings, choose from the following actions:
    1. Select Revert to restore default settings.
      Note

      Note

      You cannot restore default settings after applying or saving changes.
    2. Select Apply to commit the configured settings.
      Note

      Note

      This does not permanently save the settings you configured. If you perform a Reload (warm reboot), applied settings will be lost.
    3. Select Save to commit and save the configured settings.
      Note

      Note

      If you do not select Apply or Save, the settings that you configured are not saved when you move away from the configuration window.
