Configuring a WLAN QoS Policy

This procedure describes how to create a new policy, or edit or delete an existing policy.

  1. Select Policies > WLAN QoS.
    The WLAN QoS window opens. If any WLAN QoS policies are configured, they appear in a list in the Wlan QoS pane. The total number of policies is shown in parentheses.

    The Wlan QoS pane column heading topic definitions are as follows:

    Policy Name The name assigned to this WLAN QoS policy. The assigned policy name cannot be modified.
    Wireless Client Classification Each policy's Wireless Client Classification as defined for this WLAN's intended traffic. The Classification Categories are the different WLAN-WMM options available to a radio. Classification types include:
    • WMM – Implies WiFi Multimedia QoS extensions are enabled on this radio. This allows different traffic streams between the wireless client and the access point to be prioritized according to the type of traffic (voice, video etc). WMM classification is required to support the high throughput data rates required of 802.11n device support.
    • Voice– Optimized for voice traffic. Implies all traffic on this WLAN is prioritized as voice traffic on the radio.
    • Video – Optimized for video traffic. Implies all traffic on this WLAN is prioritized as video traffic on the radio.
    • Normal – Optimized for best effort traffic. Implies all traffic on this WLAN is prioritized as best effort traffic on the radio.
    • Low – Optimized for background traffic. Implies all traffic on this WLAN is low priority on the radio.
    • Non-Unicast – Optimized for non-Unicast traffic. Implies all traffic on this WLAN is designed for broadcast or multicast.
    SVP Prioritization A green check mark defines the policy as having Spectralink Voice Prioritization (SVP) enabled to allow the wireless controller to identify and prioritize traffic from Spectralink/Polycomm phones using the SVP protocol. Phones using regular WMM and SIP are not impacted by SVP prioritization. A red "X" defines the QoS policy as not supporting SVP prioritization.
    WMM Power Save Enables support for the WMM based power-save mechanism, also known as Unscheduled Automatic Power Save Delivery (U-APSD). This is primarily used by voice devices that are WMM capable. The default setting is enabled.
    Multicast Mask Primary 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, the 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 The secondary multicast mask defined for each listed QoS policy.
  2. Choose from the following actions:
    1. Select the sort icon adjacent to a column heading to sort the data by the heading topic. By default, the data is sorted in ascending order, as indicated by the direction of the arrow in the icon . Toggle the icon to sort the column data in descending order . The "1" indicates by which column heading topic the data is currently sorted.
    2. Select an existing policy in the list, or select the Edit icon to the right of the policy you want to modify.
      The Rate Limit configuration window appears for the selected policy. You can open the Multimedia Optimizations and WMM configuration screens by selecting the appropriate tabs. Edit the policy parameters in accordance with the instructions in the steps of the relevant procedure. You cannot edit the Policy Name.
    3. Select the Delete icon to the right of the policy you want to remove.
    4. Select the Add icon to create a new policy.
      When you select Add, the Add Policy window appears.
      1. Assign a policy Name representative of its access permissions, location or intended wireless client user base. The name cannot exceed 32 characters.

      2. Select Add to save the policy.

        The Rate Limit configuration screen opens by default. You can open the Multimedia Optimizations and WMM configuration screens by selecting the appropriate tabs.

  3. Continue with the WLAN QoS policy configuration as described in the following procedures:
