Configuring Multicast CAC

Configuring Multicast CAC

Context

Multicast Call Admission Control (CAC) is a function that controls access of multicast users based on various rules to ensure multicast service availability. You can configure CAC based on multicast bandwidth or the number of multicast group memberships. These two CAC modes are independent of each other and can be used independently or together.

  • CAC based on multicast bandwidth

    If the multicast bandwidth is insufficient, new users are prevented from joining multicast groups.

    You can configure bandwidth-based CAC globally or for a specified VAP, or both. Bandwidth-based CAC for a specified VAP takes effect only for the VAP, while global bandwidth-based CAC takes effect for all VAPs. If you have configured bandwidth-based CAC globally and for a specified VAP simultaneously, new users cannot join multicast groups when the global multicast bandwidth or the multicast bandwidth of the VAP is insufficient.

  • CAC based on the number of multicast group memberships

    When the number of multicast group memberships reaches the maximum value, new users are prevented from joining multicast groups.

    You can configure the maximum number of multicast group memberships globally or for a specified VAP, or both. The maximum number of multicast group memberships set for a specified VAP takes effect only for the VAP, while the maximum number set globally takes effect for all VAPs. If you have configured CAC based on the number of multicast group memberships globally and for a specified VAP simultaneously, new users cannot join multicast groups when the number of multicast group memberships in the system or on the VAP reaches the maximum value.

Pre-configuration Tasks

Before configuring multicast CAC, complete the following tasks:

Procedure

  • Configure CAC based on multicast bandwidth.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      igmp-snooping group-bandwidth start-group-address start-group-address end-group-address end-group-address bandwidth bandwidth-value

      The global bandwidth limit is configured.

      By default, the bandwidth of global multicast groups is not configured.

      You can configure the bandwidth of multicast groups in a system view according to the actual bandwidth of a multicast program. This configuration takes effect globally and for a specified VAP. When users request to order this multicast program, the AP collects statistics on the current multicast bandwidth according to the bandwidth configured globally or for a VAP and the number of multicast group memberships, and compares the current bandwidth with the configured maximum bandwidth to determine whether to allow users to order this multicast program.

    3. Configure bandwidth-based CAC globally or for a specified VAP according to service requirements.

      • Configure bandwidth-based CAC globally.

        1. Run the igmp-snooping max-bandwidth max-bandwidth command to set a global bandwidth limit.

          By default, the maximum multicast bandwidth is not globally configured.

      • Configure bandwidth-based CAC for a specified VAP.

        1. Run the wlan command to enter the WLAN view.

        2. Run the traffic-profile name profile-name command to enter the traffic profile view.

          By default, the system provides the traffic profile default.

        3. Run the igmp-snooping max-bandwidth max-bandwidth command to configure the maximum multicast bandwidth for a specified VAP.

          By default, the maximum multicast bandwidth is not configured for a VAP.

        4. Run the quit command to return to the WLAN view.

        5. Run the vap-profile name profile-name command to enter the VAP profile view.

        6. Run the traffic-profile profile-name command to bind the traffic profile to the VAP profile.

          By default, the traffic profile default is bound to a VAP profile.

  • Configure CAC based on the number of multicast group memberships.

    • Configure the maximum number of multicast group memberships globally.

      1. Run the system-view command to enter the system view.

      2. Run the igmp-snooping max-user max-user command to configure the maximum number of global multicast group memberships.

        By default, the maximum number of multicast group memberships is not configured.

    • Configure the maximum number of multicast group memberships for a VAP.

      1. Run the system-view command to enter the system view.

      2. Run the wlan command to enter the WLAN view.

      3. Run the traffic-profile name profile-name command to enter the traffic profile view.

        By default, the system provides the traffic profile default.

      4. Run the igmp-snooping max-user max-user command to configure the maximum number of multicast group memberships for a VAP.

        By default, the maximum number of multicast group memberships is not configured for a VAP.

      5. Run the quit command to return to the WLAN view.

      6. Run the vap-profile name profile-name command to enter the VAP profile view.

      7. Run the traffic-profile profile-name command to bind the traffic profile to the VAP profile.

        By default, the traffic profile default is bound to a VAP profile.

Checking the Configuration

  • Run the display traffic-profile { all | name profile-name } command to check the multicast CAC configuration in the traffic profile.
