Configuring a Multicast Group Policy

Configuring a Multicast Group Policy

Context

A multicast group policy determines the multicast groups that user hosts in a VLAN can join. The multicast group policy is valid for only dynamic multicast groups. Before configuring a multicast group policy, create an ACL6 and define rules. For details about ACL6 configuration, see "ACL Configuration" in CloudEngine 12800 and 12800E Series Switches Configuration Guide - Security.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Use either of the following methods to configure a multicast group policy.

    • Configure a multicast group policy in a VLAN.
      1. Run the vlan vlan-id command to enter the VLAN view.

      2. Run the mld snooping group-policy { acl6-number | acl6-name acl6-name } [ version number ] command to configure a multicast group policy in the VLAN.

    • Configure a multicast group policy on an interface.
      1. Run the interface interface-type interface-number command to enter the interface view.

      2. Run the mld snooping group-policy { acl6-number | acl6-name acl6-name } [ version number ] { vlan vlan-id1 [ to vlan-id2 ] &<1-10> } command to configure a multicast group policy on the interface.

    By default, user hosts in a VLAN can join any multicast group. If the MLD version is not specified for a multicast group policy, the switch applies the policy to all the received MLD messages regardless of their versions.

    If you configure multicast group policies for the same VLAN in the interface view and VLAN view, the system first uses the policy configured in the interface view and then the policy configured in the VLAN view to determine the groups that user hosts can join.

    NOTE:

    When an ACL6 to be referenced by a multicast group policy in a VLAN is configured, permit in the ACL6 is valid for all multicast groups. If the switch is configured to receive multicast data from a specified multicast group or some multicast groups only, use rule deny source any.

  3. Run commit

    The configuration is committed.
