The system view is displayed.
Step 2 Run:
vlan vlan-id
The VLAN view is displayed.
Step 3 Run:
mld-snooping group-policy acl-number [ mld-version ]
A multicast group policy is configured.
By default, no multicast group policy is available in a VLAN. That is, hosts in a VLAN can join
any multicast group. MLDv1/v2 is used.
Only a basic or advanced ACL6 can be used. Before configuring a multicast group policy, ensure
that an ACL6 has been created and a rule has been defined. For details, see Configuring ACL6.

4.4.3 Checking the Configuration

Procedure
Step 1 Run the display mld-snooping [ vlan vlan-id ] [ configuration ] command to check the
configuration of MLD snooping in a VLAN.
Step 2 Run the display mld-snooping port-info [ vlan vlan-id [ group group-ipv6-address [ source-
address source-ipv6-address ] | verbose ] ] command to check the configuration of MLD
snooping on an interface.

4.5 Configuring Prompt Leave of Interfaces

This section describes how to configure prompt leave of interfaces in a VLAN.

4.5.1 Establishing the Configuration Task

Applicable Environment
If each interface in a VLAN is connected to only one multicast receiver, you can enable prompt
leave on the interfaces to save bandwidth.
Issue 01 (2011-07-15)
NOTE
l When a multicast policy is configured for a VLAN, the multicast policy does not take effect if the
ACL6 specified by the ACL number does not exist; therefore, the hosts in the VLAN can join any
multicast group.
l If you run the undo acl ipv6 command to delete the ACL6 used by the multicast policy, hosts in the
VLAN can join any multicast group.
l A multicast policy is invalid for static multicast entries.
