R2511-HP MSR Router Series IP Multicast Command Reference(V5)

Usage guidelines
For a device that supports both IGMP snooping and IGMP, you can also use the group-policy
(IGMP-snooping view) command to control the multicast groups that hosts in a VLAN can join, achieving
the same result as igmp group-policy. If you have configured a multicast group filter on a VLAN interface
to control the multicast groups that the hosts on the interface can join, HP recommends you to configure
the same multicast group filter in the corresponding VLAN.
Examples
# Configure an ACL rule so that hosts on Ethernet 1/1 can join multicast group 225.1.1.1 only.
<Sysname> system-view
[Sysname] acl number 2005
[Sysname-acl-basic-2005] rule permit source 225.1.1.1 0
[Sysname-acl-basic-2005] quit
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] igmp group-policy 2005
