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

394
If you do not specify any VLAN when using this command in port group view, the command takes effect
on all the ports in this group. If you specify one or multiple VLANs, the command takes effect only on
those ports in this group that belong to the specified VLANs.
If the specified ACL does not exist or the ACL rule is null, all IPv6 multicast groups are filtered out.
You can configure different IPv6 ACL rules for each port in different VLANs. For a given VLAN, a newly
configured IPv6 ACL rule overrides the existing one.
Examples
# Apply ACL 2000 as an IPv6 multicast group filter so that hosts on Ethernet 1/1 in VLAN 2 can join
FF03::101 only.
