Parameters

to 3999. Hosts can join only IPv6 multicast groups that the ACL permits. If the ACL does not exist or
does not have valid rules, hosts cannot join IPv6 multicast groups.
vlan vlan-list
VLAN by its ID or a range of VLANs in the form of
ID is in the range of 1 to 4094. If you do not specify a VLAN, this command takes effect for all VLANs.
Usage guidelines
An IPv6 multicast group policy filters MLD reports to control the IPv6 multicast groups that hosts can
join.
This command does not take effect on static member ports, because static member ports do not
send MLD reports.
You can configure an IPv6 multicast group policy globally for all ports in MLD-snooping view or for a
port in interface view. For a port, the port-specific configuration takes priority over the global
configuration.
When you configure a rule in the IPv6 ACL, follow these restrictions and guidelines:
•
For the rule to take effect, do not specify the
•
In a basic ACL, the
multicast group address.
•
In an advanced ACL, the
IPv6 multicast source address. The

You can configure different ACLs for all ports in different VLANs. If you configure multiple ACLs for all
ports in the same VLAN, the most recent configuration takes effect.
