• Enable MLD snooping for the VLAN.
• Determine the ACL used as the IPv6 multicast group filter.
• Determine the maximum number of IPv6 multicast groups that a port can join.
Configuring an IPv6 multicast group filter
When you configure an IPv6 multicast group filter, follow these guidelines:
• This configuration takes effect for the IPv6 multicast groups that the port dynamically joins. If you
configure the port as a static member port for an IPv6 multicast group, this configuration does not
take effect for the IPv6 multicast group.
• You can configure an IPv6 multicast filter either for the current port in proper interface view or
globally for all ports in MLD-snooping view. If the configurations are made in both interface view
and MLD-snooping view, the configuration made in interface view takes priority.
Configuring an IPv6 multicast group filter globally
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MLD-snooping view. mld-snooping N/A
3. Configure an IPv6 multicast
group filter globally.
group-policy acl6-number [ vlan
vlan-list ]
By default, no IPv6 multicast group
filter is configured. A host can join
any valid IPv6 multicast group.
Configuring an IPv6 multicast group filter on a port
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
interface interface-type
interface-number
N/A
3. Configure an IPv6 multicast
group filter for the port.
mld-snooping group-policy
acl6-number [ vlan vlan-list ]
By default, no IPv6 multicast group
filter is configured for the port. The
hosts on this port can join any valid
IPv6 multicast group.
Configuring IPv6 multicast source port filtering
If the IPv6 multicast source port filtering feature is enabled on a port, the port can only connect to IPv6
multicast receivers rather than multicast sources. The port denies all IPv6 multicast data packets but it
permits multicast protocol packets.
If this feature is disabled, you can connect the port to either multicast sources or IPv6 multicast receivers.
You can enable multicast source port filtering either for the specified ports in MLD-snooping view or for
the current port in interface view. The two configurations have the same have the same priority level.
