IPv6 multicast data for the
VLAN

Setting the maximum number of IPv6 multicast groups on a port

You can set the maximum number of IPv6 multicast groups on a port to regulate the port traffic.
When you set the maximum number of IPv6 multicast groups on a port, follow these guidelines:
• This configuration is effective 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 is not
effective for the multicast group.
If the number of IPv6 multicast groups on a port exceeds the limit, the system removes all the
•
forwarding entries related to that port from the MLD snooping forwarding table. The receiver hosts
attached to that port can join IPv6 multicast groups again before the number of IPv6 multicast
groups on the port reaches the limit.
To set the maximum number of IPv6 multicast groups on a port:
Step
1. Enter system view.
2. Enter Ethernet interface view
or aggregate interface view.
3. Set the maximum number of
IPv6 multicast groups on a
port.

Enabling the IPv6 multicast group replacement function

When the number of IPv6 multicast groups on a switch or a port exceeds the limit:
• If the IPv6 multicast group replacement is enabled, the switch or the port replaces an existing IPv6
multicast group with a newly joined IPv6 multicast group.
If the IPv6 multicast group replacement is disabled, the switch or the port discards MLD reports that
•
are used for joining a new IPv6 multicast group.
In some specific applications, such as channel switching, a newly joined IPv6 multicast group must
automatically replace an existing IPv6 multicast group. In this case, the function of IPv6 multicast group
replacement must also be enabled so a user can switch from the current IPv6 multicast group to a new
group.
When you enable the IPv6 multicast group replacement function, follow these guidelines
• This configuration is effective for the multicast groups that the port dynamically joins. If you
configure the port as a static member port for a multicast group, this configuration is not effective for
the multicast group.
