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. This configuration takes effect only on the IPv6 multicast groups that the port joins dynamically.

If the number of IPv6 multicast groups on a port exceeds the limit, the system removes all the forwarding entries related to that port. In this case, 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. When the number of IPv6 multicast groups on the port reaches the limit, the port automatically drops MLD reports for new IPv6 multicast groups.
