Setting the maximum number of multicast groups on a port

You can set the maximum number of multicast groups on a port to regulate the port traffic. This configuration takes effect only on the multicast groups that a port joins dynamically.

If the number of multicast groups on a port exceeds the limit, the system removes all the forwarding entries associated with the port. The receiver hosts attached to that port can join multicast groups again before the number of multicast groups on the port reaches the limit. When the number of multicast groups on the port reaches the limit, the port automatically drops IGMP reports for new groups.
