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.
Configuration restrictions and guidelines
When you set the maximum number of multicast groups on a port, follow these restrictions and guidelines:
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 related to that 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.
