Explanation of IGMP throttling (limiting the number of
streams for each subscriber)
In this example, switch 2’s configuration limits port 2 to six concurrent multicast groups. The
port has a throttling action of replace, meaning that any additional group replaces the oldest
group.
Consider switch 2 after a client on port 2 has joined six groups from 224.
