4.7.6 Multicast Throttling Setting
Multicast throttling sets a maximum number of multicast groups that a port can join at the same time. When the
maximum number of groups is reached on a port, the switch can take one of two actions; either “deny” or “replace”. If
the action is set to deny, any new multicast join reports will be dropped. If the action is set to replace, the switch
randomly removes an existing group and replaces it with the new multicast group.
Once you have configured multicast profiles, you can assign them to interfaces on the Managed Switch. Also you can
set the multicast throttling number to limit the number of multicast groups an interface can join at the same time. The
MAX Group and Information screens in Figure 4-7-34 & Figure 4-7-35 appear.
