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.
After configuring multicast profiles, you can assign them to interfaces on the industrial
managed switch. The multicast throttling number can also be set to limit the number of
multicast groups an interface can join at the same time.

Multicast filter
In certain switch applications, the administrator may want to control the multicast
services available to end users. For example, an IP/TV service is based on a specific
subscription plan. The multicast filtering feature fulfills this requirement by restricting
access to specified multicast services on a switch port.
Multicast filtering enables you to assign a profile to a switch port that specifies multicast
groups that are permitted or denied on the port. A multicast filter profile can contain one
