5.25.4 IGMP Filtering and Throttling Commands
In certain switch applications, the administrator may want to control the multicast services that are available to end users. For
Example, an IP/TV service based on a specific subscription plan. The IGMP filtering feature fulfills this requirement by
restricting access to specified multicast services on a switch port, and IGMP throttling limits the number of simultaneous
multicast groups a port can join.

Command Usage
IGMP filtering enables you to assign a profile to a switch port that specifies multicast groups that are permitted or denied
on the port. An IGMP filter profile can contain one or more, or a range of multicast addresses; but only one profile can be
assigned to a port. When enabled, IGMP join reports received on the port are checked against the filter profile. If a
requested multicast group is permitted, the IGMP join report is forwarded as normal. If a requested multicast group is
denied, the IGMP join report is dropped.
IGMP filtering and throttling only applies to dynamically learned multicast groups, it does not apply to statically configured
groups.
