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.
ip igmp filter (Global
Configuration)
This command globally enables IGMP filtering and throttling on the switch.
Use the no form to disable the feature.

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.
