4.8.4 IGMP Snooping Port Group Filtering
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.
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
