IPTV Application: IGMP Filtering

This feature allows the administrator to control the distribution of multicast services, such as IP/TV, based on some type of subscription or service plan.

With IGMP filtering feature, you can filter multicast joins on a per-port basis by configuring IP multicast profiles and associating them with specified switch ports. An IGMP profile can contain one or more multicast groups and specifies whether access to the group is permitted or refuse. If an IGMP profile refused access to a multicast group is applied to a switch port, the IGMP join report requesting the stream of IP multicast traffic is dropped, and the port is not allowed to receive IP multicast traffic from that group. If the filtering action permits access to the multicast group, the IGMP report from the port is forwarded for normal processing.

IGMP filtering controls only IGMP membership join reports and has no relationship to the function that directs the forwarding of IP multicast traffic.
