2-­‐11.1.3 Port Filtering Profile
The section describes how to set IGMP Port Group Filtering. With the IGMP filtering feature, a user
can exert this type of control. In some network Application environments, for example, in
metropolitan or multiple-­‐dwelling unit (MDU) installations, a user might want to control the multicast
groups to which a user on a switch port can belong. It allows the user to control the distribution of
multicast services, such as IP/TV, based on some type of subscription or service plan.
With this feature, you can filter multicast joins on a per-­‐port basis by configuring IP multicast profiles
and associating them with individual switch ports. An IGMP profile can contain one or more multicast
groups and specifies whether access to the group is permitted or denied. If an IGMP profile denying
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.
