2-12.1.3 Port Filtering Profile
The section describes how to set the IGMP Port Group Filtering? With the IGMP
filtering feature, a user can exert this type of control. In some network Application
environments, as like the 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.
