2-9.3 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.
