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 o r m ultiple-­‐dwelling u nit ( MDU) i nstallations, a u ser m ight w ant t o c ontrol t he m ulticast
groups to which a user on a switch port can belong. It allows the user to control the distribution of
multicast s ervices, s uch a s I P/TV, b ased o n s ome t ype o f s ubscription o r s ervice p lan.
With t his f eature, y ou c an f ilter multicast j oins o n a p er-­‐port b asis b y c onfiguring I P m ulticast p rofiles

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

IGMP filtering controls only IGMP membership join reports and has no relationship to the function
