Filtering IGMP Traffic

Internet Group Management Protocol (IGMP) filtering allows an administrator to configure IP multicast
group profiles consisting of one or more ranges of IP multicast addresses. The administrator associates
these profiles with a filtering and monitoring action. These actions apply to IGMP packets, are
configured on a per-switch-port basis, and are available to all VLANs that are associated with the
physical port.
