IGMP Filtering and Throttling
IGMP filtering and throttling control the distribution of multicast services on each port.
IGMP filtering controls which multicast groups a host on a port can join by associating an
IGMP profile that contains one or more IGMP groups and specifies whether an access to
the group is permitted or denied with a port. For this operation, configuring the IGMP pro-
file is needed before configuring the IGMP filtering. IGMP throttling limits the maximum
number of IGMP groups that a host on a port can join.
Note that both IGMP filtering and throttling control only membership reports (join mes-
sages) from a host, and do not control multicast streams.
