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.

IGMP Filtering

Creating IGMP Profile
You can configure an IGMP profile for IGMP filtering in IGMP Profile Configuration mode.
The system prompt will be changed from SWITCH(config)# to SWITCH(config-igmp-
profile[N])#.
To create/modify an IGMP profile, use the following command.
Command
ip igmp profile <1-2147483647>
no ip igmp profile
<1-2147483647>
IGMP Group Range
To specify an IGMP group range to apply to IGMP filtering, use the following command.
Command
range A.B.C.D [ A.B.C.D ]
no range A.B.C.D [ A.B.C.D ]
A single IGMP group address is also possible.
IGMP Filtering Policy
To specify an action to permit or deny an access to an IGMP group range, use the follow-
ing command.
Command
{ permit | deny }
