IGMP Filtering and Throttling
– 480 –
Command Usage
◆
IGMP filtering enables you to assign a profile to a switch port that specifies
multicast groups that are permitted or denied on the port. An IGMP filter profile
can contain one or more, or a range of multicast addresses; but only one profile
can be assigned to a port. When enabled, IGMP join reports received on the
port are checked against the filter profile. If a requested multicast group is
permitted, the IGMP join report is forwarded as normal. If a requested multicast
group is denied, the IGMP join report is dropped.
◆
IGMP filtering and throttling only applies to dynamically learned multicast
groups, it does not apply to statically configured groups.
◆
The IGMP filtering feature operates in the same manner when MVR is used to
forward multicast traffic.
Example
Console(config)#ip igmp filter
Console(config)#
ip igmp profile
This command creates an IGMP filter profile number and enters IGMP profile
configuration mode. Use the
no
form to delete a profile number.

Command Usage
A profile defines the multicast groups that a subscriber is permitted or denied to
join. The same profile can be applied to many interfaces, but only one profile can
be assigned to one interface. Each profile has only one access mode; either permit
or deny.
Example
Console(config)#ip igmp profile 19
Console(config-igmp-profile)#
