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
