Command Usage
• IGMP filtering enables you to assign a profile to a switch port that
specifies multcast 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. Wh en
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)#
