IGMP Filtering and Throttling
23
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.
Syntax

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)#
permit, deny
This command sets the access mode for an IGMP filter profile. Use the no form to delete a profile
number.
Syntax
{permit | deny}
