IGMP Filtering and Throttling Commands

In certain switch applications, the administrator may want to control the multicast
services that are available to end users. For example, an IP/TV service based on a
specific subscription plan. The IGMP filtering feature fulfills this requirement by
restricting access to specified multicast services on a switch port, and IGMP
throttling limits the number of simultaneous multicast groups a port can join.
Command
ip igmp filter
ip igmp profile
permit, deny
range
ip igmp filter
ip igmp max-groups
ip igmp max-groups action Sets the IGMP throttling action for an interface
show ip igmp filter
show ip igmp profile
show ip igmp throttle
interface

ip igmp filter (Global Configuration)

This command globally enables IGMP filtering and throttling on the switch. Use the
no form to disable the feature.
Syntax
[no] ip igmp filter
Default Setting
Disabled

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.
