IGMP Filtering and Throttling
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.
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 Mode
Global Configuration
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.
