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.
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.
• IGMP filtering and throttling only applies to dynamically learned multicast
groups, it does not apply to statically configured groups.
