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.
