HROTTLING
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.
