MLD 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 MLD filtering feature fulfills this requirement by
restricting access to specified multicast services on a switch port, and MLD
throttling limits the number of simultaneous multicast groups a port can join.
