ip igmp snooping filter(interface)
Description
The ip igmp snooping filter command is used to configure Port Filter. To return
to the default configuration, please use no igmp snooping filter command.
When the switch receives IGMP report message, it examines the multicast
filtering IP ID configured on the access port to determine if the port can join the
multicast group. If the multicast IP is not filtered, the switch will add the port to
the forward port list of the multicast group. Otherwise, the switch will drop the
IGMP report message. In that way, you can control the multicast groups that
users can access.
