1.2.4 Configuring IGMP Snooping Filtering ACL
You can configure multicast filtering ACLs globally or on the switch ports connected to
user ends so as to use the IGMP Snooping filter function to limit the multicast streams
that the users can access. With this function, you can treat different VoD users in
different ways by allowing them to access the multicast streams in different multicast
groups.
In practice, when a user orders a multicast program, an IGMP report message is
generated. When the message arrives at the switch, the switch examines the multicast
filtering ACL configured on the access port to determine if the port can join the
corresponding multicast group or not. If yes, it adds the port to the forward port list of
the multicast group. If not, it drops the IGMP report message and does not forward the
corresponding data stream to the port. In this way, you can control the multicast
streams that users can access.
