2.2.5 Configuring a Multicast Group Filter

On an IGMP Snooping-enabled switch, the configuration of a multicast group allows the
service provider to define restrictions on multicast programs available to different users.
In an actual application, when a user requests a multicast program, the user's host
initiates an IGMP report. Upon receiving this report message, the switch checks the
report against the ACL rule configured on the receiving port. If the receiving port can
join this multicast group, the switch adds this port to the IGMP Snooping multicast
group list; otherwise the switch drops this report message. Any multicast data that has
failed the ACL check will not be sent to this port. In this way, the service provider can
control the VOD programs provided for multicast users.
Make sure that an ACL rule has been configured before configuring this feature.
