2.2.3 Enabling IGMP Fast Leave
Normally, when receiving an IGMP Leave message, IGMP Snooping does not
immediately remove the port from the multicast group, but sends an IGMP
group-specific query message. If no response is received in a given period, it then
removes the port from the multicast group.
If IGMP fast leave processing is enabled, when receiving an IGMP Leave message,
IGMP Snooping immediately removes the port from the multicast group. When a port
has only one user, enabling IGMP fast leave processing on the port can save
bandwidth.

2.2.4 Configuring IGMP Snooping Filtering ACL
You can configure multicast filtering ACLs 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
