2.6 Configuring an IGMP Snooping Policy

2.6.1 Configuration Prerequisites

Before configuring an IGMP Snooping policy, complete the following task:
Enable IGMP Snooping in the VLAN or enable IGMP on the desired VLAN
interface
Before configuring an IGMP Snooping policy, prepare the following data:
ACL rule for multicast group filtering
The maximum number of multicast groups that can pass the ports

2.6.2 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 configured ACL rule. If the port on which the report was heard can
join this multicast group, the switch adds an entry for this port in the IGMP Snooping
forwarding table; 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.
