318 Configuring Switch Information

When IGMP Snooping is enabled globally, all IGMP packets are forwarded to the CPU. The CPU
analyzes the incoming packets and determines which ports want to join which Multicast groups,
which ports have Multicast routers generating IGMP queries, and which routing protocols are
forwarding packets and Multicast traffic.
Ports requesting to join a specific Multicast group issue an IGMP report specifying that the
Multicast group is accepting members. This creates the Multicast filtering database.
