3.5.3 IGMP Snooping Multicast Forwarding Table
The multicast forwarding table displays how packets that arrive with a multicast destination MAC address are
forwarded.
The destination MAC address is combined with the VLAN ID when a packet is sent into the switch. And the
multicast searching status and the multicast forwarding status are displayed in the multicast forwarding table. If
there is no match found, the packet is flooded to all interfaces in VLAN or discarded. It depends on the
configuration. If there is a match found, the packet is forwarded to the interfaces which are the members of the
multicast group.
