Managing Multicast Support
The Layer 2 Multicast Forwarding Database is used by the switch to make forwarding decisions for
packets that arrive with a multicast dest ination MAC address. By limiting multi casts to only certain ports
in the switch, traffic is prevented from going to parts of the network where that traffic is unnecessary.
When a packet enters the switch, the destination MAC address is combined with the VLAN ID and a
search is performed in the Layer 2 Forwarding database. If no match is found, then the packet is either
flooded to all ports in the VLAN or discarded, depending on the switch configuration. If a match is
found, then the packet is forwarded only to the ports that are members of that multicast group.
