372 Configuring Switching Information
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 destination MAC address. By limiting multicasts 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.
