View and Search the Multicast Forwarding Database Table The smart switch uses the multicast forwarding database (MFDB) to determine how incoming packets with a multicast MAC address need to be forwarded to their destination. When a packet enters the switch, the destination MAC address is combined with the VLAN ID, and the smart switch searches the MFDB: • If the smart switch finds a match, the packet is forwarded only to the ports or LAGs that are members of the multicast group. • If the smart switch does not find a match, either it floods the packet to all ports in the VLAN, or it discards the packet, depending on the configuration. The MFDB contains all active multicast MAC addresses with their associated VLANs, ports, and forwarding ports. You can search the MFDB by MAC address.  To view the MFDB Table and search for an entry in the MFDB Table: 1. Switching > Multicast > IGMP Snooping > MFDB Table. Configure Multicast 112
