View the MFDB Table

The Layer 2 Multicast Forwarding Database (MFDB) holds the port membership information
for all active multicast address entries. The key for an entry consists of a VLAN ID and MAC
address pair. Entries can contain data for more than one protocol.

When the switch receives a packet with a destination multicast MAC address, this address is
combined with the VLAN ID, and the switch performs a search in the MFDB. If no match is
found, the packet is either flooded to all ports in the VLAN or discarded, depending on the
switch configuration. If a match is found, the packet is forwarded only to the ports that are
members of that multicast group per the specific VLAN ID.

To view the MFDB Table:

1.

Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.

2.

Launch a web browser.

3.

In the address field of your web browser, enter the IP address of the switch.
