Show All FDB Information

An address that is in the forwarding (FWD) state, means that it has been learned by the switch.

When in the trunking (TRK) state, the port field represents the trunk group number. If the state

for the port is listed as unknown (UNK), the MAC address has not yet been learned by the

switch, but has only been seen as a destination address. When an address is in the unknown

state, no outbound port is indicated, although ports which reference the address as a destination

will be listed under “Reference ports.”
