An address that is in the forwarding (FWD) state indicates that the switch has learned it. When in the
trunking (TRK) state, the Trnk field displays 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.
Clearing entries from the forwarding database
To delete a static MAC address from the forwarding database (FDB), see the “Static FDB configuration”
section in the “Configuration Commands” chapter.
