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.”
If the state for the port is listed as an interface (IF), the MAC address is for a standard VRRP
virtual router.
Clearing Entries from the Forwarding Database
To delete a MAC address from the forwarding database (FDB) or to clear the entire FDB, refer
to “Forwarding Database Maintenance” on page 343.
