The forwarding database (FDB) contains information that maps the media access control (MAC) address of each 
known device to the GbE2 Interconnect Switch port where the device address was learned. The FDB also shows 
which other ports have seen frames destined for a particular MAC address. 
 
NOTE:  
The master forwarding database supports up to 16K MAC address entries on the management 
processor (MP) per GbE2 Interconnect Switch.

An address that is in the forwarding (FWD) state indicates that the GbE2 Interconnect Switch has learned it. When in 
the trunking (TRK) state, the port field represents the trunk group number. If the state for the port is listed as unknown
