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.
