The FDB chapter is intended to help you learn about forwarding databases, adding and displaying entries and entry types, managing the FDB, and MAC-based security. This chapter also provides information about MAC Address tracking.
The switch maintains a forwarding database (FDB) of all MAC addresses received on all of its ports. It uses the information in this database to decide whether a frame should be forwarded or filtered.
Note
See the Switch Engine 32.2 Command Reference Guide for details of the commands related to the FDB.
