FDB Information
The forwarding database (FDB) contains information that maps the media access control
(MAC) address of each known device to the 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 MP
per switch.
dump
Dumps all switch information available from the Layer 2 menu (10K or more, depending on your
configuration).
If you want to capture dump data to a file, set your communication software on your workstation to
capture session data prior to issuing the dump commands.
[Forwarding Database Menu]
