Forwarding Database Information
To display the following form, select
Layer 2 > FDB.
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 8K MAC address entries on the MP per
switch.
The following table describes the Forwarding Database Information controls:
