To configure entries in the FDB, use the commands listed in Table 6-1.
This example adds a permanent entry to the FDB:

The permanent entry has the following characteristics:
MAC address is 02608c123456
VLAN name is marketing
Port number for this device is 4
To display FDB entries, use the command:
show fdb {all | <mac_address> | vlan <name> | <portlist> |
permanent}
Where:
all — displays all FDB entries
mac_address — displays the entry for a particular MAC address
vlan <name> — displays the entries for a VLAN
Description
Allows you to create a permanent FDB entry. Specify the
following:
mac_address — Device MAC address, using colon
separated bytes
name — VLAN associated with MAC address
portlist — Port number associated with MAC address
If more than one port number is associated with a
permanent MAC entry, packets will be multicast to the
multiple destinations.

15 through 1,000,000 seconds. The default value is 1800
seconds. A value of 0 indicates that the entry should
never be aged out.
