Adding an entry to the forwarding database
To add an entry to the forwarding database, use the following command:
set fdb {perm | static} mac-addr port port-list vlan vlan-id [tag tag-value]
To add a permanent entry for MAC address 00:bb:cc:dd:ee:ff on ports 3 and 5 in VLAN blue, type the
following command:
WSS# set fdb perm 00:bb:cc:dd:ee:ff port 3,5 vlan blue
success: change accepted.
To add a static entry for MAC address 00:2b:3c:4d:5e:6f on port 1 in the default VLAN, type the following
command:
WSS# set fdb static 00:2b:3c:4d:5e:6f port 1 vlan default
success: change accepted.
Removing entries from the forwarding database
To remove an entry from the forwarding database, use the following command:
clear fdb {perm | static | dynamic | port port-list} [vlan vlan-id] [tag tag-value]
To clear all dynamic forwarding database entries that match all VLANs, type the following command:
WSS# clear fdb dynamic
success: change accepted.
To clear all dynamic forwarding database entries that match ports 3 and 5, type the following command:
WSS# clear fdb port 3,5
success: change accepted.
Configuring the aging timeout period
The aging timeout period specifies how long a dynamic entry can remain unused before the software removes
the entry from the database.
You can change the aging timeout period on an individual VLAN basis. You can change the timeout period to
a value from 0 through 1,000,000 seconds. The default aging timeout period is 300 seconds (5 minutes). If you
change the timeout period to 0, aging is disabled.
Displaying the aging timeout period
To display the current setting of the aging timeout period, use the following command:
show fdb agingtime [vlan vlan-id]
