Managing the Layer 2 Forwarding Database 99
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
display fdb agingtime [vlan vlan-id]
For example, to display the aging timeout period for all configured
VLANs, type the following command:
WX1200# display fdb agingtime
VLAN 2 aging time = 300 sec
VLAN 1 aging time = 300 sec
Changing the Aging Timeout Period
To change the aging timeout period, use the following command:
set fdb agingtime vlan-id age seconds
For example, to set the aging timeout period for VLAN 2 to 600 seconds,
type the following command:
WX1200# set fdb agingtime 2 age 600
success: change accepted.
