Setting the MAC Address Aging Time
The MAC address aging time is the time interval that a dynamic MAC address is allowed to
remain on the FDB table without sending any frame to the device. If the aging time expires,
the address of the network is removed from the FDB table. The following command sets the
MAC address aging time.
mac-address-table aging-time
The mac-address-table aging-time command, in Global Configuration mode, sets the MAC
address aging time value. The no form of this command turns the aging-time counter off. The
default aging-time value is 300 seconds.
NOTE
The actual aging time may take up to twice as long as the value that has been set, e.g.
if 300 seconds have been specified, the actual age-out period may take between 300
and 600 seconds.
Command Syntax
device-name(config)#mac-address-table aging-time <TIME>
device-name(config)#no mac-address-table aging-time
Argument Description
TIME The aging time value in seconds, in the range <10-816>
Example
The following example sets the MAC Address aging time to 800 seconds (13.3 minutes):
device-name(config)#mac-address-table aging-time 800
show mac-address-table aging-time
The show mac-address-table aging-time command, in Privileged (Enable) mode, displays
the MAC address aging time.
Command Syntax
device-name(config)#show mac-address-table aging-time
Example
