338 CHAPTER 12: USING SYSTEM MANAGEMENT COMMANDS
Description
Use the mac-address timer command to configure the aging time of the Layer-2
dynamic address table entry. Use the
undo mac-address timer command to
restore the default value.
Setting the aging time on the switch to be too long or too short will cause the
switch to broadcast data packets without MAC addresses, this will affect the
operational performance of the switch.
If the aging time is set too long, the switch will store out-of-date MAC address
tables. This will consume MAC address table resources and the switch will not be
able to update MAC address table according to the network change.
If aging time is set too short, the switch may delete valid MAC address table
entries.
Example
Configure the entry aging time of Layer-2 dynamic address table to be 500
seconds.
