SUMMARY STEPS
1. configure terminal
2. mac-address-table aging-time <10-1000000>
3. end
DETAILED STEPS
Caution Cisco advises that you not change the aging timer, because the EtherSwitch HWIC could go out of
synchronization.
Verifying the Aging Time
Use the show mac-address-table aging-time command to verify the MAC address table aging timer, as
illustrated below:
Router # show mac-address-table aging-time
Mac address aging time 320
