Description
Use mac-address timer to configure the aging timer for dynamic MAC address entries.
Use undo mac-address timer to restore the default.
By default, the aging timer is 300 seconds.
Follow these guidelines to set the aging timer appropriately:
A long aging interval may cause the MAC address table to retain outdated entries and fail to accommodate the latest network changes.
A short aging interval may result in removal of valid entries and unnecessary broadcasts that may affect the performance of the switch.
