The MAC address table on your device is available with an aging mechanism for
dynamic entries to prevent its resources from being exhausted. Set the aging timer
appropriately: a long aging interval may cause the MAC address table to retain
outdated entries and fail to accommodate latest network changes; a short interval
may result in removal of valid entries and hence unnecessary broadcasts which
may affect device performance.
Follow these steps to configure the MAC address aging timer:
To do...
