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A long aging interval may cause the MAC address table to retain outdated entries and fail to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.
