no-aging
: Sets dynamic MAC address entries not to age.
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 for dynamic MAC address entries 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A long aging interval may cause the MAC address table to retain outdated entries and fail to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 device performance.
Examples
# Set the aging timer for dynamic MAC address entries to 500 seconds.
