no-aging: Sets dynamic MAC address entries not to age.
Usage guidelines
Follow these guidelines to set the aging timer:
A long aging interval might cause the MAC address table to retain outdated entries and fail to
•
accommodate the latest network changes.
A short aging interval might result in removal of valid entries and unnecessary broadcasts that
•
affect the performance of the device.
Examples
# Set the aging timer for dynamic MAC address entries to 500 seconds.
