Parameters

aging seconds: Specifies an aging timer for dynamic MAC address entries, in seconds. The value range for the seconds argument is 10 to 1000000.

no-aging: Configures dynamic MAC address entries not to age.

Usage guidelines

To set the aging timer appropriately, follow these guidelines:

• A long aging interval causes the MAC address table to retain outdated entries and fail to accommodate the most recent network changes.

• A short aging interval results in removal of valid entries. Then, unnecessary broadcast packets appear and affect device performance.

Examples

# Set the aging time to 500 seconds for dynamic MAC address entries.
