The value is in the range of 10 to 1000000 seconds. 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 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guidelines to set the aging timer appropriately: • A long aging interval may cause the MAC address table to retain outdated entries and fail to accommodate the latest network changes.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 the performance of the switch. Examples # Set the aging timer for dynamic MAC address entries to 500 seconds. system-view [Sysname] mac-address timer aging 500 59
