Enter system view. system-view N/A2. Enable global MAC addresslearning. mac-address mac-learning enable By default, global MAC addresslearning is enabled.3. Enter VLAN view. vlan vlan-id N/A4. Disable MAC addresslearning on the VLAN.undo mac-address mac-learningenableBy default, MAC address learningon the VLAN is enabled.Configuring the aging timer for dynamic MACaddress entriesFor security and efficient use of table space, the MAC address table uses an aging timer for eachdynamic MAC address entry. If a dynamic MAC address entry is not updated before the aging timerexpires, the device deletes the entry. This aging mechanism ensures that the MAC address table canpromptly update to accommodate latest network topology changes.A stable network requires a longer aging interval, and an unstable network requires a shorter aginginterval.
