Global Aging Time: 300
Vlan Aging Time
---- ----------
10 1000
Note:
the above command sets the aging-time of a dynamically learned MAC address through VLAN 10. If any mac-address learned from VLAN 10 is inactive for longer than 1000 seconds, it will be flushed out of the mac-address-table. By default, an inactive MAC address expires within 300 seconds.
