Configuring an aging time for learned security MAC address entries
By default, learned security MAC address entries will never be aged; they are deleted only when the
port security feature is disabled or the security mode is not autolearn any more.
You can configure an aging time for security MAC address entries. When the timer of an entry expires,
the entry is removed from the security MAC address table.
Follow these steps to configure an aging time for learned security MAC address entries:
To do...
Enter system view
Enable port security
Configure the aging time for
learned security MAC address
entries
Enter Ethernet port view
Set the maximum number of
MAC addresses allowed on the
port
Set the security mode of the port
to autolearn
After you execute the port-security timer autolearn command, you can display security MAC address
entries by the display mac-address security command. Though the aging time field displayed has a
value of "NOAGED", the aging of security MAC address entries is enabled already.
Use the command...
system-view
mac-address security mac-address
interface interface-type interface-number vlan
vlan-id
interface interface-type interface-number
mac-address security mac-address vlan

Use the command...
