show mac-lockdown-timeout fdb ports
Displays the MAC entries that are learned on the specified port or group of ports or for all ports on the switch along with the aging time of each port.
|all||Specifies all ports|
|port_list||Specifies one or more ports or slots and ports.|
If a port is down, the command displays all of the MAC entries that are maintained locally in the software.
The MAC entries learned on the specified port are displayed only if the MAC lock down timeout feature is enabled on the port. If you specify a port on which this feature is disabled, the MAC entries learned on that port are not displayed.
Mac—The MAC address that defines the entry.
Vlan—The VLAN name and ID for the entry.
Age—The age of the entry, in seconds.
Flags—Flags that define the type of entry:
F—Entry in the hardware FDB.
L—Entry in the software.
Port—The port on which the MAC address has been learned.
