Description
Physical connection state of the interface:

• ADM—The interface was shut down manually. You can bring up
the interface by using the undo shutdown command.
• Stby—The interface is a standby interface.
Data link layer protocol state:
• UP—The data link layer is up.
• DOWN—The data link layer is down.

its link is an on-demand link or not present at all.

the shutdown command. To restore the physical state of the
interface, use the undo shutdown command.
• Not connected—No physical connection exists (probably due to
network cable failures).
