Field Descri
p
tion
Link: ADM - administratively down; Stby -
standby
Link layer state of the interface:
• ADM—The interface was shut down by the network
administrator. To recover its physical layer state, perform the
undo shutdown command.
• Stby—The interface is a standby interface. You can use the
display interface-backup state command to check the
corresponding primary interface.
Protocol: (s) - spoofing
If the protocol attribute of an interface includes the spoofing flag
(an s in parentheses), the data link layer protocol state of the
interface is shown as UP. However, its link is an on-demand link
or not present.
Interface Abbreviation of the interface name.
Link
Physical connection state of the interface:
• UP—The interface is physically connected.
• DOWN—The interface is physically disconnected.
• ADM—The interface is shut down manually. You can bring
up the interface with command undo shutdown.
• Stby—The interface is a standby interface.
Protocol
Data link layer protocol state of the interface:
• UP—The data link layer is up.
• DOWN—The data link layer is down.
• UP(s)—The data link layer protocol state of the interface is
up, but its link is an on-demand link or not present.
Main IP Primary IP address of the interface.
Description
Description for the interface configured with command
description.
The display interface brief command displays the following:
• The first 27 characters when you do not specify the
description keyword.
• The entire description when you specify the description
keyword.
Cause
Cause for a DOWN physical link:
• Administratively—The link was shut down with the
shutdown command. To restore the physical state of the
interface, use the undo shutdown command.
• Not connected—No physical connection exists (typically
due to network wire failures).
interface atm
Use interface atm to enter ATM interface view or ATM subinterface view. Before you enter ATM
subinterface view, the command creates the subinterface and enters its view if the specified subinterface
does not exist.
Use undo interface atm to remove an ATM subinterface.
