Command output description
Field Description
The brief information of
interface(s) under route
mode:
The command displays brief information about Layer 3 interfaces
Link: ADM -
administratively down;
Stby - standby
The interface has been shut down by the network administrator. To recover its
physical layer state, perform the
undo shutdown
command.
Stby
indicates that the current interface is a standby interface.
Protocol: (s) - spoofing
If the network layer protocol state of an interface is shown as UP, but its link is an
on-demand link or not present at all, its protocol attribute includes the spoofing
flag (an
s
in parentheses). This attribute is typical of interface Null 0 and the
loopback interfaces.
Interface Interface
name
Link
Physical link state of the interface, which can be:
•
UP—The link is up.
•
DOWN—The link is physically down.
•
ADM—The link has been administratively shut down. To recover its physical
state, perform the
undo shutdown
command.
•
Stby—The interface is a standby interface.
Protocol
Protocol connection state of the interface, which can be UP, DOWN, or UP(s).
