Field Description
Link: ADM -
administratively down;
Stby - standby
Link layer state of the interface:
•
ADM
—The interface has been shut down by the network administrator. To
recover its physical layer state, use the
undo shutdown
command.
•
Stby
—The interface is a standby interface. You can use the
display standby
state
command to check the corresponding primary interface.
Protocol: (s) - spoofing
The protocol attribute of an interface includes the spoofing flag (a letter
s
in
parentheses) when the following conditions exist:
•
The network layer protocol state of the interface is shown as UP.
•
Its link is an on-demand link or not present.
This attribute is typical of interface Null 0 and loopback interfaces.
Interface Interface
name.
Link
Physical link state of the interface:
•
UP
—The link is up.
•
DOWN
—The link is physically down.
•
ADM
—The link has been administratively shut down. To recover its physical
state, use the
undo shutdown
command.
•
Stby
—The interface is a standby interface.

Brief information about Layer 2 interfaces.
Speed or Duplex: (a)/A -
auto; H - half; F - full
If the speed of an interface is automatically negotiated, its speed attribute
includes the autonegotiation flag, the letter
a
in parentheses.
If the duplex mode of an interface is automatically negotiated, its duplex mode
attribute includes the following options:
•
(a)/A
—Autonegotiation.
•
H
—Half negotiation.
•
F
—Full negotiation.
Type: A - access; T - trunk;
H - hybrid
Link type options for Ethernet interfaces.
Speed
Interface rate, in bps.
Duplex
Duplex mode of the interface:
•
A
—Autonegotiation.
•
F
—Full duplex.
•
F(a)
—Auto-negotiated full duplex.
•
H
—Half duplex.
•
H(a)
—Auto-negotiated half duplex.
