Description
The command displays brief information about Layer 3 interfaces.
Link layer state of the interface:
•
ADM—The interface has been shut down by the network administrator. To
recover its physical layer state, perform the undo shutdown command.
•
Stby—The interface is a standby interface.
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 name.
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, perform the undo shutdown command.
•
Stby—The interface is a standby interface.
Protocol connection state of the interface, which can be UP, DOWN, or UP(s).
Brief information about Layer 2 interfaces.
If the speed of an interface is automatically negotiated, its speed attribute
includes the auto negotiation flag, letter a in parentheses.
If the duplex mode of an interface is automatically negotiated, its duplex mode
attribute includes the following options:
•
(a)/A—Auto negotiation
•
H—Half negotiation
•
F—Full negotiation
Link type options for Ethernet interfaces.
Interface rate, in bps.
Duplex mode of the interface:
•
A—Auto-negotiation
•
F—Full duplex
•
F(a)—Auto-negotiated full duplex
•
H—Half duplex
•
H(a)—Auto-negotiated half duplex
Link type of the interface:
•
A—Access
•
H—Hybrid
•
T—Trunk
Port VLAN ID of the interface.
