Description
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—Link is up.
DOWN—Link is down physically.
ADM—Link has been shut down administratively. To recover its physical
state, perform the undo shutdown command.
Stby—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 negotiated automatically, its speed attribute
includes the auto negotiation flag, letter a in parentheses.
If the duplex mode of an interface is negotiated automatically, 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.
Causes for the physical state of an interface to be DOWN. For more
information, see Table 7.
Description
No physical connection exists (possibly because the network cable is
disconnected or faulty).
