Field Description
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:
• 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, including UP, DOWN, and UP(s).
The brief information of
interface(s) under bridge
mode:
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 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
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—Auto-negotiation
• F—Full duplex
• F(a)—Auto-negotiated full duplex
• H—Half duplex
• H(a)—Auto-negotiated half duplex
Type
Link type of the interface:
• A—Access
• H—Hybrid
• T—Trunk
PVID Default VLAN ID of the interface.
Cause
Causes for the physical state of an interface to be DOWN. For more information,
see Table 6.

Field Description
Not connected
No physical connection exists (possibly because the network cable is
disconnected or faulty).
