Field Description
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 auto negotiation flag, letter
a
in parentheses or a capital
A
.
Letter
H
indicates the half duplex mode, and letter
F
indicates the full duplex
mode.
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 why the physical state of an interface is DOWN.
provides the
details.
Table 4
Causes why the physical state of an interface is DOWN
Field Description
Not connected
No physical connection exists (possibly because the network cable is
disconnected or faulty).
Administratively
The port was shut down with the
shutdown
command. To restore the physical
state of the interface, use the
undo shutdown
command.
Link-Aggregation interface
down
The aggregate interface corresponding to the aggregation group to which the
current interface belongs was shut down with the
shutdown
command.
OAM connection failure
OAM connection fails (possibly because the connection fails to be established
or the current connection is disconnected).
DLDP connection failure
DLDP connection fails (possibly because the connection fails to be established
or the current connection is disconnected).
Loopback detection-protected The interface is shut down because a loop is detected on it.
BPDU-protected
The interface is shut down by the BPDU guard function.
Monitor-Link uplink down
The uplink of the current monitor link group to which the current interface
belongs is down.
