Field - buffer failures aborts deferred collisions late collisions lost carrier - no carrier Description Number of packets dropped because the transmit buffer of the interface ran low. Number of packets that failed to be transmitted, for example, because of Ethernet collisions. Number of frames that the interface deferred to transmit because of detected collisions. Number of frames that the interface stopped transmitting because Ethernet collisions were detected during transmission. Number of frames that the interface deferred to transmit after transmitting their first 512 bits, because of detected collisions. Number of carrier losses during transmission. This counter applies to serial WAN interfaces. Number of times that the port failed to detect the carrier when attempting to send frames. This counter applies to serial WAN interfaces. NOTE: If an output field is not available, a hyphen (-) is displayed. Table 4 Description on the possible physical states of a Ethernet interface Field UP DOWN DOWN ( Administratively ) DOWN ( Link-Aggregation interface down ) DOWN ( OAM connection failure ) DOWN ( DLDP connection failure ) DOWN ( Loopback detection-protected ) Description The interface is physically up. The interface is physically down, because no physical connection exists. Possible reason: The network cable is disconnected or faulty. The interface is physically down, because it was shut down with the shutdown command. To restore its physical state, use the undo shutdown command. The interface is physically down, because the aggregate interface corresponding to the aggregation group to which it belongs was shut down with the shutdown command. The interface is physically down, because an OAM connection fails to be established on it or the OAM connection is disconnected. The interface is physically down, because a DLDP connection fails to be established on it or the DLDP connection is disconnected. The interface is shut down, because a loop is detected on it. DOWN ( BPDU-protected ) The interface is shut down by the BPDU guard function. DOWN ( Monitor-Link uplink The interface is physically down, because the uplink of the monitor link group down ) to which it belongs is down. # Display brief information about all interfaces. display interface brief The brief information of interface(s) under route mode: Link: ADM - administratively down; Stby - standby 10

interface ran low.
aborts
Number of packets that failed to be transmitted, for example, because
of Ethernet collisions.
deferred
Number of frames that the interface deferred to transmit because of
detected collisions.
collisions
Number of frames that the interface stopped transmitting because
Ethernet collisions were detected during transmission.
late collisions
Number of frames that the interface deferred to transmit after
transmitting their first 512 bits, because of detected collisions.
lost carrier
Number of carrier losses during transmission. This counter applies to
serial WAN interfaces.
- no carrier
Number of times that the port failed to detect the carrier when
attempting to send frames. This counter applies to serial WAN

Description on the possible physical states of a Ethernet interface
Field
Description
UP
The interface is physically up.
DOWN
The interface is physically down, because no physical connection exists.
Possible reason: The network cable is disconnected or faulty.
DOWN ( Administratively )
The interface is physically down, because it was shut down with the
shutdown
command. To restore its physical state, use the
undo shutdown
command.
DOWN ( Link-Aggregation
interface down )
The interface is physically down, because the aggregate interface
corresponding to the aggregation group to which it belongs was shut down
with the
shutdown
command.
DOWN ( OAM connection
failure )
The interface is physically down, because an OAM connection fails to be
established on it or the OAM connection is disconnected.
DOWN ( DLDP connection
failure )
The interface is physically down, because a DLDP connection fails to be
established on it or the DLDP connection is disconnected.
DOWN ( Loopback
detection-protected )
The interface is shut down, because a loop is detected on it.
DOWN ( BPDU-protected )
The interface is shut down by the BPDU guard function.
DOWN ( Monitor-Link uplink
down )
The interface is physically down, because the uplink of the monitor link group
to which it belongs is down.
