H3C S7500E Series Command Reference

1-14
Field Description
deferred
Number of frames that the port deferred to transmit because of
detected collisions.
collisions
Number of frames that the port stopped transmitting because Ethernet
collisions were detected during transmission.
late collisions
Number of frames that the port 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
interfaces.
If an output field is not available, a hyphen (-) is displayed.
Table 1-6 Description on the possible physical states of an Ethernet interface
Field Description
UP The interface is physically up.
DOWN
The interface is physically down because no physical connection exists
(possibly reason: the network cable is disconnected or faulty).
DOWN ( Administratively )
The interface is physically down because it was brought 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 current 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 current 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.
