Field Description
•
Length error frames—Frames whose 802.3 length fields did not
accord with the actual frame length (46 bytes to 1500 bytes).
- ignored
Number of inbound packets dropped because the receive buffer of the
port ran low.
- parity errors
Total number of frames with parity errors.
Output (total): 0 packets, 0 bytes
0 unicasts, 0 broadcasts, 0
multicasts, 0 pauses
Outbound traffic statistics (in packets and bytes) for the port. All
outbound normal and abnormal packets, and pause frames were
counted.
Output (normal): 0 packets, - bytes
0 unicasts, 0 broadcasts, 0
multicasts, 0 pauses
Outbound normal traffic and pause frame statistics (in packets and
bytes) for the port.
output errors
Outbound error packet statistics.
- underruns
Number of packet drops because the output rate of the port exceeded
the output queuing capability. This is a low probability hardware
anomaly.
- buffer failures
Number of packets dropped because the transmit buffer of the port ran
low.
aborts
Number of packets that failed to be transmitted, for example, because
of Ethernet collisions.
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.
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 Description
UP
The interface is physically up.
DOWN
The interface is physically down because no physical connection exists. The
possibly reason is 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.
