Field Description
ignored
Number of inbound frames dropped because the receive buffer of the
port ran low.
- parity errors
Total number of frames with parity errors.
Output (total): 1502 packets,
138924 bytes
- unicasts, 2 broadcasts, 406
multicasts, 0 pauses
Outbound traffic statistics (in packets and bytes) for the port. All
outbound normal and abnormal packets (including unicast, broadcast,
and multicast), and pause frames were counted.
Output (normal): - packets, - bytes
1094 unicasts, - broadcasts, -
multicasts, - pauses
Outbound normal traffic (including unicast, broadcast, and multicast)
and pause frame statistics (in packets and bytes) for the interface.
output errors
Statistics of error packets sent out of the interface.
- underruns
Number of packets dropped because the output rate of the interface
exceeded the output queuing capability. This is a low-probability
hardware anomaly.
- buffer failures
Number of packets dropped because the transmit buffer of the
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
interfaces.
NOTE:
If an output field is not available, a hyphen (-) is displayed.
Table 2
Description on the possible physical states of a Layer 2 Ethernet interface
Field Description
UP
The interface is physically up.
DOWN
The interface is physically down because no physical connection exists
(possibly because the network cable is disconnected or faulty).
DOWN ( Administratively )
The interface 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 down because the aggregate interface corresponding to the
aggregation group to which it belongs was shut down with the
shutdown
command.
