Field Description
aborts
The total number of incoming illegal packets, including:
z
Fragments: CRC error frames of less than 64 bytes
(integer or non-integer).
z
Jabber frames: CRC error frames of more than
1518 bytes if untagged or 1522 bytes if tagged
(integer or non-integer).
z
Symbol error frames: frames with at least one
symbol error.
z
Unknown operator frames: MAC control frames that
are not Pause frames
z
Length error frames: frames whose actual length
(46-1500 bytes) is inconsistent with the length field
in the 802.3 header.
ignored
The number of packets dropped due to insufficient
receive buffer on the port
- parity errors The number of incoming parity error frames
Output(total): 0 packets, 0 bytes
0 broadcasts, 0 multicasts, 0
pauses
Count in packets and in bytes of total outgoing traffic on
the port, including normal packets, abnormal packets,
and normal Pause frames
The number of outgoing broadcast packets, the
number of outgoing multicast packets, and the number
of outgoing Pause frames on the port
Output(normal): - packets, - bytes
- broadcasts, - multicasts, - pauses
Count in packets and in bytes of outgoing normal
packets on the port, including outgoing normal packets
and normal Pause frames.
The number of normal outgoing broadcast packets, the
number of normal outgoing multicast packets, and the
number of normal outgoing Pause frames on the port.
A hyphen (-) indicates that the statistical item is not
supported.
output errors The total number of outgoing error frames
- underruns
The number of packets dropped because the
transmitting rate of the port exceeds the processing
capacity of the output queue, which is a rare hardware
error.
- buffer failures
The number of packets dropped due to insufficient
transmit buffer on the port
aborts
The number of transmission failures due to various
reasons, such as collisions
deferred
The number of first transmission attempts delayed
because of detection of collisions
collisions
The number of detected collisions
(Transmission of a frame will be aborted upon
detection of a collision.)
late collisions
The number of detected late collisions
(A late collision occurs if the transmission of a frame
defers due to detection of collision after its first 512 bits
have been transmitted.)
