Description
The number of outbound packets which were chosen to be discarded even
though no errors had been detected to prevent their being transmitted.
One possible reason for discarding such a packet could be to free up
buffer space.
The number of outbound packets that could not be transmitted because of
errors.
The number of alignment errors (missynchronized data packets).
The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
A count of frames received on a particular interface that are an integral
number of octets in length but do not pass the FCS check. This count does
not include frames received with frame-too-long or frame-too-short error.
A count of frames for which transmission on a particular interface fails due
to excessive collisions. This counter does not increment when the
interface is operating in full-duplex mode.
The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
A count of frames for which transmission on a particular interface fails due
to an internal MAC sublayer transmit error.
A count of successfully transmitted frames for which transmission is
inhibited by more than one collision.
The number of times that the carrier sense condition was lost or never
asserted when attempting to transmit a frame.
A count of times that the SQE TEST ERROR message is generated by the
PLS sublayer for a particular interface.
A count of frames received on a particular interface that exceed the
maximum permitted frame size.
A count of frames for which the first transmission attempt on a particular
interface is delayed because the medium was busy.
A count of frames for which reception on a particular interface fails due to
an internal MAC sublayer receive error.
The total number of events in which packets were dropped due to lack of
resources.
The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets), and had either an FCS
or alignment error.
Total number of bytes of data received on the network. This statistic can
be used as a reasonable indication of Ethernet utilization.
The best estimate of the total number of collisions on this Ethernet
segment.
