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 inhib-
ited by exactly one collision.
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 inter-
face is delayed because the medium was busy.
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 (exclud-
ing 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.
The total number of frames (bad, broadcast and multicast) received.
The total number of good frames received that were directed to the broadcast
address. Note that this does not include multicast packets.
The total number of good frames received that were directed to this multicast
address.
The number of CRC/alignment errors (FCS or alignment errors).
The total number of frames received that were less than 64 octets long (exclud-
ing framing bits, but including FCS octets) and were otherwise well formed.
The total number of frames received that were longer than 1518 octets (exclud-
ing framing bits, but including FCS octets) and were otherwise well formed.
