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 isinhibited
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 particularinterface
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.
The total number of frames (bad, broadcast and multicast) received.
