ifOutDiscards The number of outbound packets which were chosen to be
discarded even though no errors had been detectedto prevent
their being transmitted.
dot3statsAlignmentErrors Number of frames with an alignment error, i.e., the length is not
an integral number of octets and the frame cannot pass the Frame
Check Sequence (FCS) test
dot3StatsFCSErrors Number of frames with framecheck errors, i.e., there is an
integral number of octets, but an incorrect Frame Check
Sequence (FCS)
dot3StatsSingleCollisionFrames Number of successfully transmitted frames that had exactly one
collision
dot3StatsMutlipleCollisionFrame Number of successfully transmitted frames that had multiple
collisions
dot3StatsDeferredTransmissions Number of times the first transmission was delayed because the
medium was busy
dot3StatsLateCollision Number of times that a collision was detected later than 64 octets
into the transmission (also added into collision count)
dot3StatsExcessiveCollision Number of frames where transmissions failed because of
excessive collisions
dot3StatsCarrierSenseErrors The number of transmission errors on a particular interface that
are not otherwise counted.
dot3StatsSQETestErrors A count of times that the SQE TEST ERROR message is
generated by the PLS sublayer for a particular interface.
etherStatsJabbers Total number of Octets of data (including bad packets) received
on the network
etherStatsUndersizePkts Number of packets received with a length less than 64 octets
etherStatsFragments Total number of packets that are not an integral number of octets
or have a bad FCS, and that are less than 64 octets long
etherStatsPkts64Octets Total number of packets received (including error packets) that
were 64 octets in length
etherStatsPkts65to127Octets Total number of packets received (including error packets) that
were 65 – 172 octets in length
etherStatsPkts128to255Octets Total number of packets received (including error packets) that
were 128 – 255 octets in length
etherStatsPkts256to511Octets Total number of packets received (including error packets) that
were 256 – 511 octets in length
etherStatsPkts512to1023Octets Total number of packets received (including error packets) that
were 512 – 1023 octets in length
etherStatsPkts1024to1518Octets Total number of packets received (including error packets) that
were 1024 – 1518 octets in length
etherStatsJabbers Total number of packets longer than 1518 octets that were not an
integral number of octets or had a bad FCS
