FCS Errors (dot3StatsFCSErrors)
The number of frames received that are an integral number of octets in length but do not pass the FCS check.
Single Collision Frames (dot3StatsSingleCollision Frames)
The number of successfully transmitted frames in which there was exactly one collision.
Multiple Collision Frames (dot3StatsMultipleCollisionFrames)
The number of successfully transmitted frames in which there was more than one collision.
SQE Test Errors (dot3StatsSQETestErrors)
The number of times that the SQE TEST ERROR message is generated by the PLS sublayer.
Deferred Transmissions (dot3StatsDeferredTransmissions)
The number of times in which the first transmission attempt is delayed because the medium is busy. This num-
ber does not include frames involved in collisions.
Late Collisions (dot3StatsLateCollisions)
The number of times that a collision is detected later than 512 bit-times into the transmission of a packet. Five
hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 Mbps system.
Excessive Collisions (dot3StatsExcessiveCollisions)
The number of frames in which transmission failed due to excessive collisions.
Other Errors (dot3StatsInternalMacTransmitErrors)
The number of frames transmission on a fails due to an internal MAC sublayer transmit error.
Carrier Sense Errors (dot3StatsCarrierSenseErrors)
The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a
frame on a particular interface.
