SQE Test Errors The number of times that the SQE TEST ERROR message is generated by the PLS sublayer
for a particular interface. The SQE TEST ERROR is defined in section 7.2.2.2.4 of ANSI/
IEEE 802.3-1985, and its generation is described in section 7.2.4.6 of the same document.
Deferred Transmissions The number of frames for which the first transmission attempt on a particular interface is
delayed because the medium is busy.
Single Collision Frames The number of successfully transmitted frames on a particular interface for which
transmission is inhibited by more than one collision.
Multiple Collision Frames The number of successfully transmitted frames on a particular interface for which
transmission is inhibited by a single collision.
Late Collisions The number of times a collision is detected on a particular interface later than 512 bit-times
into the transmission of a packet.
Excessive Collisions The number of frames for which transmission on a particular interface fails due to excessive
collisions.
