Media Counters
Alignment Errors Frames received that are not an integral number of octets in length
FCS Errors Frames received that do not pass the FCS check
Single Collisions Successfully transmitted frames which experienced exactly one collision
Multiple Collisions Successfully transmitted frames which experienced more than one collision
SQE Test Errors Number of times SQE test error message is generated
Deferred Transmissions Frames for which first transmission attempt is delayed because the medium is busy
Late Collisions Number of times a collision is detected later than 512 bit-times into the transmission of
a packet
Excessive Collisions Frames for which transmission fails due to excessive collisions
