2-125
FCS Errors 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. 
Excessive Collisions 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.
Single Collision Frames The number of successfully transmitted frames 
for which transmission is inhibited by exactly 
one collision.
Internal MAC Transmit 
Errors
A count of frames for which transmission on a 
particular interface fails due to an internal MAC 
sublayer transmit error. 
Multiple Collision 
Frames
A count of successfully transmitted frames for 
which transmission is inhibited by more than 
one collision.
Carrier Sense Errors The number of times that the carrier sense 
condition was lost or never asserted when 
attempting to transmit a frame. 
 SQE Test Errors  A count of times that the SQE TEST ERROR 
message is generated by the PLS sublayer for a 
particular interface. 
Frames Too Long A count of frames received on a particular 
interface that exceed the maximum permitted 
frame size.
Deferred Transmissions A count of frames for which the first transmission 
attempt on a particular interface is delayed 
because the medium was busy.
Internal MAC Receive 
Errors
A count of frames for which reception on a 
particular interface fails due to an internal MAC 
sublayer receive error.
