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.
