Description
A count of frames, for which reception on a particular MLT fails due
to an internal MAC sublayer receive error. A frame is only counted
by an instance of this object if it is not counted by the corresponding
instance of either the FrameTooLongs object, the AlignmentErrors
object, or the FCSErrors object.
The precise meaning of the count represented by an instance of
this object is implementation specific. In particular, an instance of
this object can represent a count of receive errors on a particular
interface that are not otherwise counted.
The number of times that the carrier sense condition was lost
or never asserted when attempting to transmit a frame on a
particular MLT. The count represented by an instance of this object
is incremented at most once per transmission attempt, even if the
carrier sense condition fluctuates during a transmission attempt.
A count of frames received on a particular MLT that exceed the
maximum permitted frame size. The count represented by an
instance of this object is incremented when the frameTooLong
status is returned by the MAC service to the LLC (or other MAC
user). Received frames with multiple error conditions are, according
to the conventions of IEEE 802.3 Layer Management, counted
exclusively according to the error status presented to the LLC.
A count of times that the SQE TEST ERROR message is generated
by the PLS sublayer for a particular MLT. The SQE TEST ERROR
message 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.
A count of frames, for which the first transmission attempt on a
particular MLT is delayed because the medium is busy. The count
represented by an instance of this object does not include frames
involved in collisions.
A count of successfully transmitted frames on a particular MLT,
for which transmission is inhibited by exactly one collision. A
frame counted by an instance of this object is also counted
by the corresponding instance of either the OutUcastPkts
object, the OutMulticastPkts object, or the OutBroadcastPkts
object, and is not counted by the corresponding instance of the
MultipleCollisionFrames object.
A count of successfully transmitted frames on a particular MLT,
for which transmission is inhibited by more than one collision. A
frame counted by an instance of this object is also counted by
the corresponding instance of either the OutUcastPkts object, the
OutMulticastPkts object, or the OutBroadcastPkts object, and is not
counted by the corresponding instance of the SingleCollisionFrames
object.
