Performance Management on Virtual Services Platform 4000 Series Version 5.1.2

Name Description
conditions occur are, according to the conventions of IEEE 802.3 Layer
Management, counted exclusively according to the error status presented
to the LLC.
IMacTransmitError Specifies the frame count for which transmission on a particular MLT fails
due to an internal MAC sublayer transmit error. A frame is only counted by
an instance of this object if it is not counted by the corresponding instance
of either the LateCollisions object, the ExcessiveCollisions object, or the
CarrierSenseErrors object.
IMacReceiveError Specifies the frame count 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 receive errors on a particular interface that are not otherwise
counted.
CarrierSenseError Specifies 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 increments at most
once for each transmission attempt, even if the carrier sense condition
fluctuates during a transmission attempt.
FrameTooLong Specifies the frame count received on a particular MLT that exceeds the
maximum permitted frame size. The count represented by an instance of
this object increments when the frameTooLong status is returned by the
MAC service to the LLC (or other MAC user). Received frames for which
multiple error conditions occur are, according to the conventions of IEEE
802.3 Layer Management, counted exclusively according to the error
status presented to the LLC.
SQETestError Specifies the number 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.
DeferredTransmiss Specifies the frame count 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.
SingleCollFrames Specifies a count of successfully transmitted frames on a particular MLT for
which transmission is inhibited by exactly one collision. A frame that is
counted by an instance of this object is also counted by the corresponding
instance of either the ifOutUcastPkts object, the ifOutMulticastPkts object,
or the ifOutBroadcastPkts object, and is not counted by the corresponding
instance of the MultipleCollisionFrames object.
MultipleCollFrames Specifies the successfully transmitted frame count on a particular MLT for
which transmission is inhibited by more than one collision. A frame that is
counted by an instance of this object is also counted by the corresponding
