AlignmentErrors
|
Indicates the number of frames received on a particular MLT that are not an integral number of octets in length and do not pass the FCS check.
The count represented by an instance of this object is incremented when the alignmentError 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.
|
FCSErrors
|
Indicates the number of frames received on an MLT that are an integral number of octets in length but do not pass the FCS check.
The count represented by an instance of this object is incremented when the frameCheckError 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.
|
IMacTransmitError
|
Indicates the number of frames 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 CarrierSenseError object.
|
IMacReceiveError
|
Indicates the number 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, of the FCSErrors objects.
Note: The precise meaning of the count represented by an instance of this object is implementation specific. In particular, an instance of this object may represent a count of receive errors on a particular interface that are not otherwise counted.
|
CarrierSenseError
|
Indicates 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.
|
FrameTooLong
|
Indicates the number of frames received on a particular MLT that exceed the maximum permitted size (1518 octets).
The count represented by an instance of this object is incremented when the frame TooLong 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
|
Signal Quality Error (SQE)--Indicates the number of times that the SQE TEST ERROR message is generated by the PLS sublayer for a particular MLT.
|
DeferredTransmiss
|
A count of frames for which the first transmission attempt on a particular MLT is delayed because the medium is busy.
Note: The count represented by an instance of this object does not include frames involved in collisions.
|
SingleCollFrames
|
Indicates the number 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 objects is also counted by the corresponding instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and it not counted by the corresponding instance of the MultipleCollisionFrames object.
|
MultipleCollFrames
|
Indicates the number of successfully transmitted frames 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 instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by the corresponding instance of the SingleCollisionFrames objects.
|
LateCollisions
|
Indicates the number of times that a collision is detected on a particular MLT later than 512 bit-times (64 octets) into the transmission of a packet.
On a 10 Mb/s system, 512 bit-times corresponds to 51.2 microseconds. A (late) collision included in a count represented by an instance of this object is also considered as a (generic) collision for purposes of other collision-related statistics.
|
ExcessiveCollisions
|
Indicates the number of frames for which transmission on a particular MLT fails due to excessive collisions.
