Statistic | Description |
---|---|
dot3StatsAlignmentErrors | The number of frames received on a particular interface that are not an integral number of octets in length and do not pass the Frame Check Sequence (FCS) check. This number is incremented when the alignmentError status is returned by the MAC service to the Logical Link Control (LLC) (or another MAC user). Received frames for which multiple error conditions are generated are counted exclusively according to the error status presented to the LLC (as per IEEE 802.3 Layer Management). |
dot3StatsFCSErrors | The number of frames received on a particular interface that are an integral number of octets in length but do not pass the Frame Check Sequence (FCS) check. This number does not include frames received with frame-too-long or frame-too-short errors. This number is incremented when the frameCheckError status is returned by the MAC service to the LLC (or another MAC user). Received frames for which multiple error conditions are obtained are counted exclusively according to the error status presented to the LLC (as per IEEE 802.3 Layer Management). Note: Coding errors detected by the physical layer for speeds above 10 Mb/s cause the frame to fail the FCS check. |
dot3StatsSingle-CollisionFrames | The number of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision. The counted frame is also counted by the corresponding instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts objects, and is not counted by an instance of the dot3StatsMultipleCollision-Frame object. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsMultiple-CollisionFrames | The number of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision. The counted frame is also counted by the corresponding instance of either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts objects, and is not counted by the corresponding instance of the dot3StatsSingleCollision-Frames object. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsSQETest-Errors | The number of times that the SQE TEST ERROR message is generated by the PLS sub layer for a particular interface. The SQE TEST ERROR is set in accordance with the rules for the verification of the SQE detection mechanism in the PLS Carrier Sense Function, as described in IEEE Std.802.3-1998 Edition, section 7.2.4.6. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsDeferred-Transmissions | The number of frames for which the first transmission attempt on a particular interface is delayed because the medium is busy. This number does not include frames involved in collisions. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsLate-Collisions | The number of times that a collision is detected on a particular interface later than one slot time into the transmission of a packet. Five hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 Mbit/s system. A late collision included in this count is also considered as a generic collision for purposes of other collision-related statistics. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsExcessiveCollisions | The number of frames for which transmission on a particular interface fails due to excessive collisions. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsInternal-MacTransmitErrors | The number of frames for which transmission on a particular interface fails due to an internal MAC sub layer transmit error. A frame is only counted if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions object, or the dot3Stats-CarrierSenseErrors object. The precise meaning of this count is implementation-specific. In particular, an instance of this object may represent a count of transmission errors on a particular interface that are not otherwise counted. |
dot3StatsCarrier-SenseErrors | The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular interface. This number is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt. Note: This counter does not increment when the interface is operating in full-duplex mode. |
dot3StatsFrameToo-Longs | The number of frames received on a particular interface that exceed the maximum permitted frame size. This number is incremented when the frameTooLong status is returned by the MAC service to the LLC (or another MAC user). Received frames for which multiple error conditions are obtained are counted exclusively according to the error status presented to the LLC, as per IEEE 802.3 Layer Management. |
dot3StatsInternal-MacReceiveErrors | The number of frames for which reception on a particular interface fails due to an internal MAC sub-layer receive error. A frame is only counted if it is not counted by the corresponding instance of either the dot3StatsFrameTooLongs object, the dot3Stats-AlignmentErrors object, or the dot3StatsFCSErrors object. The precise meaning of the count is implementation-specific. In particular, an instance of this object may represent a count of received errors on a particular interface that are not otherwise counted. |
dot3Coll-Frequencies | The number of individual MAC frames for which the transmission (successful or otherwise) on a particular interface occurs after the frame has experienced exactly the number of collisions specified by the index. For example, a frame which is transmitted after experiencing exactly four collisions would be indicated by incrementing only dot3CollFrequencies [4]. No other instance of dot3CollFrequencies would be incremented in this example. Note: This counter does not increment when the interface is operating in full-duplex mode. |
