Ethernet MIB

# Ethernet Errors

AlignmentErrors. A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.

FCSErrors. A count of frames received on a particular interface that are not an integral number of octets in length and do not pass the FCS check.

InternalMacTransmitErrors. A count of frames for which transmission on a particular interface 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 dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions object, or the dot3StatsCarrierSenseErrors object.

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 transmission errors on a particular interface that are not otherwise counted.

InternalMacReceiveErrors. A count of frames for which reception on a particular interface 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 dot3StatsFrameTooLongs object, the dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors object.

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.

CarrierSenseErrors. The number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular interface.

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.

SingleCollisionFrames. A count of successfully transmitted frames on a particular interface for which transmission is inhibited by exactly one collision.

MultipleCollisionFrames. A count of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision.

SQETestError. A count of times that the SQE TEST ERROR message is generated by the PLS sublayer for a particular interface.

DeferredTransmissions. A count of frames for which the first transmission attempt on a particular interface is delayed because the medium is busy.

LateCollisions. The number of times that a collision is detected on a particular interface later than 512 bit-times into the transmission of a packet.

ExcessiveCollisions. A count of frames for which transmission on a particular interface fails due to excessive collisions.

FrameTooLongs. A count of frames received on a particular interface 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 for which multiple error conditions obtain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.

FrameTooShorts. The total number of frames that are too short that were encountered on this interface."

LinkFailures. The total number of link failures encountered on this interface.

PacketErrors. The total number of packet errors encountered on this interface.

CarrierErrors. The total number of carrier errors encountered on this interface.

LinkInactiveErrors. The total number of link inactive errors encountered on this interface.

InFlowCtrlPkts. The total number of flow control packets received by this interface.

OutFlowCtrlPkts. The total number of flow control packets transmitted by this interface.
