Table 47 Ethernet Errors tab fields

Field Description

AlignmentErrors A count 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 A count 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 A count 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 CarrierSenseErrors object.

IMacReceiveError 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 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

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 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 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.
