Field

Description

 

 

 

 

 

 

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.

 

 

 

 

 

 

SQETestError

A count 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 and its generation is described in section

 

 

 

7.2.4.6 of the same document.

 

 

 

 

 

 

DeferredTransmiss

A count of frames 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

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, ifOutMulticastPkts, or ifOutBroadcastPkts, and

 

 

 

is not counted by the corresponding instance of the

 

 

 

MultipleCollisionFrames object.

 

 

 

 

 

 

MultipleCollFrames

A count 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 object.

 

 

 

 

 

 

LateCollisions

The number of times that a collision is detected on a particular

 

 

 

MLT later than 512 bit-times into the transmission of a packet.

 

 

 

Five hundred and twelve bit-times corresponds to 51.2

 

 

 

microseconds on a 10 Mb/s system. 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.

 

 

 

 

 

 

ExcessiveColls

A count of frames for which transmission on a particular MLT

 

 

 

fails due to excessive collisions.
