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 occur are, according to the

conventions of IEEE 802.3 Layer Management, counted

exclusively according to the error status presented to the

LLC.

SQETestErrors A count of times that the SQE TEST ERROR message is

generated by the PLS sublayer for a particular interface.

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.

DeferredTransmissions A count of frames for which the first transmission attempt on

a particular interface is delayed because the medium is busy.

The count represented by an instance of this object does not

include frames involved in collisions.

SingleCollisionFrames A count of successfully transmitted frames on a particular

interface 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.

MultipleCollisionFrames A count of successfully transmitted frames on a particular

interface 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 interface 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.

ExcessiveCollisions A count of frames for which transmission on a particular

interface fails due to excessive collisions.

Poll Interval Statistics are updated based on the poll interval.
