Statistics

Description

 

dot3StatsAlignmentErrors

A count 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.

 

The count represented by an instance of this object is

 

incremented when the alignmentError status is returned by the

 

MAC service to the Logical Link Control (LLC) (or other MAC

 

user).

 

Received frames for which multiple error conditions obtained

 

are, according to the conventions of IEEE 802.3 Layer

 

Management, counted exclusively according to the error status

 

presented to the LLC.

 

dot3StatsFCSErrors

A count 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.

 

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 obtained

 

are, according to the conventions of IEEE 802.3 Layer

 

Management, counted exclusively according to the error status

 

presented to the LLC.

 

dot3StatsSingleCollisionFrames

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 the ifOutUcastPkts,

 

ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted

 

by the corresponding instance of the

 

dot3StatsMultipleCollisionFrame object.

 

dot3StatsMultipleCollisionFrames

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

 

dot3StatsSingleCollisionFrames object.

 

dot3StatsLateCollisions

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 Mbit/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.

 

dot3StatsExcessiveCollisions

A count of frames for which transmission on a particular

 

interface fails due to excessive collisions.
