Statistics

Description

 

 

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.

 

 

dot3StatsInternalMacTransmitErrors

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.

 

 

dot3StatsFrameTooLongs

A count of frames received on a particular interface that exceeds

 

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 obtained are,

 

according to the conventions of IEEE 802.3 Layer Management,

 

counted exclusively according to the error status presented to the

 

LLC.
