Name RFC Description
rfc2665_Dot3Stats
ExcessiveCollisions 2665 The number of frames for which transmission on a particular interface
fails due to excessive collisions. This counter does not increment when
the interface is operating in full-duplex mode. Discontinuities in the
value of this counter can occur at reinitialization of the management
system and at other times as indicated by the value of
ifCounterDiscontinuityTime.
rfc2665_Dot3StatsFCS
Errors
2665 The number of frames received on a particular interface that are an
integral number of octets in length but do not pass the FCS check. This
count does not include frames received with a frame-too-long or
frame-too-short error. 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 with
multiple error conditions are counted exclusively according to the error
status presented to the LLC, per the conventions of IEEE 802.3 Layer
Management. Coding errors detected by the physical layer for speeds
above 10 Mb/s cause the frame to fail the FCS check. Discontinuities in
the value of this counter can occur at reinitialization of the management
system and at other times as indicated by the value of
ifCounterDiscontinuityTime.
rfc2665_Dot3StatsFrame
TooLongs
2665 The number 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 with
multiple error conditions are counted exclusively according to the error
status presented to the LLC, per the conventions of IEEE 802.3 Layer
Management. Discontinuities in the value of this counter can occur at
reinitialization of the management system and at other times as
indicated by the value of ifCounterDiscontinuityTime.
rfc2665_Dot3StatsInternal
MacReceiveErrors 2665 The number of frames for which reception on a particular interface 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 dot3StatsFrameTooLongs object, the
dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors object.
The precise meaning of the count represented by an instance of this
object is implementation-specific. An instance of this object can
represent a count of receive errors on a particular interface that are not
otherwise counted. Discontinuities in the value of this counter can occur
at reinitialization of the management system and at other times as
indicated by the value of ifCounterDiscontinuityTime.
rfc2665_Dot3StatsInternal
MacTransmitErrors
2665 The number 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. An instance of this object can
represent a count of transmission errors on a particular interface that
are not otherwise counted. Discontinuities in the value of this counter
can occur at reinitialization of the management system and at other
times as indicated by the value of ifCounterDiscontinuityTime.
