Statistic Description
Single Collisions 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
dot3StatsMultipleCollision-Frame object.
Multi Collisions 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 the
ifOutUcastPkts, ifOutMulticastPkts, or
ifOutBroadcastPkts, and is not counted by the corresponding instance of the
dot3StatsSingleCollision-Frames object.
Late Collisions 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.
Excess Collisions A count of frames for which transmission on a particular interface fails due to excessive
collisions.
Internal MACErrors A count of frames for which transmission on a particular interface fails due to an internal
MAC sub layer transmit error. A frame is only counted by an instance of this object if it
is not counted by the corresponding instance of the
dot3StatsLateCollisions
object, the
dot3StatsExcessiveCollisions object, or the dot3Stats-
CarrierSenseErrors
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.
Frame Too Longs 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.
Mac Receive Errors A count of frames for which reception on a particular interface fails due to an internal
MAC sub layer receive error. A frame is only counted by an instance of this object if it
is not counted by the corresponding instance of the
dot3StatsFrameTooLongs
object, the
dot3Stats-AlignmentErrors object, or the
dot3StatsFCSErrors 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 received errors on a particular interface that are not
otherwise counted.
