Description
The number of frames for which
transmission on a particular interface fails
because of an internal MAC sublayer
transmit error. A frame only is 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 number of frames for which reception
on a particular interface fails because
of an internal MAC sublayer transmit
error. A frame only is 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 number of times that the carrier sense
conditions was lost or never asserted
when attempting to transmit a frame on a
particular interface.
The number of times that the SQE TEST
ERROR message is generated by the PLS
sublayer for a particular interface. The
SQE TEST ERROR 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.
The number of frames for which the
first transmission attempt on a particular
interface is delayed because the medium
is busy.
The number of successfully transmitted
frames on a particular interface for which
transmission is inhibited by more than one
collision.
The number of successfully transmitted
frames on a particular interface for which
transmission is inhibited by a single
collision.
