dot3StatsSingleColFrames 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 either the ifOutUcastPkts, ifOutMulticastPkts, or ifOutBroadcastPkts, and is not
counted by the corresponding instance of the dot3StatsMultipleCollisionFrames object.
dot3Stats MultiColFrames 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 th is object
is also counted by the corresponding instance of either the ifOutUcastPkts,
ifOutMulticastPkts, or ifOutBroadcastPkts, and is not coun ted by the corr es pond ing
instance of the dot3StatsSingleCollisionFrames object.
dot3StatsSQETestErrors A count of times that the SQE TEST ERROR message is generated by the PL S su blay er f or
a particular interface. The SQE TEST ERROR message is defined in section 7.2.2.2.4 of
ANSI/IEEE 802.3-1985 and its generation is described in sect ion 7. 2.4. 6 o f the same
document.
dot3StatsDeferred
Transmisions A count of frames for which the first transmission attempt on a particular interface is
delayed because the medium is busy. The count represented by an instance of this object
does not include frames involved in collisions.
dot3StatsLateCollisions7Number of times that a collision is detected on a particular interface later than 512 bit-times
into the transmission of a packet.
dot3StatsExcessiveCollisions A count of frames for which transmission on a particular interface fails due to excessive
collisions.
dot3StatsInternalMacTransmit
Errors8A 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.
dot3StatsCarrierSenseErrors Number of times that the carrier sense condition was lost or never asserted when attemp ting
to transmit a frame on a particular interface. The count represented by an instance of this
object is incremented at most once per transmission attempt, even if the carrier sense
condition fluctuates during a transmission attempt.
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 counted exclusively
according to the error status presented to the LLC.
dot3StatsInternalMacReceiveE
rrors9A count 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.
Flowcontrol counters version 1
txPause Number of control frames transmitted at the gigabit level. This counter is valid only on a
Gigabit Ethernet port.
