single-collision-frames 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 out-ucast-pkts, out-multicast-pkts, or
out-broadcast-pkts, and is not counted by the corresponding instance of
the multiple-collision-frames object. This counter does not increment
when the interface is operating in full-duplex mode.
multiple-collision-frames 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 out-ucast-pkts, out-multicast-pkts, or
out-broadcast-pkts, and is not counted by the corresponding instance of
the single-collision-frames object. This counter does not increment
when the interface is operating in full-duplex mode.
sqe-test-errors A count of times that the SQE TEST ERROR message is generated by
the PLS sublayer for a particular interface. The SQE TEST ERROR is
set in accordance with the rules for verification of the SQE detection
mechanism in the PLS Carrier Sense Function, as described in IEEE
Std. 802.3, 1998 Edition, section 7.2.4.6. This counter does not
increment on interfaces operating at speeds greater than 10 Mbps or on
interfaces operating in full-duplex mode.
deferred-transmissions 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. This counter does not increment when the
interface is operating in full-duplex mode.
late-collisions The number of times that a collision is detected on a particular interface
later than one Ethernet slot-time unit into the transmission of a packet.
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. This counter does not increment when the
interface is operating in full-duplex mode.
excessive-collisions A count 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.
internal-mac-transmit-errors 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 the late-collisions object, the excessive-collisions object, or
the carrier-sense-errors 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 is not otherwise
counted.
