               following two conditions.  Only one test need be
               made.  a) The ActivityDuration is greater than
               ShortEventMaxTime and less than ValidPacketMinTime
               and the CollisionEvent signal is deasserted.  b)
               The OctetCount is less than 64, the
               ActivityDuration is greater than ShortEventMaxTime
               and the CollisionEvent signal is deasserted.
               ValidPacketMinTime is greater than or equal to 552
               bit times and less than 565 bit times.

               An event whose length is greater than 74 bit times
               but less than 82 bit times shall increment either
               the shortEvents counter or the runts counter but
               not both.  A CarrierEvent greater than or equal to
               552 bit times but less than 565 bit times may or
               may not be counted as a runt.

               ValidPacketMinTime has tolerances included to
               provide for circuit losses between a conformance
               test point at the AUI and the measurement point
               within the state machine.

               Runts usually indicate collision fragments, a
               normal network event.  In certain situations
               associated with large diameter networks a
               percentage of collision fragments may exceed
               ValidPacketMinTime.

               A discontinuity may occur in the value
               when the value of object
               rptrMonitorPortLastChange changes.

               The approximate minimum time for rollover of this
               counter is 16 hours in a 10Mb/s repeater."

               frame received by this port that meets all
               of the conditions required by only one of the
               following two measurement methods:

               Measurement method A:  1) The CollisionEvent
               signal is not asserted (10Mb/s operation) or
               the Collision Count Increment state of the
               partition state diagram (fig 27-8 of
               [IEEE 802.3 Std]) has not been entered
               (100Mb/s operation).  2) The ActivityDuration
               is greater than ValidPacketMinTime.  3) The
               frequency (data rate) is detectably mismatched
               from the local transmit frequency.

               Measurement method B:  1) The CollisionEvent
               signal is not asserted (10Mb/s operation)
               or the Collision Count Increment state of the
               partition state diagram (fig 27-8 of
               [IEEE 802.3 Std]) has not been entered
               (100Mb/s operation).  2) The OctetCount is
               greater than 63.  3) The frequency (data
               rate) is detectably mismatched from the local
               transmit frequency.  The exact degree of
               mismatch is vendor specific and is to be
               defined by the vendor for conformance testing.

               When this event occurs, other counters whose
               increment conditions were satisfied may or may not
               also be incremented, at the implementor's
               discretion.  Whether or not the repeater was able
               to maintain data integrity is beyond the scope of
               this standard.

               This counter is redundant in the sense that it is
               the summation of information already available
               through other objects.  However, it is included

               object as a means of tracking the health of a port
