SNMPv2-SMICounter32
This counter is incremented by one for each
CarrierEvent on this port with ActivityDuration
less than ShortEventMaxTime. ShortEventMaxTime is
greater than 74 bit times and less than 82 bit
times. ShortEventMaxTime has tolerances included
to provide for circuit losses between a
conformance test point at the AUI and the
measurement point within the state machine.
Notes:
ShortEvents may indicate externally
generated noise hits which will cause the repeater
to transmit Runts to its other ports, or propagate
a collision (which may be late) back to the
transmitting DTE and damaged frames to the rest of
the network.
Implementors may wish to consider selecting the
ShortEventMaxTime towards the lower end of the
allowed tolerance range to accommodate bit losses
suffered through physical channel devices not
budgeted for within this standard.
The significance of this attribute is different
in 10 and 100 Mb/s collision domains. Clause 9
repeaters perform fragment extension of short
events which would be counted as runts on the
interconnect ports of other repeaters. Clause
27 repeaters do not perform fragment extension.
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.
