This counter is incremented by OctetCount for each frame received on this port which has been determined to be a readable frame (i.e., including FCS octets but excluding framing bits and dribble bits). A discontinuity may occur in the value when the value of object rptrMonitorPortLastChange changes. This statistic provides an indicator of the total data transferred. The approximate minimum time for rollover of this counter in a 10Mb/s repeater is 58 minutes. For ports receiving traffic at a maximum rate in a 100Mb/s repeater, this counter can roll over in less than 6 minutes. Since that amount of time could be less than a management station's poll cycle time, in order to avoid a loss of information a management station is advised to also poll the rptrMonitorPortUpper32Octets object, or to use the 64-bit counter defined by rptrMonitorPortHCReadableOctets instead of the two 32-bit counters."

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 shortde Graaf, et.⌨️ 快捷键说明
