Description: The total number of octets contained in the valid frames that have been received on the ports in this group. If an implementation can not obtain a count of octets as seen by the repeater itself, this counter may be the summation of the values of the rptrMonitorPortReadableOctets counters for all of the ports in the group.

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 divided by the number of ports in the repeater.

For 100Mb/s repeaters processing traffic at a maximum rate, this counter can roll over in less than 6 minutes divided by the number of ports in the repeater. 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 rptrMonUpper32TotalOctets object, or to use the 64-bit counter defined by rptrMonHCTotalOctets instead of the two 32-bit counters.
