This counts frames properly received from the Ethernet link, incremented only once reception completes and all data bytes are stored in memory. As the receive-side counterpart to cdmipEtherTransmitGoodFrames, its growth rate is the baseline an admin compares against the various receive error counters to judge whether the interface's error rate is proportionally small or alarmingly high relative to actual traffic volume. A steady climb here alongside near-zero values in cdmipEtherReceiveCRCErrorFrameCount and cdmipEtherReceiveFifoOverrunErrorCount indicates a healthy, low-error receive path.
