This 64-bit counter tallies the same SRP framing anomaly — an empty packet with a valid Start-Of-Packet signal producing an incorrect CRC — but observed on frames coming from this router's own higher-layer stack rather than off the ring, over the current, still-running 15-minute window. Seeing this specific anomaly generated locally rather than arriving from the ring points at this box's own SRP interface hardware or driver as the source, which is a materially different repair path than chasing it on the ring fiber. If this counter increments while the ring-side srpRingCurRxErrorsSideBadPackets stays at zero, that isolates the anomaly to this router's own interface card rather than to the ring media.
