This 64-bit counter, active only when rate limiting is enabled on this Virtual Interface, totals the number of receive bytes submitted to the rate-limiting mechanism, per the source description covering the receive-side counterpart to the transmit-side submitted counters. An admin uses it as the baseline inbound demand figure to compare against the corresponding dropped-bytes counter. For example, tracking csOrionViStatsRateLimitRxBytesSubmitted over time on this VI shows how much inbound traffic is being evaluated by the rate limiter, regardless of whether it is ultimately dropped.
