This read-only counter tracks the number of complete frames the agent recognized from the RAID7 array, including frames later discarded due to the various error conditions counted by the other Link objects. Admins use it as the baseline against which framing, checksum, and version error counters are compared to compute a frame error rate. If received frames total 1000 and framing errors total 950, the admin can tell the vast majority of frames from the array are malformed.
