What is fcmPortClass3Discards?
This Counter64 counts Class 3 frames that were discarded upon reception at this port, meaning storage traffic was silently dropped since Class 3 offers no retransmission. Any nonzero value here is significant to an admin because it directly represents lost SCSI I/O that the upper-layer protocol must detect and retry.
