This OID stores the far-end packet loss ratio in millionths of a percent (0–100,000,000), measuring data loss on the return path from a remote endpoint. Network engineers consult this value to determine whether packet loss occurs on the outbound direction, helping pinpoint whether problems originate locally or at the remote site. A reading of 500000 means 0.5% loss from the far-end, which when combined with near-end loss helps diagnose asymmetric path quality.
