 This shows drops, ECN marks, and per-tin flow counts. If you see high drop rates, your bandwidth setting may be too close to the actual line speed. Lower it by another 5%. This shows drops, ECN marks, and per-tin flow counts. If you see high drop rates, your bandwidth setting may be too close to the actual line speed. Lower it by another 5%.
