What is h3cIfQoSWredPreTailDropNum?
This Counter64 counts packets discarded when queue buffers are completely full, a last-resort drop after WRED thresholds. It signals that congestion exceeded the system's ability to manage traffic gracefully. A high tail-drop rate indicates insufficient link capacity or poorly tuned QoS settings.
