This read-create INTEGER, as a percentage from 0 to 100, sets the WRED maximum threshold for Drop Precedence 0 traffic, the queue-fill level at which the random-early-drop probability reaches its configured peak, per rlQosRedProbDp0, for this class. An admin pairs this with the DP0 minimum threshold to define the full WRED ramp for the most protected traffic, controlling how sharply drop probability increases as the queue fills between the two thresholds. For example, setting this maximum threshold to 95 percent means DP0 packets face steadily increasing drop probability between the minimum threshold and 95 percent queue fill, reaching the configured peak probability only at that upper bound.
