This read-create INTEGER, as a percentage from 0 to 100, sets the WRED maximum threshold for Drop Precedence 1 traffic, the queue-fill point at which its drop probability reaches the peak configured in rlQosRedProbDp1. An admin uses this together with the DP1 minimum threshold to define how quickly the drop probability ramps for this middle-priority class as congestion builds. For example, setting this maximum threshold to 85 percent for DP1, compared to 95 percent for DP0, means DP1 traffic reaches its peak drop probability at a lower queue-fill level than the more protected DP0 class.
