This read-create INTEGER sets the maximum drop probability applied to Drop Precedence 2 traffic once the queue reaches the DP2 WRED maximum threshold. An admin typically configures this as the highest drop probability among the three DP classes, ensuring the least-protected traffic bears the brunt of congestion-driven discards. For example, setting this probability to 60 percent for DP2, compared to lower values for DP0 and DP1, means excess or best-effort traffic is discarded much more aggressively than higher-priority classes once congestion sets in.
