This read-create INTEGER, as a percentage from 0 to 100, sets the WRED minimum threshold for Drop Precedence 1 traffic; like its DP0 sibling, the source MIB's description text is copy-pasted and mislabels this as Drop Precedence 2, but the object's name identifies it as the DP1 minimum threshold. An admin typically sets this minimum threshold lower than the DP0 minimum, so DP1 traffic begins experiencing random early drops at a shallower queue-fill level than the more-protected DP0 class. For example, setting this minimum threshold to 50 percent, below a 70 percent DP0 minimum, means DP1 packets start facing random drops once the queue is half full, well before DP0 traffic is affected.
