Object Description
The queue number (QoS class) for which the configuration below applies.  Queue
Controls whether RED is enabled for this queue.  Enable
Controls the lower RED threshold. If the average queue filling level is below this
threshold, the drop probability is zero.
This value is restricted to 0-100.
 Min. Threshold
Controls the drop probability for frames marked with Drop Precedence Level 1
when the average queue filling level is 100%.
This value is restricted to 0-100.
 Max. DP 1
Controls the drop probability for frames marked with Drop Precedence Level 2
when the average queue filling level is 100%.
This value is restricted to 0-100.
 Max. DP2
Controls the drop probability for frames marked with Drop Precedence Level 3
when the average queue filling level is 100%.
This value is restricted to 0-100.
 Max. DP3
