Configuration Procedure - HP 5920 Configuration Manual

To use better effort to forward higher-priority traffic, configure a lower drop probability for a queue
•
with a greater queue number. Set different drop parameters for queue 0, queue 3, and queue 7.
Drop packets according to their colors. In queue 0, set the drop probability to 25%, 50%, and 75%
•
for green, yellow, and red packets, respectively. In queue 3, set the drop probability to 5%, 10%,
and 25% for green, yellow, and red packets, respectively. In queue 7, set the drop probability to 1%,
5%, and 10% for green, yellow, and red packets, respectively.
Enable ECN for queue 7.
