# Modify drop parameters for queue 1 in the WRED table queue-table1: set the lower threshold to 10
and the degree of the included angle between the drop probability and queue length percentage to 30
for packets with drop level 1 in queue 1 (assuming the WRED table queue-table1 is applied to a port on
an EA LPU).
