Release Information
Statement introduced in Junos OS Release 11.1 for the QFX Series.
Description
When configuring WRED, map the packet drop-probability to the fullness of a queue (fill-level). You configure the fill-level and drop-probability statements in related pairs by specifying a low fill-level value at which packets begin to drop (the drop probability is zero until the queue reaches this level of fullness) and a high fill-level value at which packets drop at the highest drop probability. As the queue fills from the low fill level to the high fill level, the rate of packet drop increases in a linear pattern from zero to the high drop probability.
Options
0—Probability that packets will drop at the lowest fill-level value. This is always zero, because until the queue reaches the specified low fill-level value, no packets are scheduled to drop.
high-value—The maximum probability that packets will drop before queue fullness exceeds the high value of the queue fill-level, expressed as a percentage. If the queue fills beyond the high fill-level value, all packets drop.
Range: 0 through 100
