Need Explanation on WRED
You don’t really have an average queue length. You have a 3 areas that traffic can fall into:
1. under the min-threshold - traffic is safe 2. between the min threshold and max-threshold - traffic may be dropped according to mark-prob-denom 3. over the max-threshold - traffic will be dropped

Hi,
in configuring WRED using Random-detect interface command based on IP precedence where the Precedence, Min-threshold, Max-threshold and Mark-prob–denominator parameters are deployed.
1. what does my average queue length represent:
2. why should packet be drop when my average queue lenght equals the Min-threshold and not just when it equal the Max threshold for that precedence.
I need explanation on this.
