Enter the weight as a number to be used to calculate the average-queue size. The range is 1 to 15. The default is 0.

Usage Information

If the average queue size is more than the maximum threshold of WRED, the packet is dropped. If the average queue size is between the minimum and maximum threshold values, the decision to drop or queue the packet is taken based on the packet drop probability. The probability that a packet is dropped depends on the minimum threshold, maximum threshold, and mark probability denominator.
