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.
Example
DellEMC(conf-qos-policy-out) # wred weight 5
wred-profile
Create a WRED profile and name the profile.
S6000–ON
Syntax
