Error: "traffic-class <X> max-threshold <Y> must be less than the queue limit <Z>"

Cause

You tried to configure a WRED configuration on a traffic class basis, and you have defined the WRED max-threshold value to be the same or greater that the queue-limit value of the traffic class.

You will trigger this error if you combine commands like these:

set policy qos name <policy-name> shaper traffic-class <X> random-detect max-threshold <Y>
set policy qos name <policy-name> shaper traffic-class <X> queue-limit <Z>

Remedy

Apply one of these solutions:
  • Decrease the max-threshold value to be less than the queue-limit value.
  • Increase the queue-limit value to be more than the max-threshold value.
