QoS configuration examples

Configure the WRED algorithm on an individual queue when queue-limit is defined in time

For a QoS policy you can configure weighted random early detection (WRED). WRED enables early detection of congestion.

  1. Configure the exponentially weighted moving average (EWMA) filter weight. 
    user@system# set policy qos name policy-1 shaper profile-1 queue 0 wred-map-time filter-weight 1
  2. Configure the maximum value for the inverse of packet marking probability. 
    user@system# set policy qos name policy-1 shaper traffic-class 1 random-detect mark-probability 2
  3. Configure the maximum threshold for the queue. 
    user@system# set policy qos name policy-1 shaper traffic-class 1 random-detect max-threshold 100
  4. Configure the minimum threshold for the queue.
    user@system# set policy qos name policy-1 shaper traffic-class 1 random-detect min-threshold 5
  5. Commit the configuration.
    user@system# commit
You have configured WRED queues for all traffic class 1 queues of policy-1.
