Selecting the QoS queuing method

Follow these steps to change the queuing method.

By default, Ruckus devices use the weighted round robin (WRR) method of packet prioritization.

  1. Enter global configuration mode.
    
    device# configure terminal
    
  2. Select the QoS queuing method.
    • Change the queuing method to strict priority (SP).

      
      device(config)# qos mechanism strict
      bandwidth scheduling mechanism: strict priority
      Qos profile bandwidth percentages are ignored
      
    • Change the queuing method to mixed SP and WRR.

      
      device(config)# qos mechanism mixed-sp-wrr
      bandwidth scheduling mechanism: mixed weighted priority with strict priority

      Profile qosp1     : Priority1          bandwidth requested  15% calculated  15%
      Profile qosp0     : Priority0(Lowest)  bandwidth requested  15% calculated  15%

      Profile qosp1                           : Priority1                 bandwidth requested  15% calculated  15%
      Profile qosp0                           : Priority0(Lowest)         bandwidth requested  15% calculated  15%
      
    Observe that the verification step is not necessary with either of these choices.
  3. Return to privileged EXEC mode.
    
    device(config)# exit
    
  4. Verify the configuration
    
    device# show qos scheduler-profile all
    User Scheduler Profile: test	Scheduling Option: Mixed-SP-WRR
