Creating a quality of service rule

You can create a quality of service rule in the SD-WAN instance template or in the controller configuration menu. If you create a quality of service rule in an SD-WAN instance template, that quality of service rule is not created in the controller configuration menu of already deployed SD-WAN instances.

To create a quality of service rule:

1. Create a quality of service rule:
   • If you want to create a quality of service rule in an SD-WAN instance template, go to the SD-WAN → SD-WAN instance templates section, click the SD-WAN instance template, and select the QoS rules tab.
   • If you want to create a quality of service rule in the controller settings menu, go to the Infrastructure section, click Management → Configuration menu next to the controller, and go to the QoS rules section.

   The table of quality of service rules is displayed.

2. Click + QoS rule.
3. This opens a window; in that window, in the Name field, enter the name of the quality of service rule.
4. In the Classifier drop-down list, select the created traffic classifier that you want to use in the quality of service rule.
5. If you want the quality of service rule to limit the bandwidth for traffic processed by the traffic classifier, clear the Unlimited check box. This check box is selected by default.
6. If you cleared the Unlimited check box, configure the traffic bandwidth limit:
   1. In the MBR field, enter the maximum bit rate. Default value: 1.
   2. In the Speed type drop-down list, select the units of measurement for the maximum bit rate:
      • Kbit/sec. Default value.
      • Mbit/sec
      • Gbit/sec
   3. If in the Classifier drop-down list, you have selected a classifier of the Trust type, in the Maximum reserved bandwidth (%) column, specify the percentage of the total bit rate available to traffic classes. The sum total of the specified values must equal 100%.
7. Click Create. If you have created a quality of service rule in the SD-WAN instance template, in the upper part of the settings area, click Save to save the SD-WAN instance template settings.

The quality of service rule is created and displayed in the table.

You can specify a quality of service rule when you create or edit a transport service to make the transport service use this quality of service rule.
