Creating a QoS rule

Expand all | Collapse all

You can create a QoS rule in an already deployed SD-WAN instance or in an SD-WAN instance template. If you create a QoS rule in an SD-WAN instance template and use that template to deploy an individual instance, the same QoS rule is automatically created in the deployed instance.

Before creating a QoS rule, you must create a traffic classifier.

To create a QoS rule, use the following instructions:

  • Creating a QoS rule in an already deployed SD-WAN instance.

    To create a QoS rule in an already deployed SD-WAN instance:

    1. In the menu, go to the Infrastructure section.

      The SD-WAN infrastructure management page is displayed. By default, the Network resources tab is selected, which displays the table of SD-WAN Controllers.

    2. Click Management next to the SD-WAN Controller and in the drop-down list, select Configuration menu.

      This opens the SD-WAN Controller configuration menu. By default, you are taken to the Controller nodes section, which displays a table of Controller nodes.

    3. Go to the QoS section.

      The Traffic classes tab, which is selected by default, displays the table of traffic classes.

    4. Select the QoS rules tab.

      A table of QoS rules is displayed.

    5. Click + QoS rule.
    6. This opens a window; in that window, in the Name field, enter the name of the QoS rule.
    7. In the Classifier drop-down list, select the previously created traffic classifier that you want to use in the QoS rule.
    8. Configure traffic bandwidth limiting:
      • If you do not want to limit the bandwidth of traffic processed by the previously selected classifier, select the Unlimited check box.
      • If you want to limit the bandwidth of traffic processed by the previously selected classifier, clear the Unlimited check box.

      This check box is selected by default.

      QoS rules that do not limit traffic bandwidth provide users with the highest network performance, especially when dealing with applications and services with high bandwidth requirements. However, if your network is not resource-rich, bandwidth limiting may help avoid issues with congestion, performance, and traffic filtering for applications that have different priorities.

    9. If you cleared the Unlimited check box, configure the traffic bandwidth limiting settings:
      1. In the MBR field, enter the maximum bit rate. The default setting is 1.
      2. In the Speed type drop-down list, select the units of measurement for the maximum bit rate:
        • Kbit/s (selected by default)
        • Mbit/s
        • Gbit/s
      3. If you have selected a classifier of the Trust type in the Classifier drop-down list, in the Classifier drop-down list, in the Maximum reserved bandwidth (%) column, specify the percentage of the total bit rate available to each class. The sum total of the values specified for each class must equal 100%.
    10. Click Create.

    The QoS rule is created and displayed in the table.

  • Creating a QoS rule in an SD-WAN instance template.

    To create a QoS rule in an SD-WAN instance template:

    1. In the menu, go to the SD-WAN → SD-WAN instance templates subsection.

      A table of SD-WAN instance templates is displayed.

    2. Click the SD-WAN Instance template.

      The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand button .

    3. Select the QoS rules tab.

      A table of QoS rules is displayed.

    4. Click + QoS rule.
    5. This opens a window; in that window, in the Name field, enter the name of the QoS rule.
    6. In the Classifier drop-down list, select the previously created traffic classifier that you want to use in the QoS rule.
    7. Configure traffic bandwidth limiting:
      • If you do not want to limit the bandwidth of traffic processed by the previously selected classifier, select the Unlimited check box.
      • If you want to limit the bandwidth of traffic processed by the previously selected classifier, clear the Unlimited check box.

      This check box is selected by default.

      QoS rules that do not limit traffic bandwidth provide users with the highest network performance, especially when dealing with applications and services with high bandwidth requirements. However, if your network is not resource-rich, bandwidth limiting may help avoid issues with congestion, performance, and traffic filtering for applications that have different priorities.

    8. If you cleared the Unlimited check box, configure the traffic bandwidth limiting settings:
      1. In the MBR field, enter the maximum bit rate. The default setting is 1.
      2. In the Speed type drop-down list, select the units of measurement for the maximum bit rate:
        • Kbit/s (selected by default)
        • Mbit/s
        • Gbit/s
      3. If you have selected a classifier of the Trust type in the Classifier drop-down list, in the Classifier drop-down list, in the Maximum reserved bandwidth (%) column, specify the percentage of the total bit rate available to each class. The sum total of the values specified for each class must equal 100%.
    9. Click Create.

      The QoS rule is created and displayed in the table.

    10. In the upper part of the settings area, click Save to save the configuration of the SD-WAN instance template.
