Creating and managing QoS profiles

QoS profiles allow you to shape the traffic managed by a workload intent, as described in QoS profiles.

In the Fabric Services System UI, you can:

  • Create a QoS profile
  • Edit a QoS profile
  • Delete a QoS profile

Creating a QoS profile

  1. If you are not already on the Profiles page, do the following:
    • Click to open the main menu.
    • Select Profiles.
    The Profiles page displays.
  2. From the Profiles drop-down, select QoS.
  3. Click + CREATE A QOS PROFILE.
  4. Enter general information about the QoS profile.
    1. Enter a Name for the profile.
    2. Optionally, enter a Description.
  5. Enter Classifier data for the QoS profile.
    1. In the Classifiers panel, click + DSCP POLICY.
      The Add DSCP Policy dialog displays.
    2. Select a Value and Forwarding Class for the policy.
    3. Click ADD.
      The system adds the DSCP policy to the Classifiers list.
    4. If required, you can delete an individual DSCP policy from the list by clicking on the More actions icon ( ) at the right of the policy's row, and selecting Delete... from the displayed list.
    Repeat this step until the Classifiers list is complete.
  6. Enter Rewrite Rules for the QoS profile.
    Repeat this step until the DSCP Policy list is complete.
    1. In the Rewrite Rule panel, click + QOS MAPPING. The Add QoS Mapping dialog displays.
    2. Select a Forwarding Class and DSCP for the mapping entry.
    3. Click ADD. The system adds the DSCP policy to the Classifiers list.
    4. If required, you can delete an individual DSCP policy from the list by clicking on the more icon ( ) at the right of the policy's row, and selecting Delete... from the displayed list.
    Note that the Workload Reference List is empty. This list shows all of the workload intents that are currently using this global QoS profile; but because this is a new profile, no workload intents are using it.
  7. At the lower right of the QoS overlay, click CREATE.
    The system closes the Create QoS Profile overlay and returns you to the Profiles page with the QoS view selected. The profile you just defined is now included in the list of available QoS profiles.

Editing a QoS profile

You can edit a QoS profile at any time.

If the QoS profile you edit is already being used by a workload intent, and that workload intent has already been generated or deployed, then the changes you make do not propagate to the workload intent until you regenerate that workload intent:

  • If the workload intent has been generated, but is not yet deployed, you can re-save and regenerate the workload intent without creating a new version. Regenerating the workload intent incorporates the new QoS settings into its configuration.
  • If the workload intent has already been deployed, you must create a new candidate version of the workload intent before you can regenerate and redeploy it with the new QoS settings.
  1. If you are not already on the Profiles page, do the following:
    1. Click to open the main menu.
    2. Select Profiles.
  2. From the Profiles drop-down, select QoS.
  3. Select a QoS profile from the list.
  4. Click the More actions icon ( ) at the right edge of the row, and select Open from the drop-down list.
  5. Update parameters in the QoS profile as described in Creating a QoS profile.
  6. At the lower right of the QoS overlay, click SAVE.

Deleting a QoS profile

You can delete a QoS profile provided it has not been used in a workload intent. If you try to delete a QoS profile that is in use, the system prevents the action and displays a message indicating why the profile cannot be deleted.
  1. If you are not already on the Profiles page, do the following:
    1. Click to open the main menu.
    2. Select Profiles.
  2. From the Profiles drop-down, select QoS.
  3. Select a QoS profile from the list, click the More actions icon ( ) at the right edge of the row, and select Delete... from the drop-down list.
  4. In the confirmation dialog, click OK.
The system deletes the selected profile and closes the confirmation dialog, returning you to the Profiles page with the QoS view selected. The profile you just deleted no longer appears in the list.
