Creating a configuration override

if you are going to specify the target nodes by label, you should already have created and applied that label to the target nodes as described in Labels
This procedure describes how to create the initial version of a configuration override.
  1. Click the menu.
  2. Select Overrides to open the Overrides page.
  3. Click +CREATE to open the Configuration Creation page.
  4. Enter parameters for the following as described in Configuration override parameters:
    • Active
    • Name
    • Description
    Note: The Version property is automatically set to 1 and cannot be altered.
  5. For Method for Selecting Nodes, do one of the following:
    • To specify the target nodes by a label they share, select By Label and go to step 6.
    • To select one or more nodes directly from the inventory, select By Node and go to step 7.
  6. Select the Edit icon () above the Node Label Selector panel to open the Label Picker form and do the following:
    1. Ensure that you have created a label with the Label Key "Node-type" and applied that label to all of the nodes whose configurations you plan to override.
      Note: Procedures for creating and applying labels to objects can be found in Labels and are beyond the scope of this procedure.
    2. Select the label with the Label Key "Node-type" from the displayed list of labels.
    3. Click the + icon beside the label name to add it to the panel at the top of the Label Picker form.
    4. Continue selecting labels and adding them to the top panel until you have selected all of the labels for nodes whose configuration you want to override.
    5. Click SAVE.
      The Label Picker form closes and you are returned ot the Create Override page. The label or labels you selected are displayed in the Node Label Selector panel.
    6. Go to step 8.
  7. Select the edit icon () above the Node Selector panel to open the Node Selector and do the following:
    1. Check the box at the left edge of the row for each node whose configuration you plan to override.
    2. Click ADD.
      The Label Picker form closes and you are returned ot the Create Override page. The node or nodes you selected are displayed in the Node Label Selector panel.
  8. Set an Execution Order value for this override.
  9. Set a Target Configuration by clicking ADD, leaving the default values in the resulting Target Configuration form, and clicking ADD to close the form.
  10. In the Configuration panel, add the lines of JSON configuration data that you want to be merged into the configurations for the targeted nodes.
  11. Click the Save icon () to save the new override.

If you created the configuration override in the midst of creating the a fabric intent, some of the node data within that fabric intent has been updated based on the new data contained in the configuration override. You can now resume the creation and deployment of that fabric intent.
