Creating a fabric intent using a manual topology

Before you create a new fabric intent based on a manually configured topology file, ensure you have done the following:

  • Created a region to which the fabric can belong; see Creating a region.
  • Imported a JSON file that describes the topology into the Fabric Services System.
This procedure describes how to create a fabric intent based on a previously defined topology that is described in a JSON file.
  1. Click to open the main menu.
  2. In the main menu, select Fabric Intents.
  3. Click the + CREATE A FABRIC INTENT button.
    Templates are displayed in a grid view by default. To switch to the list view, select in the template selection screen. Click to return to the grid view.
  4. Select the Imported Fabric Design / Manual Topology template.
  5. Click the CREATE button.
  6. On the left-side panel, enter or select the basic parameters that define your intended fabric as described in Basic parameters for manual topology fabric intent.
    At the top of the left-side panel, the name of the template you selected in step 4 is displayed as the "Reference Template".
  7. Optionally, select an ASN pool and IP pools other than the default pools for the region as described in Optional parameters for fabric intents:
    • ASN Pool Name
    • Inter Switch Link Pool Name
    • Management Pool Name
    • System Pool Name
  8. Click to save the fabric intent. When you save the fabric intent, the system:
    • updates the state of the fabric intent to Created.
    • updates the version number of the fabric intent to 1.0.
    • enables the GENERATE FABRIC button.
  9. Click GENERATE FABRIC.
The system generates a recommended topology for your fabric based on the template you selected and the parameters you provided.

When generating the topology, the system also generates the various cable connections and the individual node configurations required to support this fabric topology.

During fabric generation, the fabric intent state advances through the following:

  • Cable Map in Progress
  • Config Generation in Progress
  • Configuration Generated

After the generation is complete, the resulting topology displays in the main area of the Fabric Intents page.
