Fabrics

Fabrics are a collection of network devices, network configurations, network profiles, and external connections.

A Fabric is required before setting up a switch out of band subnet and a network device.

To set up a Fabric, go to the Fabric Manager, click on Fabrics, and click on Add Fabric.

In the box, fill in the Name, Description, select the site, and Fabric Type (currently, Ethernet is the only supported option).

The Fabric is currently in Draft. In this state, the fabric is not available for use. Changing it to Active will make it available for use. To do this, click on Fabrics, click on the fabric, click on Fabric Settings, and click on Activate.

At this point, set up the switch out of band subnet and the network device that will be associated with the fabric.

Once these are set up, click on the fabric to edit it. To add a network device, click on Topology, Add Element, Network Device, select the network device, and click Add Network Device. Repeat for all network devices you wish to add.

Once the network devices are added, they can be deleted from the fabric by clicking on the network device in the Topology and clicking delete.

Click on the Fabric, then Topology to:

• Modify the Topology - Add/Delete network devices and modify links

Click on the Fabric, then Logical Networks to:

• Add Public Logical Network
• Edit existing Logical Networks

Click on the Fabric, then Logical Networks to:

• Add Network Profile

Click on the Fabric, then External Connections to:

• Add External Connection

Click on Fabric Settings to change the configuration of the fabric. Under Fabric Settings/General you can:

• Site - The site this fabric will be assigned to
• External ID - The external identifier for this fabric on the controller
• Use DPU Mode If Available - Enable DPU mode when a DPU is available on the fabric.

Under Fabric Settings/Vlan Configuration you can:

• Modify Logical Network VLAN Auto-Allocation Range
• Modify L3 VNI VLAN Auto-Allocation Range
• Modify Reserved VLANs
• Modify Prevent VLAN Cleanup

Under Fabric Settings/VNI Configuration you can:

• Modify L2 VNI Prefix
• Modify L3 VNI Prefix

Under Fabric Settings/Link Aggregation Configuration you can:

• Modify LAG Ranges

At the top level of Fabrics, you can tick the fabrics you wish to delete and click on Bulk Operations/Delete to delete the fabric.

To manage Fabric interconnects, click on Fabrics/Interconnects. From here you can:

• Add/Delete and Manage Fabric Interconnects

In the main Fabric Manager, you can further: Click on Route Domains to manage route domains for L3 isolation. Click on BGP Sessions and Link Aggregations to manage BGP sessions and link aggregations on the fabric links.

Re-scanning fabric links

To refresh the link discovery for a fabric (for example after adding or removing physical cables), use the rescan action:

curl -X POST "https://<your-server>/api/v2/network-fabrics/{networkFabricId}/actions/rescan-links" \
  -H "Authorization: Bearer <API_KEY>"
