Performing Layer 3 Fabric Connectivity Checks

After you have deployed a Layer 3 Fabric, you can run connectivity checks to troubleshoot any connectivity issues in the fabric. You can initiate a connectivity check from the Manage Layer 3 Fabrics page. Network Director uses LLDP to check the connectivity of each device with the device’s neighbor and compares it with the recommended cabling plan and reports the results in the Cabling Check Results page.


Network Director performs connectivity check only for the devices that are scheduled for immediate deployment and not for devices that are reserved for the future.

The Cabling Check Results page contains three tabs—Unknown Devices, Devices with Cabling Faults, and Devices Connected Properly. Each of these tabs displays a graphical representation and a grid view of each leaf device with the corresponding details. To switch between the Graphical view and the Grid view, toggle the Switch to Grid View and Switch to Graph View buttons.

From the Cabling Check Results page, you can:

  1. Click the Unknown Devices tab to view the devices that are part of the Layer 3 Fabric, but are not physically connected to the network and have not undergone zero touch provisioning. Click each leaf device listed in the Devices box to see a detailed view of the device with the connections as per the cabling plan.

  2. Click the Cabling Faults tab to view the devices which did not adhere to the recommended cabling plan. This might be because of missing connections or additional connections. You can view the details section to identify the faulty connections for each device.

  3. Click Devices Connected Properly tab to view details of devices that are connected as per the cabling plan. Click each device to see the connections.

  4. Click Export Results to PDF to export the connectivity check results as a PDF file.

  5. Click OK to close the Cabling Check Results page.
