Services – Manage VLE - Virtual Link Extension


Manage VLE


Selecting Manager → Services → Manage VLE displays the Manage VLE  dashboard with a list of any existing VLE settings.



A Virtual Link Extension (VLE) is a logical link or tunnel.  A VLE connect ports within a switch, or from a port on one switch to a port on a switch in another cluster.


The VLE feature requires that a Layer-3 fabric must be deployed from an UNUM Layer-3 Playbook.  If you have an existing Layer-3 fabric (i.e. built with the CLI or built prior to UNUM 5.0.0) where you wish to use VLE, the VXLAN tunnels will have to be built and configured.  Please contact Pluribus Networks technical support.

 

The workflow in building a VLE involves four basic steps:

 


Configuration Note: Whenever possible, physically cabling the devices to be connected to their respective ports before creating the VLE simplifies the process.


 

  1. Use  Manager → Services → VLE → Manage VLE to create a VLE. To add a VLE click Create Virtual Link Extension. The VLE Connection dashboard opens and you enter the desired configuration parameters.
    • Provide a meaningful name, such as Leaf1p30-L3p30, where the VLE will connect Leaf1, Port 30 to Leaf3, Port30.
    • When creating the VLE, each requires a unique vlan and vxlan identifier, e.g. VLAN 30, VXLAN 10030.
  1. Verify the port state is up via the Port Status dashboard (Manager → Layer 1 → PHYSICAL PORTS → Port Status).
  2. Complete the connection between devices by cabling both ends of the VLE to their respective devices (unless this was already done).
  3. Trigger a VLE discovery from the VLE Overlay (Overlay → Overlay details → Gear button → Trigger VLE discovery).

 

At this point the VLE inter-link connection in the ring diagram updates reflecting the new VLE connection. Changes in the inter-link visual indicators from Green to Red, or vice versa, indicate whether ports are "up" or down".  In either case, the VLE is created and displayed in the dashboard. Bringing the ports "up" and ensuring the Tunnel is "up" changes the VLE status to Up. If the inter-link connection stays Red, please verify that the port(s) state is up and the respective devices are connected and active.



UNUM provides access to specific feature help documentation via the Help Button  icon.


Select the desired Fabric from the left side navigation bar and the dashboard updates showing all VLE entries from all switches within the Fabric.



Note: If no entries exist a "No Data Exists" message is displayed. You must first configure an entry on a switch. Prerequisite settings and configuration may be required.



The dashboard displays a list of existing VLE entries.


Additional parameters include: Name, Node 1, Node 2, Node 1 Port, Node 2 Port, Status and Tracking.


You sort the list of entries in the dashboard using the up / down  arrows above each of the columns to sort the information as needed.

  • Node 1 (required) - VLE node 1
  • Node 2 (required) - VLE node 2
  • Port 1 (required) - node-1 port of VLE
  • Port 2 (required) - node-2 port of VLE

The new VLE appears in the dashboard. If the tunnel and selected ports are "up" the Status will appear as up. Otherwise the Status shows down.


In this event ensure the ports are physically connected to the switch and the tunnel is functioning. When these conditions are met the dashboard updates accordingly.
