Cisco Viptela SDWAN : Two Control Commands

We are come here again with some of the interesting commands used in the Cisco Viptela devices for control plane check. These are important commands to check the status and further troubleshoot the issues you are facing in Cisco Viptela SDWAN infrastructure.

Command no 1: Control Local Properties

  • show control local-properties wan-interface-list on vEdge 
  • show sdwan local-properties on cEdge

To check the status of the WAN interfaces with all the parameters configured on a vEdge you can test the below command and it will give you the result shown below

On the vEdge (Viptela Devices)

On the cEdge (Cisco Devices)

Note ⭐ The command show control local-properties wan-interface-list will provide you the output of Network Address Translation (NAT) Type. 

When the vEdge/cEdge is behind a NAT device (Firewall, Router, etc), Public and Private IPv4 address, Public and Private source User Datagram Protocol (UDP) ports are used to build the data plane tunnels. 

You can also find the state of the tunnel interface, color and the maximum number of control connections configured.

Command no 2: Control Connections

  • show control connections on vEdge 
  • show sdwan control connections on cEdge
Make sure you check that the color that does not form data plane tunnels does have a control connection established with the controllers in the overlay. cEdge/vEdge does not send the Transport Locator (TLOC) information to the vSmart via Overlay Management Protocol (OMP)

On the cEdge (Cisco Devices)

Note ⭐ If the interface that does not form data tunnels,  you can do that with the work around by setting the max-control-connections 0 in the selected interface under the tunnel interface section.
