3. Click Save & Deploy to commit the service chaining of the 3rd party VNFs on the Versa FlexVNF.

Creating a Post-Staging Service-Chain Workflow 

Follow these steps to create a post-staging service chain workflow on per tenant basis:

1. Select Versa Director>Workflows > Template > Templates and click to Create Template.
2. Select the Interfaces tab and provide the LAN and WAN interfaces details. Refer Configuring interfaces and networks for SD-WAN controller (Versa FlexVNF Advanced SD-WAN Configuration Guide) on how to configure LAN and WAN interfaces.
3. Select the Services tab and associate the respective service chain workflow across the tenant and click Recreate. select the service chain and associate it to the provider tenant when the template has both provider and customer tenant.
   
   

Adding Devices to the Device Template

Follow these steps to add devices to the device template:

1. Select Versa Director > Workflows > Devices > Devices and click to add a device to the device template.

2. Select the Basic tab and specify a device name and associate an organization to the device and add the device to a device group.

3. Select the Bind Data tab and user will see both the post-staging template and service-chain workflow template variables.
   
   
   

4. Specify the DHCP start and end pool address values in the DHCP server configuration running in the Control-VR. This is assigned to the management interface of the VNF provided by the VNF management interface in dhcp client mode.

Onboarding the device through Zero Touch Provisioning (ZTP)

1. Bring up the device using ZTP. Refer to URL Based Zero Touch Provisioning (Versa Device Activation and Zero Touch Provisioning Guide).
2. Reboot the device. After the device is up, the controller sends the post-staging notification to Versa Director.

3. Versa Director copies the qcow2 file to the respective device and triggers the command to start the VNF.
   NOTE: Before copying the file, Versa Director checks if the same qcow2 file exists in the device (in the directory /home/versa/images), in which case it does not overwrite the existing file.

Verifying the uCPE Configuration 

Follow these steps to verify the configuration of uCPE in the Versa FlexVNF:

1. Select Versa Director >Administration > Appliances to view the list of appliances configured on the Versa FlexVNF.
   The dashboard will now have a new entry for the uCPE added in the previous section.
   
   

Monitoring uCPE 

Follow these steps to monitor the uCPE on the Versa FlexVNF:

1. Select Versa Director > Monitor > Org > Devices > uCPE to view the uCPEs statistics.
   
   
   
2. Select the Guest VNFs tab in the dashboard to view the details of the onboarded uCPE.
   
   
   

   The dashboard displays these two graphs:

Versa-virtmgr also depends on the services versa-virtlogd and versa-virtlockd. Check the status of these services in the vsh status output. If this fails to come up, start the services manually.

The following output appears:

Alarms are generated for the data-path reachability between Versa VNF and the third-party VNF. Monitoring is triggered only if bypass-on-fail is generated under the org-level service-chain-instance.
