Manage SD-WAN templates, policy and health Select the Manager in your lab and open its web interface. Check the edge details for its control connections and OMP peer. Create a CLI template and use a variable for the device hostname. Create an NTP feature template for this supported IOS XE target. Combine the CLI and feature templates in a device template. Select the target carefully, because a push replaces its configuration. A missing variable is refused before the configuration can be applied. Preview the generated commands and confirm the selected device and values. Push the template, then check its running configuration and the control device. Save the configuration and reopen the lab to verify the change. For the policy test, first confirm that both service VPN destinations respond. Create a rule for one prefix and inspect the compiled policy preview. Apply the control policy through the supported Manager API. The selected destination is blocked while the control destination still responds. Reverse the rule and verify that its route and traffic recover. In Monitor, follow the voice path as MPLS fails and business internet takes over. Restore the transport and check that the voice path returns to MPLS.
