Which protocol does vManage use to provision the WAN Edge device during the onboarding process?

RESTCONF is an HTTP-based alternative to NETCONF but is not the protocol vManage relies on to provision WAN Edge devices during onboarding.

NETCONF is the network configuration protocol that vManage uses to push device configurations to WAN Edge routers after authentication and onboarding are complete. It operates over SSH and uses YANG data models to deliver structured configuration payloads, providing a reliable and transactional mechanism for provisioning Cisco SD-WAN WAN Edge devices at scale.

SPP (Secure Provisioning Protocol) is not the protocol used by vManage for WAN Edge device provisioning in the SD-WAN architecture.

HTTPS is the transport used for the vManage web interface and REST API access, but it is not the provisioning protocol used to push configurations to WAN Edge devices.
