Which protocol is used for the vManage to connect to the vSmart Controller hosted in Cloud?

PnP Server is a component used for automated onboarding of physical devices, not a communication protocol for vManage to vSmart controller interaction.

ZTP (Zero Touch Provisioning) is a method for automated device onboarding, not a communication protocol between established controllers.

vManage uses NETCONF (Network Configuration Protocol) to connect to and manage vSmart Controllers, including those hosted in the cloud. NETCONF is an XML-based protocol that provides a programmatic interface for installing, manipulating, and deleting configuration data, enabling vManage to effectively push configurations and policies to the vSmart controllers.

HTTP is primarily used for web browser access to vManage's graphical user interface, not for the underlying programmatic configuration communication between vManage and vSmart controllers.
