What is the role of DNA Center in SD-Access?

 DNA Center is the central point of management for SD-Access. It provides a graphical user interface (GUI) to design, provision, and monitor the SD-Access fabric. DNA Center also offers various service applications that leverage the network data and analytics to provide insights, automation, and assurance for the network and the applications running on it. DNA Center does not perform the functions of identifying and authenticating endpoints, which are handled by ISE; nor does it act as the point of exchange of reachability and policy for two domains, which are the roles of the border nodes and the control plane nodes; nor does it maintain a database of endpoint IDs to fabric edge nodes, which is the function of the LISP mapping system. References:
