Abstract

This chapter is focused on SDN practical approach with Cisco controllers APIC, APIC-EM, and the application programming interfaces with real-world benefits and challenges. The chapter uses Cisco SDN way of managing, administering, maintaining, and implementing platforms using an external tool. This chapter will also discuss the controller API structures, management model of the controller, and using POSTMAN tool to push API requests and talk to the APIC controller.
