Study Guide

Objective

The goal of this workshop is to introduce the students to the concepts and techniques for programming a network device. Upon completion of the workshop, students will be able to:
- Understand the value, set-up and use of software concepts and tools relevant to network programmability (Python scripting, Git, JSON, Postman, APIs).
- Describe a different approach to software-defined networking (SDN), including central application policy control.
- Create simple applications in Python with REST APIs.
- Use the Cisco DevNet Sandbox to interact with programmable devices using real-world APIs on Cisco APIC-EM programmable controllers.
- Create a variety of programs to interact with the Cisco APIC-EM APIs.
