Python for Network Automation (PNA)

 

Course Overview

Managing networks can be repetitive and error-prone, but Python can make incredible changes to how you automate with all major (and most minor) network vendors! This course is driven by lessons and labs designed to utilize Python libraries designed to interact with and configure your network devices. At the conclusion of this course, you’ll be empowered with the tools and skills necessary to take your network to the next level. This class is a combination of live demonstrations and hands-on labs with virtual network devices and endpoints as targets for your configuration.

Who should attend

This course was written for networking professionals looking to expand their capabilities by automating their workload with Python. This includes: Network Engineers, Network Architects, System Admins, DevOps Engineers, Cisco Certified Professionals (CCNA, CCNP, CCIE), and developers interested in network programmability with Python.

Prerequisites

Keyboard proficiency, and some basic understanding of network concepts is the only hard requirement. Students with some previous exposure to Python, any other scripting experience, will take the most from the course. In lieu of any scripting experience, Alta3 Research’s Python Basics course is recommended.
