Hands-On Cisco Automation with Python

Learn how to simplify Cisco network management with practical Python automation.

Modern networks demand speed, accuracy, and scalability. Hands-On Cisco Automation with Python teaches network professionals how to automate common Cisco IOS tasks using Python and three widely adopted tools: Netmiko, NAPALM, and Nornir.

This practical, example-driven guide shows how to replace repetitive manual work with reusable scripts that configure devices, collect operational data, and validate network state. Readers follow clear, step-by-step examples that explain both the Python code and the Cisco IOS commands involved.

The book focuses on real-world automation, not theory, making it ideal for readers new to network automation who want immediate, usable results.

What You’ll Learn

• Automate Cisco IOS access and command execution with Python
• Manage and validate configurations using NAPALM
• Scale automation across multiple devices with Nornir
• Work with structured data such as JSON and Python dictionaries
• Build reusable scripts to improve consistency and reduce errors

Who This Book Is For

• Network engineers and administrators
• CCNA and early-career networking professionals
• IT practitioners transitioning into automation
• Anyone managing Cisco IOS-based networks
