Cisco Automation for NetDevOps

Transform Your Enterprise Infrastructure into a Self-Healing Automated Pipeline

The 2026 networking landscape requires more than just typing commands into a terminal. It demands speed, scalability, and absolute precision. Cisco Automation for NetDevOps is your comprehensive, project-first guide to modernizing your operations.

This book avoids heavy theoretical discussions, prioritizing hands-on tutorials and direct code implementation. You will learn by building. Starting from a completely blank directory, you will construct an isolated development sandbox, write resilient Python scripts, and ultimately design a fully autonomous continuous integration and continuous delivery pipeline. Whether you are connecting to legacy Catalyst switches or modern centralized controllers, this manual provides the exact workflows required to eliminate human error and deploy network changes safely.

• Development Sandboxes Create reproducible testing environments using Docker containers and Python virtual environments.
• Version Control Systems Implement Git branching strategies to track configurations and manage collaborative staging environments.
• Data Manipulation Parse raw telemetry and configuration payloads using JSON, XML, and YAML natively in Python.
• Legacy Hardware Automation Establish secure, automated bulk deployments across traditional switches using Netmiko.
• Multi-Vendor Standardization Utilize NAPALM to abstract proprietary operating systems and detect configuration drift.
• Model-Driven Programmability Transition to structured RESTCONF operations and YANG data models for precise device management.
• Automated State Validation Rely on the Cisco pyATS framework to mathematically verify routing tables and interface health.
• Declarative Policies Write idempotent Ansible playbooks and Jinja2 templates to enforce baseline global device configurations.
• Centralized Orchestration Automate zero-touch provisioning and network fabric deployments using Catalyst Center APIs.
• The Ultimate CI/CD Pipeline Connect Git repositories to automated runners that execute tests, push configurations, trigger self-healing rollbacks, and stream real-time ChatOps notifications to your team.

This hands-on guide is engineered for network administrators and systems engineers who want to stop repeating manual tasks and start operating as developers. If you are ready to treat your network as code, this practical roadmap will take you from the absolute basics to production-ready deployments.
