Description

Network automation offers a powerful new way of changing your infrastructure network. Gone are the days of manually logging on to different devices to type the same configuration commands over and over again. With this book, you'll find out how you can automate your network infrastructure using Python. You'll get started on your network automation journey with a hands-on introduction to the network programming basics to complement your infrastructure knowledge. You'll learn how to tackle different aspects of network automation using Python programming and a variety of open source libraries. In the book, you'll learn everything from templating, testing, and deploying your configuration on a device-by-device basis to using high-level REST APIs to manage your cloud-based infrastructure. Finally, you'll see how to automate network security with Cisco’s Firepower APIs. By the end of this Python network programming book, you'll have not only gained a holistic overview of the different methods to automate the configuration and maintenance of network devices, but also learned how to automate simple to complex networking tasks and overcome common network programming challenges.

What you will learn

Programmatically connect to network devices using SSH (secure shell) to execute commands

Create complex configuration templates using Python

Manage multi-vendor or multi-device environments using network controller APIs or unified interfaces

Use model-driven programmability to retrieve and change device configurations

Discover how to automate post modification network infrastructure tests

Automate your network security using Python and Firepower APIs

This book does a good job of introducing beginner and intermediate Python, but goes on to really shine when it covers popular and lesser-known network tools using Python: using SSH with Paramiko, Jinja 2, Netmiko, Netconf, ncclient, and more. Almost every chapter has sections that start with "how to do it" and "how it works". Clearly the author has been a network engineer and is sharing their extensive knowledge.

I'm the technical reviewer of this book. This book covers all the basic and advanced topics about Netdevops, most of the scripts in this books are run and demonstrated on Cisco devices.You may find out that you are already familiar with some of the chapters in this book such as Paramiko and Netmiko as they are the most famous and most popular modules for network engineers who already have some basic knowledge about Python. Besides that, Marcel did a great job introducing the powerful but less well-known Netdevops tools such as Jinja2, NETCONF, RESTCONF, pyATS/Genie, EC2 (for AWS Cloud Networking automation) and Firepower API.I highly recommend this book to network engineers who want to develop the necessary skills and maintain a cutting edge in this Netdevops era, no matter if you are a newbie or seasoned network engineer.

The book is dedicated to CISCO network engineers that need to know Python to deliver certain milestones. The book is also great for new devops, if they do not necessarily have a lot of experience with network programming (though I would assume that's not the case anymore.The book starts gently with a primer on Python which can be easily skipped if you are already versatile in Python. The primer is well done, but it would but it is recommended that you run at least some of the code snippets provided so you get the gist of how Python works.Once the introduction is out of the way, the book delves straight into networks programming topics like connecting via SSH to other devices with Paramiko, Jinja 2 configuration or network devices configuration with Netmiko, netconf config, etc. The approach for these chapters is very hands-on, code-focused, therefore more technical, as opposed to the images heavy approach of the early technical books on the subject. It is assumed you have some knowledge about networks. If you do not have that knowledge, it would be best to get it from another book.The last two thirds of the books are getting into the meat of the subject with complex configs with NAPALSM, automated test deployments with Genie(especially import for devops), configuring devices with a REST interface, consuming high-level networking APIs with requests, custom Ansible modules, AWS infrastructure, etc. This section of the book will help you decide if you want to continue being a network engineer or if you want to take on a more traditional development role like devops (well, yes the devops as a job exists for a decade, but such jobs of maintaining and running online systems existed for decades in some capacity).Overall a great book that can fill in your missing knowledge or help you decide which career path you would like to follow!

A cookbook-style reference, Python Network Programming Techniques provides the reader with introductory material, step-by-step instructions, and an explanatory section for each “recipe”. The book walks the reader through a Python 3 refresher, then moves on to basic connectivity via the Paramiko SSH library; a detour through Jinja (which is used later on) is followed by a very logical progression through Netmiko, NETCONF, Napalm, and the HTTP/REST-based engines. Ansible and cloud services via AWS are also covered in easily-followed procedures. The explanatory material is more than sufficent to ensure that even readers with little or no experience can get up and running with the tools.Engineers wanting to script configuration and maintenance tasks will find the book useful right from the start. There are some hidden gems here; a nice explanation of Python variadic arguments (for those who were a little weak in that area), great coverage of the oddly-named YANG (Yet Another Next Generation) modeling language standard, and some quick-and-dirty tricks with pyATS / Genie that will come in handy for many routine tasks.The book tends to be rather Cisco-specific in places, and if you’re going to follow along, you will need some resources to play with. For the first few chapters, a Raspberry PI and a low-end Cisco router will suffice, but later on an AWS account, Meraki, Ansible, and Firepower will be necessary. A couple of the examples may leave you scratching your head a bit due to minor typos and such but figuring those out ends up being good practice.All in all, Python Network Programming Techniques nicely fills an important gap between the Python and network-management worlds. Those wanting to automate their network configuration and management tasks will find it a readable, practical, and quite useful resource.
