In Detail
The days of configuring Cisco networks only with the command-line interface (CLI) are ending. Do you want to program networks using Python, but not sure where to start? Well, this course will show you how you can start programming Cisco networks using Python within 20 minutes.
The course begins by explaining the steps for setting up the lab and takes you through the concepts of network automation. Once you are ready with the environment and the basics, you will dive into automating networks. You will learn how to automate networks using Telnet, Secure Shell (SSH), Paramiko, Netmiko, and Network Automation and Programmability Abstraction Layer with Multivendor support (NAPALM). In the rest of the course, you will learn the various concepts of Python needed to automate the configuration of network devices.
By the end of this course, you will be able to program networks and network devices using Python 3 and Graphical Network Simulator-3 (GNS3).
Who this book is for
This course is for network engineers, network architects, and for those who are looking to apply Python programming to network automation. Basic understanding of networking knowledge (CCNA) and Graphical Network Simulator-3 (GNS3) is needed to get started with this course.
