Student Success

  • I decided to take Kirk's courses on Ansible and Nornir during the stay-at-home-orders in 2020 when COVID-19 hit the world. After the first few lessons I was able to write my first script to check for and add VLANs to our NX-OS environment.

  • I highly recommend both courses (Ansible and Netmiko) for those looking to learn more about network automation. Kirk Byers does a great job at explaining the content, provides the lab resources required to perform the course material, and is good at responding to questions on his Slack Channel.

  • I am on the material for the 3rd week and I just wanted to compliment you on the way that you explained how to unwrap the data structures. Best step by step explanation I have seen so far to help me understand and work with the data. Thank you very much!

What is the format of the course?

This course is a ten week email-course. Each week you will receive a lesson that contains a set of videos, some additional content, and some exercises. I will post solutions to the exercises online. The course is largely self-paced except for the weekly email cadence.

Is there a lab environment?

No, since this is a free course, there is no lab environment. For all of the lessons you should be able to accomplish the lessons without having any access to network devices.

What are the prerequisites for the course?

This course is intended for network engineers that have some basic familiarity with programming (for example, Perl, shell scripting, other language) and who would like to learn Python. The course covers Python fundamentals, but using examples and exercises that are more relevant to network engineers.

Why Python?

Python facilitates writing clean, readable code and is natively present on Linux and MacOS. Python has gained widespread support in the networking community both from engineers and from vendors. Python has a large, active community and, consequently, numerous resources are available to you (libraries, documentation, books, tutorials, etc.).

What if I am unsatisfied with the course after I sign-up?

The course is free so unsubscribe from the email-list if you aren't happy with the lessons or our other content.
