Netmiko By Example Course


Student Success

  • 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 have taken several paid and non-paid Python courses. I can say that by far your course is the best one I have taken. The way you explained stuff just makes sense to me.

  • 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!

FAQ

What is the format of the course?

This course is a twelve lesson, six-week email course. The lessons are sent every Tuesday and Thursday. The lessons contain videos, exercises, and additional content. We have posted solutions to the exercises online. There also is a community forum where you can ask questions, post code, and interact with other students.

Is there a lab environment?

Yes, the lab environment will consist of a set of virtual and physical network devices and at least one AWS-Linux server. We will install a set of libraries in the lab environment; this will enable you to get working quickly. The lab environment will have a mixture of vendors and platforms (Cisco IOS/IOS-XE, Cisco NX-OS, Juniper, and Arista).

What are the prerequisites for the course?

You should be familiar with the basics of Python. You can be slow at writing Python code, but these ideas should not be new to you.

You also need to be familiar with basic network engineering (routing, switching, Cisco CLI configuration).

Finally, since the lab environment will use Linux. You should be at least somewhat familiar with Linux. You should know the basics of how to move around the file system, execute a script, and edit a file.

What is Netmiko and why should I care?

Netmiko is a Python library that simplifies automating legacy devices using SSH. Netmiko supports a very broad-set of networking platforms and also enables the use of fairly simple code patterns for automation.

What is the community forum?

The community forum is a forum where students can interact, post code, ask questions, and make recommendations.

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

If you are not satisfied with the course, there is a 30-day money back guarantee. No questions asked.
