Student Testimonials



I really like the hands-on nature of the course with a lab environment to create and test code. I have used Python and Netmiko at scale in my work, but it is always good to learn important details about the library especially from the developer himself.

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. For the Plus Package, there are two additional bonus lessons covering Netmiko4 features and 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. Students that purchase the Plus Package will have access to the community forum for the duration of the course.

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

If you are not satisfied with the course, there is a 20-day money back guarantee (from the start of the course). No questions asked.
