Description

Learn Network Programmability and Network Automation using GNS3 and Python version 3.

This course is based on Python 3.

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 within 20 minutes.

This course was created for network engineers. There are too many other Python courses out there that try to make network engineers software developers. Instead of teaching network automation, they teach you Python theory. This course is different. 

This course is practical. I won't talk about programming in abstract terms and make you wait before you can start automating networks. I will show you how you can quickly and easily start network programming by using GNS3, Cisco IOS and Python.

You will see demonstrations of the configuration of both Cisco routers and switches in GNS3. For example, how to configure multiple VLANs on a multiple switches, or how to configure OSPF on a router and more.

This course shows you practical examples of using Python to programmatically configure Cisco network devices rather then just talking about it.

The days of configuring Cisco networks only with the command line interface (CLI) are drawing to a close. You need to add network programmability using Python and APIs to your skill set.

Learn how to automate networks using:

- Telnet

- SSH

- Paramiko

- Netmiko

- NAPALM

Tools such as NAPALM and Netmiko make it easy to configure and interact with network devices using an API such as NETCONF or using SSH. Don't reinvent the wheel. Use the tools available to you to quickly and easily automate your networks.

Some comments about the course:

"Knowing the material from just the first video would have saved me hours of work and rework in the past." 

"It's the easiest, most fun, and most valuable course I've completed yet on Python Programming for Networking. Love it! Thanks again David!!!" 

"Excellent course on Network Programming using Python with lot's of practical network configuration examples."

"Great way of explanation.Nice video and inspiring words! Thank you so much David. You are genius."

"I've been doing network automation for a while, even so, I've learned new things through this course. The instructor start from a basic example, adding improvements in each step. It's a skill that's worth it."

"A must for all network engineers who want to learn python!!! I had very "very" basic programming skills, and couldn't just get the bridge between network and programming (mainly Python - since that's where the hype is now), this course was amazing, I have never been glued to a training course since I can remember. The couple of things I loved the most about this course: 1- David's clear voice. 2- Real world application, not only will David interduce different real-world practical modules that you can import and use, but he shows you how to apply them on ios devices."

"Excellent course on Network Programming using Python with lot's of practical network configuration examples. High quality content."

Who this course is for:

  • Network Engineers
  • Network Architects
  • If you are interested in network automation
  • If you are interested in network programmability
  • Anyone wanting to learn how to apply Python programming to network automation

Hank’s two passions are technology and theatre. Bringing them together drives him towards a borderline obsession on creating entertaining presentations, labs and demonstrations that breakdown complex technology topics for audiences. After spending several years working on and behind the scenes on stage productions, what started as a hobby turned to a profession when Hank entered the IT industry with a focus on web and database development and engineering. 

Drifting from development into infrastructure engineering brought him to Cisco as a Systems Engineer, focusing on Data Center and Cloud Architecture for large enterprise customers. 

And after six years as an SE, Hank took up the mantle of a Developer Evangelist with DevNet where he can focuses full time on reminding everyone that technology can and should be fun to work with. 

Hank holds a Master Degree in Information Systems as well as several certifications including CCIE R/S 38336 from Cisco.
