Introduction If you follow me on Twitter or LinkedIn, you’ve probably seen me talking about a project I’ve been working on called net-textorial. You may be wondering why the funny name? What does it do? In this post, I’m going to go over net-textorial, the tech it’s built on, and why you should use it. […]
Intro Hello again! It’s been a few months since my last post, so I figured it was time to give a little update on what I’ve been up to! After my last attempt at the Cisco DevNet Expert, I was pretty burnt out studying for certification exams. I wanted to do something that reinvigorated my […]
Brief Intro Hello again! For those that are new or need a brief recap of my first Cisco DevNet Expert lab experience, I failed my first attempt and documented my experience in a separate blog post (check it out here!). I won’t go into as much detail as I did in my first experience blog […]
Intro For those that don’t follow me on Twitter (@devnetdan) or my YouTube channel, I began documenting DevNet Expert study journey in the beginning of 2022 (dubbed #RoadtoDevNetExpert). I’ve learned so much along the way and, in this blog post, I’m going to go through everything I experienced along the way, hoping that it will […]
Overview Before we dive into the content, let’s take a step back to appreciate where we are at in building test network environments. It all started with building a physical lab environment, where we had to purchase hardware, physical space, power, cables, and the list goes on… After physical labbing became cumbersome and costly, we […]
Intro Back in October, Cisco DevNet announced the new DevNet Expert certification. As you can imagine, I was pumped to hear the announcement and ready to begin my study preparations. Ever since they announced the Cisco DevNet certifications at Cisco Live US 2019, my goal has been to obtain each DevNet certification level (Associate, Professional, […]
Introduction I first came across sync (synchronous) and async (asynchronous) programming while I was studying for my Cisco DevNet certifications. It was hard to understand at the time why I needed to know about these two programming terms, but after creating some more complex scripts and apps, I started understanding why each concept was important. […]
Introduction Welcome to the fourth and final part to this blog series! In this part, we are going to wrap up pyATS and Genie by looking at some more useful modules within each of these libraries and take a quick look at an open-source web user-interface (UI) for running our pyATS testcases, because who doesn’t […]
Introduction If you’ve been following along in this series, you’ve seen how we can programmatically interact and gather information about our network using pyATS and Genie. That’s great and all, but wouldn’t it be better if we could begin providing true value to ourselves and our team? As mentioned in Part 2, pyATS is essentially […]
Introduction It’s been awhile since my last post, but I finally found some time to sit down and continue writing this series. Since my last post, I have been spending a lot of time reading through the pyATS docs and the experimenting with its modules. In this post, we will be going over the basics […]
