Hi, I’m Rowell

This is my personal blog where I discuss and share technical topics from network engineering, wireless, and network automation.

Join Me On the Network Junkies Discord

I’m building a community, Network Junkies, where anyone from beginners to experienced network engineers can get together to learn, speak, and ask any question (there are no stupid questions) in a safe space. Get to know others in the community and improve your skills. Join me on Discord today!

What I’m Working On

I did a live stream 7 days straight to discuss network engineering during this weird time. I’m doing this to challenge to myself in public speaking & to encourage myself to do more learning and labbing. I will continue to do a live stream regularly.

Recently passed  the Cisco DevNet Associate and now I’m helping others learn so they can work towards automating and managing network devices more efficiently and obtain the DevNet Associate certification.

It's time to parse XML using Python. I've learned how to use the requests module to form a GET request to a network device. Taking the response, I convert it into a string which will be fed to xml minidom to create an XML variable containing the content I want. From that content, I'll parse out specific information using XML elements and attributes. I found this useful for studying the Cisco DevNet Associate.

If you start to think the problem is ‘out there,’ stop yourself. That thought is the problem.

Playing with technology. Borrowing moments in a photograph.

I focus on Wi-Fi. Designing, configuring and testing connectivity for enterprise companies. When I’m not doing Wi-Fi I’m traveling, eating, and wandering.

XML Basics for DevNet

Understanding the basic concepts of the XML format and the content it contains will be important when dealing with APIs and writing scripts. I continue my series in studying for the Cisco DevNet Associate certification. XML stands for Extensible Markup Language and is a way to describe sets of data. Its purpose is to be […]

Intro to JSON for DevNet

In continuation with the DevNet Associate Challenge, I look at the JSON structured data format. It’s heavily used with Cisco documentation and training. If you’re studying for the Cisco DevNet Associate certification, it will be critical to understand JSON and how it will be used with scripting and APIs. JSON stands for JavaScript Object Notation. […]

DeMISTifying Wi-Fi Issues

Mist Systems first delivered a new way of looking at Wi-Fi at MFD2. I was impressed with their product and I continue to be impressed with the progress they’ve made since their last time at MFD. What Mist Systems brings to the table is a way of managing Wi-Fi the way it should be in […]

Attendee Guide To Cisco Live 2019

Cisco Live is making its way back to the West Coast which is easier for me to travel and attend. There’s no excuse to miss it. I’ve attended Cisco Live since 2016 and have had a great experience each time. It gets better every single year for me. And last year I probably attended more […]

Parsing XML with Python Minidom

A core skill for a DevNet associate is being knowledgeable of how to parse XML into a Python structure. Watch this video on YouTube Data can be retrieved from devices using different data structures such as XML, YAML, or JSON. In this lab, I’ll look at parsing XML into a useable structure within Python. First […]
