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.

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.

Initial Cisco C9115AX Testing

With a brand new Cisco Catalyst 9115AX access point in my hands, it’s time to start testing. Before we begin testing Wi-Fi 6, I had acquire a compatible client. So after an Amazon order and waiting two days, I am a proud owner of an unlocked Samsung S10. To be fair, testing Wi-Fi 6 with […]

Python Day 4: Dictionaries

Dictionaries Indexes for dictionaries are called keys. Keys are associated with a value called a key-value pair. A dictionary is unordered. Compared to a List, there is no index starting at 0. Dictionaries are typed with braces [python]{}[/python]. To assign a dictionary to the client1 variable: [python]client1 = {‘rssi’: -52, ‘channel’: 36, ‘noise’: -96, ‘tx […]

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 […]

DevNet Associate Challenge

For over a year I’ve been making excuses when it comes to learning how to code. In the beginning I had chosen Python as my coding language of choice. Now we have the DevNet Associate certification! With the announcement of the new Cisco DevNet certifications, I’ve kicked around the idea of really taking the plunge […]
