Learning Python Boolean values and operators is part of the series — Zero to Network Automation. In this post, we’ll explore Python Boolean values and operators — the building blocks of decision-making in scripts and network automation. In network automation, we constantly make decisions — “Is the interface up?”, “Did the script succeed?”, “Is the … Continue reading What are Python Boolean Values and Operators→| Rowell Dionicio
Everything comes down to evaluating expressions. That means our code isn't going to be ran from the start to the end of the code sequentially. Our code will use flow control to decide what to do next. And with networking, we're likely to decide what to do next after looping through a set of data to meet a condition. I feel it is important to know about flow control to make decisions and to repeat tasks. Things we will do when dealing with networks. Flow control will start with some sort of co...| Rowell Dionicio
This is the first real step in my Zero to Network Automation journey — learning Python from the ground up. In this post, I cover the absolute basics: the data types, variables, and functions that f…| Rowell Dionicio
I’ve avoided Python and network automation for the past 5 years. I felt it wasn’t required to get the job done. But here’s the shift: the projects I’m working on now could b…| Rowell Dionicio
For the past 5+ years, I’ve avoided Python and network automation. I told myself I could get by without it—after all, I’ve designed and troubleshot Wi-Fi networks, deployed switches, and solved cli…| Rowell Dionicio
Should we be thinking about doing networking differently? We’ve been planning and deploying the same way for many years. But Nile is executing on a bold vision that challenges our long-held beliefs. Resetting Legacy Networking We’ve grown accustomed to managing complex networks with protocols like Spanning Tree and dealing with traditional NAC solutions. But these […]| Rowell Dionicio
Remember when Ubiquiti’s UniFi was the scrappy underdog of networking—beloved by small businesses for its affordability but largely ignored by enterprise IT? Well, those days might be behind us. Ubiquiti is making some serious moves in 2025, and frankly, it’s about time. They’re not just tweaking their existing lineup; they’re completely changing what UniFi can […]| Rowell Dionicio
Fortinet’s new concept, the FortiAP 231KD access point, caught my attention at Mobility Field Day 13—not for its Wi-Fi 7 capabilities, but for something far more unusual: a built-in LCD screen. Yes, that’s right. An access point with a display. This makes me wonder about technology convergence: Just because we can merge different technologies, should […]| Rowell Dionicio
Large campus networks are facing challenges supporting massive Layer 2 domains while ensuring seamless client mobility across campuses. It comes with significant hurdles. For years, IT teams have struggled with issues like ARP flooding, excessive hardware costs, and outdated proprietary solutions. But do we still have to live through “the broadcast storms of the 1980s,” […]| Rowell Dionicio
Private 5G continues to evolve, and Celona’s latest move is the right step: eliminating the need for on-premises edge appliances through what they call Edgeless Private 5G. It’s an architectural shift that simplifies how enterprise cellular networks are deployed and managed, especially with Neutral Host. Towards the cloud. But here’s my take: Innovation alone isn’t […]| Rowell Dionicio
Cellular coverage inside enterprise buildings still kind of sucks. But that’s what Celona is positioned to solve. We’ve been solving the problem with Wi-Fi and DAS for too long, and it shows. Mostly due to poor deployments. Whether you’re walking through a hospital corridor or sitting in the basement level of an office building, there’s […]| Rowell Dionicio
