Dad jokes aside, this post is just a short video about restconf. Restconf, for the unfamiliar, is a protocol for programatically interacting with a network appliance. It allows you to leverage the power of a programming language called Python to configure and monitor fleets of routers and switches with a
Why VLANs? Computer networks are vital for our connected world, enabling communication and data transfer. One important concept within these networks is Virtual Local Area Networks (VLANs). In simple terms, VLANs help organize devices, improve security, boost performance, and make network management easier. Let's dive into VLANs and
Cisco VTP (VLAN Trunking Protocol) is a proprietary protocol used in Cisco networking devices to manage and propagate VLAN (Virtual Local Area Network) configurations across a switched network.

After receiving my CCNA and following up with the JNCIA certification, the next steps in my professional development as a network engineer have been anything but clear.

I’m amazed at how even just a little bit of travel hits the reset button on the creative flow. It is as though the hum-drum of everyday life droning on drowns out the whispers of inspiration. But when you venture out into the unknown, whether it's to
Your mom doesn't work here—clean up after yourself! Descending into the smoggy haze that calls itself home after a reprieve with a clean-sky week abroad, I was reminded of just how much filth we subject each other to in Seoul. The first place I headed after getting
I know a place where you can find solace in the simplicity of cheap coffee and mediocre curry for breakfast. It may not be the epitome of luxury, but sometimes all we need is a familiar setting that offers a sense of comfort. Nestled in a remote corner of the
Enabling SSH on Cisco IOS is a secure way to remotely access and manage your network device. SSH encrypts all traffic, preventing any unauthorized access to your Cisco device. In this post, we will walk you through the steps to enable SSH on a Cisco switch. The process is the
Artificial intelligence (AI) has rapidly advanced in recent years, leading to many concerns about its impact on society, including its potential to replace human creativity in fields such as art, music, and poetry. However, while AI is capable of producing impressive works of art and music, it is not the
Hello and welcome to Cisco IOS! In this tutorial, we'll go over the basics of navigating Cisco IOS and some common commands that you'll need to know. First, let's talk about the command line interface (CLI). The CLI is where you'll enter
