Excerpt: I’m pleased to announce a new feature on the site. I’m going to start publishing some articles on more fundamental concepts in networking in the form of video walk throughs / labs. I wanted to free up the main blog feed for some more advanced topics, and a lot more of an overall network design discussion, as well as the occasional fun stuff. Several people have approached me in the past about making something like this that would help beginners learn the fundamentals, and at the time I wasn’t able to, but I feel like I’m able to do them now. I…

Keeping It Classless Labs – Static Routing
August 30, 2011 by Leave a Comment
This is the first in what I hope to be a useful series on configuration/walk through videos aimed at educating up-and-coming networking professionals on some of the more fundamental concepts. Today we’ll be looking at static routing and how to configure it in a small Cisco network. Below are the lab files (GNS3) and the videos themselves. Download the Lab Outline Download the GNS3 Lab used in this video Since it’s a new Youtube channel, I’m limited to 15 minutes per clip, and therefore had to break it into two parts. First, part one: http://www.youtube.com/watch?v=_68EpWrSXWY And part two: http://www.youtube.com/watch?v=JDPKC0RslvQ

Excerpt: The television and video game industry are just absolutely RIDDLED with terrible attempts at referencing technology. Typically, these scenes will try to delve into some sort of computer-like concept, often related to computer networking, to try to improve the modernity of the content. Before you say anything, I did pull a bit of inspiration from this Cracked article, but there are a few I’ve encountered on my own. I hope you enjoy! NCIS – “I’m getting hacked!” My main reason for going into this one is that the aforementioned Cracked article mentioned that they’re not going to argue the technical details because they…

Excerpt: Over the past few years, I’ve made some observations about the people I’ve worked and communicated with. Some of these people were colleagues, others acquaintances, and still others were simply bloggers that I look up to. I’m talking specifically of those people that are in my field of Network Engineering, and they all share a few traits in common. I’ve deemed a few of these traits to be important things to remember when trying to make yourself a better network engineer, and a better IT professional in general. Never Stop Learning Many network engineers get this right – at first. If you’re…
Monitoring an entire VLAN on a Layer 3 Switch

Excerpt: A recent and relatively quiet IOS release allows the Catalyst 2960 platform to perform limited Layer 3 Switching (See this thread and this blog post). There are limitations – for instance, it cannot run any sort of routing protocol, so routing must be done statically. Up to 16 static routes can be entered, and routing is limited to SVI’s (maximum of 8), as the platform is not able to route to or from a physical interface, like you’re able to do with most layer 3 switches. I have a few Catalyst 3550′s in my lab at home, I wanted to get…
