For those of you who are new to the site, welcome! I wanted to start with “Why Networking,” and maybe it will help you find your “Why.” My first post dates back to 2013 when I was just a Network Administrator. Before that, I remember reading technical blogs and books at the infancy of my IT journey. There’s so much fantastic content out there.

In my previous role, I had the opportunity to wear many hats, including Network Administrator. Our go-to networking vendor before I moved on was Extreme Networks. When I initially started my position, the campus was a Cabletron customer, then Enterasys, and lastly, Extreme Networks (Believe it or not, there’s more than one way when it comes to Network Vendor selection). Now the transitions did come upon company acquisitions. And after each acquisition, we did our due diligence and reviewed…

I’ve made quite a few changes to my site. The first thing you’ll notice is the name change. I decided it was time to move away from the Apextier domain name. I originally received the domain from a close friend. My original intent with the site was using Apextier to run a side job for web dev work years ago. I eventually stopped building websites. Apextier sounded cool at the time and became a useful place for my technical blog. I decided that something like LifeNetEng was more personal and…

Being a Systems Engineer or really a “Sales” Engineer, I speak with lots of IT folks about products that Extreme Networks sells. Rarely do I have conversations around hardware features such as feeds and speeds or physical components. Every competitive networking vendor mostly has access to the same commodity ASICs. In the networking and infrastructure world software has become King or Queen. Software is the driving factor for change and creating some healthy competition in the Networking…

You can find some of my original Aerohive AP121 blog posts here. Since then Aerohive has been acquired by Extreme Networks. So I ended up activating an AP230 to the Aerohive HiveManager cloud and was also curious if I could resurrect my old AP121. Low and behold, the AP121 was still supported in HiveManager. I was able to get the AP serial number registered to my new account and added to my HiveManager cloud portal.

You’re probably thinking why are we still talking about NAC? In my opinion, NAC is one of the bests ways to apply dynamic assignment of access control and gain visibility to where devices are connected to the network in real-time in an agent-less fashion. By the way, us networking folks hate agents. We don’t want to be in charge of one more application, especially if its deployed on thousands of machines.

I recently attended a CWNA course taught by none other than Devin Akin, wireless guru and co-founder of CWNP. During the course I was reminded about how attenuation can become your best friend when building high density Wi-Fi networks.

I came across a scenario where a user had two data centers in different locations connecting back to the same ISP via BGP. These two data centers would be advertising a unique /24 at each site. However, the user also wanted to advertise the other DC’s /24, but not in an active state for failover. Being that the user was connecting back to the same provider AS, I decided to test using the BGP MED (Multi Exit Discriminator) attribute to determine which /24 would be the preferred route from the…

As a systems engineer for Extreme Networks, I like to get as much hands-on lab gear that I can within a reasonable budget. I have quite a large lab setup at home as you can see.
