The InterNetwork is a blog about my experiences consulting as a Network Engineer. With this blog, I will be sharing my understanding of different technology, gotchas and caveats that I will inevitably encounter, and exciting new technology I find. Most of my posts will be Cisco-centric as I do work for a Cisco Gold Partner and deploy their solutions, however working with companies from the smallest small businesses to enterprise corporations I am exposed to many different products from different vendors.

I started this blog after listening to an episode of PacketPushers where they talked about giving back to the IT community as a whole. Writing blogs and being active on message boards is how many problems get solved. I have used both blogs and answers in forums to solve many solutions over the years, so I felt it was time to give back, so The InterNetwork blog was born. I hope that you get something out my experiences and maybe help solve a problem you may have!

In my ongoing effort to randomly write about what I am actively working on, I am currently deploying an SD-Access fabric using Cisco’s DNA Center, now rebranded as Catalyst Center. As part of this project we used the LAN automation process to build the network to all of the access switches. We had about 15 different switches … Continue reading Using DNA Center (Catalyst Center) LAN Automation to make your life easier.

Cisco Cloud-Delivered Firewall Management Center

September 28, 2023 by Trevor Butler, posted in Gotcha's & Cavates, Modern Security

Starting with Firepower 7.2 Cisco announced the ability to manage these firewalls using a Cisco hosted Cloud-Delivered Firewall Management Center (cdFMC). I recently had a project setting up cdFMC for the first time so I figure I would go over what I learned and show how to access cdFMC, how to import policies, and join … Continue reading Cisco Cloud-Delivered Firewall Management Center

Documenting your Network

March 30, 2023 by Trevor Butler, posted in Beyond the Network

Network documentation is arguably both the most important and most over looked tasked a network administrator does. A good network diagram is invaluable for understanding how a network is working, for troubleshooting when its not working, and a great source of information when onboarding new employees to the network team or, more important to me, … Continue reading Documenting your Network
