Where is all the Automation?

Matt Schmitz/ July 24, 2018

The future is APIs! SD-EVERYTHING! Automation! Orchestration! Artificial Intelligence and Machine Learning! Sound familiar? It’s all part of the messaging going around in just about everything IT-related. With as much as you keep hearing about it, you might think that it’s all anyone is doing anymore. Yet it still just seems like not a whole lot of people are really

Tips for Working with Vendor Support

Matt Schmitz/ May 9, 2018

This post has been on my mind for a while now. I’ve worked as a network admin for long enough, and opened more technical support cases with vendors than I want to think about. Over the years I’ve developed my own process for how I handle those support cases in an effort to get a quick and efficient resolution. Some

Thoughts on Cisco’s 2018 Annual CyberSecurity Report

Matt Schmitz/ February 21, 2018

When I started in networking, I never would have thought that security would be such an important part of my job. However, it has become something that I’m involved with almost every day – tasks like applying security configurations, participating in audits, or spending a day chasing down the latest vulnerabilities. It’s already become second nature to watch for what’s

Autonegotiation issues on Nexus QSFP Ports

Matt Schmitz/ February 20, 2018

Over the past two years we have made a ton of progress shifting datacenter infrastructure from 1G to 10G+. A majority of this has been through a vendor migration back to Cisco for switching – and specifically using the Nexus 9372 line. These boxes come with 48 ports of 1G/10G SFP+ and another 6 QSFP ports that hit 40G. Late

Matt Schmitz/ January 30, 2018

Today we’re going to take a look at how to configure an etherchannel between two Cisco Switches. What is an etherchannel?

Matt Schmitz/ January 19, 2018

I received an email late yesterday afternoon – to my surprise I was invited to join the Cisco Champions program for 2018! I applied back in November, but I never would have thought I would actually get selected. I’m very excited to join the wonderful group of existing Cisco Champions, a few of which who I’ve bugged on Twitter already.

One Year Later

Matt Schmitz/ January 2, 2018

2017 is over! Now we’re on to whatever 2018 may bring. The past year has been very interesting for me. For one thing, it was the first full year of this blog which started in December of 2016. While I didn’t quite accomplish everything here that I had hoped for, I still managed to do a lot more than I

How to Improve: Stop Doing, Start Understanding

Matt Schmitz/ November 28, 2017

There is a key to being successful at just about any IT job: Stop just doing work, and start understanding what you’re doing. Might seem like an odd thing to say right? But this is something that I have seen confuse engineers at earlier points in their careers. In a lot of jobs, the initial training you receive is fairly

What’s Going Out of Your Network?

Matt Schmitz/ November 21, 2017

Over this past weekend I purchased a few upgrades to my home network/lab. One of which was upgrading my older Ubiquiti 802.11n wireless access point to the newer 802.11ac model they have out. The other purchase was a new external firewall. I had previously been running on a Cisco ASA5505, but the device is older and doesn’t support some of

L2 Basics: Spanning-Tree Protocol

Matt Schmitz/ November 14, 2017

Spanning-tree protocol (STP) is one of those network technologies that is easy to forget about. It exists in the background of almost every network, and for the most part it does it’s job without any issues. However, there is still a huge benefit to understanding what STP does and how it works – because it’s default behaviors might not the
