The importance of designing things the right way the first time - and the problems that pop up if you don't.
The things they don't teach you in school, but are necessary for the job - and the lessons I've learned.
You can never stop learning - A bit on certification studies and random new technologies.
A little about the magic that happens in the background - and sometimes saves the day.
We have some new F5 load balancers in our environment, which means I need a method of grabbing regular configuration backups. There are a number of methods out there, but I’ve opted to use SolarWind’s CatTools software since we already own it. The config I used is based on this blog post. It’s a great write-up on how to back
I have always said that I’m not sure I could write code for a living, but I do really enjoy writing scripts that make my life easier. Today’s post is a great example of that. The ease of use offered by the Juniper SRX firewalls and JunOS is something that I wish I had in all of my networking infrastructure.
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
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
You can’t always get what you want. As an engineer though, it’s your job to determine what’s best for the company and recommend it to management. What happens if your suggestion gets turned down? Well certainly your proposal must have been mis-understood, right? Maybe the decision-makers don’t truly understand the risk involved in not following your recommendation, whether that be financial, security,
Last week I came across a thread on Reddit that asked the question: “What is your company’s policy on maintenance windows?”. This got me thinking about how maintenance windows have been handled at the various companies I’ve worked at, and how those schedules/restrictions impact project timelines, network design, etc. Many of the places that I have worked at in the
Today we’re going to take a look at how to configure an etherchannel between two Cisco Switches. What is an etherchannel? It’s a way of taking multiple independent links and bundling them together, so that they appear as one logical connection between two devices. Etherchannels are commonly used between two switches, or between a switch and a host – which
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.
Maybe 2018 isn’t off to quite the best start. Recent processor vulnerabilities have people scrambling to patch and update systems. Stuff like this ends up being a fairly large sink of time for any systems/network administrator. The worst part is that we have practically no control of when this stuff happens or how much time it’s going to take to
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
