Building a VMware-Formatted Cumulus VX Vagrant Box
In this post, I’m going to walk you through the process I used to build a Vagrant box for Cumulus VX that will work with VMware desktop hypervisors (like VMware Fusion or VMware Workstation). Although Cumulus Networks offers several different versions of Cumulus VX to download, they do not (strangely enough) offer a Vagrant box that will work with VMware’s desktop hypervisors.
If you’re not familiar with Cumulus VX, it’s a virtual appliance version of Cumulus Linux. This allows you to test Cumulus Linux without needing compatible network hardware. This is really handy for testing configuration management tools against Cumulus Linux, for testing complex topologies before you implement them in production, or just for getting a feel for how Cumulus Linux works.
Naturally, this sounds like a perfect fit to use with Vagrant, so if you’re interested—as I am/was—in running Cumulus VX with Vagrant using a VMware desktop hypervisor, then the process described below should get you all fixed up.
First, you’ll want to get a hold of the VMware version of Cumulus VX. Navigate over to the Cumulus VX download page (a free registration is required), and download the VMware version. This will download an OVA file. Don’t Continue reading

Why automation is the key to the future of cyber security
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
In 2015 there were 781 publicized cyber security breaches which resulted in more than 169 million personal records being exposed – a number that’s steadily on the rise year over year. And with notable names like BlueCross, Harvard and Target being tossed into the mix, it’s obvious that no company is safe. Yet, only 38% of organizations across the globe can confidently say they are prepared to handle a sophisticated cyber-attack.
The numbers don’t lie. Cyber criminals are becoming savvier and their attacks are increasing faster than companies can keep up. Furthermore, it’s becoming increasingly evident that traditional methods, like anti-malware software, are no longer sufficient to keep sensitive data safe. To address this glaring need, many forward-thinking IT executives are fortifying their cyber security strategy using automation as a tool for greater defense.

The importance of situational awareness for network engineers
In another life, not too long ago, I spent a number of years in civilian and military law enforcement. When going through just about any kind of tactical training, one of the recurring themes they hammer into you is “situational awareness or SA.”
Wikipedia defines SA as:
Situational awareness or situation awareness (SA) is the perception of environmental elements with respect to time or space, the comprehension of their meaning, and the projection of their status after some variable has changed, such as time, or some other variable, such as a predetermined event. It is also a field of study concerned with understanding of the environment critical to decision-makers in complex, dynamic areas from aviation, air traffic control, ship navigation, power plant operations, military command and control, and emergency services such as fire fighting and policing; to more ordinary but nevertheless complex tasks such as driving an automobile or riding a bicycle.
Defining the need for SA in network engineering
It’s interesting to notice that critical infrastructure such as power plants and air traffic control are listed as disciplines that train in SA, however, I’ve never seen it taught in Continue reading
