Scenario As most IT professionals I usually configure network devices in a lab environment before the actual installation at customer site. I try to limit the installation as much as possible to a simple box moving process, spending most of the change window in a previously defined validation process. In this particular case I deal with a data center core network that includes 8 Nexus 9k switches configured in 4 VPC pairs and a bunch of links between them.

This story starts with a phone call at night. If you worked in IT long enough you know what it means. Customer’s HQ network is down and since the day before I’ve replaced a pair of data center switches in a remote site I’m somehow involved based on the well-known principle last one who made changes is responsible. I state that all the facts took place with my telephone support, without any remote access to the machines.

At Cisco Live Europe in Barcelona I had a chance to see Cisco Candid (Network Assurance Engine) in action.

A couple of days ago Cisco released a Security Advisory. No big deal so far, level was informational so I didn’t read it right away. Title is impressive: Cisco Best Practices to Harden Devices Against Cyber Attacks Targeting Network Infrastructure so i read it during a lunch break just to be aware of the contents. Management sessions to network devices provide the ability to view and collect information about a device and its operations.
Automation and programmability is not a new topic for me. Having studied Information Technology in High School I’ve always coded somehow, never making it my primary focus but always using it as a tool to make my life easier. I remember a script I did in Pascal to create a menu to load custom maps for Doom II instead of using the CLI. It would be great to find it again but it’s very unlikely because I trashed so many PCs and hard drives since, well, at least I hadn’t bitcoins stored there!
For a Network Engineer living and working on the field has some challenges that are not common in office environments. I have a set of tools, hardware and software, that I bought or built over the years that allow me to accomplish my job in more effective way. I used to carry a small Access Point to provide connectivity inside a datacenter or campus when the rack is located in odd places (you know what I mean).
