Here’s another idea from the Building Network Automation Solutions online course: Ruben Tripiana decided to implement a latency measurement tool. His playbook takes a list of managed devices from Ansible inventory, generates a set of unique device pairs, measures latency between them, and produces a summary report (see also his description of the project).

Got this feedback on my Ansible for Networking Engineers webinar:

This webinar is very comprehensive compared to any other Ansible webinars available out there. Ivan does great job of mapping and using real life example which is directly related to daily tasks.

The Ansible online course is even better: it includes support, additional hands-on exercises, sample playbooks, case studies, and lab instructions.

However, Ansible is just a tool that shouldn’t be missing from your toolbox. If you need a bigger picture, consider the Building Network Automation Solutions online course (and register ASAP to save $700 with the Enthusiast ticket).

I know that everyone learns in a slightly different way. Let me share the approach that usually works well for me when a tough topic I’m trying to master includes a practical (hands-on) component: running controlled experiments.

Sounds arcane and purely academic? How about a simple example?

A week ago I talked about this same concept in the Building Network Automation Solutions online course. The video is already online and you get immediate access to it (and the rest of the course) when you register for the next live session.

We’re slowly wrapping up the autumn 2017 Building Network Automation Solutions online course, so it’s time to schedule the next one. It will start on February 13th and you can already register (and save $700 over regular price as long as there are Enthusiast tickets left).

Do note that you get access to all course content (including the recordings of autumn 2017 sessions) the moment you register for the course. You can also start building your lab and working on hands-on exercises way before the course starts.

Third vendor in this year’s series of data center switching updates: Cisco.

As expected, Cisco launched a number of new switches in 2017, and EOL’d older models … for pretty varying value of old. For example, most of the original Nexus 9300 models are gone.

One of the undergraduate students attending my Ansible for Networking Engineers online course got to the point where he wanted to start hands-on work and sent me a list of questions:

Do I have to buy a VIRL license to use your Ansible course materials? Or is VIRL in any Github repository? Is there a way to use your files in a free Tool like GNS3?

Let’s go through them one by one:

One of the sample Ansible playbooks I published to help the attendees of my Building Network Automation Solutions course get started collects LLDP neighbor information on all managed devices and converts that information into a network diagram.

Here’s the graph I got from it when I ran it on my 6-node OSPF network (the Inter-AS VIRL topology from this repository). Please note I spent zero time tweaking the graph description (it shows).

David Gee (whom I finally met in person during recent ipSpace.net Summit) published a fantastic series of articles on what someone bringing together networking, development and automation should know and do.

If you’re a long-time reader of my blog you probably know that I believe in learning the fundamentals before trying to do anything else (like Google-and-Paste spaghetti wall approach), so you could imagine my delight when I got this feedback from an engineer watching (free) Network Programmability 101 webinar:

I was expecting a technical webinar, so I was a little bit disappointed at first with a “meta” webinar, but as I got through I was more than happy; learning such a meta sphere or getting to know other mindsets is very useful for me. The webinar pushed me to think outside of my little world and to open my mind.

That's exactly what I'm trying to achieve with the high-level webinars. So glad to hear it worked ;))

You might have noticed the “upcoming webinars” blog widget is gone and I’ll write a blog post every two weeks or so to keep you updated on upcoming webinars and other events.

Here’s what’s coming in September and October 2017:

• Does Docker (and containers) make sense with Cumulus Networks on September 21st in Zurich;
• Docker workshop on September 21st in Zurich;
• DevOps and Security for Enterprise Environments on September 28th;
• Second part of Network Visibility with Flow Data webinar on October 5th;
• Network automation workshop in Rome on October 18th.
