Let's talk About Networks, by Jerome Tissieres
Cisco Live US 2022 will be June 12-16 in Las Vegas. After two years of virtual conferences and being vaccinated three times against Covid-19, I’m more than motivated to go in person! However, for those who are still hesitating, there is also an online version, over two days, probably in a similar format to 2021.
I just passed the Cisco DevNet DCAUTO (300-635) exam (Yay!). This is my 3rd Cisco exam on network automation after NPDESI in 2018 (replaced now by the DevNet program), and DevNet CORE (DEVCOR) in 2020. But this time, I documented everything I read, so I could report it here and build a Cisco DCAUTO exam study resources. By doing this, I hope to help anyone who wants to study for this certification. And, as I have already passed the DevNet CORE exam, I am now Cisco certified DevNet Professional.

Have you ever wanted to compare the operational state of a bunch of network devices between two specific times? Not only if the interfaces are up or down, but the number and status of BGP peers, the number of prefixes received, the number of entries into a MAC-address table, etc?
This is something quite laborious to do with classical NMS or Do-It-Yourself scripts. And this is where pyATS can become a real asset.
Here are my first steps with pyATS: Network Test & Automation Solution.
Like some other posts, I didn’t think I would write this one because it seemed obvious. But, after talking to a lot of engineers and customers, I realized that not everyone knows this trick. So here it is.
The question is this: how to simulate a real host in a physical network environment when you don’t have computer at your disposal? Well, let’s take an example.
Here is another post of the series on network troubleshooting and tools under Linux.
In this post, I will talk about tcpdump.
In January 1996, I entered for the first time in the configuration of a Cisco 2501 router. This was the beginning of my career as a network engineer. That was just 25 years ago!
Here’s a quick look back and a few tips for junior engineers who are at the beginning of their careers.
As we approach the end of the year, we can finally say goodbye to 2020. Goodbye 2020… and never come back!
But, it is also time to look back at 2020 and try to see what the year 2021 promises us.
I have the honor of having my blog selected as a finalist in the Most Educational category of the 2020 IT Blog Awards, hosted by Cisco.
Many network engineers, myself included, sometimes feel like they don’t belong and don’t deserve to be here. Here are a few tips to combat the impostor syndrome.
On 23 October 2020, I took and passed the Cisco Certified DevNet Professional Core exam (350-901 DEVCOR) on my first attempt. I explain here the resources I used to study and pass this exam.
One of the positive aspects of this difficult period, if I may say so, is the possibility of taking a Pearson Vue test online, called OnVue. Last Friday, October 23rd, I took a Cisco exam from home and I think it’s interesting to share with you the details of this experience. With OnVue – Get certified from your home!
