Cisco Live 2022

May 13, 2022 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 am really looking forward to it and being able to talk and interact with my former colleagues, friends, and peers again. This is probably the best part about attending a conference in person: meeting…

Cisco DCAUTO exam study resources

January 31, 2022April 25, 2022 Jerome Tissieres

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.

First steps with pyATS

November 29, 2021 Jerome Tissieres

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.

How to simulate a host in a real network?

October 10, 2021 Jerome Tissieres

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.

Goodbye 2020… and never come back!

December 21, 2020December 21, 2020 Jerome Tissieres

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.

OnVue – Get certified from your home

October 28, 2020October 28, 2020 Jerome Tissieres

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!
