About this blog

“It would be nice to write this in a blog, to help the next person who has the same problem!”

That’s what I say, every time I meet a new challenge or problem and cannot find the corresponding documentation. Or, when I found undocumented behavior on a network device or protocol.

As a network engineer since 1996, I have spoken this phrase millions of times. So here it is now: I created this blog.

Here, I will talk mostly about Cisco, Meraki and Huawei network systems, the related software for network planning, design, operations, troubleshooting and automation. And about my learning experiences in networking, software scripting and cloud.

 

 

About me

My name is Jerome Tissieres, I live in Switzerland and I am network engineer since 1996.

Jerome Tissieres

I held many different network engineer positions since 1996. You can find my complete professional experience on my LinkedIn page.

During that time, I also kept an important place for learning and self-study. I love learning, study and practice new technologies, and I also like to share this knowledge with other people. Working as a network engineer for over 20 years, I have constantly learned: on network technologies, of course, but also on network design, best practices, troubleshooting methods, configurations and fault management, monitoring, scripting, network automation. And I am still learning almost every day. This is why I have a passion for this job: I always learn something new!

And not CCIE?

This is true, I am not CCIE. I passed three times the CCIE R&S written exam (versions 4.0 and 5.0) and I failed four times at the CCIE Routing and Switching lab exam in Brussels. Once at the exam version 4.0 in 2013, and three times at the version 5.0 between 2016 and 2017. After that, I have stopped chasing my CCIE numbers to be able to learn other technologies.

During this great journey, I took two Narbik Kocharians / Micronics’s bootcamp and completed multiple times the practice lab workbooks of INE, iPexpert and Narbik. I also did many practice labs from Cisco expert-level training (formerly Cisco-360). This was a fantastic experience during around five years and I learned a lot!

 

 

Personal Side

On the personal side, I am married to a wonderful wife, I have three beautiful children and my mother tongue is French.
Since 2010, we live in a nice place called “The Magic Valley” or Vallemaggia, in the Italian part of Switzerland. I speak Italian, French and English with my colleagues and customers.

Please note: English is no my mother tongue, this may explain some spelling mistakes on this blog, my apologies in advance.
