Let's talk About Networks, by Jerome Tissieres
I just completed the Programming for Network Engineers (PRNE) learning path training on Cisco U and would like to share this with you:
For a limited time, you have FREE access to learn Python AND earn 24 Cisco Continuing Education credits to apply toward recertification.
The PRNE Learning Path must be completed before November 22, 2024.
I recently tested the NVIDIA Air Infrastructure Simulation Platform and would like to share my first experiences with you.
Last week, I attended my 11th Cisco Live in person, in the fabulous Las Vegas. This post is my Cisco Live 2024 Wrap-up.
I can already tell you that the next edition of Cisco Live US will be held June 8-12, 2025 in San Diego, California. If my company agrees to send me there, I’m already looking forward to it, because San Diego is a wonderful city.
Once again this year, Cisco Live US 2024 will take place in Las Vegas, Nevada, from June 2 to 6, 2024.
I’m already registered and I’m looking forward to it! This year will be my 11th time attending Cisco’s annual conference in person, in both Europe and the United States.
It seems like yesterday when I saw my first network automation presentation at a conference. I remember it very well; it was in 2015 at the Cisco Network Innovation Summit in Prague. Mr. Tim Szigeti was presenting the first version of the Cisco APIC-EM, the future Cisco Digital Network Architecture (DNA) controller. I talked already about it in a previous article, written in 2018, about my journey toward network programmability and automation.
After its presentation, and for many years afterward, the question was on everyone’s lips:
Cisco Live US 2023 will take place from June 04 to 08 in Las Vegas. I have just registered, and this will be my 10th time attending. However, the question arises: is the Cisco Live conference worth the price?
This is a very short post, as a complement to my previous post about PyATS, Genie, and RobotFramework.
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.
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.
