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.
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.
During the past three years, I have spent a good portion of my time testing, planning, designing, and then migrating our DC network from Cisco FabricPath and Classic Ethernet environments to VXLAN BGP/EVPN. And simultaneously, from a hierarchical classic two-tier architecture to a more modern Clos 400Gb-based topology.
The migration is not yet 100% completed, but it is well underway. And I have gained significant experience on the subject, so I think it’s time to share my knowledge and experiments with our community.
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.
I have the honor of having my blog selected as a finalist in the 2021 IT Blog Awards, hosted by Cisco.
It is a privilege and a great joy for me to have my blog selected for the fourth consecutive year! Congratulations also to all of the other finalists, who all produce great and valuable content!

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.
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.
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!
On a previous post, I made an introduction about NVMe, NVMe-oF and RDMA for network engineers. In this post, I’m going to talk about RDMA over Converged Ethernet (RoCE) and more specifically how to implement and configure the QoS part of RoCEv2 on the Cisco Nexus 9300 series.
If you have more than three Cisco Nexus switches in nx-os mode, and you are not using Cisco DCNM or any other similar tool, you probably already have encountered this question: How to automate file uploads to your Cisco Nexus switches?
Here is a turnkey Python script using Netmiko’s SCP function to do this.
