The Future of Network Engineering in the AI/ML era
Views: 1
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:

This is a very short post, as a complement to my previous post about PyATS, Genie, and RobotFramework.
How can we see the debug logs of RobotFramework?
Cisco DCAUTO exam study resources
Views: 0
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

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.

Automate file uploads to your Cisco Nexus switches

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.

Shutdown thousands access ports with Python and Netmiko
Views: 0
When people ask me “what a network engineer should do to start in network automation?”, my first answer is: start with small things. Try to automate basic and repetitive tasks you do every day. Go after the low-hanging fruits first. Then, step by step, you can do more and more complex things. This is how I learn the best.
In the same vein, I want to share with you my recent experience of automating a very basic and repetitive task: shutdown thousands of unused network access ports.

Cisco Embedded Event Manager (EEM)
Views: 1
The Cisco Embedded Event Manager or Cisco EEM is a software component of Cisco IOS, IOS-XR, and NX-OS that provides real-time network event detection and onboard automation.
EEM allows you to automate tasks, perform minor enhancements and create workarounds and can makes life easier for network operators by tracking and classifying events that take place on a network device and providing actions options for those events.
