Troubleshooting Webinar this Friday
I’m teaching my troubleshooting webinar this Friday. I’ve revamped the slides entirely, so this will likely be a big change for anyone who’s attended previous versions of this. Three hours, 109 slides, and interaction through the chat window … all to develop some really good skills in how to troubleshoot. For those who are curious, I was taught formal troubleshooting skills in my early life in electronics, learning my lessons on ILS, RADAR, and radio systems of various kinds. This webinar is my adaptation of those skills for network engineers.
What’s your Digital Dilemma?
There are many ways to describe the need for IT organizations to do things better. There are multiple opportunities to get it wrong. Certainly, compromising today in the name of tomorrow is what many IT leaders now call the digital dilemma. Derek Britton of Micro Focus offers the vendor perspective.Back-to-Office Canceled: The New Phase of IT Spending

Stateful Switchover (SSO) 101
Stateful Switchover (SSO) is another seemingly awesome technology that can help you implement high availability when facing a broken non-redundant network design. Here’s how it’s supposed to work:
- A network device runs two copies of the control plane (primary and backup);
- Primary control plane continuously synchronizes its state with the backup control plane;
- When the primary control plane crashes, the backup control plane already has all the required state and is ready to take over in moments.
Delighted? You might be disappointed once you start digging into the details.

For people that want to pursue a career in network design, it can be tough getting the experience needed for such a role. How do you get design experience if your current role does not involve design? There are still many things you can do and I will give you tips on gaining that experience.
Network fundamentals – I always bring this up because it’s easy to overlook the need for network fundamentals. Being an Architect you still need to have technical chops and hopefully some operational experience as well. How can you design for something you are not familiar with? You can’t! You need to know OSPF, ISIS, BGP, etc. to understand when you should use each protocol. Spend a lot of time building these fundamentals before you move into design. How do you do that? Ivan Pepelnjak has training in this area. There is also the Computer Networking Problems and Solutions book by Russ White and Ethan Banks.
Books – There are several excellent books on network design. Some of them are geared towards network design certifications but they are great reads even if you are not pursuing any certification. One of my favourite books is The Art Continue reading
Configuring NSX-T Firewall with a CI/CD Pipeline
Initial implementation of Noël Boulene’s automated provisioning of NSX-T distributed firewall rules changed NSX-T firewall configuration based on Terraform configuration files. To make the deployment fully automated he went a step further and added a full-blown CI/CD pipeline using GitHub Actions and Terraform Cloud.
Not everyone is as lucky as Noël – developers in his organization already use GitHub and Terraform Cloud, making his choices totally frictionless.
