Post on adding ADCS to be able to provision certificates in a lab to test EAP-TLS and TEAP. This is done on the domain controller and ignoring all the best practices like having an offline root. Don't use this in production! lostintransit.se/2024/10/17/add…

Can't believe we're already 20 years into NETCONF and YANG. If you have a minute, please help Kristian and the IAB give feedback on the future of network management by filling out the questionnaire. We will all benefit from the future standards that come out of this. Thanks 🙏

Got some feedback that the blog is difficult to read due to its brightness. Which do you prefer, the lighter or darker version?

As I’m building out my ISE lab, it got me thinking. How do you simulate having users and devices on your network? Is there something that emulates an iPhone, Android, printer etc. so you can play around with profiling?

Quick post on adding certificate templates in ADCS for my ISE lab. lostintransit.se/2024/10/22/adc…

13 years ago I was in Brussels taking the CCIE RS lab. Time flies! In a month I’m going back to Brussels, but this time to meet up with some dear friends ❤️

Happy with this run 😊

New blog post out on leveraging GPO in my ISE lab to distribute computer- and user certificates, as well as configure the 802.1X supplicant settings. Happy reading! lostintransit.se/2024/11/07/lev…

Can you be successful in IT with a poor memory? Most likely, you're not that much worse than anyone else, what you're experiencing, is called impostor syndrome. Here's how I responded to a Reddit user with some of my advice on combating it.

If you want to learn more about TACACS+ on ISE, this post is for you! It's a super deep dive on everything you need to know to set it up, to verify, getting nerdy with packet captures, debugs, and live logs. Enjoy! lostintransit.se/2024/11/20/tac…

Anyone dealt with iPhone that's stuck in white screen of death? I've tried hard reset, but didn't work. Also tried via iTunes to do software update, but also didn't help. Probably screen is broken? Is it possible to get the data off the phone?

CML 2.8 is out! Time to upgrade the lab. Some of the new features include smart annotations, support for FMC and FTDv, LDAP group support, and custom MAC addresses. I'm going to see what's new with the Catalyst9000v, should be running 17.15 as opposed to 17.12.

I recently upgraded to CML 2.8 and there's a new refplat that gives access to Catalyst 9000v running IOS-XE 17.15.1. The 9000v emulates the ASIC, which makes it comparable to HW. I'm now running my ISE lab and have a Win 10 WM successfully using EAP-TLS to authenticate.

My friend Orhan Ergun has a nice deal for Black Firday. orhanergun.net/pricing

Where am I?

Why is networking so great? My friend Brad really nailed it. It's about the friends we gained along the way.

My friend Russ needs some feedback.

Snow has arrived! Recharging batteries for next week 😊

Leg day!

Have you heard about #mDNS? It's one of those protocols that go under the radar, but that can really wreak havoc on your network if you don't manage it. While mainly used for consumer stuff, expect to see it in your network. It uses link local multicast so gets flooded at L2.
