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.

In today's LinkedIn post, I talk about risks as they relate to projects.

You need to understand the impact, probability, and triggers.

1. Find the risk.
2. Analyze it.
3. Develop a risk plan.
4. Mitigate.

In infrastructure projects, business requirements are often overlooked.

What are some of your favorite questions to ask when collecting business requirements? 🤔

Why do we love networking? My friend Brad with one of the best explanations I've seen.

I've been super busy lately, but trying to make some progress on that IBNS 2.0 blog post. Here's a sneak peek.

It all comes down to an event triggering, then based on matching different things in the classes, taking an action.

It will take time to put this together, but it will be unique content.

I found the missing debug!

You can get this data from show logging process smd internal if you have the proper debugs enabled. I'm going to use this in my IBNS 2.0 post to show how you can see the flow of the policy.

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.

I'm all about highlighting people that deserve to be highlighted. Certificates and TLS can be difficult to grasp and no one does a better job at explaining it than my friend Ed Harmoush.

Great deal on his course right now.

Am I a person that will spend hours finding how to do a specific debug for control policies in 802.1X on Catalyst 9000? Yes, yes I am 😅

I'm writing several blog posts on IBNS, policy sets, etc., and I NEED to know how it all works. Then hopefully I can share what I learned with you all ☺️

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 in earlier versions of CML.

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!

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.

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!

Running RADIUS in public cloud or SaaS, what do think? Are you seeing a push for this? What has been your experience of deploying it?
October 25, 2024 at 4:26 AM
Looks like some people are moving here. Let's get some discussions going!

Let's say you run EAP-TLS for WiFi. Your RADIUS is SaaS. You'll likely see UDP fragments. What do you expect happen to your fragments as they traverse the interwebz?
