Introduction to Spanning-Tree

Hello Patrick

Indeed, 802.3 Ethernet is a somewhat confusing concept when you know that both 802.3 and Ethernet II can operate seamlessly over the same infrastructure. I don’t have something specific to suggest for training material, but you can take a look at this post for some more info:

I will also create a NetworkLessons Note on this topic soon with some additional links, so you can also look out for that.

I hope this has been helpful!
