so anyway did u know there are ethernet sublayers other than the MAC & LLC? :)

The people who designed that were geniuses. You know how badly a network can be configured and yet data will still flow. Well you do. But something that I had to discover.

I did, but didn't realize there were multiple sublayers within PHY.

yeah, those are ethernet sublayers that sit at the PHY level

And if you have hardware that talks MII, it’s possible to manage an unmanaged switch (chipset dependant) and enable vlans, spanning, etc!

I've learnt from that diagram that cables are not layer 1 which I shall now employ to make myself sound learned and greybeard. Thank you.

Oh wow. I’m now learning that some consider the physical cables as Layer 0…

Yeah - remember the 7 layer OSI model from my 1985 CompSci masters.. taught by some of the people who built it

The artisans who made networking work, and the ivory tower wizards who begat the seven-layer cake, had sort of heard vague rumours of each other from time to time.
