And remember, auto-negotiation is NOT a cable health check. It could just BARELY support the momentary 100Mbps or 1GbE signaling.https://t.co/l2VxmpAaBs https://t.co/rZZQ2s2ToD

Ha, yes! Have argued with people about this before, many times.
Them: “But it negotiated at 1Gb/s.”
Me: “Sure, but that’s just what speed the ports can run at. Let’s try manually setting it to 100Mb/s and seeing if the connection works correctly.”
Them: “But it negotiated at 1Gb/s.”
Then we try it and sure enough, works fine at the slower speed. Cable can’t do 1Gb/s, but the ports can. I wish more IT people had a better model for what’s actually happening in the real world. Never mind the users, they will never know anything. But IT people should and they don’t all too often.
