That is helpful, thank you.
A portion of that article,
The Alignment and FCS errors are detected when the full-duplex port will transmit without listening, and this will sometimes corrupt the messages transmitted by the half-duplex port.
If a hub or unmanaged switch is utilized, then all devices need to be configured for Auto Negotiate.
We have an unmanaged switch in our configuration, I had set all other devices to fixed full/100, to correct a different issue, perhaps I created a new one!
