We keep running into issues with trying to image devices using a usb-e1000 NIC. It will get the OS on there, but then once that happens the "pause input" counter on the switch begins to increment and the imaging job fails out. This is when using a cisco 3850.
If we try it on a 2960, the pxe boot process just never starts and the pause input counter just increments until it errors out.
The USB nic is a Plugable branded model usb3-E1000
If you put a dumb switch in between the two devices, the pause input counter doesn't increment at all.
Anyone run into this at all? Is it a driver issue or maybe an ios issue?
