I went through exactly this problem on my network, I use a Cisco Catalyst 2960 X, which solved it was to configure spanning-tree on all ports, and configure portfast on all but the trunk port (since we use more than one DHCP here). Good Luck!
FOG can clone them, I’m not sure how well it works in practice, though. I don’t think they can be resized automatically, so they’d be captured full size, however.
@wayne-workma Thank you very much for your help, your first question helped me. I never moved the client machine over to the switch, I just ran the FOG Server alone on the switch, once I moved to client over to the switch, the FOG Management was to run and work properly.
