Hi and sorry for my late reply. I went sick...
I have configured it like you suggested. As soon as I assign VLAN 10 on my switch the PC does lose the connection, no IP address via FDHCP and not even maual IP is working. Not sure if my switch config is wrong. My Intel network card does NOT offer (under device manager) to set a VLAN ID, so I have to test it with my switch.
On switch port 1 I have my RUT attached and on port 9 my PC.
Thanks
