I connected a DeskPro to an MS120-8FP switch and configured dot1x with Multi-Domain authentication. The DeskPro gets placed into the voice vlan as expected, when connecting a PC it gets assigned the data vlan (both via CoA fromt eh Radius server). So that looks fine.
However, when the PC disconnects and reconnects later, no new authentication happens. The PC immediately gets access again. If adding a different PC, it gets no network connectivity at all. My guess it this is due to the different MAC address.
I suspect (without confirming) this happens with other IP phones as well.
This means each time I connect a different PC to the DeskPro I need to unplug the network cable of it to trigger a new authentication - which is not a viable option.
Anyone knows how to get the MS120 to trigger reauthentication when a PC gets disconnected/reconnected?
