Docking Stations

I have a startech docking station connected to a Mitel phone and in ISE I can see the MAC address of the Dock when a laptop is plugged in. The authentication for the dock fails, which is fine as it can't find a profile for it and comes up as 'Unknown'.

When a laptop is not plugged in to the dock, there is no activity on the network port.

When a laptop is plugged in it starts flashing. If it's a laptop with the correct dot1x settings and a certificate the laptop authenticate fine but ISE logs the docking station MAC against the PC name. This is problem 1.

Problem 2 - If a laptop that is unauthorised comes along and plugs in, the laptop is rejected but the logs in ISE continue to show the docking station MAC over and over even if the laptop has been unplugged. Almost like it's cached or as if because the phone is keeping the authentication alive on the switchport, it continues to try and re-authenticate the dock even though there is no activity light after the laptop has been unplugged.

Any help with these 2 issues?

 

thanks
