I'm running Aastra IP-phones with 802.1X on Cisco 2960-switches 15.0(2)SE2 and 12.2(55)SE5.
Both phones and clients are authenticated and works fine. My problem is that the phone does not drop the clients mac address when the client is disconnected. It is not possible to disconnect the client from the phone and connect the client either after another phone or directly to a switch port. It does not help to reload the PC or release IP address or even disconnect the client over night. The phone still advertises the client mac address along with it's own. The only thing that works is to disconnect the client and reload the phone.
Authentication mac-move permit is configured on the client but has no effect.
There is no problem to move clients that is directly connected to a switch port. So it seems like the phone don't want to release the client mac address.
Phones are not configured by me. Is there anyone else who has the same problem?
