Mac-address NOAGED with DOT1X PORT-MODE MAC-BASED.

[FabianoCh]

We are installing voip phones. The computers are then connected to the phones. The switch ports are configured with dot1x port-mode mac-based.

The mac-address status shows “NOAGED”.  There was no problem before the phones when moving a computer from one switch port to another port.

Now the phone keeps the switch port always UP.  So computer’s mac-address is not cleared from that port.  When the computer is connected to

another switch port it does not authenticate since its mac-address is NOAGED in the port that it was previously.  How to deal with it ?

Thanks to any help.
