I have a wired 802.1x auth setup on cisco gear.  I would like to
record the IP address of machines that connect and are authorized.  Is
this possible?

I currently see NAS-IP-Address and Client-IP-Address as the IP of the
switch.  The Calling-Station-Id is the correct mac address of the
authorized machine.  The machines that are connecting to be authed are
allocated their address using dhcp.
