This is an advanced vendor specific feature. The switch will need to be
running some form of DHCP snooping, or layer 3 header inspection.

I know Trapeze wireless controllers support this (where the IP address
of the client is inserted into the Framed-IP-Address attribute of
accounting packets), but I have no idea about Cisco kit.
