If you're doing 802.1x authentication, then it will be the MAC. The supplicant may not even have an IP address when it communicates with the NAS (the ethernet switch) if it is configured for DHCP.
If you're logging into the CLI of a device configured to authenticate using RADIUS, then I would not necessarily expect there to be a Calling-Station-Id. If there were, I'd expect it to be the IP address, since the communication between the remote client and the network device is all via IP. I can't think of any other reason for an Ethernet switch to make a RADIUS request.
