I am not aware of any real table, but ClearPass will support whatever the device/vendor supports. It is not a matter of ClearPass supporting or favoring one vendor over another. If the vendor can do XYZ ClearPass can work with it. If the vendor supports ABC; then ClearPass can work with that vendor.
I know now the answer you were looking for, but because CPPM is a multi-vendor authenticator, we truly support whatever the vendor publically promotes (ie. RADIUS dictionaries).
If anyone knows of such a table, please share with Carlos.
