802.1x authentication using DUO MFA

Hi All,

I'm trying to test the usage of DUO integrated with ISE. Is it possible to achieve dot1x authentication which can be utilized in both Windows/MAC supplicants?

Is it possible to achieve the same with EAP-GTC via NAM client? Can anyone guide me on this regard?

While this is technically possible with Windows using NAM with EAP-GTC, it is a terrible user experience. Any time the user disconnects/reconnects or transitions between wired and wireless, they will be prompted for their user credentials and MFA.

The MacOS supplicant does not support EAP-GTC, so it is not possible on MacOS.
