ISE is using 3.2 Patch 5.
I'm doing TACACS authentication through ISE
I want to do 2FA authentication using OTP.
DUO confirmed that it is possible, but I understand that it costs extra.
So I'm looking into whether there's any other way.
Among them, I wonder if Google Authenticator can support that feature.
And if there is any other way, please let me know.
