9800L Controller Software / Invalid EAPOL error

[bootleg_craig]

Users show "Invalid EAPOL(Extensible Authentication Protocol Over LANs) Key PMK" in DNA and are getting disconnected. 

9800L controller running 17.3.3

Has anyone successfully resolved this issue with a SMU ? If so, what version did you upgrade to ? 

I've seen recommendation going to 17.3.5a. Thoughts ?

Which AP model are you using?

[bootleg_craig]

APs are 9130AXI-B. Thanks for your response !

We were having EAP issues with 3702s connecting, not 9130s. We did apply an SMU to 17.3.5a and it fixed the issue we were having.

I was told that 17.3.5a was a better choice than 17.3.3 or .4c for general bug fixes. We are running it on two sets of controllers and it's been good, aside from the EAP issues. We'll move to it shortly on other controllers.
