NAC Gateway 

802.1x user attempts to login using incorrect Radius credentials. 

The login attempt fails, and the user is rejected by the NAC Gateway as expected.
Additional login attempts using correct credentials are also rejected by the NAC Gateway. 

For the C3, upgrade to firmware or higher.
For the C2, upgrade to firmware or higher.
For the B3, upgrade to firmware or higher.
For the B2, upgrade to firmware or higher.
For the D-Series, upgrade to firmware or higher. 

Release notes state, in the 'Firmware Changes and Enhancements' section:
10396  Corrected an issue whereby after an initial invalid RADIUS request fails, subsequent valid requests were rejected for the same user due to caching of the initial RADIUS state attribute.

Also upgrade NAC Gateways to version or higher.
