Version 33.4.1 adds enhanced RADIUS server handling for dot1x EAP authentication. To reduce client authentication failures during EAP-based dot1x sessions, the switch now retransmits Access-Requests to the same RADIUS server that issued the original challenge, rather than failing over to a different server. This behavior applies only to authentication retransmissions over UDP and does not affect accounting or reauthentication mechanisms.
All platforms.
