802.1X Invalid packet code 4 sent to authentication

[Julien Bamberger]

Hello,

I have a problem between a microswitch microsens ( generation 6 ethernet 
switches) which is configured in the mode 802.1X and my serveur 
freeradius debian (2.1.12+dfsg-1.2).
I use EAP/TLS witch mac address.

I have this message :

I suppose it is the paquet format between the microswitch microsens and 
freeradius. Any ideas?

My test are okay between my freeradius and my switch cisco 2960G.

Thank's you.

Regards.

Julien.
