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 : Thu Jan 29 11:26:30 2015 : Debug: Invalid packet code 4 sent to authentication port from client 192.168.83.105 port 45804 : IGNORED Thu Jan 29 11:26:30 2015 : Info: Ready to process requests.

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.
