Hi,All! My freeradius version is v2.0.2,and I use cisco 2950 switch as Authenticator; the packet sent by server miss the EAP-TLS Fragments(server sent a packet which miss the server hello and ciper suilt messages after received a client hello packet),I don't kown what the prolbem.Can anybody help me? Here are the packets,the ip of radius server is:192.168.0.197,the ip of switch is:192.168.0.123.
