<DIV> I 'd like to add some infos about this issue. TLS/wired is failed,but MD5/wired is successful.</DIV>
<DIV> It's Ok when I use AP instead of switch authenticating eap/tls and eap/ttls with the same freeradius.</DIV>
<DIV> Is it the problem of switch or the problem of radius? </DIV>
<DIV> I think it's the problem of radius server,because md5 can authenticate successful,</DIV>
<DIV> that means 802.1X works properly on switch. So how to configure freeradius as wired authentication?</DIV>
<DIV> I don't use sql, I just add some items at the end of the users file,just like this:</DIV>
<DIV> switch_client Cleartext-Password :="whatever"</DIV>

<DIV>Hi,All!<BR> 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?</DIV>
<DIV>Here are the packets,the ip of radius server is:192.168.0.197,the ip of switch is:192.168.0.123.</DIV>
