The authentication failed becuase the switch did not get a response.

Put a sniffer (Ethereal) between the switch and the IAS server to
confirm that this is the case. You should see a packet go out to the
IAS server and then see no reply packet.
If that is the case then the problem is on the IAS server

RADIUS uses UDP port 1812 by default ( or the port configured in teh
IOS config)

Does the IAS server have a default gateway configured ?


IAS Server has default gateway and if I try login just from IAS Server it always has success. And I was wondering, why I can login from my host after I login from host which is in the same VLAN as IAS Server? Maybe ip radius source-interface command should help... Now I set this command and see if it helps. But to check it out, I need some time.
