Good afternoon, I am very frustrated to get it work. I appreciate any advice! I have a very simple test environment. Laptop (WinXPpro) --------------------------- Cisco3750SW ------------------------------- Radius server (RHEL 4 with FreeRADIUS Version 2.1.6) 172.17.254.100/16 172.17.1.1/16 I have figured out how to configure attributes. Here is my "user" file: test Cleartext-Password := "test" Tunnel-Type = 16777229, Tunnel-Medium-Type = 16777222, Tunnel-Private-Group-ID = 3 When I use MD5-Challenge, I got put in the right vlan I wanted. However if I choose PEAP, I can be authenticated but the vlan thing won't work. I checked the Radius -X output very carefully and I don't see the server is sending any attributes, as it did when the MD5 is used... I chose different types of authentication on the windows box. It seems I don't have to change any configuration on the radius server for both authentications to work. I will attach both radius -X output for both types. I actually don't know if it's proper to ask questions in this email group... If I am asking at a wrong place, please tell me where I should go for asking questions like this... Thank you!! Difan
