I want do use the Cisco ACS for 802.1x authentication with a Third Party Switch (Alcatel). With a Cisco switch everything works fine. This is also true with the Alcatel Switch as long as I set the Radius Type in the ACS to IETF. Put for some purpose I need VSAs (RADIUS Vendor-Specific Attributes). So I created my on VSA Import File and imported it with the "CsUtil.exe" command in the ACS. Then I configured the ACS to use this new Radius Type for my Third Party Switch. Now the Authentication don't work anymore. In the "Failed Attempts"-Log of the ACS I can find the following entry: "Bad request from NAS".
Any Idea what is going wrong?
