802.1x EAP type not configured

Unanswered Question
Jan 24th, 2008

Hi, a simple 802.1x test with XP client sp2, 3560 with IOS 12.2(35)SE5 and ACS 4.1(1) build 23.

EAP MD5 selected on the client and enabled on the ACS but I receive in ACS an authentication failure message, with Authen-Failure-Code "EAP type not configured".

Any idea ?

thank you in advance


I have this problem too.

You have to install a self-generated certificate on the ACS, and enabled PEAP with "Allow EAP-MSCHAPv2". then changed the setting on our PC, and manage to make it work.

Could you do the following,

1.) Enable full detail logging on the ACS: System Configuration -> Service

Control -> Logging detail level = "FULL". Then restart the ACS services.

2.) Enable "debug radius" together with the debugs that you already have

on the switch

3.) If there is a sniffer (Norton SnifferPro, or the freeware Wireshark or

Ethereal) on the client laptop, please start it and enable sniffing on the

client interface.

4.) Make another authentication attempt.

5.) Generate a "package.cab" on the ACS, by running Bin\CSSupport.exe

underneath the ACS installation directory

6.) Please send me the following information,

a) The package.cab file,

b) the debug output from the switch,

c) the sniffer trace (if available).
