Hi All, i have a Testbed with following Scenario: Intel 4965agn n-Mode, EAP FAST /w AES => AP1252 => WLC4404, Rel. 4.2 => Cisco Secure ACSSE 4.1
The Client is not able to connect to the WLAN. The Controller Message Log shows as follows:
Mar 07 13:11:16.327 1x_kxsm.c:1124 DOT1X-3-WPA_SEND_STATE_ERR: Unable to send EAPOL-key msg - invalid WPA state (0) - client 00:1d:e0:6f:cb:43
The Cisco Secure ACS "Failed Attempts" Report shows: Authentication Failed/ ACS User Unknown. The User is properly configured in ACS.
I checked the Cisco Wireless LAN Controller System Message Guide, it shows:
Error Message %DOT1X-3-WPA_SEND_STATE_ERR: Unable to send EAPOL-key msg - invalid
WPA state ([int]) - client [hex]:[hex]:[hex]:[hex]:[hex]:[hex]
Explanation Client authentication failed because the session was not in the correct state when attempting to send an EAPOL-key message.
Has anybody seen this before and can help me solving my Problem? How can i influence the "Correct WPA Session State"?
