newest batch of LAP's wont register with the WiSM

Unanswered Question
Aug 3rd, 2010

Im getting this error.

User authentication from Controller '' failed for User name '5475d0972c16' and user type 'Network User'.

that mac is one of the new AP's. Nothing has been changed at all on WCS or the controllers.....There are 3 1242's and an 1131 out there that just flatly refuses to register...I dont quite understand that error, maybe its a proxy'ed client association request.

We are registering to the controller via the hostname (not option 43) and everything has gone perfectly until now. Where do I start?

I have this problem too.

I did find this error

*Aug 03 11:30:20.656: %DTLS-3-HANDSHAKE_FAILURE: openssl_dtls.c:2171 Failed to complete DTLS handshake with peer

and a forum search shows this is indicative of a trunking problem, there the AP is on an access port....

Can you provide the following information:

1.  Can you kindly post the "sh version" of the APs?

2.  LWAPs should be connected to an Access Port and WLC should be connected to a Trunk Port and VLANs allowed on the LWAP VLAN.

3.  What version is your WiSM?
