Assignement vlan with 802.1X

[albertog]

I have configured 802.1X VLAN ASSIGNEMENT VIA RADIUS.When the client is catalyst 2950 working fine, I get vlan assignement in my user, but with a 3750 12.1(22) I get the next messege in the radius:

Message-type: Bad request from NAS

Authen failure code: Invalid Message authenticator in EAP request

Can you help me ??

Hi

This message is generated when the shared secrets (on the authenicator and ACS) dont match.

The message authenticator is a hash created using the secret precisely to ensure EAP packets arent simply being replayed from traffic sniffed off another device.
