Hi yhkim,
This message is more of a warning to say that the request contained an unexpected attribute, but processing continues as if the attribute wasn't there.
An "EAP identity response" is the first request that the RADIUS server receives from the RADIUS client in an EAP handshake. That being the case, it is not expected to include a State attribute, which the RADIUS server generates for access -challenge responses in order to manage the handshake.
The fact that the state is there indicates that the access point/authenticator (radius client) is having trouble managing the EAP handshake, possibly due to timeouts. Check for firmware upgrades and/or eap timer settings on the AP which may be set too low.
If the problem persists, you might arrange a call between the radius client vendor and JTAC to help get it sorted out.
Regards,
Brian
