RADIUS NAP Error Code

[GCA]

Hi, I been having event ID 16 A RADIUS message with the code field set to 12, which is not valid, was received on port 1812 from RADIUS client "AP NAME" Valid values for the RADIUS Code field are documented in the TFC 2865.

 

We have a Xirrus system which is configured to two Vlans Corp and Guest, the SSID's are setup with the radius IP and password, the Radius server has the AP name/IP/Password in the RADIUS clients but some of our AP's show "not connected" to either corp or guest or both in some cases.

 

Any suggestions??
