   From RFC 2866, the termination causes are as follows:

   User Request         User requested termination of service, for
                        example with LCP Terminate or by logging out.

   Lost Carrier         DCD was dropped on the port.

   Lost Service         Service can no longer be provided; for
                        example, user's connection to a host was
                        interrupted.

   Idle Timeout         Idle timer expired.

   Session Timeout      Maximum session length timer expired.

   Admin Reset          Administrator reset the port or session.




 
RFC 4005       Diameter Network Access Server Application    August 2005


   Admin Reboot         Administrator is ending service on the NAS,
                        for example, prior to rebooting the NAS.

   Port Error           NAS detected an error on the port that
                        required ending the session.

   NAS Error            NAS detected an error (other than on the
                        port) that required ending the session.

   NAS Request          NAS ended the session for a non-error reason not
                        otherwise listed here.

   NAS Reboot           NAS ended the session to reboot
                        non-administratively ("crash").

   Port Unneeded        NAS ended the session because resource usage
                        fell below a low-water mark (for example, if
                        a bandwidth-on-demand algorithm decided that
                        the port was no longer needed).

   Port Preempted       NAS ended the session to allocate the
                        port to a higher priority use.

   Port Suspended       NAS ended the session to suspend a virtual
                        session.

   Service Unavailable  NAS was unable to provide requested service.

   Callback             NAS is terminating the current session
                        to perform callback for a new session.

   User Error           Input from user is in error, causing
                        session termination.

   Host Request         Login Host terminated session normally.

9.3.6.  Origin-AAA-Protocol

   The Origin-AAA-Protocol AVP (AVP Code 408) is of the type Enumerated
   and should be inserted in a Diameter message translated by a gateway
   system from another AAA protocol, such as RADIUS.  It identifies the
   source protocol of the message to the Diameter system receiving the
