The following activities are performed by NAS: • responds with DM-Nak, if no matching session is found in NAS for the session identification attributes in DM; Error-Cause value is "Session Context Not Found" (503). • responds with DM-Nak for any internal processing error in NAS; Error-Cause value is "Resources Unavailable" (506). • ignores attributes that are supported as per RFC but are irrelevant to the DM operation. • responds to a disconnect message containing one or more incorrect attributes values with a Disconnect-NAK; Error-Cause value is "Invalid Attribute Value" (407). • responds to a disconnect message containing unsupported attributes with DM-Nak; Error-Cause value is "Unsupported Attributes" (401). NOTE: Unsupported attributes are the ones that are not mentioned in the RFC 5176 but present in the disconnect message that is received by the NAS. • rejects the disconnect message containing NAS-IP-Address or NAS-IPV6-Address attribute that does not match NAS with DM-Nak; Error-Cause value is "NAS Identification Mismatch" (403). • responds with a DM-Nak, if the NAS is configured to prohibit honoring of disconnect messages; Error-Cause value is "Administratively Prohibited" (501).
