Error 201 is defined. However, RFC 5716 only defines to how modify authorizations or delete current sessions. Presumably if a session were not active, then current implementations would return a Disconnect-NAK or CoA-NAK, rather than a Disconnect-ACK with Error-Code value 201. > From: glenzorn@comcast.net > To: Bernard_Aboba@hotmail.com; mchiba@cisco.com; radiusext@ops.ietf.org > Subject: RE: inconsistency in RFC 5176 > Date: Fri, 15 Feb 2008 12:19:27 +0700 > > Bernard Aboba <> scribbled on Friday, February 15, 2008 6:07 AM: > > > There is no contradiction here.
