The generic reason code why this circuit was last disconnected, as reported by the DLSw partner in a HALT_DL or HALT_DL_NOACK. If the partner does not send a reason code in these messages, or the DLSw implementation does not report receiving one, the value `unknown' is returned. This object is present only if the agent keeps circuit table entries around for some period after circuit disconnect.
