File upload state. idle: State idle indicates that no file upload is active. Initial and final state. State transition back to idle is always initiated by the SNMP Manager and has to be possible out of any state (including idle). Upon this, the Agent resets fulResultOk to false and all the other objects to the default values listed in the file upload preconditions above. preparation: File upload preparation state, the SNMP Manager provides name and MD5 hash of the file to be uploaded. The SNMP Agent provides the upload URL. State transition to preparation is always initiated by the SNMP Manager. inProgress: State where the actual HTTP file upload takes place. State transition to inProgress is always initiated by the SNMP Manager. md5check: State after the actual HTTP file upload is finished, where the SNMP Agent verifies the upload result by a MD5 checksum test. State transition to md5check is always initiated by the SNMP Manager. md5checkDone: Upload verification is finished, SNMP Agent provides the result to the SNMP Manager (fulResultOk and fulResultString prepared accordingly by the SNMP Agent). State transition to md5checkDone is always initiated by the SNMP Agent.
