Result Handler is for initiating an action upon the conclusion of an operation. For example, consider the backup operation. After successful completion of backup or in the event of failure of backup, you may configure the ResultHandler of DeviceExpert to automatically initiate an action - sending an email to the desired recipients or rolling back to baseline configuration.
You can add ResultHandlers for backup and download operations and for conditions success and failure.
Note: In DeviceExpert 4.2 release, a more powerful Change Management feature has been added. The "Result Handler" feature will be removed in the next release. So, "Add Result Handler" has been removed. The following help contents are to help the users of previous versions. |

The Result Handler functionality could be put to use to achieve various applications. Two such applications have been described below:
When any configuration change is done to a device from Deviceexpert, you can receive notifications about the same by configuring the Result Handler. This can be done by configuring it in such a way that whenever a successful device download operation takes place, the Result Handler should automatically initiate sending an email to your ID.
In your production environment, you might be having some core devices to which you would not like to entertain any unauthorized configuration change. This can be achieved through the Result Handler. You might configure the Result Handler in such a way that when some configuration change takes place in a device - say a successful configuration download, you can initiate an action which rolls back the device configuration to the previous configuration or to the baseline version. This way, you can prevent unauthorized changes.
