Managing Hostname-Changed Devices
Contents
The system uses hostname as the unique identifier for each device in a live discovery, so the device which has hostname change will be treated as a new one and re-added to a domain. It will lead to duplicated IPs and reduce topology accuracy.
Complete the following steps to identify and manage the devices with hostname change.
1.Log in to the Domain Management page.
2.In the Domain Management page, click Fine Tune on the Start Page or select Operations > Fine Tune from the quick access toolbar.
3.In the Fine Tune tab, click Hostname Change in the left pane.
1)Click Detect to list the devices with the same serial number but different hostnames.
2)Review the devices in the Confirmation List and select the check box for target serial numbers.
3)Click Keep the Latest. The old hostnames saved in some features will be updated to the new ones. See Updated Feature/File for more information about what has been updated.
Note: The Keep the Latest operation is irreversible.
