In 7.9.0, the Label Management tab displays the list of system and custom labels. It allows you to rename or remove a user-created custom label. System labels are defined by the system and they cannot be modified.
Rename a Label
Locate the label you want to rename, click on the vertical three dots icon on the left and select Edit. Simply change the name of the label.
Remove a Label
Locate the label you want to remove, click on the vertical three dots icon on the left and select Edit. A label can only be removed if there are no devices attached and it does not have operations associated with it. Review the list of corresponding operations, remove them before deleting the label.
