To delete a device tag:
The device tag is deleted. The deleted tag is automatically removed from all of the devices to which it was assigned.
The tag that you have deleted is not removed automatically from auto-tagging rules. After the tag is deleted, it will be assigned to a new device only when the device first meets the conditions of a rule that assigns the tag.
The deleted tag is not removed automatically from the device if this tag is assigned to the device by an application or Network Agent. To remove the tag from your device, use the klscflag utility.
