A tag can be automatically assigned to the systems if they meet the criteria you have defined.
Select Menu → Systems → Tag Catalog.
Select the tag or tag group from the Tags list.
Click Run Tag Criteria from the Actions column.
On the Run Tag Criteria window, select whether to reset manually tagged and excluded systems.
Resetting manually tagged and excluded systems removes the tag from systems that don't match the criteria, and applies the tag to systems that match criteria but were excluded from receiving the tag.
Click OK.
The number of systems to which the tag is applied is displayed at the bottom of the page.
The tag is applied to all systems that match the criteria.
