A user can assign a tag group to a policy rule in the policy creation window by selecting the General tab. A tag group is a collection of tags that can be used to identify and filter policy rules based on different criteria, such as function, location, or priority. A user can create a tag group on Panorama and assign it to a policy rule to apply the same set of tags to multiple firewalls or device groups1. To assign a tag group to a policy rule, the user needs to:
Select the General tab in the policy creation window.
Click the Tag Group drop-down menu and select the tag group that the user wants to assign to the policy rule.
Click OK to save the changes. The policy rule will inherit the tags from the tag group and display them in the Tag column.
