Add Tag elements to Situation elements

You can use Tag elements to group Situation elements and Situation Type elements to classify Situations.

You can use predefined Tags or create new ones according to any criteria (for example, create a Tag for grouping together related services). Situation Types are predefined, and you cannot create new Situation Types. You can associate multiple Tags with one Situation, but only one Situation Type can be associated with each Situation.

You can use the Tags and/or Situation Types to represent a group of Situations in the Rules and Exceptions of the Inspection Policy. This allows you to match a rule to all Situations that contain the Tag or Situation Type. Situations that are associated with a Situation Type are automatically included in the Rules tree.

When you are editing the Situation properties, you can add tags.
Note: If a Tag or Situation Type you add to a Situation is in use in some Inspection Policy, the new Situation is automatically included in the policy when you save the Situation. The engines start matching traffic to the Situation when you refresh the policy.
