This read-create object specifies what action to apply to traffic matching this Access Control Entry, such as permit, deny, or another supported ACE action. An admin defines this as the actual enforcement outcome of a classification rule; everything else in the ACE, like its tuples and type, is about matching, while this field decides what happens to matched traffic. For example, an admin building a rule to block a known malicious IP range would set this ACE's action to deny so any matching traffic is dropped rather than forwarded.
