This read-write object, used by classifiers within the Diffserv Rules table, lets the classifier apply to outbound traffic on all Diffserv boundary ports or all Diffserv interior ports collectively rather than the single port named in rlPolicyClassifierOutIfIndex, which is used only when this is set to 'normal'. An admin uses this to write one egress-side classifier rule covering an entire class of ports instead of one per port. For example, an admin enforcing consistent Diffserv remarking on egress from all interior ports would set this to allInterior rather than listing each interior port individually.
