Packets that are explicitly ‛out-of-profile’ remain ‛out-of-profile in the ingress forwarding plane. Unlike initially ‛in-profile’ packets, they do not consume the policer’s CIR bucket depth (accomplished by setting the ‛threshold-bc’ to 0) and therefore do not have an impact on the amount of ‛undefined’ marked as ‛in-profile’ by the policer.
While explicit ‛out-of-profile’ packets remain out-of-profile within the ingress forwarding plane, the egress forwarding plane treats ingress out-of-profile packets as ‛soft-out-of-profile’ and the profile may be changed either by explicit profile reclassification or by an egress policer with a CIR rate defined.
