This read-create ShapingType specifies whether network-to-access traffic on the Ethernet Flow is shaped by port-level or flow-level shapers. The value is fixed and not changeable for a port-based flow, though regular and default flows on FSP150 products may support either mode. For example, an administrator configures a default flow's N2A shaping as port-level so its download rate is governed by the shared port shaper rather than a dedicated flow shaper.
