Keep in mind that when you configure a VLAN in Acropolis, it doesn't program it to any sort of OVS until a VM is provisioned on a host. When that happens, we configure a Tap device on that OVS, and program the VLAN to that tap device.
Completely different construct from the typical vSwitch, where you program the vSwitch, then attach VM's to pre-configured "port groups".
Traffic shaping it not yet available. If you have a use case for it, please submit a support ticket with priority RFE Request for Enhancement, so we can track demand for the feature.
