Fusion OpenStack Neutron Network docking VMware, which is wrong?

A. FusionSphere OpenStack Neutron Network docking VMware needs to deploy neutron-vc- vswitchagent to dock vCenter Server.

B. FusionSphere OpenStack Neutron's neutron-vc-vswitch-agent docking vCenter Server implement converts the neutron network model to VMware network model.

C. FusionSphere OpenStack Neutron Network docking VMware supports both VLAN and VxLAN-type networks.

D. FusionSphere OpenStack Neutron Network docking VMware's Neutron's Physicalnetwork has the same name as VMware VSS.

The software defines the network, through the network device control plane separate from the data plane, thus realizing the flexible control of network traffic and making the network more intelligent as a pipeline.
