The following figure shows the Cisco Nexus 1000V network topology with vCloud Director.

See the Cisco Nexus 1000V and VMware Compatibility Information for information on the version
the vCloud Director and vShield Manager for Cisco Nexus 1000V.
When a cloud administrator creates networks on demand within the vCloud Director, vShield Manager issues requests to NSM to create networks based on network pools in the vCloud Director. NSM exposes a set of APIs which enables vShield Manager to create a port profile on the Cisco Nexus 1000V.
The network administrator creates network segmentation policies that contain a tenant ID retrieved from vCloud Director, a backing type (Segmentation or VLAN), and a reference to a port profile that may contain policies for various Cisco Nexus 1000V features. These network segmentation policies are inherited on a port profile as a result of a network that is created in the vCloud Director. For more information on network segmentation policies, see Creating Network Segmentation Policies.
When networks are created in the vCloud Director, the tenant ID of the Organization and the relevant network pool parameters are sent to the vShield Manager. The vShield Manager then issues a request create networks to the Network Segmentation Manager comprising with these parameters and then, the appropriate network segmentation policy is applied.
