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 the Cisco Nexus 1000V.
When a cloud administrator creates networks on demand within vCloud Director, vShield Manager issues requests to NSM to create networks based on network pools in vCloud Director. NSM exposes a set of APIs that 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 that is 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 vCloud Director. For more information about network segmentation policies, see Creating Network Segmentation Policies.
When networks are created in vCloud Director, the tenant ID of the organization and the relevant network pool parameters are sent to vShield Manager. vShield Manager then issues a request to create networks to Network Segmentation Manager and then the appropriate network segmentation policy is applied.
