According to the VMware NSX Documentation, these are two of the ways that you can use to configure Distributed Firewall on VDS:

• NSX API: This is a RESTful API that allows you to programmatically configure and manage Distributed Firewall on VDS using HTTP methods and JSON payloads. You can use tools such as Postman or curl to send API requests to the NSX Manager node.
• NSX UI: This is a graphical user interface that allows you to configure and manage Distributed Firewall on VDS using menus, tabs, buttons, and forms. You can access the NSX UI by logging in to the NSX Manager node using a web browser.

According to the VMware NSX 4.x Professional documents and tutorials, an NSX Manager is a standalone appliance that hosts the API services, the management plane, control plane, and policy management. The NSX Manager has three built-in roles: policy, manager, and controller2. The policy role handles the declarative configuration of the system and translates it into desired state for the manager role. The manager role receives and validates the configuration from the policy role and stores it in a distributed persistent database. The manager role also publishes the configuration to the central control plane. The controller role implements the central control plane that computes the network state based on the configuration and topology information3. The other roles (master, cloud, and zookeeper) are not valid NSX Manager roles.

According to the VMware NSX Documentation, these are the two places where you need to configure the VLANs used in VRF Lite:

• Uplink trunk segment: This is a segment that connects a tier-0 gateway to a physical network using multiple VLAN tags. You need to configure the VLAN IDs for each VRF on this segment.
• Uplink interface of the VRF gateway: This is an interface that connects a VRF gateway to an uplink trunk segment using a specific VLAN tag. You need to configure the VLAN ID for each VRF on this interface.
