Before installing NCP, you need to set up some NSX-T resources.

The NSX Manager web UI provides 2 methods to configure some networking resources.
  1. The Networking tab. From this tab, you can configure segments, gateways, IP blocks, IP pools, and other objects. The UI in this tab is also known as the policy UI. With this method, if you use the API to configure networking, you must use the policy API calls. In the API reference, these calls have the URI path /policy/api/v1/....
  2. The Advanced Networking & Security tab. From this tab, you can configure logical switches, logical routerss, IP blocks, IP pools, and other objects. The UI in this tab is also known as the manager UI. With this method, if you use the API to configure networking, you must use the manager API calls. In the API reference, these calls have the URI path /api/v1/....

You must use one of the two methods to configure NSX-T networking for NCP, but not both. You must set the policy_nsxapi option in the NCP YAML file to True if you use the policy UI, or False if you use the manager UI.

The following sections assume that you are familiar with installing and administering NSX-T Data Center. For more information, see the NSX-T Data Center Installation Guide and the NSX-T Data Center Administration Guide.
