You now have a configured primary NSX Manager and at least one secondary NSX Manager. In addition to creating universal objects from the primary NSX Manager, you can also create objects that are local to that specific vCenter NSX environment, such as logical switches, and logical (distributed) routers. These can be created on primary or secondary NSX Managers. They will exist only within the vCenter NSX environment in which they were created. They will not be visible on the other NSX Managers in the Cross-vCenter NSX environment. Additionally, you can add hosts to or remove hosts from clusters.
See the NSX Administration Guide for details on additional administrative tasks you may want to complete.
