NSX Data Center for vSphere requires multiple ports to be open for it to operate properly.

  • If you have a cross-vCenter NSX environment and your vCenter Server systems are in Enhanced Linked Mode, each NSX Manager appliance must have the required connectivity to each vCenter Server system in the environment. In this mode, you can manage any NSX Manager from any vCenter Server system.
  • When you are upgrading from an earlier NSXversion to version 6.4.x, Guest Introspection and host clusters must be upgraded for the Remote Desktop Session Host (RDSH) policies to be created and enforced successfully.

For the list of all supported ports and protocols in NSX 6.4.0 and later, see the VMware Ports and Protocols portal at https://ports.vmware.com/home/NSX-Data-Center-for-vSphere. You can use this portal to download the list in either CSV, Excel, or PDF file formats.
