This scenario describes typical tasks used to configure a hardware gateway switch with an NSX deployment. The sequence of tasks show how to connect the virtual machine VM1 to the physical server and to connect the WebService logical switch to the VLAN-Server VLAN 160 using the hardware gateway.

The sample topology shows that virtual machine VM1 and VLAN-Server are configured with an IP address in the subnet 10. VM1 is attached to WebService logical switch. The VLAN-Server is attached to VLAN 160 on the physical server.

Sample tolpology that shows a VM and VLAN server configured on the subnet 10.
Important: In a cross-vCenter NSX environment, hardware gateway switch configurations are supported on the primary and secondary NSX Manager and multiple replication clusters. However, only hardware gateways on a primary NSX manager can use the default replication cluster. On a secondary NSX manager, new replication clusters for hardware gateways should be created. Hardware gateway switches must be bound to non-universal logical switches.


  • Read the vendor documentation to meet the physical network requirements.
  • Verify that you meet the NSX system and hardware requirements for hardware gateway configuration. See System Requirements for NSX Data Center for vSphere.
  • Verify that the logical networks are set up properly. See the NSX Installation guide.
  • Verify that the transport parameter mappings in the VXLAN are accurate. See the NSX Installation guide.
  • Retrieve the vendor certificate for your hardware gateway.
  • Verify that the VXLAN port value is set to 4789. See Change VXLAN Port.
