Site Recovery Manager can protect virtual machines that are attached to NSX networks present on the protected and recovery site without having to configure inventory mappings.

NSX Data Center for vSphere supports Universal Logical Switches which allow for the creation of layer-2 networks that span vCenter Server boundaries. When using Universal Logical Switches with NSX, there is a virtual port group at both the protected and recovery site that connects to the same layer-2 network. This means that when using storage policy protection groups and a Universal Logical Switch, you do not need to specify any network mapping. Site Recovery Manager works with NSX Data Center for vSphere to automatically map the virtual machine to the correct network at the recovery site.

You can override auto-mapping by manually configuring network mappings on stretched networks. Enhanced Linked Mode and non- Enhanced Linked Mode topologies are supported.


  • Auto-mapping for NSX universal wires is only supported with storage policy protection groups and Universal Logical Switches.
  • Network auto-mapping for storage policy protection groups is not supported on VMware NSX-T™ Data Center.
  • For virtual machine protection groups, you must explicitly configure network mapping between the two ends of the universal wire to ensure that the virtual machines recover on the same universal wire.
  • This feature is only supported for a full recovery. Test failover must be done manually.

See Configure Inventory Mappings for details.
