# Configuring Passtrough interfaces on VMware

For high performance ProSBC VMware systems, Passthrough mode can be enabled on network interfaces. Performance indications can be viewed here: [Requirements Matrix](/initial-installation/1.-instructions-by-platform/prosbc-requirements-matrix.md) This process requires a reboot of the host server running the VMware services.

### Configure VMware Passthrough Networking Interface

1. Log in using the Vmware web interface
2. Find MAC address of ethernet interface that will be used for passthrough:
   * Networking -> Physical NICs<br>

3. enable passthrough mode on interface
   * Host -> Manage -> Hardware -> PCI Devices -> Select Physical Network Interface -> "Toggle Passthrough"<br>

4. Reboot the host
   * Host -> Actions -> Reboot<br>

5. Add PCI device to the ProSBC instance
   * Select the ProSBC instance -> Edit -> "Add Other Device" -> PCI Device<br>

   * Select the Ethernet interface to be used in passthrough mode<br>

6. Launch the ProSBC instance
   * When selecting the interfaces in the network interface roles, use the appropriate MAC address from first step for the LAN/WAN interface. You may also notice that the device name is not "E1000" or "VMXNET" but a real Physical interface name.<br>
