# 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>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/initial-installation/1.-instructions-by-platform/virtual-self-hosted-installation/virtual-vmware/configuring-passtrough-interfaces-on-vmware.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
