# VZNetworkDeviceConfiguration

The common configuration traits for network devices.

```
class VZNetworkDeviceConfiguration
```

## Overview

Don’t instantiate the [`VZNetworkDeviceConfiguration`](/documentation/Virtualization/VZNetworkDeviceConfiguration) class directly. Instead, instantiate one of its subclasses, such as [`VZVirtioNetworkDeviceConfiguration`](/documentation/Virtualization/VZVirtioNetworkDeviceConfiguration). Then use the properties of this class to configure the network device.

## Topics

### Setting configuration attributes

[`attachment`](/documentation/Virtualization/VZNetworkDeviceConfiguration/attachment)

The object that defines how the virtual network device communicates with the host system.

[`macAddress`](/documentation/Virtualization/VZNetworkDeviceConfiguration/macAddress)

The media access control (MAC) address to assign to the network device.
