# NWEthernetChannel

An object you use to send and receive custom Ethernet frames.

## Declaration

```swift
final class NWEthernetChannel
```

## Overview

Overview Use Ethernet channels to send and receive custom Ethernet frame types over an interface. Creating Ethernet channels requires the com.apple.developer.networking.custom-protocol entitlement.
