# nw_ethernet_channel_t

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

## Declaration

```swift
typealias nw_ethernet_channel_t = any OS_nw_ethernet_channel
```

## Discussion

Discussion 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.
