# Port Speed

Configuring port speed and operation is most commonly done with PoE access switches however the same configurations are possible for all OpenWiFi device types.&#x20;

By default all ports attempt 1,000 Mb/s full duplex operation.&#x20;

```
 "ethernet": [
            {
                    "select-ports": [
                            "WAN1"
                    ],
                    "speed": 100,
                    "duplex": "half"
            },
            {
                    "select-ports": [
                            "WAN2"
                    ],
                    "speed": 1000,
                    "duplex": "full"
            },
            {
                    "select-ports": [
                            "WAN3"
                    ],
                    "speed": 100,
                    "duplex": "half"
            }
    ],
```
