# AWS::GlobalAccelerator::EndpointGroup PortOverride
<a name="aws-properties-globalaccelerator-endpointgroup-portoverride"></a>

Override specific listener ports used to route traffic to endpoints that are part of an endpoint group. For example, you can create a port override in which the listener receives user traffic on ports 80 and 443, but your accelerator routes that traffic to ports 1080 and 1443, respectively, on the endpoints.

For more information, see [ Port overrides](https://docs.amazonaws.cn/global-accelerator/latest/dg/about-endpoint-groups-port-override.html) in the *Amazon Global Accelerator Developer Guide*.

## Syntax
<a name="aws-properties-globalaccelerator-endpointgroup-portoverride-syntax"></a>

```
{
  "[EndpointPort](#cfn-globalaccelerator-endpointgroup-portoverride-endpointport)" : Integer,
  "[ListenerPort](#cfn-globalaccelerator-endpointgroup-portoverride-listenerport)" : Integer
}
```

### YAML
<a name="aws-properties-globalaccelerator-endpointgroup-portoverride-syntax.yaml"></a>

```
  [EndpointPort](#cfn-globalaccelerator-endpointgroup-portoverride-endpointport): Integer

```

## Properties
<a name="aws-properties-globalaccelerator-endpointgroup-portoverride-properties"></a>

`EndpointPort`  <a name="cfn-globalaccelerator-endpointgroup-portoverride-endpointport"></a>
