# AWS::MediaConnect::RouterInput FailoverRouterInputConfiguration
<a name="aws-properties-mediaconnect-routerinput-failoverrouterinputconfiguration"></a>

Configuration settings for a failover router input that allows switching between two input sources.

## Syntax
<a name="aws-properties-mediaconnect-routerinput-failoverrouterinputconfiguration-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-mediaconnect-routerinput-failoverrouterinputconfiguration-syntax.json"></a>

```
{
  "[NetworkInterfaceArn](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-networkinterfacearn)" : String,
  "[PrimarySourceIndex](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-primarysourceindex)" : Integer,
  "[ProtocolConfigurations](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-protocolconfigurations)" : [ FailoverRouterInputProtocolConfiguration, ... ],
  "[SourcePriorityMode](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-sourceprioritymode)" : String
}
```

### YAML
<a name="aws-properties-mediaconnect-routerinput-failoverrouterinputconfiguration-syntax.yaml"></a>

```
  [NetworkInterfaceArn](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-networkinterfacearn): String
  [PrimarySourceIndex](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-primarysourceindex): Integer
  [ProtocolConfigurations](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-protocolconfigurations): 
    - FailoverRouterInputProtocolConfiguration
  [SourcePriorityMode](#cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-sourceprioritymode): String
```

## Properties
<a name="aws-properties-mediaconnect-routerinput-failoverrouterinputconfiguration-properties"></a>

`NetworkInterfaceArn`  <a name="cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-networkinterfacearn"></a>
The ARN of the network interface to use for this failover router input.  
*Required*: Yes  
*Type*: String  
*Pattern*: `^arn:(aws[a-zA-Z-]*):mediaconnect:[a-z0-9-]+:[0-9]{12}:routerNetworkInterface:[a-z0-9]{12}$`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`PrimarySourceIndex`  <a name="cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-primarysourceindex"></a>
The index (0 or 1) that specifies which source in the protocol configurations list is currently active. Used to control which of the two failover sources is currently selected. This field is ignored when sourcePriorityMode is set to NO\$1PRIORITY  
*Required*: No  
*Type*: Integer  
*Minimum*: `0`  
*Maximum*: `1`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ProtocolConfigurations`  <a name="cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-protocolconfigurations"></a>
A list of exactly two protocol configurations for the failover input sources. Both must use the same protocol type.  
*Required*: Yes  
*Type*: Array of [FailoverRouterInputProtocolConfiguration](aws-properties-mediaconnect-routerinput-failoverrouterinputprotocolconfiguration.md)  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`SourcePriorityMode`  <a name="cfn-mediaconnect-routerinput-failoverrouterinputconfiguration-sourceprioritymode"></a>
The mode for determining source priority in failover configurations.  
*Required*: Yes  
*Type*: String  
*Allowed values*: `NO_PRIORITY | PRIMARY_SECONDARY`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
