# ReplaceNetworkAclAssociation
<a name="API_ReplaceNetworkAclAssociation"></a>

Changes which network ACL a subnet is associated with. By default when you create a subnet, it's automatically associated with the default network ACL. For more information, see [Network ACLs](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-network-acls.html) in the *Amazon VPC User Guide*.

This is an idempotent operation.

## Request Parameters
<a name="API_ReplaceNetworkAclAssociation_RequestParameters"></a>

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see [Common Query Parameters](CommonParameters.md).

 **AssociationId**   
The ID of the current association between the original network ACL and the subnet.  
Type: String  
Required: Yes

 **DryRun**   
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.  
Type: Boolean  
Required: No

 **NetworkAclId**   
The ID of the new network ACL to associate with the subnet.  
Type: String  
Required: Yes

## Response Elements
<a name="API_ReplaceNetworkAclAssociation_ResponseElements"></a>

The following elements are returned by the service.

 **newAssociationId**   
The ID of the new association.  
Type: String

 **requestId**

## Examples
<a name="API_ReplaceNetworkAclAssociation_Examples"></a>

### Example
<a name="API_ReplaceNetworkAclAssociation_Example_1"></a>

This example starts with a network ACL associated with a subnet, and a corresponding association ID `aclassoc-e5b95c8c`. You want to associate a different network ACL (`acl-5fb85d36`) with the subnet. The result is a new association ID representing the new association.
