<a name="elastic-load-balancing-v2_example_elastic-load-balancing-v2_ModifyLoadBalancerAttributes_section"></a>

The following code examples show how to use `ModifyLoadBalancerAttributes`.

------
#### [ CLI ]

**AWS CLI**  
**To enable deletion protection**  
This example enables deletion protection for the specified load balancer.  
Command:  

```
aws elbv2 modify-load-balancer-attributes --load-balancer-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188 --attributes Key=deletion_protection.enabled,Value=true
```
Output:  

```
{
  "Attributes": [
      {
          "Value": "true",
          "Key": "deletion_protection.enabled"
      },
      {
          "Value": "false",
          "Key": "access_logs.s3.enabled"
      },
      {
          "Value": "60",
          "Key": "idle_timeout.timeout_seconds"
      },
      {
          "Value": "",
          "Key": "access_logs.s3.prefix"
      },
      {
          "Value": "",
          "Key": "access_logs.s3.bucket"
      }
  ]
}
```
**To change the idle timeout**  
This example changes the idle timeout value for the specified load balancer.  
Command:  

```
aws elbv2 modify-load-balancer-attributes --load-balancer-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188 --attributes Key=idle_timeout.timeout_seconds,Value=30
```
Output:  

```
{
  "Attributes": [
      {
          "Value": "30",
          "Key": "idle_timeout.timeout_seconds"
      },
      {
          "Value": "false",
          "Key": "access_logs.s3.enabled"
      },
      {
          "Value": "",
          "Key": "access_logs.s3.prefix"
      },
      {
          "Value": "true",
          "Key": "deletion_protection.enabled"
      },
      {
          "Value": "",
          "Key": "access_logs.s3.bucket"
      }
  ]
}
```
**To enable access logs**  
This example enables access logs for the specified load balancer. Note that the S3 bucket must exist in the same region as the load balancer and must have a policy attached that grants access to the Elastic Load Balancing service.  
Command:  

```
aws elbv2 modify-load-balancer-attributes --load-balancer-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/my-load-balancer/50dc6c495c0c9188 --attributes Key=access_logs.s3.enabled,Value=true Key=access_logs.s3.bucket,Value=my-loadbalancer-logs Key=access_logs.s3.prefix,Value=myapp
```
Output:  

```
{
  "Attributes": [
      {
          "Value": "true",
          "Key": "access_logs.s3.enabled"
      },
      {
          "Value": "my-load-balancer-logs",
          "Key": "access_logs.s3.bucket"
      },
      {
          "Value": "myapp",
          "Key": "access_logs.s3.prefix"
      },
      {
          "Value": "60",
          "Key": "idle_timeout.timeout_seconds"
      },
      {
          "Value": "false",
          "Key": "deletion_protection.enabled"
      }
  ]
}
```
