+  [Roll back a policy version](iam_example_iam_Scenario_RollbackPolicyVersion_section.md) 

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

**AWS CLI**  
**To set the specified version of the specified policy as the policy's default version.**  
This example sets the `v2` version of the policy whose ARN is `arn:aws:iam::123456789012:policy/MyPolicy` as the default active version.  

```
aws iam set-default-policy-version \
    --policy-arn arn:aws:iam::123456789012:policy/MyPolicy \
    --version-id v2
```
For more information, see [Policies and permissions in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) in the *AWS IAM User Guide*.  
+  For API details, see [SetDefaultPolicyVersion](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/iam/set-default-policy-version.html) in *AWS CLI Command Reference*.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example sets the `v2` version of the policy whose ARN is `arn:aws:iam::123456789012:policy/MyPolicy` as the default active version.**  

```
Set-IAMDefaultPolicyVersion -PolicyArn arn:aws:iam::123456789012:policy/MyPolicy -VersionId v2
```
+  For API details, see [SetDefaultPolicyVersion](https://docs.aws.amazon.com/powershell/v4/reference) in *AWS Tools for PowerShell Cmdlet Reference (V4)*. 

**Tools for PowerShell V5**  
**Example 1: This example sets the `v2` version of the policy whose ARN is `arn:aws:iam::123456789012:policy/MyPolicy` as the default active version.**  

```
Set-IAMDefaultPolicyVersion -PolicyArn arn:aws:iam::123456789012:policy/MyPolicy -VersionId v2
```
