# Use `PutFunctionConcurrency` with a CLI
<a name="lambda_example_lambda_PutFunctionConcurrency_section"></a>

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

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

**AWS CLI**  
**To configure a reserved concurrency limit for a function**  
The following `put-function-concurrency` example configures 100 reserved concurrent executions for the `my-function` function.  

```
aws lambda put-function-concurrency \
    --function-name  my-function  \
    --reserved-concurrent-executions 100
```
Output:  

```
{
    "ReservedConcurrentExecutions": 100
}
```
For more information, see [Reserving Concurrency for a Lambda Function](https://docs.aws.amazon.com/lambda/latest/dg/per-function-concurrency.html) in the *AWS Lambda Developer Guide*.  
+  For API details, see [PutFunctionConcurrency](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/lambda/put-function-concurrency.html) in *AWS CLI Command Reference*. 

------
#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example applies the concurrency settings for the Function as a whole.**  

```
Write-LMFunctionConcurrency -FunctionName "MylambdaFunction123" -ReservedConcurrentExecution 100
```

**Tools for PowerShell V5**  
**Example 1: This example applies the concurrency settings for the Function as a whole.**  

```
Write-LMFunctionConcurrency -FunctionName "MylambdaFunction123" -ReservedConcurrentExecution 100
```
