### Modifying Data Transfer Settings to Change Number of TCP/IP Connections

This example shows how to modify data transfer settings and change a number of TCP/IP connections per job session. The cmdlet will return details about the modified data transfer settings.

```
$transfersettings = Get-VBRUploadStreamsConfiguration
Set-VBRUploadStreamsConfiguration -Configuration $transfersettings -StreamCount 7 -PassThru
                                  Enabled                                                 StreamCount
                                  -------                                                 -----------
                                     True                                                           7
```

Perform the following steps:

1. Run the [`Get-VBRUploadStreamsConfiguration`](get-vbruploadstreamsconfiguration.md) cmdlet. Save the result to the `$transfersettings` variable.
2. Run the `Set-VBRUploadStreamsConfiguration` cmdlet. Set the `$transfersettings` variable as the `Configuration` parameter value. Specify the `StreamCount` parameter value. Provide the `PassThru` parameter.
