Bulk RADIUS Client Additions on Multiple Servers

This PowerShell script is used to add RADIUS clients to multiple RADIUS servers. Below is a breakdown of the script's components:

1. Synopsis: A brief description of the script's purpose.

 

2. Description: An explanation of what the script does, including that it reads RADIUS client information from a CSV file and adds them to multiple RADIUS servers while logging the results.

 

3. Notes: Includes metadata about the script, such as the file name, prerequisites, author, and date.

 

4. Example: Shows how to use the script with example parameters.

The script defines a function called Add-RADIUSClients with three parameters:

• $CsvPath: The path to the CSV file containing RADIUS client information.
• $ServerListPath: The path to a text file containing a list of RADIUS server names.
• $LogFilePath: The path to the log file where the script will log the results.

 

Within the function, it performs the following steps:

1. Imports the RADIUS client information from the CSV file.

 

2. Reads the list of RADIUS server names from the text file.

 

3. Iterates through each server and each client to add RADIUS clients to the servers.

 

4. Uses Invoke-Command to remotely execute the New-NpsRadiusClient cmdlet on each server, adding the RADIUS client.

 

5. Logs the results to the specified log file, indicating success or any errors encountered.

The Try and Catch blocks are used to handle any errors that may occur during the process, logging the error messages to the log file.

The script concludes with an example usage section, where you can specify the paths to your CSV file, server list, and log file, and then call the Add-RADIUSClients function with these parameters.

Make sure to have PowerShell Remoting enabled on the target servers and the required modules imported for the script to work as expected.
