[<CommonParameters>] Description
The Add-RemoteAccessRadius cmdlet adds a new external RADIUS server for one of the following purposes:
-- Accounting Radius configuration applies to both DirectAccess (DA) and VPN.
-- One-time password (OTP) RADIUS configuration applies only to DA.
-- Authentication Radius configuration applies only to VPN.
Radius server configuration for Accounting and OTP are global in nature, such as the configurations apply to the entire Remote Access deployment. RADIUS server configuration for VPN applies only to a specific VPN server, and all servers in a load balancing cluster, or if multi-site is deployed, to all VPN servers at a site.
Following describes aspects of this cmdlet behavior.
-- If a RADIUS server is currently being used for a specific purpose, then it can be added for additional purpose using this cmdlet.
-- The RADIUS server properties for authentication and accounting are the same except for the AccountingOnOffMsg parameter which is applicable only to accounting RADIUS and the MsgAuthenticator parameter which is applicable only to authentication RADIUS. These properties are not relevant for DA OTP authentication.
-- If a user tries to add a RADIUS server for a particular purpose but specifies a parameter that is not applicable to that purpose, then this cmdlet will still run but the parameter will be ignored and a warning message will be issued. When adding a RADIUS server for OTP authentication both the above described parameters are ignored if specified.
-- If the accounting configuration is Windows Server® 2012 accounting, then a user can switch to external RADIUS accounting by adding an external RADIUS server for the purpose of accounting.
-- Following are some pre-requisites for adding a RADIUS server.
---- A RADIUS server cannot be added for authentication when VPN is not even installed.
---- A RADIUS server cannot be added for authentication when the authentication type is Windows or when local NPS is installed.
---- A RADIUS server cannot be added for the purpose of accounting when external RADIUS accounting is not enabled.
---- A RADIUS server cannot be added for purpose of OTP authentication if OTP authentication is not enabled.

Parameters
-AccountingOnOffMsg
Indicates the enabled state for sending of accounting on or off messages. The acceptable values for this parameter are:
-- Enabled.
-- Disabled. This is the default value. This parameter is applicable only when the RADIUS server is being added for Remote Access accounting.
| Type: | String |
| Accepted values: | Enabled, Disabled, |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
| Type: | CimSession[] |
| Aliases: | Session |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ComputerName
Specifies the IPv4 or IPv6 address, or host name, of the computer on which the remote access server computer-specific tasks should be executed. If this parameter is specified when adding a RADIUS server for authentication, then it is added for the VPN server represented by this parameter value.
| Type: | String |
| Aliases: | Cn |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-EntrypointName
Specifies the identity of a site in a multi-site deployment. This parameter is applicable only to RADIUS server configuration for VPN authentication. It is not applicable to RADIUS accounting and OTP and hence is ignored when a user tries to add a radius server for these purposes.
When this parameter is specified it indicates that the RADIUS server for VPN authentication should be added for that site.
If this parameter is not specified in a multi-site deployment, then this parameter value for the server on which the cmdlet is run is used. The server could also be represented by using the ComputerName parameter.
If this parameter and ComputerName parameter are specified and the ComputerName parameter value does not belong to the site represented by this parameter value, then this parameter takes precedence and the RADIUS server is added to it.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-MsgAuthenticator
Specifies the enabled state for the usage of message authenticator. The acceptable values for this parameter are:
-- Enabled.
-- Disabled. This is the default value.
This parameter is applicable only when the RADIUS server is being added for VPN authentication.
| Type: | String |
| Accepted values: | Enabled, Disabled, |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |

| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet.
If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.
The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Inputs
Outputs
The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects.
The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
The RemoteAccessRadiusServer object array consists of the following properties:
-- IPv4 or IPv6 address, or host name, of the RADIUS server that was added.
-- The Purpose for which the server was added property: the RADIUS server can be added for VPN authentication, accounting or OTP.
-- Radius initial score.
-- Radius timeout in seconds.
-- Radius port number.
-- For added security, the Radius shared secret property is never populated; it will always show as blank.
-- The Status of accounting on and off messages property is always blank if the RADIUS server was added for authentication or OTP.
-- The Status of message authenticator property is always blank if the RADIUS server was added for accounting or OTP.
