SqlProtocolTcpIp

Parameters

Parameter	Attribute	DataType	Description	Allowed Values
InstanceName	Key	String	Specifies the name of the SQL Server instance to manage the IP address group for.
IpAddressGroup	Key	String	Specifies the name of the IP address group in the TCP/IP protocol, e.g. 'IP1', 'IP2' etc., or 'IPAll'.
ServerName	Write	String	Specifies the host name of the SQL Server to be configured. If the SQL Server belongs to a cluster or availability group specify the host name for the listener or cluster group. Default value is the current computer name.
Enabled	Write	Boolean	Specified if the IP address group should be enabled or disabled. Only used if the parameter IpAddressGroup is not set to 'IPAll'. If not specified, the existing value will not be changed.
IpAddress	Write	String	Specifies the IP address for the IP address group. Only used if the parameter IpAddressGroup is not set to 'IPAll'. If not specified, the existing value will not be changed.
UseTcpDynamicPort	Write	Boolean	Specifies whether the SQL Server instance should use a dynamic port. If not specified, the existing value will not be changed. This parameter is not allowed to be used at the same time as the parameter TcpPort.
TcpPort	Write	String	Specifies the TCP port(s) that SQL Server instance should be listening on. If the IP address should listen on more than one port, list all ports as a string value with the port numbers separated with a comma, e.g. '1433,1500,1501'. This parameter is limited to 2047 characters. If not specified, the existing value will not be changed. This parameter is not allowed to be used at the same time as the parameter UseTcpDynamicPort.
SuppressRestart	Write	Boolean	If set to $true then the any attempt by the resource to restart the service is suppressed. The default value is $false.
RestartTimeout	Write	UInt16	Timeout value for restarting the SQL Server services. The default value is 120 seconds.
IsActive	Read	Boolean	Returns $true or $false whether the IP address group is active. Not applicable for IP address group 'IPAll'.
AddressFamily	Read	String	Returns the IP address's adress family. Not applicable for IP address group 'IPAll'.
TcpDynamicPort	Read	String	Returns the TCP/IP dynamic port. Only applicable for the IP address group 'IPAll'.

Description

The SqlProtocolTcpIp DSC resource manages the TCP/IP IP address groups for a SQL Server instance.

IP Address groups are added depending on available network cards, see Adding or Removing IP Addresses. Because of that it is not supported to add or remove IP address groups.

For more information about static and dynamic ports read the article TCP/IP Properties (IP Addresses Tab).

Requirements

• Target machine must be running Windows Server 2012 or later.
• Target machine must be running SQL Server Database Engine 2012 or later.
• Target machine must have access to the SQLPS PowerShell module or the SqlServer PowerShell module.
• To configure a single IP address to listen on multiple ports, the TcpIp protocol must also set the Listen All property to No. This can be done with the resource SqlProtocol using the parameter ListenOnAllIpAddresses.
• When using the resource against an SQL Server 2022 instance, the module SqlServer v22.0.49-preview or newer must be installed.

Examples

Example 1

This example will set the TCP/IP address group IPAll to use dynamic port.

The resource will be run as the account provided in $SystemAdministratorAccount.

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [System.Management.Automation.PSCredential]
        $SystemAdministratorAccount
    )

    Import-DscResource -ModuleName 'SqlServerDsc'

    node localhost
    {
        SqlProtocolTcpIP 'ChangeIPAll'
        {
            InstanceName           = 'MSSQLSERVER'
            IpAddressGroup         = 'IPAll'
            UseTcpDynamicPort      = $true

            PsDscRunAsCredential   = $SystemAdministratorAccount
        }
    }
}

Example 2

This example will set the TCP/IP address group IPAll to use static ports.

The resource will be run as the account provided in $SystemAdministratorAccount.

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [System.Management.Automation.PSCredential]
        $SystemAdministratorAccount
    )

    Import-DscResource -ModuleName 'SqlServerDsc'

    node localhost
    {
        SqlProtocolTcpIP 'ChangeIPAll'
        {
            InstanceName           = 'MSSQLSERVER'
            IpAddressGroup         = 'IPAll'
            TcpPort                = '1433,1500,1501'

            PsDscRunAsCredential   = $SystemAdministratorAccount
        }
    }
}

Example 3

This example will set the TCP/IP address group IPAll to use static ports.

The resource will be run as the account provided in $SystemAdministratorAccount.

Configuration Example
{
