function Get-DbaTcpPort { <# .SYNOPSIS Returns the TCP port used by the specified SQL Server. .DESCRIPTION By default, this function returns just the TCP port used by the specified SQL Server. If -All is specified, the server name, IPAddress (ipv4 and ipv6), port number and an indicator of whether or not the port assignment is static are returned. Remote sqlwmi is used by default. If this doesn't work, then remoting is used. If neither work, it defaults to T-SQL which can provide only the port. .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Allows you to connect to servers using alternate Windows credentials $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. .PARAMETER Credential Credential object used to connect to the Computer as a different user .PARAMETER All If this switch is enabled, an object with server name, IPAddress (ipv4 and ipv6), port and static ($true/$false) for one or more SQL Servers is returned. .PARAMETER ExcludeIpv6 If this switch is enabled, IPv6 information is excluded from All output. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: SQLWMI, tcp Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaTcpPort .EXAMPLE PS C:\> Get-DbaTcpPort -SqlInstance sqlserver2014a Returns just the port number for the default instance on sqlserver2014a. .EXAMPLE PS C:\> Get-DbaTcpPort -SqlInstance winserver\sqlexpress, sql2016 Returns an object with server name and port number for the sqlexpress on winserver and the default instance on sql2016. .EXAMPLE PS C:\> Get-DbaTcpPort -SqlInstance sqlserver2014a, sql2016 -All Returns an object with server name, IPAddress (ipv4 and ipv6), port and static ($true/$false) for sqlserver2014a and sql2016.
