function Get-DbaTcpPort { <# .SYNOPSIS Returns the TCP port used by the specified SQL Server. .DESCRIPTION By default, this command returns just the TCP port used by the specified SQL Server. If -Detailed is specified, server name, IPAddress (ipv4 and ipv6), port number and if the port assignment is static. .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER Credential Credential object used to connect to the SQL Server as a different user .PARAMETER Detailed Returns an object with server name, IPAddress (ipv4 and ipv6), port and static ($true/$false) for one or more SQL Servers. 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 ExcludeIpv6 Excludes IPv6 information when -Detailed is specified. .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Tags: SQLWMI, tcp Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Get-DbaTcpPort .EXAMPLE Get-DbaTcpPort -SqlInstance sqlserver2014a Returns just the port number for the default instance on sqlserver2014a .EXAMPLE 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 Get-DbaTcpPort -SqlInstance sqlserver2014a, sql2016 -Detailed Returns an object with server name, IPAddress (ipv4 and ipv6), port and static ($true/$false) for sqlserver2014a and sql2016 Remote sqlwmi is used by default.
