SYNTAX

Get-NetTCPConnection [[-LocalAddress] <String[]>] [[-LocalPort] <UInt16[]>] [-RemoteAddress <String[]>]
 [-RemotePort <UInt16[]>] [-State <State[]>] [-AppliedSetting <AppliedSetting[]>] [-OwningProcess <UInt32[]>]
 [-CreationTime <DateTime[]>] [-OffloadState <OffloadState[]>] [-CimSession <CimSession[]>]
 [-ThrottleLimit <Int32>] [-AsJob] [<CommonParameters>]

DESCRIPTION

The Get-NetTCPConnection cmdlet gets current TCP connections. Use this cmdlet to view TCP connection properties such as local or remote IP address, local or remote port, and connection state.

EXAMPLES

Example 1: Get all connections

PS C:\>Get-NetTCPConnection

This command gets all current TCP connections.

Example 2: Get established connections

PS C:\>Get-NetTCPConnection -State Established

This command gets all TCP connections that have an Established state.

Example 3: Get Internet TCP connections

PS C:\>Get-NetTCPConnection -AppliedSetting Internet

This command gets all TCP connections that use a TCP applied setting of Internet.

-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.
