Detaillierte Beschreibung

The Get-NetTCPSetting cmdlet gets TCP settings. TCP settings are optimized for different network conditions including latency and congestion. To apply a TCP setting to a port number or destination IP address range, create a transport filter by using the New-NetTransportFilter cmdlet.

Specify a setting to get by using the SettingName parameter, or by specifying a transport filter that is associated with a setting. Specify parameter values to determine which settings to get, or do not include any parameters to get all TCP settings.

Parameter

-AssociatedTransportFilter<CimInstance>

Specifies CIM object for a transport filter associated with a setting. The cmdlet gets the setting for this transport filter. To obtain a transport filter, use the Get-NetTransportFilter cmdlet.
