Get-NetAdapterRss

Get-NetAdapterRss

Gets receive side scaling (RSS) properties of the network adapter.

Syntax

Parameter Set: ByName
Get-NetAdapterRss [[-Name] <String[]> ] [-AsJob] [-CimSession <CimSession[]> ] [-IncludeHidden] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Parameter Set: ByInstanceID
Get-NetAdapterRss -InterfaceDescription <String[]> [-AsJob] [-CimSession <CimSession[]> ] [-IncludeHidden] [-ThrottleLimit <Int32> ] [ <CommonParameters>]

Detailed Description

The Get-NetAdapterRss cmdlet gets receive side scaling (RSS) properties of the network adapters that support RSS. RSS is a scalability technology that distributes the receive network traffic among multiple processors by hashing the header of the incoming packet and using an indirection table. Without RSS in Windows Server® 2012 and later, network traffic is received on the first processor which can quickly reach full utilization limiting receive network throughput. Various properties can be configured to optimize the performance of RSS.

Parameters

-AsJob

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-IncludeHidden

Specifies both visible and hidden network adapters should be included. By default only visible network adapters are included. If a wildcard character is used in identifying a network adapter and this parameter has been specified, then the wildcard string is matched against both hidden and visible network adapters.

-InterfaceDescription<String[]>

Specifies the network adapter interface description. For a physical network adapter this is typically the name of the vendor of the network adapter followed by a part number and description, such as Contoso 12345 Gigabit Network Device.

-Name<String[]>

Specifies the name of the network adapter.

-ThrottleLimit<Int32>

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. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

• None

Outputs

The output type is the type of the objects that the cmdlet emits.

• Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetAdapterRssSettingData

  The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.

Examples

EXAMPLE 1

This example gets all of the RSS capable network adapters.

PS C:\> Get-NetAdapterRss –Name *

EXAMPLE 2

This example gets the RSS properties of the network adapter named MyAdapter.

PS C:\> Get-NetAdapterRss –Name MyAdapter

EXAMPLE 3

This example displays all of the RSS properties of the network adapter named MyAdapter.

PS C:\> Get-NetAdapterRss –Name MyAdapter | Format-List -Property *

EXAMPLE 4

This example gets all of the RSS capable network adapters with RSS enabled.

PS C:\> Get-NetAdapterRss –Name * | Where-Object -FilterScript { $_.Enabled }
