Description

The Get-NetAdapterRsc cmdlet gets network adapters that support receive segment coalescing (RSC). RSC takes multiple packets received within the same interrupt period and combines the packets into a single large package to be processed by the network stack. This reduces the processing overhead for incoming packets and reduces the number of processor cycles that are used, leading to better scalability.

Examples

Example 1: Get the RSC properties for the specified network adapter 

PS C:\> Get-NetAdapterRsc -Name "MyAdapter"

This command gets the RSC properties of the network adapter named MyAdapter.

Example 2: Get all RSC capable network adapters 

PS C:\> Get-NetAdapterRsc -Name "*"

This command gets all of the RSC capable network adapters.

Example 3: Get all RSC capable network adapters that have RSC enabled 

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

This command gets all of the RSC capable network adapters that have RSC enabled.

Required Parameters

-InterfaceDescription

Specifies an array of network adapter interface descriptions. 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 .

Type: String[]
Aliases: ifDesc, InstanceID
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

Optional Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs .

Type: SwitchParameter
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-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.

Type: CimSession[]
Aliases: Session
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-IPv4FailureReason

Specifies the reason that RSC may not be working on IPv4 traffic.

The acceptable values for this parameter are:

  • NoFailure
  • NicPropertyDisabled
  • WFPCompatibility
  • NDISCompatibility
  • ForwardingEnabled
  • NetOffloadGlobalDisabled
Type: FailureReason[]
Parameter Sets: NoFailure, NicPropertyDisabled, WFPCompatibility, NDISCompatibility, ForwardingEnabled, NetOffloadGlobalDisabled, Capability, Unknown
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-IPv4OperationalState

Specifies the state of the TCP/IP protocol driver for RSC. See the IPv4FailureReason parameter value for more information.

Type: Boolean[]
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-IPv6FailureReason

Returns the reason that of RSC may not be working on IPv6 traffic.

The acceptable values for this parameter are:

  • NoFailure
  • NicPropertyDisabled
  • WFPCompatibility
  • NDISCompatibility
  • ForwardingEnabled
  • NetOffloadGlobalDisabled

If RSC is desired, then the following actions can be taken:

  • NicPropertyDisabled: Run the Enable-NetAdapterRsc cmdlet to enable RSC on the specified network adapter.
  • WFPCompatibility: Disable the WFP filters.
  • NDISCompatibility: Upgrade to an NDIS 6.30 driver.
  • ForwardingEnabled: Disable forwarding.
  • NetOffloadGlobalDisabled: Run the Set-NetOffloadGlobalSetting cmdlet with the ReceiveSegmentCoalescing parameter set to Enabled.
Type: FailureReason[]
Parameter Sets: NoFailure, NicPropertyDisabled, WFPCompatibility, NDISCompatibility, ForwardingEnabled, NetOffloadGlobalDisabled, Capability, Unknown
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-IPv6OperationalState

Specifies the state of the TCP/IP protocol driver for RSC. See the IPv6FailureReason parameter value for more information.

Type: Boolean[]
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-IncludeHidden

Indicates that the cmdlet includes both visible and hidden network adapters in the operation. 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.

Type: SwitchParameter
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Name

Specifies an array of network adapter names.

Type: String[]
Aliases: ifAlias, InterfaceAlias
Position: 0
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-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. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type: Int32
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

Inputs

None

Outputs

Microsoft.Management.Infrastructure.CimInstance#ROOT/StandardCimv2/MSFT_NetAdapterRscSettingData

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.
