NAME
Get-NetAdapterRsc
SYNOPSIS
Gets network adapters that support RSC.
SYNTAX
Get-NetAdapterRsc [[-Name] ] [-AsJob] [-CimSession ] [-IncludeHidden] [-IPv4FailureReason
] [-IPv4OperationalState ] [-IPv6FailureReason ]
[-IPv6OperationalState ] [-ThrottleLimit ] []
Get-NetAdapterRsc [-AsJob] [-CimSession ] [-IncludeHidden] [-IPv4FailureReason ]
[-IPv4OperationalState ] [-IPv6FailureReason ] [-IPv6OperationalState ]
[-ThrottleLimit ] -InterfaceDescription []
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.
PARAMETERS
-AsJob []
ps_cimcommon_asjob
Required? false
Position? named
Default value
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.
Required? false
Position? named
Default value
Accept pipeline input? false
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.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-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.
Required? true
Position? named
Default value
Accept pipeline input? true (ByPropertyName)
Accept wildcard characters? true
-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
Required? false
Position? named
Default value
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.
Required? false
Position? named
Default value
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.
Required? false
Position? named
Default value
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.
Required? false
Position? named
Default value
Accept pipeline input? true (ByPropertyName)
Accept wildcard characters? false
-Name
Specifies an array of network adapter names.
Required? false
Position? 1
Default value
Accept pipeline input? true (ByPropertyName)
Accept wildcard characters? true
-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 PowerShellr 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.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see

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.
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.
