Description

The Get-SmbMultichannelConnection cmdlet retrieves the Server Message Block (SMB) connections made between the SMB client network interfaces and the SMB server network interfaces. This cmdlet provides information about how the SMB multi-channel pairs the client and the server network interfaces and which pairs are selected to use for the SMB connections.

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

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

Indicates the client and server network interface combinations which are not selected are used by SMB are also enumerated.

-ServerName

Specifies that the multi-channel connections made to the given server are enumerated.

Type: String[]
Position: 1

Accept wildcard characters: False
-SmbInstance

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

Type: SmbInstance
Parameter Sets: Default, CSV, SBL, SR
Position: Named
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.

None

Outputs

Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/SMB/MSFT_SmbMultiChannelConnection

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. The MSFT_SmbMultiChannelConnection object represents a pair of a client and a server network interface.
