Brian Lich|Last Updated: 4/3/2017

SYNOPSIS

Retrieves the SMB connections made between the SMB client network interfaces and the SMB server network interfaces.

SYNTAX

Get-SmbMultichannelConnection [[-ServerName] <String[]>] [-IncludeNotSelected] [-SmbInstance <SmbInstance>]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [<CommonParameters>]

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.

EXAMPLES

Example 1: Get connections

PS C:\>Get-SmbMulitchannelConnection
Server Name    Selected       Client IP      Server IP      Client         Server         Client RSS     Client RDMA

-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.

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.
