[<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.

Parameters
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| 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 |
| Required: | False |
| 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.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ServerName
Specifies that the multi-channel connections made to the given server are enumerated.
| Type: | String[] |
| Position: | 1 |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |

Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
| Type: | SmbInstance |
| Accepted values: | Default, CSV, SBL, SR |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | True |
| 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.

Outputs
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.
