NAME Set-SmbBandwidthLimit



SYNOPSIS

Adds an SMB bandwidth cap.





SYNTAX

Set-SmbBandwidthLimit [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] -BytesPerSecond <UInt64> -Category {Default | VirtualMachine |

LiveMigration} [-Confirm] [-WhatIf] [<CommonParameters>]





DESCRIPTION

The Set-SmbBandwidthLimit cmdlet adds a Server Message Block (SMB) bandwidth cap for the traffic categories that you specify. SMB bandwidth caps limit

the amount of data that the server can send for each traffic category.





PARAMETERS

-BytesPerSecond <UInt64>

Specifies the maximum number of bytes per second that the server can send for the traffic categories that you specify. You can specify units after

the number of bytes, such as KB, MB, and GB. You cannot specify a value smaller than 1MB (1048576 bytes) for this parameter.



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Category <BandwidthLimitCategory>

Specifies an array of categories of the SMB bandwidth limits to add. The acceptable values for this parameter are:



-- Default

-- VirtualMachine

-- LiveMigration



Required? true

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-CimSession [<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 none

Accept pipeline input? false

Accept wildcard characters? false



-ThrottleLimit [<Int32>]

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.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Confirm [<SwitchParameter>]

Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the cmdlet.

NOTES





Before you can use this cmdlet, you must enable the feature by using the following command:

Add-WindowsFeature -Name FS-SMBBW

For more information, type Get-Help Install-WindowsFeature. When you enable the feature, the SMB server creates a new SMB performance counter set

that has an instance per category. The performance counters in this set use the same counters as the SMB Client Shares performance counters.



Example 1: Add an SMB limit



PS C:\\> Set-SmbBandwidthLimit -Category Default -BytesPerSecond 100MB



This command limits SMB traffic to 100 megabytes per second for traffic that is unrelated to Hyper-V over SMB or Live Migration.





Example 2: Add an SMB limit for live migration



PS C:\\> Set-SmbBandwidthLimit -Category LiveMigration -BytesPerSecond 1GB



This command limits SMB traffic to 1 gigabyte per second for Live Migration.
