Remove-NetQosPolicy -Name SMBRestrictFileCopySpeed Set-SmbBandwidthLimit: Configure SMB Bandwidth Limit with PowerShell To edit or remove a QoS policy, Set-NetQosPolicy and Remove-NetQosPolicy cmdlets are used. To display a list of applied QoS policies on a computer, run this command: New-NetQosPolicy -Name "SMBRestrictFileCopySpeed" -SMB -ThrottleRateActionBitsPerSecond 10MB Name : SMBRestrictFileCopySpeed For example, to create a QoS policy that restrict the bandwidth for SMB (shared file) traffic, use the following command: You can use PowerShell to create and manage network QoS policies. Managing Windows Network QoS Policies via PowerShell The following table shows the levels and their rates.

You can restrict the inbound TCP traffic in the Inbound TCP Traffic tab (the DSCP Marking Override tab refers to DSCP settings, we won’t discuss it here).Īs you can see, there are 4 levels of traffic restriction. In the screenshot below, you can see that the configured QoS policy slow the network file transfer rate on Windows.Īlso, there are Advanced QoS policies available only in the Computer Configuration Group Policy section. Since I have selected all apps and all ports, the policy throttles the maximum network file transfer rate to 3 MB (including file copy using File Explorer - explorer.exe). Note that the Throttle Rate is displayed in kilobytes in the policy editor, even if you have selected MB as its value. You don’t need to reboot your computer, the data transfer rate in the network will be shaped right after you apply the changes. If you want to restrict the access rate to shared files in the SMB folder, select TCP and Port 445.

If you are not sure what protocol your app is using, select TCP and UDP. You can also select a source and a target port.

Then specify a protocol the policy will be applied to (TCP, UDP, or TCP and UDP).

You can also set the destination IP address to restrict the transfer rate for it.

You may need it if you have multiple network adapters or IP aliases

You can specify the IP interface on your computer the policy will be applied to.

exe) or an IIS http(s) site the policy will be applied to.

Then you may select a process/app (an executable file.Don’t use this option if you are unsure of the DSCP QoS settings on your routers. Depending on the DSCP value of a network packet, the routers will set the priority for it. DSCP (Differenciated Services Code Point) may be used on advanced routers like Cisco/Mikrotik.
