Description

The New-NetQosPolicy cmdlet creates a new network Quality of Service (QoS) policy. A QoS policy consists of two main parts: match conditions also known as filters, and actions. Match conditions such as the name by which an application is run in Windows Server® 2012 and later or a TCP port number decide to what traffic the policy is relating. Parameters such as DSCPAction and ThrottleRateAction determine how the policy is to handle the matched traffic. Besides match conditions and actions, there are also some general parameters such as NetworkProfile and Precedence that the users can customize for a QoS policy.

A list of well-known match conditions, or filters, in the form of parameters is provided: FCoE, Cluster (3343), LiveMigration (6600), iSCSI (3260), NFS (2049), and SMB (445). Each of them matches a well-known TCP port specified in the brackets. The only exception is FCoE, which matches EtherType 0x8906. These filters must be used alone for filtering purpose. In other words, they cannot be mixed with other match condition parameters.

QoS policies can be stored in multiple locations. Users can choose a location by specifying the PolicyStore parameter. If the PolicyStore parameter is not specified, then the new policy is added to local computer (localhost). If a policy is stored in ActiveStore, then the policy will not persist after reboot.

Examples

Example 1: Create a QoS policy

PS C:\> New-NetQosPolicy -Name "SMB Policy" -SMB -PriorityValue8021Action 3
Name           : SMB Policy 
Owner          : Group Policy (Machine) 
NetworkProfile : All 
Precedence     : 127 
Template       : SMB 
PriorityValue  : 3

This command creates a QoS policy named SMB Policy that classifies SMB traffic and tags it with 802.1p priority value of 3. The SMB parameter is a built-in filter that matches TCP port 445, which is reserved for SMB.

Example 2: Create a QoS policy that matches an application

PS C:\> New-NetQosPolicy -Name "FTP" -AppPathNameMatchCondition "ftp.exe" -ThrottleRateActionBitsPerSecond 1MB -PolicyStore ActiveStore
Name           : FTP 
Owner          : PowerShell / WMI 
NetworkProfile : All 
Precedence     : 127 
AppPathName    : ftp.exe 
ThrottleRate   : 1.049 MBits/sec

This command creates a QoS policy named FTP that matches an application path at ftp.exe and throttles the traffic at 8,000,000 bits per second. This policy is ActiveStore. This means that it is not persistent after restart of the computer.

Example 3: Create a QoS policy that matches traffic to a subnet

PS C:\> New-NetQosPolicy -Name "Backup" -IPDstPrefixMatchCondition "10.1.1.176/28" -NetworkProfile Domain -DSCPAction 40
Name           : Backup 
Owner          : Group Policy (Machine) 
NetworkProfile : Domain 
Precedence     : 127 
IPProtocol     : Both 
IPDstPrefix    : 10.1.1.176/28 
DSCPValue      : 40

This command creates a QoS policy named Backup that matches traffic sent to 10.1.1.176/28 subnet and tags it with DSCP value of 40. This policy is effective only on traffic sent on a domain-joined network adapter.

Example 4: Create a QoS policy that matches traffic sent to a port

PS C:\> New-NetQosPolicy -Name "HTTP" -IPPort 80 -IPProtocol TCP -ThrottleRateActionBitsPerSecond 10MB
Name           : HTTP 
Owner          : Group Policy (Machine) 
NetworkProfile : All 
Precedence     : 127 
IPProtocol     : TCP 
IPPort         : 80 
ThrottleRate   : 10.486 MBits/sec

This command creates a QoS policy that matches TCP traffic sent to port 80 and rate-limits it at 80,000,000 bits per second.

Example 5: Create a default QoS policy

PS C:\> New-NetQosPolicy -Name "Wildcard" -Default -MinBandwidthWeightAction 30
Name               : wildcard 
Owner              : Group Policy (Machine) 
NetworkProfile     : All 
Precedence         : 127 
Template           : Default 
MinBandwidthWeight : 30

This command creates a QoS policy named Wildcard that catches all the traffic that does not match a specific QoS policy and assigns a minimum bandwidth weight of 30 to such traffic.

Example 6: Create a QoS policy that matches return traffic from an application

PS C:\> New-NetQosPolicy -Name "IIS" -URIMatchCondition "http://training" -ThrottleRateActionBitsPerSecond 500KB
Name           : IIS 
Owner          : Group Policy (Machine) 
NetworkProfile : Domain 
Precedence     : 127 
URI            : http://training/ 
URIRecursive   : False 
ThrottleRate   : 516.096 KBits/sec

This command creates a QoS policy named IIS that matches return traffic from an HTTP server application with the specified URI and rate limit the return traffic at 4,000,000 bits per second.

Specifies a wildcard filter that can be used to capture all traffic that is not matched by any other filter. One use case is that a user can create a QoS policy for a specific application using the AppPathNameMatchCondition parameter and create another QoS policy for all other applications using this parameter. Another use case is that a user can create several QoS policies, each of which specifies a minimum bandwidth action for the filtered traffic, and create one additional policy using this parameter to assign a minimum bandwidth action for all other traffic.

If either the source port or the destination port in a packet matches the value of this parameter, then the QoS policy will apply to the packet. Usually this is a well-known port that a client uses to communicate with a server. With this parameter specified, the same QoS policy can be configured on both the clients and the servers and apply to the traffic in both directions. For example, specifying the IPPortMatchCondition parameter value of 80 matches HTTP traffic sent by both HTTP clients and HTTP servers.
