Description

The Set-VMSwitch cmdlet configures a virtual switch.

Examples

Example 1

PS C:\> Set-VMSwitch WA -SwitchType Internal

This example converts a virtual switch named WA to an Internal switch.

Example 2

PS C:\> Set-VMSwitch VMNetwork -NetAdapterName "Ethernet 2"

This example attaches a virtual switch named VMNetwork to a physical ethernet adapter named Ethernet 2. This will also implicitly convert the VMNetwork switch to an external switch.

Example 3

PS C:\> Set-VMSwitch CA -DefaultFlowMinimumBandwidthAbsolute 500000000

This example sets the minimum bandwidth allocation to 500Mbps on a virtual switch named CA for all virtual machines without explicit minimum bandwidth configuration.

Parameters

-AllowManagementOS

Specifies whether the management operating system can use the physical network adapter that is bound to the virtual switch. Setting AllowManagementOS to $true creates management operating system virtual network adapters (VMNetworkAdapters) in the parent partition and connects it to the virtual switch. Setting AllowManagementOS to $false removes any VMNetworkAdapters connected to the virtual switch.

Type:	Boolean
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[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ComputerName

Specifies one or more Hyper-V hosts on which the virtual switch is to be configured. NetBIOS names, IP addresses, and fully qualified domain names are allowable. The default is the local computer. Use localhost or a dot (.) to specify the local computer explicitly.

Type:	String[]
Aliases:	PSComputerName
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Credential

Specifies one or more user accounts that have permission to perform this action. The default is the current user.

Type:	PSCredential[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DefaultFlowMinimumBandwidthAbsolute

Specifies the minimum bandwidth, in bits per second, that is allocated to a special category called "default flow." Any traffic sent by a virtual network adapter that is connected to this virtual switch and does not have minimum bandwidth allocated is filtered into this category. Specify a value for this parameter only if the minimum bandwidth mode on this virtual switch is absolute (See the New-VMSwitch cmdlet). By default, the virtual switch allocates 10% of the total bandwidth, which depends on the physical network adapter it binds to, to this category. For example, if a virtual switch binds to a 1 GbE network adapter, this special category can use at least 100 Mbps. If the value is not a multiple of 8, the value is rounded down to the nearest number that is a multiple of 8. For example, a value input as 1234567 is converted to 1234560.

Type:	Int64
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DefaultFlowMinimumBandwidthWeight

Specifies the minimum bandwidth, in relative weight, that is allocated to a special category called "default flow". Any traffic sent by a virtual network adapter that is connected to this virtual switch and doesn't have minimum bandwidth allocated is filtered into this category. Specify a value for this parameter only if the minimum bandwidth mode on this virtual switch is weight (See the New-VMSwitch cmdlet). By default, this special category has a weight of 1.

Type:	Int64
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DefaultQueueVmmqEnabled

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DefaultQueueVmmqQueuePairs

Type:	UInt32
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DefaultQueueVrssEnabled

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Extensions

Specifies an ordered list of network extensions used to reorder the bindings on the virtual switch.

Type:	VMSwitchExtension[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Name

Specifies the name of the virtual switch to be configured.

Type:	String[]
Aliases:	SwitchName
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-NetAdapterInterfaceDescription

Specifies the interface description of the physical network adapter to which an external virtual switch should be bound. If you specify this parameter to convert a virtual switch, the external virtual switch is configured to allow the management operating system to share access to the physical network adapter. To override this behavior, include AllowManagementOs $false in the command

Type:	String
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-NetAdapterName

Specifies the name of the physical network adapter to which an external virtual switch should be bound. If you specify this parameter to convert a virtual switch, the external virtual switch is configured to allow the management operating system to share access to the physical network adapter. To override this behavior, include AllowManagementOs $false in the command

Type:	String
Aliases:	InterfaceAlias
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Notes

Specifies notes to be associated with the virtual switch.

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Passthru

Specifies that a Microsoft.HyperV.PowerShell.EthernetSwitch object is to be passed through to the pipeline representing the virtual switch to be configured.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-SwitchType

Converts a virtual switch from one type to another. Allowed values are Internal or Private. You can convert an internal or private virtual switch to an external virtual switch, by including either the NetAdapterInterfaceDescription or NetAdapterName parameter in the command. If you do this, the external virtual switch is configured to allow the management operating system to share access to the physical network adapter. To override this behavior, include AllowManagementOs $false in the command.

Type:	VMSwitchType
Accepted values:	Private, Internal, External
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-VMSwitch

Specifies the virtual switch to be configured.

Type:	VMSwitch[]
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
