Methods

The Msvm_VirtualSwitchManagementService class has these methods.

Method	Description
BindExternalEthernetPort	Binds an external Ethernet port to the Microsoft Windows Virtualization network subsystem. After this call is made, virtual machines can use the external Ethernet port to send data out over the physical network.
ConnectSwitchPort	Connects a switch port to a LAN endpoint. Upon success of the connection, a CIM_ActiveConnection instance will be created that associates the port with the LAN endpoint.
CreateInternalEthernetPort	Creates an internal Ethernet port with a static MAC address.
CreateInternalEthernetPortDynamicMac	Creates an internal Ethernet port with a dynamic MAC address.
CreateSwitch	Creates a new virtual switch.
CreateSwitchPort	Connects a NIC to a virtual switch port.
DeleteInternalEthernetPort	Deletes an internal Ethernet port.
DeleteSwitch	Deletes a virtual switch.
DeleteSwitchPort	Deletes a virtual switch port.
DisconnectSwitchPort	Disconnects a virtual switch port.
RequestStateChange	This method is inherited from CIM_EnabledLogicalElementand is not supported.
SetupSwitch	Sets up a switch such that the existing network architecture is maintained.
StartService	This method is inherited from CIM_Service and is not supported.
StopService	This method is inherited from CIM_Service and is not supported.
TeardownSwitch	Deletes the internal port for a switch and unbinds the external adapter.
UnbindExternalEthernetPort	Unbinds an external Ethernet port to the Microsoft Windows Virtualization network subsystem. After this call is made, virtual machines cannot use the external Ethernet port to send data out over the physical network.

Properties

The Msvm_VirtualSwitchManagementService class has these properties.

Caption

Data type: string
Access type: Read-only
Qualifiers: MaxLen (64)

A short textual description (one-line string) of the object. This property is inherited from CIM_ManagedSystemElement and is always set to "Hyper-V Networking Management Service".

CreationClassName

Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256)

The name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified. This property is inherited from CIM_Service and is always set to "Msvm_VirtualSwitchManagementService".

Description

Data type: string
Access type: Read-only

A textual description of the object. This property is inherited from CIM_ManagedSystemElement and is always set to "Provides Hyper-V Networking WMI management".

ElementName

Data type: string
Access type: Read-only

A textual description of the object. This property is inherited from CIM_ManagedSystemElement and is always set to "Hyper-V Networking Management Service".

EnabledDefault

Data type: uint16
Access type: Read/write

An administrator's default or startup configuration for the enabled state of an element. This property is inherited from CIM_EnabledLogicalElement and is always set to 2 (Enabled).

EnabledState

Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.OtherEnabledState")

The enabled and disabled states of this element. This property is inherited from CIM_EnabledLogicalElement and is always set to 5 (Not Applicable).

Not Applicable (5)

Indicates the element does not support to be enabled or disabled.

HealthState

Data type: uint16
Access type: Read-only

The current health of the element. This property is inherited from CIM_ManagedSystemElement and is always set to 5 (OK).

OK (5)

The element is fully functional and operates within normal operational parameters and without error.

InstallDate

Data type: datetime
Access type: Read-only
Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")

The date and time the object was installed. This property does not need a value to indicate that the object is installed. This property is inherited from CIM_ManagedSystemElement and is not used.

Name

Data type: string
Access type: Read-only
Qualifiers: Key, MaxLen (256)

OperationalStatus

Data type: uint16 array
Access type: Read-only
Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")

The current status of the element. This property is inherited from CIM_ManagedSystemElement and is always set to 2 (OK).

OK (2)

Indicates full functionality without errors.

OtherEnabledState

Data type: string
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")

The enabled or disabled state of the element when the enabled state property is set to 1 ("Other"). This property is inherited from CIM_EnabledLogicalElement and is not used.
