Methods

The MSFT_NetTransportConnection class has these methods.

Method	Description
RequestStateChange	Requests that the state of the element be changed to the value specified in the RequestedState parameter. When the requested state change takes place, the enabled state and requested state of the element will be the same. Invoking the RequestChangeState method multiple times could result in earlier requests being overwritten or lost. If 0 is returned, then the task completed successfully and the use of CIM_ConcreteJob was not required. If 4096 (0x1000) is returned, then the task will take some time to complete, CIM_ConcreteJob will be created, and its reference returned in the output parameter Job. Any other return code indicates an error condition. This method is inherited from CIM_EnabledLogicalElement.

InstallDate

Data type: datetime
Access type: Read-only

Indicates when the object was installed. The lack of a value does not indicate that the object is not installed.

This property is inherited from CIM_ManagedSystemElement.

InstanceID

Data type: string
Access type: Read-only
Qualifiers: key

Uniquely and opaquely identifies an instance of this class within the scope of the containing Namespace.

[!Important]In order to ensure uniqueness within the Namespace, the value of InstanceID should be constructed in the following pattern:

OrgID:LocalID

OrgID must include a copyrighted, trademarked or otherwise unique name that is owned by the business entity defining the InstanceID, or be a registered ID that is assigned by a recognized global authority. This is similar to the structure of Schema class names. In addition, to ensure uniqueness the first colon in InstanceID must be between the OrgID andLocalID. Therefor the OrgID must not contain a colon (':').

LocalID is chosen by the business entity and should not be re-used to identify different underlying real-world elements.

If the preceding pattern is not used, the defining entity must assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this Namespace.

For Distributed Management Task Force (DMTF) defined instances, the pattern must be used with the OrgID set to CIM.

This property is inherited from CIM_NetworkPipe.

LocalAddress

Data type: string
Access type: Read-only

The local address of the transport connection.

LocalPort

Data type: uint16
Access type: Read-only

The local port of the transport connection.

Name

Data type: string
Access type: Read-only
Qualifiers: MaxLen (1024)

Indicates the user-friendly name for this instance of a job. In addition, the user-friendly name can be used as a property for a search or query.

[!Tip]
Name does not have to be unique within a namespace.

This property is inherited from CIM_ManagedSystemElement.

OperatingStatus

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

Indicates the current operational condition of the element. This property can be used to provide more detail about the current state of the element. It can also indicate transitional states. A NULL value indicates that the instrumentation does not support this property.

This property is inherited from CIM_ManagedSystemElement.

Value	Meaning
Unknown 0	Indicates that the instrumentation cannot report on the OperatingStatus property at this time.
Not Available 1	Indicates that the instrumentation is capable of reporting this property, but intentionally does not report it for this element.
Servicing 2	Indicates that the element is in process to be configured, maintained, cleaned, or otherwise administered.
Starting 3	Indicates that the element is being initialized.
Stopping 4	Indicates that the element is being brought to an orderly stop.
Stopped 5	Indicates that the element is intentionally stopped.
Aborted 6	Indicates that the element stopped in an unexpected way.
Dormant 7	Indicates that the element is inactive or quiesced.
Completed 8	Indicates that the element completed its operation. We recommend using a PrimaryStatus property value of OK, Error, or Degraded to indicate success or failure of the operation.
Migrating 9	Indicates that the element is being moved between host elements.
Emigrating 10	Indicates that the element is being moved away from the host element.
Immigrating 11	Indicates that the element is being moved to a new host element.

In Service 16	Indicates that the element is in service and operational.
DMTF Reserved 17 32767	Reserved.
Vendor Reserved 32768 = value	Reserved.

OperationalStatus

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

Contains indicators of the current status of the element. The first value of OperationalStatus should contain the primary status for the element.

Note

OperationalStatus replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, Microsoft strongly recommends that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.

This property is inherited from CIM_ManagedSystemElement.

Values	Meaning
Unknown 0	Indicates the implementation cannot report on OperationalStatus at this time.
Other 1	Indicates an undefined state.
OK 2	Indicates full functionality without errors.
Degraded 3	Indicates the element is working and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors
Stressed 4	Indicates that the element is functioning, but needs attention. Overload and overheated are examples of Stressed states.
Predictive Failure 5	Indicates that an element is functioning nominally but predicting a failure in the near future.
Error 6	Indicates that an error has occurred.
Non-Recoverable Error 7	A nonrecoverable error has occurred.
Starting 8	The job is starting.
Stopping 9	The job is stopping.
Stopped 10	The element has been intentionally stopped.
In Service 11	Indicates the element is being configured, maintained, cleaned, or otherwise administered.
No Contact 12	Indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.
Lost Communication 13	Indicates that the job is known to exist and has been contacted successfully in the past, but is currently unreachable.
Aborted 14	Indicates the job stopped in an unexpected way. The state and configuration of the job might need to be updated.
Dormant 15	Indicates that the job is inactive.
Supporting Entity in Error 16	Indicates that an element on which this job depends is in error. This element may be OK but is unable to function because of the state of a dependent element. An example is a network service or endpoint that cannot function due to lower-layer networking problems.
Completed 17	Indicates that the job has completed its operation. This value should be combined with either OK, ErrorError, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error).
Power Mode 18	"Power Mode" indicates that the element has additional power model information contained in the associated PowerManagementService association.
DMTF Reserved 19 32767	DMTF has reserved this portion of the range for additional OperationalStatus values in the future.
Vendor Reserved 32768 65535	Microsoft has reserved the unused portion of the range for additional OperationalStatus values in the future.

RequestedState

Data type: uint16
Access type: Read/write
Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")

RequestedState is an integer enumeration that indicates the last requested or desired state for the element, irrespective of the mechanism through which it was requested. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. Note that when EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration.

This property is inherited from CIM_NetworkPipe.

Enabled 2
Disabled 3	requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests.
Shut Down 4	Requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state.
No Change 5	Deprecated in lieu of indicating the last requested state is "Unknown" (0). If the last requested or desired state is unknown, RequestedState should have the value "Unknown" (0), but may have the value "No Change" (5).
Offline 6	The element has been requested to transition to the Enabled but Offline EnabledState.
Test 7
Deferred 8
Quiesce 9
Reboot 10	Refers to doing a "Shut Down" and then moving to an "Enabled" state.
