Methods

The MSFT_NetTransportConnection class has these methods.

MethodDescription
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.

OK
5

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

DMTF Reserved
31 ≤ value

DMTF has reserved the unused portion of the continuum for additional HealthStates values in the future.

 

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, Override ("InstanceID")

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.

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.

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.

ValuesMeaning
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

Indicates that an error has occurred.

Non-Recoverable Error
7

A nonrecoverable error has occurred.

Starting
8

The job is starting.

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

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

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.

This property is inherited from CIM_ManagedSystemElement.

The possible values are.
