Methods

The CIM_NetworkPort class has these methods.

Method	Description
EnableDevice	This method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. This method is inherited from CIM_LogicalDevice.
OnlineDevice	This method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. This method is inherited from CIM_LogicalDevice.
QuiesceDevice	This method has been deprecated in lieu of the more general RequestStateChange method that directly overlaps with the functionality provided by this method. This method is inherited from CIM_LogicalDevice.
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.
Reset	Requests a reset of the logical device. This method is inherited from CIM_LogicalDevice.
RestoreProperties	Requests that the Device re-establish its configuration, setup and/or state information from a backing store. This method is inherited from CIM_LogicalDevice.
SaveProperties	Requests that the Device capture its current configuration, setup and/or state information in a backing store. This method is inherited from CIM_LogicalDevice.
SetPowerState	Sets the power state of the Device. The use of this method has been deprecated. Instead, use the SetPowerState method in the associated PowerManagementService class. This method is inherited from CIM_LogicalDevice.

Properties

The CIM_NetworkPort class has these properties.

ActiveMaximumTransmissionUnit

Data type: uint64
Access type: Read-only
Qualifiers: PUnit ("byte"), Units ("Bytes")

AdditionalAvailability

Data type: uint16 array
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_LogicalDevice.Availability")

Additional availability and status of the Device, beyond that specified in the Availability property. The Availability property denotes the primary status and availability of the Device. In some cases, this will not be sufficient to denote the complete status of the Device. In those cases, the AdditionalAvailability property can be used to provide further information. For example, a Device\'s primary Availability may be "Off line" (value=8), but it may also be in a low power state (AdditonalAvailability value=14), or the Device could be running Diagnostics (AdditionalAvailability value=5, "In Test").

This property is inherited from CIM_LogicalDevice.

This property is inherited from CIM_LogicalDevice.

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

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_ManagedElement.

LastErrorCode

Data type: uint32
Access type: Read-only
Qualifiers: Deprecated ("CIM_DeviceErrorData.LastErrorCode")

Captures the last error code reported by the logical device.

This property is inherited from CIM_LogicalDevice.

Infrared (9)
BlueTooth (10)
Wireless LAN (11)

MaxQuiesceTime

Data type: uint64
Access type: Read-only
Qualifiers: Deprecated ("No value"), Units ("MilliSeconds")

This property has been deprecated. When evaluating the use of Quiesce, it was determined that this single property is not adequate for describing when a device will automatically exit a quiescent state. In fact, the most likely scenario for a device to exit a quiescent state was determined to be based on the number of outstanding requests queued rather than on a maximum time. This will be re-evaluated and repositioned later.

Maximum time in milliseconds, that a Device can run in a "Quiesced" state. A Device's state is defined in its Availability and AdditionalAvailability properties, where "Quiesced" is conveyed by the value 21. What occurs at the end of the time limit is device-specific. The Device may unquiesce, may offline or take other action. A value of 0 indicates that a Device can remain quiesced indefinitely.

This property is inherited from CIM_LogicalDevice.

MaxSpeed

Data type: uint64
Access type: Read-only
Qualifiers: PUnit ("bit / second"), Units ("Bits per Second")

The maximum bandwidth of the Port in Bits per Second.

This property is inherited from CIM_LogicalPort.

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.

NetworkAddresses

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

An array of strings that indicates the network addresses for the port.

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.

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.

This property is inherited from CIM_LogicalPort.

PermanentAddress

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

Defines the network address that is hardcoded into a port. This \'hardcoded\' address can be changed using a firmware upgrade or a software configuration. When this change is made, the field should be updated at the same time. PermanentAddress should be left blank if no \'hardcoded\' address exists for the NetworkAdapter.

PortNumber

Data type: uint16
Access type: Read-only

NetworkPorts are often numbered relative to either a logical module or a network element.

PortType

Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_NetworkPort.OtherNetworkPortType")

Defined to force consistent naming of the Type property in subclasses and to guarantee unique enum values for all instances of NetworkPort. When set to 1 ("Other"), related property OtherPortType contains a string description of the type of port. A range of values, DMTF_Reserved, has been defined that allows subclasses to override and define their specific types of ports.

This property is inherited from CIM_LogicalPort.

PowerManagementCapabilities

Data type: uint16 array
Access type: Read-only
Qualifiers: Deprecated ("CIM_PowerManagementCapabilities.PowerCapabilities")

An enumerated array describing the power management capabilities of the Device. The use of this property has been deprecated. Instead, the PowerCapabilites property in an associated PowerManagementCapabilities class should be used.

This property is inherited from CIM_LogicalDevice.

Unknown (0)
Not Supported (1)

PowerManagementSupported

Data type: boolean
Access type: Read-only
Qualifiers: Deprecated ("CIM_PowerManagementCapabilities")

Boolean indicating that the Device can be power managed. The use of this property has been deprecated. Instead, the existence of an associated PowerManagementCapabilities class (associated using the ElementCapabilities relationship) indicates that power management is supported.

This property is inherited from CIM_LogicalDevice.

PowerOnHours

Data type: uint64
Access type: Read-only
Qualifiers: Counter, Units ("Hours")

The number of consecutive hours that this Device has been powered, since its last power cycle.

This property is inherited from CIM_LogicalDevice.

PrimaryStatus

Data type: uint16
Access type: Read-only
Qualifiers: ModelCorrespondence ("CIM_ManagedSystemElement.DetailedStatus", "CIM_ManagedSystemElement.HealthState")

Indicates a high-level status value.

This property is inherited from CIM_ManagedSystemElement.

The possible values are.

RequestedSpeed

Data type: uint64
Access type: Read/write
Qualifiers: ModelCorrespondence ("CIM_LogicalPort.Speed"), PUnit ("bit / second"), Units ("Bits per Second")

The requested bandwidth of the Port in Bits per Second. The actual bandwidth is reported in LogicalPort.Speed.

This property is inherited from CIM_LogicalPort.

RequestedState

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

RequestedState is an integer enumeration that indicates the last requested or desired state for the element. 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. By default, the RequestedState of the element is 5 ("No Change"). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration. It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are "Reboot" (10) and "Reset" (11). Reboot refers to doing a "Shut Down" and then moving to an "Enabled" state. Reset indicates that the element is first "Disabled" and then "Enabled". The distinction between requesting "Shut Down" and "Disabled" should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not execute or accept any commands or processing requests. This property is set as the result of a method invocation (such as StartService or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code. A particular instance of CIM_EnabledLogicalElement might not support RequestStateChange. If this occurs, the value 12 ("Not Applicable") is used.

This property is inherited from CIM_EnabledLogicalElement.

Speed

Data type: uint64
Access type: Read-only
Qualifiers: PUnit ("bit / second"), Override ("Speed"), Units ("Bits per Second")

The current bandwidth of the Port in Bits per Second. For ports that vary in bandwidth or for those where no accurate estimation can be made, this property should contain the nominal bandwidth.

Status

Data type: string
Access type: Read-only
Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

Contains a string indicating the primary status of the object.

Note

This property is deprecated and replaced by the OperationalStatus property. If you choose to use the Status property for backward compatibility it should be secondary to the OperationalStatus property.

This property is inherited from CIM_ManagedSystemElement.

The possible values are.

("OK")
("Error")
("Degraded")
("Unknown")
("Pred Fail")
("Starting")
("Stopping")
("Service")
("Stressed")
("NonRecover")
("No Contact")
("Lost Comm")
("Stopped")

StatusDescriptions

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

Indicates descriptions of the corresponding values in the OperationalStatus array. For example, if an element in the OperationalStatus property contains the value Stopping, then the element at the same array index in this property might contain an explanation as to why an object is being stopped.

This property is inherited from CIM_ManagedSystemElement.

StatusInfo

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

Indicates whether the Logical Device is in an enabled (value = 3), disabled (value = 4) or some other (1) or unknown (2) state. If this property does not apply to the LogicalDevice, the value, 5 ("Not Applicable"), should be used. StatusInfo has been deprecated in lieu of a more clearly named property with additional enumerated values (EnabledState), that is inherited from CIM_ManagedSystemElement.

This property is inherited from CIM_LogicalDevice.

Other (1)
Unknown (2)
Enabled (3)
Disabled (4)
Not Applicable (5)

SupportedMaximumTransmissionUnit

Data type: uint64
Access type: Read-only
Qualifiers: PUnit ("byte"), Units ("Bytes")

The maximum transmission unit (MTU) that can be supported.

SystemCreationClassName

Data type: string
Access type: Read-only
Qualifiers: key, MaxLen (256), Propagated ("CIM_System.CreationClassName")

The scoping System's CreationClassName.

This property is inherited from CIM_LogicalDevice.

SystemName

Data type: string
Access type: Read-only
Qualifiers: key, MaxLen (256), Propagated ("CIM_System.Name")

The scoping System's Name.

This property is inherited from CIM_LogicalDevice.

TimeOfLastStateChange

Data type: datetime
Access type: Read-only

The date or time when the enabled state of the element last changed. If the state of the element has not changed and this property is populated, then it must be set to a 0 interval value. If a state change was requested, but rejected or not yet processed, the property must not be updated.

This property is inherited from CIM_EnabledLogicalElement.

TotalPowerOnHours

Data type: uint64
Access type: Read-only
Qualifiers: Counter, Units ("Hours")

The total number of hours that this Device has been powered.

This property is inherited from CIM_LogicalDevice.

TransitioningToState

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

TransitioningToState indicates the target state to which the instance is transitioning.

A value of 5 "No Change" shall indicate that no transition is in progress.A value of 12 "Not Applicable" shall indicate the implementation does not support representing ongoing transitions.

A value other than 5 or 12 shall identify the state to which the element is in the process of transitioning.

This property is inherited from CIM_EnabledLogicalElement.

UsageRestriction

Data type: uint16
Access type: Read-only

In some circumstances, a LogicalPort might be identifiable as a front end or back end port. An example of this situation would be a storage array that might have back end ports to communicate with disk drives and front end ports to communicate with hosts. If there is no restriction on the use of the port, then the value should be set to 'not restricted'.

This property is inherited from CIM_LogicalPort.

Unknown (0)
Front-end only (2)
Back-end only (3)
Not restricted (4)
