CIM_LogicalPort class

The abstraction of a port or connection point of a device. This object should be instantiated when the port has independent management characteristics from the device that includes it. Examples are a Fibre Channel Port and a USB Port.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Properties

The CIM_LogicalPort class has these properties.

AdditionalAvailability

Data type: unit16

Access type: Write-only

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).

DeviceID

Data type: string

Access type: Read-only

Address or other identifying information to uniquely name the logical device. This property inherits from CIM_LogicalDevice.

ElementName

Data type: string

Access type: Read-only

A user-friendly name for the object. This property enables each instance to define a display name in addition to its key properties, identity data, and description information. Be aware that the Name property of ManagedSystemElement is also defined as a display name. However, it is often subclassed to be a Key. The same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. This property inherits from CIM_ManagedElement.

ErrorCleared

Qualifiers: Depricated

Free-form string that supplies information about the error recorded in the LastErrorCode property and corrective actions to perform. This property inherits from CIM_LogicalDevice.

HealthState

Data type: uint16

Access type: Write-only

Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its subcomponents. The possible values are 0 to 30, where 5 means the element is entirely healthy and 30 means the element is completely. This property inherits from CIM_ManagedSystemElement.

Unknown 0

The implementation cannot report on HealthState at this time.

OK 5

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

Degraded/Warning 10

The element is in working order 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.

Minor Failure 15

All functionality is available but some might be degraded.

Major Failure 20

The element is failing. It is possible that some or all of the functionality of this component is degraded or not working.

Critical Failure 25

The element is non-functional and recovery might not be possible.

Non-recoverable Error 30

The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost.

Reserved ...

The remaining values are reserved for DTMF use.

 

IdentifyingDescriptions

Data type: string array

Access type: Read-only

An array of free-form strings providing explanations and details behind the entries in the OtherIdentifyingInfo array. Note, each entry of this array is related to the entry in OtherIdentifyingInfo that is located at the same index. This property inherits from CIM_LogicalDevice.

InstallDate

Data type: datetime

Access type: Read-only

Indicates when the object was installed. Lack of a value does not indicate that the object is not installed. This property inherits from CIM_ManagedSystemElement.

InstanceId

Data type: string

Access type: Read-only

Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: OrgID:LocalID Where OrgID and LocalID are separated by a colon (:), and where OrgID must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the SchemaName_ClassName structure of Schema class names.) In addition, to ensure uniqueness, OrgID must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between OrgID and LocalID. LocalID is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If the above preferred algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. For DMTF-defined instances, the "preferred" algorithm must be used with the OrgID set to CIM. This property inherits from CIM_ManagedElement.

LastErrorCode

Data type: uint32

Access type: Read-only

Qualifiers: Depricated

Last error code reported by the logical device. This property inherits from CIM_LogicalDevice.

MaxQuiesceTime

Data type: uint64

Access type: Read-only

Qualifiers: Depricated

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.

Note  

"The MaxQuiesceTime property has been deprecated. When evaluating the use of Quiesce, it was determine 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.

This property inherits from CIM_LogicalDevice.

MaxSpeed

Data type: uint64

Access type: Read-only

Qualifiers: Units ( "Bits per Second" )

The maximum bandwidth, in bits per second, of the port.

Name

Data type: string

Access type: Read-only

Label by which the object is known. When subclassed, this property can be overridden to be a key property. This property inherits from CIM_ManagedSystemElement.

OperatingStatus

Data type: uint16

Access type: Read-only

Provides a current status value for the operational condition of the element and can be used for providing more detail with respect to the value of EnabledState. It can also provide the transitional states when an element is transitioning from one state to another, such as when an element is transitioning between EnabledState and RequestedState, as well as other transitional conditions. This property inherits from CIM_ManagedSystemElement.

Value Meaning
Unknown 0

the implementation is in general capable of returning this property, but is unable to do so at this time.

Not Available 1

the implementation (provider) is capable of returning a value for this property, but not ever for this particular piece of hardware/software or the property is intentionally not used because it adds no meaningful information (as in the case of a property that is intended to add additional info to another property).

Servicing 2

describes an element being configured, maintained, cleaned, or otherwise administered. Starting describes an element being initialized. \n\"Stopping\" describes an element being brought to an orderly stop.

Starting 3

The element is starting.

Stopping 4

The element is stopping.

Stopped 5

A a clean and orderly stop has occurred.

Aborted 6

An abrupt stop has occurred; the state and configuration of the element might need to be updated.

Dormant 7

The element is inactive or quiesced.

Completed 8

The element has completed its operation. This value should be combined with either OK, Error, or Degraded in the PrimaryStatus 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).

Migrating 9

The element is being moved between host elements.

Emigrating 10

The element is being moved away from host element.

Immigrating 11

The element is being moved to new host element.

Snapshotting 12
Shutting Down 13

The element being brought to an abrupt stop.

In Test 14

The element is performing test functions.

Transitioning 15

The element is between states, that is, it is not fully available in either its previous state or its next state. This value should be used if other values indicating a transition to a specific state are not applicable.

In Service 16

The element is in service and operational."

OperationalStatus

Data type: uint16

Access type: Write-only

The current statuses of the element. This property inherits from CIM_ManagedSystemElement.

Value Meaning
Unknown 0

An unknown error has occured.

Other 1

An error other than one on this list has occured.

OK 2

The elemetn is OK.

Degraded 3

The element has been degraded.

Stressed 4

The element is functioning, but needs attention. Examples of Stressed states are overload, overheated, and so on.

Predictive Failure 5

An element is functioning nominally but predicting a failure in the near future.

Error 6

An error has occurred.

Non-Recoverable Error 7

A non-recoverable error has occurred.

Starting 8

The element is in the process of starting.

Stopping 9

The element is in the process of stopping.

Stopped 10

A clean and orderly stop has occurred.

In Service 11

An element being configured, maintained, cleaned, or otherwise administered.

No Contact 12

The monitoring system has knowledge of this element, but has never been able to establish communications with it.

Lost Communication 13

The Managed System Element is known to exist and has been contacted successfully in the past, but is currently unreachable.

Aborted 14

An abrupt stop has occurred; the state and configuration of the element might need to be updated.

Dormant 15

The element is inactive or quiesced.

Supporting Entity in Error 16

The current element might be OK, but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower-layer networking problems.

Completed 17

the element has completed its operation. This value should be combined with either OK, Error, 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

The element has additional power model information contained in the Associated PowerManagementService association.

Relocating 19

indicates the element is being relocated. OperationalStatus replaces the Status property on ManagedSystemElement to provide a consistent approach to enumerations, to address implementation needs for an array property, and to provide a migration path from today\'s environment to the future. This change was not made earlier because it required the deprecated qualifier. Due to the widespread use of the existing Status property in management applications, it is strongly recommended that providers or instrumentation provide both the Status and OperationalStatus properties. Further, the first value of OperationalStatus should contain the primary status for the element. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.
