Access type: Read-only

Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_EthernetPort.Capabilities")

An array of free-form strings that provides more detailed explanations for any of the EthernetPort features that are indicated in the Capabilities array. Note, each entry of this array is related to the entry in the Capabilities array that is located at the same index. This property is inherited from CIM_EthernetPort.

Caption

PowerManagementCapabilities

Data type: uint16 array

Access type: Read-only

Qualifiers: Deprecated ("CIM_PowerManagementCapabilities.PowerCapabilities")

An array of the specific power-related capabilities of a logical device. This property is inherited from CIM_LogicalDevice.

PowerManagementSupported

Data type: boolean

Access type: Read-only

Qualifiers: Deprecated ("CIM_PowerManagementCapabilities")

If TRUE, the device can be power managed, that is, put into a power-save state. If FALSE, the integer value 1 (Not Supported) should be the only entry in the PowerManagementCapabilities property array.

This property does not indicate whether power management features are currently enabled, or if enabled, which features are supported. For more information, see the PowerManagementCapabilities property array.

PowerOnHours

Data type: uint64

Access type: Read-only

Qualifiers: Deprecated ("CIM_PoweredStatisticalData.PowerOnHours"), Units ("Hours"), Counter

This property is inherited from CIM_LogicalDevice but it is not used.

RequestedSpeed

Data type: uint64

Access type: Read/write

Qualifiers: Units ("Bits per Second"), ModelCorrespondence ("CIM_LogicalPort.Speed")

The requested bandwidth of the port in bits per second. The actual bandwidth is reported in the Speed property. This property is inherited from CIM_LogicalPort.

RequestedState

Data type: uint16

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_EnabledLogicalElement.EnabledState")

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 10 (Reboot) and 11 (Reset). 10 (Reboot) refers to doing a 4 (Shut Down) and then moving to an 2 (Enabled) state. Reset indicates whether the element is first 3 (Disabled) and then 2 (Enabled). The distinction between requesting 4 (Shut Down) and 3 (Disabled) should also be noted. 4 (Shut Down) requests an orderly transition to the 3 (Disabled) state, and might involve removing power, to completely erase any existing state. The 3 (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 Start 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 an enabled logical element might not support RequestedStateChange. If this occurs, the value 12 (Not Applicable) is used.

Data type: uint64

Access type: Read-only

Qualifiers: Deprecated ("CIM_PoweredStatisticalData.TotalPowerOnHours"), Units ("Hours"), Counter

UsageRestriction

Data type: uint16

Access type: Read-only

In some circumstances, a logical port 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.

The possible values are.
