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.

Data type: string
Access type: Read-only

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

InstallDate
Data type: datetime

Last error code reported by the logical device.

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

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.

The device can change its power state based on usage or other criteria.

5 (0x5)

Power State Settable

The SetPowerState method is supported. This method is found on the parent CIM_LogicalDevice class and can be implemented. For more information, see Designing Managed Object Format (MOF) Classes.

In some cases, 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'.
