CIM_DeviceConnection class (Hyper-V management)

A relationship that indicates that two or more devices are connected together.

Syntax

[Association, Abstract, Version("2.10.0"), UMLPackagePath("CIM::Device::DeviceElements"), AMENDMENT]
class CIM_DeviceConnection : CIM_Dependency
{
  CIM_LogicalDevice REF Antecedent;
  CIM_LogicalDevice REF Dependent;
  uint64                NegotiatedSpeed;
  uint32                NegotiatedDataWidth;

Properties

The CIM_DeviceConnection class has these properties.

Antecedent

Data type: CIM_LogicalDevice

Access type: Read-only

Qualifiers: Override ("Antecedent")

A device.

Dependent

Data type: CIM_LogicalDevice

Access type: Read-only

Qualifiers: Override ("Dependent")

A second device that is connected to the other device.

NegotiatedDataWidth

Data type: uint32

Access type: Read-only

Qualifiers: Units ("Bits"), MappingStrings ("MIF.DMTF|Bus Port Association|001.3"), PUnit ("bit")

When several bus and connection data widths are possible, the NegotiatedDataWidth property defines the one that is in use between the Devices. Data width is specified in bits. If data width is not negotiated, or if this information is not available or not important to Device management, the property should be set to 0.

NegotiatedSpeed

Data type: uint64

Access type: Read-only

Qualifiers: Units ("Bits per Second"), MappingStrings ("MIF.DMTF|Bus Port Association|001.2"), PUnit ("bit / second")

When several bus and connection speeds are possible, this property defines the speed that is in use between the devices, in bits per second. If connection or bus speeds are not negotiated, or if this information is not available, or not important to device management, the property should be set to "0".
