Msvm_ActiveConnection class

Article
01/07/2021

Connects a switch port to the LAN endpoint to which the port is connected. The existence of this object means that the switch port and the LAN endpoint are actively connected and the Ethernet port associated with the LAN endpoint can communicate with the network through the switch port.

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

Syntax

[Association, Dynamic, Provider("VmmsWmiInstanceAndMethodProvider"), AMENDMENT]
class Msvm_ActiveConnection : CIM_ActiveConnection
{
  Msvm_LANEndpoint REF Antecedent;

Properties

Properties

The Msvm_ActiveConnection class has these properties.

Antecedent

Data type: Msvm_LANEndpoint
Access type: Read-only
Qualifiers: Override ("Antecedent")

A reference to an instance of the Msvm_LANEndpoint class that represents the service access point (SAP) that is configured to communicate or is actively communicating with the dependent SAP. In an unidirectional connection, this SAP is the one that is transmitting.

Dependent

Data type: CIM_LANEndpoint
Access type: Read-only
Qualifiers: Override ("Dependent")

A reference to an instance of the Msvm_LANEndpoint class that represents the SAP that is configured to communicate or is actively communicating with the antecedent SAP. In an unidirectional connection, this SAP is the one that is receiving.

IsUnidirectional

Data type: boolean
Access type: Read-only

If this property is True, this connection is unidirectional; otherwise, this connection is bidirectional. When a connection is unidirectional, the "speaker" should be defined as the Antecedent reference. In a bidirectional connection, it does not matter whether the selected access point is the Antecedent or Dependent. This property is inherited from CIM_ActiveConnection.

OtherTrafficDescription

Data type: string
Access type: Read-only

This property is inherited from CIM_ActiveConnection, but it is not used.

TrafficType

Data type: uint16
Access type: Read-only

This property is inherited from CIM_ActiveConnection, but it is not used.

Remarks

Access to the Msvm_ActiveConnection class might be restricted by UAC Filtering. For more information, see User Account Control and WMI.
