Further description:
The SNMP provider uses a GET-NEXT operation to retrieve instance information from a device. The device may return keyed property information that is inconsistent with the MOF definition of the class being retrieved. Where keyed properties are marked with the virtual_key qualifier value set to True, these properties are derived from the SNMP instance information present within the variable binding list of the non-virtual-keyed and non-keyed properties present within the class definition. These properties are not initialized because the typing information is inconsistent with the MOF class definition.
