This object holds the managedObjectClass value from a cmisEventReport, and is only meaningful when the device is running with the HP OpenView DM product. It tells the receiving management station what CMIP-defined class of managed object the event pertains to, which is needed to interpret CMIP-originated events correctly. As an example, this field might carry a class identifier for a network interface object when a CMIP-managed device reports a fault on that interface.
