For certain Non-Profinet devices the firmware reports invalid toplogy information in SNMP and record objects:

• PDPortDataReal might contain a NameOfStation
• lldpXPnoRemPortNoS is created from PortMacAddress if Chassis Mac Address could not be determined

The returned information should behave as defined in specification. PDPortDataReal should contain a NameOfStation only for Profinet Devices  (Detected by existence of Profinet Chassis Id LLDP TLV) and lldpXPnoRemPortNoS  should be omitted the device is a Non-Profinet Device and the chassis mac could not be determined.
