1. A control and/or monitoring system, the system comprising:
a host device on which an application, for generating a requesting Ethernet frame, in a first Ethernet frame format, for deriving information about an industrial Ethernet network or about one or more industrial Ethernet devices connected to the industrial Ethernet network, can be run; and
an industrial Ethernet tunnel device which is adapted to communicate with the host device, wherein the system is configured to:
inject the requesting Ethernet frame through the industrial Ethernet tunnel device; and
receive an answer in the first Ethernet frame format in the host device, which answer is transmitted through the industrial Ethernet tunnel device;
wherein the application is executable to establish a filtering rule in the industrial Ethernet tunnel device which filters out from Ethernet frames transmitted within the industrial Ethernet network an answering Ethernet frame which corresponds to the answer which is to be received in the host device, while the remaining Ethernet frames which are not related to the answer are not transmitted from the industrial Ethernet tunnel device to the host device.
