Definitions
- TITLE Method for configuring an Ethernet switch in an on-board network of a motor vehicle
- the present invention relates generally to the field of on-board networks in the automobile, and more particularly to the testing of a local network on-board in a motor vehicle.
- It relates to a method for configuring an Ethernet switch of such an on-board network, implemented for the purpose of testing said network.
- Ethernet network and in particular an Ethernet network operating in switched mode over an Internet Protocol (IP)
- IP Internet Protocol
- This star topology is organized around an Ethernet switch which interconnects all the equipment of the on-board Ethernet network.
- IP Internet Protocol
- the transit through the network of a data frame from a source device to a destination device necessarily involves a passage of this frame by the Ethernet switch.
- OSI Open Systems Interconnection
- the Ethernet switch is a layer 2 device, called the link layer, for which the data unit is the frame. Its role is to direct the data frames it receives from source equipment to a destination device, using a physical addressing system.
- This physical addressing system is that of the medium access control sublayer (also called MAC layer, from the English “Medium Access Control”) which is the lower half of the data link layer of the model. OSI.
- the Ethernet switch relies on a database or CAM table (from the English “Content Addressable Memory”) which allows it to determine which equipment is connected to which port of the switch, and to know how to orient the data. based on the addresses of the source and destination equipment which are contained in the frames.
- a table is empty when the switch is initialized. The frames are therefore initially distributed on all the ports of the switch. The table is then filled and updated as and when the switch is used, thus leading to associating each port of the switch with one or more given MAC addresses of an item of equipment on the onboard Ethernet network.
- the switch transmits this frame only on the appropriate port, the other ports therefore remaining free for other transmissions that can happen simultaneously.
- Each Ethernet switch includes its own configuration registers at the hardware level. These registers determine the operating parameters of the Ethernet switch. For example, it is through these configuration registers that it is possible to activate or deactivate a port, to modify the behavior of a port with respect to a given MAC address (by example to control the filtering of all the frames coming from, or intended for the equipment corresponding to this MAC address) or, in general, to modify the behavior of the switch compared to the data which it makes pass.
- Document CN 102355377 discloses a test system and a complete test method for an Ethernet switch. According to this method, a first port of test equipment is connected to any port of the switch tested, a second port of test equipment is connected to any interface of layer 3 of equipment auxiliary test, and other ports of the switch under test are connected with the Layer 3 interfaces of the auxiliary test equipment.
- the document FR 2868567 discloses a system for simulating and testing equipment of a network of the AFDX type (i.e. a communication network of the switched Ethernet type).
- This system uses non-specific computing means such as a simulation layer driving at least one Ethernet controller, and an Ethernet switch on the market.
- Document US 20180072250 discloses a test device and the associated methods in an on-board Ethernet network of a motor vehicle.
- a management controller is connected to the physical layer to manage the ports.
- the invention aims to eliminate, or at least mitigate, all or part of the disadvantages of the aforementioned prior art.
- a first aspect of the invention proposes a method for configuring an Ethernet switch included in a first piece of equipment of an on-board Ethernet network of a motor vehicle which is suitable for connecting together, via the Ethernet switch, the first device and at least one second device of the on-board Ethernet network, distinct from said first device, said method comprising the steps of:
- the invention it is possible to configure an Ethernet switch with generic commands produced by the test tool of the motor vehicle manufacturer.
- the commands generated by the test tool and used to configure an Ethernet switch can be identical regardless of the switch concerned.
- the dedicated software module of the equipment ECU that integrates the switch allows standard commands to be interpreted so that the switch can be configured independently of the hardware configuration of the switch. Thanks to this software module, the equipment's computer can thus act on the specific switch it integrates, using configuration commands appropriate to the technology of said switch, regardless of the generic commands it receives from the test tool.
- Embodiments taken individually or in combination, further provide that:
- the software module can be stored in a memory of the on-board network equipment to which the Ethernet switch is integrated;
- the configuration command for the Ethernet switch can be issued by the test tool to the first device via a link established on the on-board network, between said test tool and said first device, while the test tool is connected via said on-board network to a port of the Ethernet switch;
- the configuration command for the Ethernet switch can be sent by the test tool to the first device while said test tool is connected to the first device by another network, in particular a multiplexed network such as a network of the following type: LIN (from English "Local Interconnect Network ”) or CAN (from the English" Controller Area Network ");
- a multiplexed network such as a network of the following type: LIN (from English "Local Interconnect Network ”) or CAN (from the English" Controller Area Network ");
- a generic switch configuration command can comprise at least one frame, composed of a plurality of bytes of useful data, and adapted to define at least one action that the Ethernet switch must perform in order to perform a test service determined from a list of determined test services, said test service being adapted to modify the operation of the Ethernet switch during the transit of data in the on-board network of the motor vehicle;
- - the list of test services may include:
- VLANs virtual local area networks
- the first equipment of the on-board network of the motor vehicle can be included in the list made up of the following equipment: a communication module centralizing the connection electronics to the outside (in order to receive mobile networks, TNT, RNT, AM / FM , GPS) and towards the interior of the motor vehicle, an infotainment module, a connection gateway to a network external to the motor vehicle, an electronic trajectory corrector.
- - generic commands for configuring an Ethernet switch can respond to a communication protocol included in the list made up of the following protocols: MQTT, WebSocket, SOME / IP or a proprietary protocol.
- the invention also relates to equipment of a motor vehicle comprising an Ethernet switch for connecting the equipment to other equipment via an on-board Ethernet network, and further comprising a software module and means for setting implementing all the steps of the method according to the first aspect.
- a final aspect of the invention relates to a motor vehicle comprising equipment according to the second aspect.

- FIG. 5 is a schematic representation of examples of data frames associated with the various configuration commands of an example of test service.
- the Ethernet switch 103 shown in the figure is integrated into equipment 101 of an on-board network of a motor vehicle (not shown in FIG. 1).
- the equipment 101 also incorporates a computer 102, with at least one processor and memory, which communicates directly with the switch 103.
- the Ethernet switch is equipped with three ports 104 which allow it, in normal use , to pass data from a source device to at least one destination device.
- the number of ports of such a switch is not limited to three and is at least greater than two.
- an Ethernet switch on the market has eight ports.
- on-board equipment may include more than one switch such as the switch 103 shown. For example, it can include two such switches of eight ports each, thus totaling sixteen ports.
- a test equipment (or tool) 105 is connected (that is to say connected) to one of the ports 104 of the switch 102.
- this equipment 105 issues configuration commands of the Ethernet switch 103 which are specifically adapted to this switch, so that they can be correctly interpreted and executed in the switch.
- the configuration of the switch can only be carried out if its own configuration commands are known beforehand to the test tool.
- FIG. 2 schematically shows a motor vehicle 205 having an on-board network 206 in which the method according to the invention can be implemented.
- on-board network is meant, in the context of the present description, a local communication network connecting together a plurality of on-board equipment of the vehicle.
- the on-board network connects four pieces of equipment 201, 202, 203 and 204 in a star topology.
- the number of devices of the network represented is not limiting, but is necessarily greater than or equal to two.
- it is the equipment 201 which incorporates an Ethernet switch (which is shown in FIG. 3 on which it bears the reference 303) which makes it possible to interconnect all the equipment of the on-board network 206.
- the equipment making up the on-board network can be any known equipment, of the electronic equipment type, of a motor vehicle.
- each piece of equipment that can be automotive is included in the list made up of the following pieces of equipment: a communication module centralizing the connection electronics to the outside (in order to receive mobile networks, TNT, RNT, AM / FM, GPS ) and towards the interior of the vehicle automobile, an infotainment module, a connection gateway to a network external to the motor vehicle, an electronic trajectory corrector.
- FIG. 3 shows an Ethernet switch 303 integrated into the equipment 201.
- the equipment 201 also includes a computer 301 which communicates directly with the Ethernet switch 303.
- the equipment 201 differs from the equipment 101 of the prior art, however. what its computer additionally incorporates a software module 302.
- this software module is stored in a memory of the computer 301 of the equipment 201.
- This software module 302 is adapted to generate, from generic commands for configuring an Ethernet switch, configuration commands specific to the Ethernet switch integrated in the first device. In other words, it allows the computer to be able to interpret any standard configuration command (from the point of view of the test tool) and translate it into a form that the Ethernet switch can interpret and execute, that is to say a command specific to this computer.
- the configuration of the Ethernet switch can here be carried out by means of test equipment 305 which, for this purpose, is connected to one of the ports 304 of the Ethernet switch 303, by a cable.
- the equipment issues a generic command to configure the Ethernet switch which is transmitted to the computer of the equipment 201 via the switch 303.
- the test equipment can be connected to the computer via another on-board network, that is to say a network different from the Ethernet network 206 to which belongs the Ethernet switch 303 to be tested.
- It can for example be a conventional multiplex network (i.e. not a network Ethernet) of the motor vehicle, for example a network of the LIN type (from the English “Local Interconnect Network”) or of the CAN type (from the English “Controller Area Network”).
- This embodiment is represented in FIG. 3 by a link 307 between the test tool and the on-board equipment 201.
- the link 307 has the function of transmitting a command to configure the Ethernet switch 303 from the test tool 305.
- This embodiment is useful for testing the equipment on board in vehicles in which all the equipment are not connected to the onboard Ethernet network, but in which certain equipment is connected to the conventional multiplexed network of LIN or CAN type, or other.
- a generic command for configuring an Ethernet switch consists of at least one frame, itself composed of a plurality of bytes of useful data, and which is arranged to define at least one action that the Ethernet switch must perform .
- This command is called generic in the sense that it has not been the subject of any adaptation in order to be able to be interpreted by the switch for which it is intended, which can wait for commands in a specific format which depends on the manufacturer of the switch Ethernet. It is simply a standard command that can be issued by generic test equipment from the car manufacturer wishing to test the equipment on board the vehicle, during a test carried out for example at the end of assembly of the vehicle in the factory. Examples of such generic configuration commands will be described later.
- such a configuration command responds, according to the mode of implementation of the method, to a given communication protocol.
- the protocol can be included in the following list: EMP, SOME / IP, MQTT, WebSocket. This list is not exhaustive. It can also be a proprietary protocol.
- step 401 of the method consists in the reception, by the computer 201, of at least one generic command for configuring the Ethernet switch coming from the test equipment 305.
- Step 402 consists of the generation, by the software module 302 executed by the computer 301 of the equipment 201, of a configuration command of the Ethernet switch in the form of a configuration command specific to said Ethernet switch. Thanks to the software module 302, each generic configuration command is converted into a command specific to the Ethernet switch under test, to be specifically interpreted and executed by this Ethernet switch 303.
- step 403 consists of the execution, under the command of the computer of the equipment 201, of the specific configuration command received from the computer 301. This command results in the modification of the configuration registers of the switch and, consequently, the modification of the switch behavior with regard to the data which pass through it.
- the method allows any equipment which integrates an Ethernet switch to receive generic configuration commands from a test equipment and to convert them into a configuration command specifically adapted to the Ethernet switch which he integrates.
- a generic configuration command consists of a frame of useful data.
- the transmission by the test tool of a sequence of frames makes it possible to control the implementation of a particular test service on the side of the Ethernet switch which receives the frames in question.
- several configuration commands can form a test service whose object is to modify the operation of the Ethernet switch during the transit of data in the on-board network of the motor vehicle.
- a test service is defined by several configuration commands which have the effect, when executed, of modifying the behavior of the Ethernet switch.
- the computer receives a frame whose various bytes of useful data make it possible to define in detail the action to be executed, according to protocol specifications known to the test tool 305 and to the software module 302.
- “Bytes of useful data” here means the bytes of a frame which relate only to the command to be executed and does not provide protocol encapsulation information such as the identification of source and destination addresses, the length of the frame or the FCS field (from the English “Frame Check Sequence”) which contains a frame control code (or CRC code, from the English “Cyclic Redundancy Code”).
- the expressions “byte” or “byte of useful data” are used interchangeably to designate a byte of useful data. Note that, as is well known to those skilled in the art, each byte consists of 8 bits, the value of which can be either 0 or 1.
- the frame consists of a variable number of bytes of useful data, which depends on the action to be performed.
- the first byte of the frames associated with the different commands of the service is used in the same way in all cases. This is used to define whether the computer must configure the switch ports in a manner which is defined by the following bytes (SET function), or whether the computer must interrogate the switch to obtain the status of each port in return (function GET). For example, if all the bits of this byte are at 0 then the computer will have to proceed with the configuration (SET function), and if the last bit is worth 1 then the computer must carry out the interrogation of the switch (GET function).
- the frame structure of a configuration command which consists in activating or deactivating the ports of a switch is described by way of a non-limiting example.
- This function is based on the use of a 5-byte 501 frame, the first byte of which is defined as mentioned above.
- the second and third bytes form a binary mask which makes it possible to indicate which port (s) of the switch is (are) concerned with the command, it being observed that with two bytes for this mask you can manage up to sixteen different ports.
- the value 1 for a bit of the second and third bytes indicates that a given port (identified by the rank of the bit concerned in the two bytes of the frame) is concerned, while the value 0 indicates that the corresponding port should not not be affected by the order. If you have to manage more than sixteen ports, then more bytes can be devoted to the coding of this binary mask.
- the fourth and fifth bytes can for example specify the desired statuses for each port (for example status "activated” or “deactivated” if the test service consists in activating or deactivating the switch ports).
- the values of the bits of the fourth and fifth bytes allow respectively to activate (with the value 1) or deactivate (with the value 0) the port corresponding to the bit in question.
- bit 7 of the second byte is set to 1 and bit 7 of the fourth byte is set to 1, then port 15 of the Ethernet switch is enabled.
- bit 6 of the second byte is set to 1 and bit 6 of the fourth byte is set to 0, then port 14 of the Ethernet switch is disabled.
- bit 5 of the second byte has the value 0 and bit 5 of the fourth byte has the value 1 then the status of port 13 remains unchanged.
- the interrogation proper uses a frame 502 which is made up of only one byte of payload. Based on the value of the bits in the first byte, as explained above, the interrogation command of the switch is executed.
- the response to this command is done in a 503 frame (RESPONSE function) composed of three bytes, in the example considered here a switch having at most sixteen ports, which the switch returns to the computer in response to the query on the status of each port.
- the number of switch ports is indicated by the value of the bits of the first byte and the respective status of each port is indicated by the value of the bits of the second and third bytes.
- the four least significant bits of the first byte indicate the number of switch ports, converting the binary values to a hexadecimal system (in which you can encode sixteen different values on just four bits).
- a bit of rank corresponding to a given port of the switch and whose value is 1 means that the port is activated, or conversely that the port is deactivated if the bit in question is set to 0 .
- the software module allows any computer integrated into equipment in an on-board network to identify the action to be performed in response to a given command. It is the manufacturer of this equipment who must implement, in his computer, calling the appropriate software functions to configure the Ethernet switch in response to a given generic command. In this way, regardless of the switch to be configured, the configuration commands generated by the test equipment can be the same.
- test services are achievable using generic configuration commands. These other test services can be included in the following list of nonlimiting examples: - the activation or deactivation of a filtering of data frames responding to ARP, RTP, IEEE1722 or IEEE1733 protocols as input and / or output on one or more ports of the switch;
- VLANs virtual local area networks
- port mirroring in English
- filtering is applied on the basis of the source and / or destination MAC addresses, virtual networks (or VLANs, from the Virtual Local Area Network) or on the basis of the ports; port filtering is applied to incoming and / or outgoing traffic;
