In the present embodiment, equipment under test is arranged in ethernet test network, compare by the corresponding contents in the state of each port of equipment under test and the running status of ethernet network and preset standard that detection is obtained, and judge according to comparative result whether the first operation action of this equipment under test has consistency with this preset standard.
In the present embodiment, preset standard is IEC61375-2-5 standard preferably, and this standard is the international standard of electric traction power source and train bus-line.If equipment under test meets this standard, show equipment under test can and the ethernet device produced of the ethernet device manufacturer of country variant, different regions between carry out interoperability, the test result that this method obtains will be more reliable, practical.It should be noted that, in other embodiments of the invention, this preset standard can also be selected other reasonable standards, the invention is not restricted to this simultaneously.
Fig. 1 shows the just flow chart of operation action conformance test method of ethernet device in the present embodiment.
As shown in Figure 1, first, in top node testing procedure S101, equipment under test is arranged on to the end of Ethernet, form the top node of Ethernet, according to different content measurements, detect the corresponding port connected state of equipment under test and the running status at Ethernet networking, obtain top node test result.
In the present embodiment, top node test comprises: port blocked state verification, its for the end port (not with the port of other equipment connections of ethernet network) of testing equipment under test whether in blocked state; The selected test of top node, it is for testing described equipment under test and select the mode of top node by identification code and whether the corresponding contents of described preset standard mating; Intermediate node is lost test, and it is transferred to the process of power-off by energising for the reference device being connected with the intermediary interface of ethernet network, detects the running status of ethernet network; Intermediate node adds test, and it is transferred to the process of energising by power-off for the reference device being connected with the intermediary interface of ethernet network, detects the running status of ethernet network; Original intermediate node adds test, its for the reference device energising being connected with the intermediary interface of ethernet network after power-off the again process of energising again, detect the running status of ethernet network; Just test running time, it completes the just needed time of operation for testing ethernet network.
It should be noted that, in other embodiments of the invention, top node test can also comprise other rational content measurements, the invention is not restricted to this.
Again as shown in Figure 1, in intermediate node testing procedure S102, equipment under test is arranged on to the stage casing of Ethernet, form the intermediate node of ethernet network, and according to different content measurements, correspondingly detect the running status of ethernet network, obtain intermediate node test result.
In the present embodiment, intermediate node test comprises: endpoint node is lost test, and it is converted to the process of power-off, the running status of detection ethernet network from energising for the reference device being connected with Ethernet end interface; Endpoint node adds test, and it is converted to the process of energising from power-off for the reference device being connected with Ethernet end interface, detects the running status of ethernet network; Marshalling connects hangs test, and it is converted to the process of connection by disconnection for the connection between the reference device being adjacent at equipment under test, the running status of test Ethernet.
It should be noted that, in other embodiments of the invention, intermediate node test can also comprise other reasonable content measurements, the invention is not restricted to this.
Again as shown in Figure 1, in the present embodiment, in passive bypass testing procedure S103 by equipment under test in off-position, and detect the now connected state of each port of equipment under test, thereby obtain passive bypass test result.
Finally, in step S104, judge whether top node test result, intermediate node test result and passive bypass test result mate with preset standard.If coupling, judges in step S105 that the first operation action of this equipment under test is identical with preset standard, the first operation action of this equipment under test has consistency; Otherwise the first operation action that judges this equipment under test in step S106 does not have consistency, and this equipment under test cannot be used in Ethernet.In the present embodiment, in the time that top node test result, intermediate node test result and passive bypass test result are all identical with corresponding contents in preset standard, just judge that the first operation action of this equipment under test has consistency.
This method testing process is simple and convenient, can effectively examine the just critical behavior of operation of tested ethernet device, thereby realize to tested ethernet device just operation action characteristic and preset standard whether there is consistency and comparatively intactly verify, for the extensive use of equipment under test in Ethernet provides guarantee and foundation.
The present invention also provides just operation action consistency test device of a kind of ethernet device, and this device utilizes the just consistency of operation action of said method test ethernet device.For different content measurements, the testing apparatus that the present embodiment provides is correspondingly configured to different structures.
For convenience of description, in the present embodiment, equipment under test and reference device all have 4 ports (X1, X2, X3, X4), wherein, X1 port and X3 port are one group of " entering-leave (Ingress-Egress) " port pair, X2 port and X4 port are one group of " enter-leave " port pair, between the port of different " enter-leave " port centerings, do not have annexation.Meanwhile, Ethernet interface also correspondingly has four ports (X1, X2, X3, X4), and if no special instructions, each port of equipment under test and reference device is be connected corresponding with Ethernet interface all, but the invention is not restricted to this.
According to the relevant regulations of IEC61375-2-5 standard, when equipment under test 204 is when off-position (in passive bypass ports state), connection between its X1 port and X3 port is in conducting state, and the connection between X2 port and X4 port is also in conducting state.
So according to above principle, adopt the structure going out as shown in Figure 2 to test the passive bypass ports state of tested ethernet device in the present embodiment.
As shown in Figure 2, respectively first network diagnosis unit 207 is connected with X1 port and the X3 port of equipment under test respectively with second network diagnosis unit 208.In the time testing, first guarantee that equipment under test is in off-position, utilize subsequently first network diagnosis unit 207ping second network diagnosis unit 208, and whether detection can lead to by ping.
If can ping logical, show that the X1 port of equipment under test 204 and X3 port are in conducting state, it meets the relevant regulations of IEC61375-2-5 standard.If cannot ping logical, show that the X1 port of equipment under test 204 and X3 port are in nonconducting state, it does not meet the relevant regulations of IEC61375-2-5 standard.
According to above principle, in four ports of traversal equipment under test, the connection combination of any two ports, tests respectively the conducting state that each connects combination subsequently.If same group " enters-leaves that " right two ports of port are all in conducting dress state, non-same group " enters-leaves that " right two ports of port are all in nonconducting state, only have being connected in conducting state between X2 port and X4 port that be connected between X1 port and X3 port, show that equipment under test 204 mates with the corresponding contents in preset standard, equipment under test 204 has passed through passive bypass ports state verification.
According to the relevant regulations of IEC61375-2-5 standard, for the ethernet device in Ethernet end, its end port (not with Ethernet in the port of other equipment connections) in blocked state.And for the port in blocked state, only have IEEE802.3 management frames to allow to enter or leave from this port, and the frame of every other type all will be lost in the process by this port, and this port also cannot carry out address learning simultaneously.
So according to above principle, adopt the structure of the testing equipment going out as shown in Figure 3 to test the port blocked state of tested ethernet device in the present embodiment.
As shown in Figure 3, first equipment under test 204 is connected with the first Ethernet interface 201 of Ethernet, is connected with the second Ethernet interface 202 and three-ethernet interface 203 respectively with reference device 206 with reference to equipment 205.Now equipment under test 204 can be regarded the top node in Ethernet as, and reference device can be regarded the intermediate node of Ethernet as.
Subsequently first network diagnosis unit 207 is connected with the X1 port of the first Ethernet interface 201.In the present embodiment, network diagnosis unit 207 is for to have the personal computer of network diagnostic function, but the invention is not restricted to this.
Then each ethernet device is connected with power supply by corresponding power supply switching unit respectively.As shown in Figure 3, in the present embodiment, equipment under test 204 is connected with power supply 208 by power supply switching unit K1, and reference device 205 is connected with power supply 208 with power supply switching unit K3 by power supply switching unit K2 respectively with reference device 206.
Carry out port blocked state verification time, first closed power supply switching unit K1～K3.First utilize first network diagnosis unit 207 to carry out the instruction of X3 port in ping Ethernet interface 201 subsequently, finally detect and whether can lead to by ping, and check the MAC Address that whether has network diagnosis equipment 207 in address resolution protocol (Address Resolution Protocol, referred to as the ARP) table of equipment under test 204.
If the first networking diagnosis unit 207 cannot ping the X3 port of logical equipment under test, in the ARP of equipment under test table, there is not the MAC Address of first network diagnosis unit 207 simultaneously.So according to the relevant regulations of EC61375-2-5 standard, represent that the X1 port of equipment under test is now in blocked state.
Subsequently network diagnosis unit 207 is connected with the X2 port of the first Ethernet interface 201, and tests and whether pass through pingX4 port test X2 port in blocked state, its principle is identical with X1 port test principle, does not repeat them here.
Because when the port block state of test equipment under test, need to all test each port of equipment under test, so next need X3 port and X4 port to equipment under test 204 to test.
When X3 port to equipment under test 204 and X4 port are tested, by being connected of equipment under test 204 and three-ethernet interface 203, and adopt the principle identical with testing X1 port to test respectively the blocked state of equipment under test X3 port and X4 port.
If four ports of equipment under test 204 all meet the relevant regulations of EC61375-2-5 standard, represent that equipment under test 204 mates with the corresponding contents in preset standard, equipment under test 204 has passed through port blocked state verification.
In addition,, in the time that equipment under test 204 is connected with the first Ethernet interface 201, can also carry out that test is lost in the selected test of top node, intermediate node, intermediate node adds test, original intermediate node add test and just test running time.
As shown in Figure 4, in the time carrying out above-mentioned test, need between the first Ethernet interface 201 of Ethernet and the second Ethernet interface 202 series connection on data acquisition unit 209.Data acquisition unit 209 can be in the situation that not affecting ethernet network communication, realizes 100% of Ethernet data to sealing in circuit and catch, and can after the data decode capturing, store in the storage medium of self configuration.Data acquisition unit 209 can also be uploaded to coupled data processing unit 210 in real time by the Ethernet data collecting simultaneously.
Data processing unit 210 can judge whether the first operation action of equipment under test mates with the corresponding contents in preset standard according to the Ethernet data receiving, and then whether the first operation action of judging this equipment under test has consistency.
In the present embodiment, data acquisition unit 209 adopts data logger, data processing unit 210 adopts the personal computer that has the general-purpose operating system and have man-machine interface, but the invention is not restricted to this, in according to other embodiments of the invention, data acquisition unit and data processing unit all can adopt other reasonable equipment.For example data acquisition unit can also adopt the personal computer that data packet capturing software is installed, and now needs the section of carrying out all to shine upon configuration.
According to the relevant regulations of IEC61375-2-5 standard, for the top node in Ethernet, its identification code CstUU ID is lower, identification code ETBN ID is 1.
So in the present embodiment, in the time carrying out the selected test of top node, first build ethernet test topology according to above-mentioned requirements, and described equipment under test arranged to the end of ethernet test topology, be i.e. the first Ethernet interface 201 places.The power supply of conducting data acquisition unit 209 subsequently, makes it start image data, and closed power supply switching unit K1～K3, makes the power turn-on of each equipment in ethernet test topology.The Ethernet data finally by data processing unit 210, data acquisition module 207 transmission that receive is analyzed, extract and analyze TTDP TOPOLOGY frame wherein, and judge according to the related data in this frame whether equipment under test 201 and reference device 203 have the ETBN ID that lower CstUU ID and value are 1.
If the CstUUID of equipment under test 201 and reference device 203 is lower and ETBN ID value is 1, so show the top node that equipment under test 201 is Ethernet, it meets the relevant regulations of IEC61375-2-5 standard, and this equipment has passed through the selected test of top node.
In the process that the Ethernet data that data processing unit 210 comes data acquisition module 207 transmission that receive is analyzed, can also judge whether Ethernet completes just operation according to the first running status flag bit in Ethernet data designated frame.Data processing unit 210 can be added up and be closed into just the running status flag bit needed duration that changes from power supply switching unit, and this duration namely Ethernet completes the just needed time of operation.
According to the relevant regulations of IEC61375-2-5 standard, in the time that Ethernet generation intermediate node is lost, will not there is not just operation in Ethernet, the loss of intermediate node can be detected simultaneously.
So in the present embodiment, when underway intermediate node is lost test, on the basis of the Ethernet topology of building in the time carrying out the selected test of top node, first the power supply of conducting data acquisition unit 209, make it start image data, and closed power supply switching unit K1～K3, make the power turn-on of each equipment in ethernet test topology.
Deenergization switching unit K2 subsequently, so that reference device 205 power-off.Because in the present embodiment, reference device 205 can be regarded the intermediate node of ethernet network as, loses process so said process can be regarded as Ethernet intermediate node.
The Ethernet data finally by data processing unit 210, data acquisition module 209 transmission that receive is analyzed, and whether there is first operation according to analysis result judgement Ethernet after intermediate node is lost, also judge whether to detect the loss of intermediate node simultaneously.
If when after reference device 205 power-off, there is not just operation in Ethernet, and the loss of intermediate node detected.Show that so equipment under test 204 meets the relevant regulations of IEC61375-2-5 standard, this equipment has passed through intermediate node and has lost test.
According to the relevant regulations of IEC61375-2-5 standard, when Ethernet generation intermediate node adds fashionablely, can there is just operation in Ethernet, new network topology can be detected simultaneously.
So in the present embodiment, when underway intermediate node adds test, on the basis of the Ethernet topology of building in the time carrying out the selected test of top node, first the power supply of conducting data acquisition unit 209, make it start image data, and closed power supply switching unit K1 and K3, make the power turn-on of each equipment except reference device 205 in ethernet test topology.
Closed power supply switching unit K2 subsequently, so that the power turn-on of reference device 205.Because reference device 205 can be regarded the intermediate node of Ethernet as, so the power supply of above-mentioned reference device 205 can be regarded as Ethernet intermediate node adition process by the process that is disconnected to conducting.
The Ethernet data finally by data processing unit 210, data acquisition module 209 transmission that receive is analyzed, and whether there is first operation according to analysis result judgement Ethernet after intermediate node adds, also judge whether to detect the loss of intermediate node simultaneously.
If when after reference node 205 energisings, there is just operation in Ethernet, and new network topology detected.Show that so equipment under test 204 meets the relevant regulations of IEC61375-2-5 standard, this equipment has passed through intermediate node and has added test.
According to the relevant regulations of IEC61375-2-5 standard, after the intermediate node of Ethernet is by the power-off after an action of the bowels of switching on, power on again, there is original intermediate node and add fashionable in Ethernet.To can not there is just operation in Ethernet so.
So in the present embodiment, add when test carrying out original intermediate node, on the basis of the Ethernet topology of building in the time carrying out the selected test of top node, first the power supply of conducting data acquisition unit 209, make it start image data, and closed power supply switching unit K1, K2 and K3, make the power turn-on of each equipment in ethernet test topology.

The Ethernet data finally by data processing unit 210, data acquisition module 207 transmission that receive is analyzed, and according to analysis result judgement Ethernet after original intermediate node adds, whether first operation has occurred.
If when reference node 205 is by being conducting to power-off more again after energising, there is not just operation in Ethernet.Show that so equipment under test 204 meets the relevant regulations of IEC61375-2-5 standard, this equipment has passed through intermediate node and has added test.
In the present embodiment, the intermediate node test of Ethernet comprises: endpoint node is lost test, endpoint node adds test, marshalling even to hang test etc.When underway intermediate node test, equipment under test can not be in the end of Ethernet topology, and its both sides all need to be connected with other ethernet devices.
So according to above principle, in the present embodiment, when underway intermediate node test, equipment under test 204 is connected with the second Ethernet interface 202, reference device 205 is connected with the first Ethernet interface 201 and three-ethernet interface 203 respectively with reference device 206.Now equipment under test 204 can be regarded as the intermediate node of built Ethernet topology, and reference device 205 and reference device 206 can be regarded as top node, i.e. endpoint node.
In the time carrying out the test of endpoint node loss, the first power supply of conducting data acquisition unit 209, makes it start image data, and closed power supply switching unit K1, K2 and K3, makes the power turn-on of each equipment in ethernet test topology.
Deenergization switching unit K1 subsequently, so that the power supply of reference device 205 disconnects.Because reference device 205 can be regarded the endpoint node of Ethernet as, so the power supply of above-mentioned reference device 205 be can be regarded as the loss process of Ethernet endpoint node by the process that is conducting to disconnection.
