An embodiment of the present invention provides a backplane data channel testing apparatus based on an ATCA architecture, as shown in fig. 2, 3, and 4, the testing apparatus of the embodiment is divided into three types, which are respectively used for testing a Fabric service data port of a service slot and an upper connection slot of a tested backplane, a Base management data port channel of the service slot and the upper connection slot, and a Base management data port channel between a first switching control board and a second switching control board (a master/slave switching control board). Embodiments thereof are described below based on these three cases, respectively.
The tested backboard based on the ATCT architecture is mainly provided with the following data channels: sync Clocks, Update Channels, textile interface, Base interface, IPMB Star, test line and POWER. The high-speed data channels include Fabric interface and Base interface. The invention aims to solve the test problem of the two data channels.
According to the ATCA definition, the Fabric interface and the Base interface are distributed in a double star shape on the tested backboard, as shown in FIG. 1.
In order to achieve the purpose, the data channel to be tested is divided into three parts, different test paths are adopted for the three parts, and the test and the verification are completed by adopting the same test method.
The first part is the Fabric service data port channel test of 1-6 slot positions and 9-14 slot positions, and the test system is configured according to the mode of figure 2, and the specific method steps are as follows:
as shown in fig. 2, a testing apparatus and a connection method for testing a Fabric service data port channel on a backplane are provided, in which a slot No. 7 and a slot No. 8 are respectively inserted into an exchange control board, a slot No. 6 is inserted into an upper connection board, and the rest slots are inserted into a testing tooling board; two of the ports of the upper connecting plate are connected to the ports of the flow test instrument, and the other ports are connected with each other in pairs by optical fibers.
The distribution of the Fabric service data port channels on the backplane can be seen from fig. 1 and 5. As shown in FIG. 5, the Fabric service data ports of slots 1-6 and 9-14 on the backplane are from the service host switch chips on the switch Fabric of slot 7 and slot 8. Specifically, a service master switching chip of a switching control board of a slot position 7 or a slot position 8 is located at the center of a double star topology structure, according to the definition of the ATCA, the service master switching chip leads a data port thereof to each service slot position and an upper connection slot position through a backboard connecting line, the number of channels of each slot position is an even number, such as 2, 4, 8, 12 and the like, the specific number is determined by the port number requirement of the system, the type of the data line of the connecting line is a differential line, and the differential line receiving and transmitting direction of each port is at least one pair.
For better understanding of the port ring connection principle mentioned in the embodiment of the present invention, as shown in fig. 6, it is assumed that a service master switch chip has 20 ports, which are allocated to each service slot and upper connection slot according to the above-mentioned principle, and further it is assumed that a port 1 and a port 20 are allocated to the upper connection slot, then the embodiment uses the port 1 and the port 20 as an input port and an output port of test data, respectively, and connects to a corresponding port of an bleeding test meter. Further, assuming that test data enters a test loop from the port 1 of the service main switching chip and enters the interior of the service main switching chip, a port VLAN of the service main switching chip is configured, so that the port 1 and the port 2 are configured to be the same as 1 VLAN1, and then the test data can only flow out from the port 2 after entering the service main switching chip from the port 1; furthermore, the port 2 and the port 3 use a test tooling plate to cross and ring the transceiving data channels of the two ports, that is, the transmitting differential line of the port 2 is butted with the receiving differential line pair of the port 3, and the transmitting differential line of the port 3 is butted with the receiving differential line pair of the port 2, so that the test data flowing out of the port 2 can only flow into the port 3; furthermore, after the test data enters the service main switching chip from the port 3, the port 3 and the port 4 are configured to be 1 VLAN2, and then the test data can only flow out from the port 4 after entering the service main switching chip from the port 3; furthermore, the port 4 and the port 5 use a test tooling plate to cross and ring the transceiving data channels of the two ports, that is, the transmitting differential line of the port 4 is butted with the receiving differential line pair of the port 5, and the transmitting differential line of the port 5 is butted with the receiving differential line pair of the port 4, so that the test data flowing out of the port 4 can only flow into the port 5; and so on; finally, the test data entering the port 19 will enter the port 20 in the same VLAN10 according to the port VLAN setting of the service master switching chip, and the data of the port 20 will enter the streaming test instrument from the connection line, thereby completing the data transmission and reception of the whole loop. The above process is port 1 transmitting and port 20 receiving and vice versa. The above process only tests the connection condition of the Fabric data channel of the back plate when one exchange control plate is used, and the test method of the connection condition of the Fabric service data port channel of the other exchange control plate on the back plate is similar.
It should be clear that the embodiments of the present invention are provided with general purpose, and are only used for illustrating the implementation of the present invention, and are not used to limit the protection scope of the present invention. Specifically, the number of ports of the service main switching chip is not limited to 20, and the embodiment of the present invention only uses the number of ports of the number to facilitate description of the implementation method of the present invention; only the port 1 and the port 20 are not limited to be connected to corresponding ports of the tapping test instrument, but two ports in the upper connecting slot position can be randomly selected to be used as an input port and an output port of test data according to the convenience of the wiring condition of the test; the upper linking slot position is not limited to the slot position No. 6, or the slot position No. 9, and further, the slot position distribution of two ports for inputting and outputting test data is not limited, and the slot positions can be the slot positions No. 6, or the slot positions No. 9, or 1 slot position No. 6 and one slot position No. 9; the VLAN number of the set port VLAN is not limited, the sequence of two ports in the same VLAN is not limited, and the ports can be flexibly selected according to the convenience of wiring.
The second part is the testing of the Base management data port channel of the 1-6 slot position and the 9-14 slot position, which is similar to the testing device and the wiring mode of the Fabric service data port channel on the testing backboard, as shown in fig. 3, the testing device and the wiring mode of the Base management data port channel on the testing backboard are provided, wherein the No. 7 slot position and the No. 8 slot position are respectively inserted into the exchange control board, and the rest slot positions are inserted into the testing tool board; the RJ45 ports of the test tool boards in the slot No. 1 and the slot No. 14 are connected to the port of the streaming test instrument, and the RJ45 ports of the rest test tool boards are connected with each other in pairs by using super 5-type unshielded twisted pairs.
From fig. 1 and 5, the Base management data port channel distribution on the backplane can be seen. As shown in FIG. 5, the Base management data port channels of slots 1-6 and 9-14 of the backplane are from the management switch chips on the switch boards of slot No. 7 and slot No. 8. Specifically, the management switching chip of the switching control board of the slot position 7 and the slot position 8 is positioned at the center of the double star topology structure, the management switching chip leads the data port of the management switching chip to each service slot position and the upper linking slot position through a backboard connecting wire according to the definition of ATCA, the number of the channels of each slot position is 1, and the data type of the connecting wire is a hundred mega or giga Ethernet port;
for better understanding of the port ring connection principle mentioned in the embodiment of the present invention, as shown in fig. 6, it is assumed that the management switch chip has 20 ports, which are allocated to each service slot and upper connection slot according to the above-mentioned principle, and further it is assumed that the port 1 and the port 20 are allocated to the slot No. 1 and the slot No. 14, respectively, then the embodiment uses the port 1 and the port 20 as the input and output ports of the test data, and connects to the corresponding ports of the streaming test meter. Further, assuming that test data enters a test loop from the port 1 of the management switch chip and enters the management switch chip, the port VLAN of the management switch chip is configured, so that the ports 1 and 2 are configured to be the same as 1 VLAN1, and then the test data enters the management switch chip from the port 1 and only flows out from the port 2; furthermore, the port 2 and the port 3 use a test tooling plate to cross and ring the transceiving data channels of the two ports, that is, the transmitting differential line of the port 2 is butted with the receiving differential line pair of the port 3, and the transmitting differential line of the port 3 is butted with the receiving differential line pair of the port 2, so that the test data flowing out of the port 2 can only flow into the port 3; furthermore, after the test data enters the service main switching chip from the port 3, the ports 3 and 4 are configured to be the same as 1 VLAN2, and then the test data can only flow out from the port 4 after entering the management switching chip from the port 3; furthermore, the port 4 and the port 5 use a test tooling plate to cross and ring the transceiving data channels of the two ports, that is, the transmitting differential line of the port 4 is butted with the receiving differential line pair of the port 5, and the transmitting differential line of the port 5 is butted with the receiving differential line pair of the port 4, so that the test data flowing out of the port 4 can only flow into the port 5; and so on; finally, the test data entering the port 19 will enter the port 20 in the same VLAN10 according to the port VLAN setting of the management switch chip, and the data of the port 20 will enter the streaming test instrument from the connection line, so as to complete the data transmission and reception of the whole loop. The above process is port 1 transmitting and port 20 receiving and vice versa.
In the process, the connection condition of the Base management data port channel of the back plate when only one exchange control plate is tested, and the connection condition test method of the Base management data port channel of the other exchange control plate on the back plate is similar.
It should be clear that the embodiments of the present invention are provided with general purpose, and are only used for illustrating the implementation of the present invention, and are not used to limit the protection scope of the present invention. Specifically, the number of ports for managing the switch chip is not limited to 20, and the embodiment of the present invention only utilizes the number of ports of the number to facilitate the description of the implementation method of the present invention; the port 1 and the port 20 are not limited to be connected to corresponding ports of the flow test instrument, and RJ45 ports of two test tool boards can be randomly selected to be used as input and output ports of test data according to the convenience of the tested wiring condition; the VLAN number of the set port VLAN is not limited, the sequence of two ports in the same VLAN is not limited, and the ports can be flexibly selected according to the convenience of wiring;

Referring to fig. 7, the method of the present invention will be described in detail by taking a testing apparatus and a connection method for testing a Fabric service data port channel on a backplane as an example.
303, because all the ports are linked together, the port channel with the problem is difficult to judge at one time, at this time, the port used for loop circulation in the step 301 is averagely divided into two parts according to a dichotomy, which is defined as a port combination A and a port combination B, and then the port combination A is tested according to the wiring and configuration method in the step 301;
because the Fabric service data port channel of the backplane is a double star structure, the testing step only completes the backplane Fabric service data port channel led out by 1 exchange control board, and the testing step needs to repeat the process by using similar wiring and the same testing method to test the backplane Fabric service data port channel led out by another exchange control board, so that the full coverage test of the backplane Fabric service data port channel can be completed.
