[0048] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of methods and systems consistent with some aspects of the present application as detailed in the appended claims.

[0050] First, the terms involved in this application are explained:

[0051] SerDes: refers to Serializer / Deserializer, which is a circuit used to convert parallel data into serial data and convert serial data into parallel data.

[0052] DAC: Direct Attach Copper, direct attach copper cable, is a cable solution for short-distance high-speed data transmission.

[0053] In network communication, switches forward data packets between network devices to achieve efficient data transmission. The inside of the switch is connected to different ports through internal links, and the ports exchange data with external devices to achieve data forwarding. Each port of the switch usually contains one or more SerDes, and each SerDes includes multiple channels (lanes). Each channel is an independent serial data channel, which can transmit data independently, and multiple channels transmit data in parallel.

[0054] According to the design of the switch chip hardware, the channel mapping (laneswap) and polarity flip (polarity flip) of each SerDes can be configured in the software. Among them, if the channel mapping is configured correctly, it can ensure that the internal link of the port has no cross-matching errors, and the order of multiple parallel channels is correct, so as to ensure that the data can be accurately transmitted from the transmitter to the receiver; each internal link includes a pair of transceiver lines, in which the transmission line Tx (Transmit) can be used to send data, and the receiving line Rx (Receive) can be used to receive data. If the polarity flip is configured correctly, the link functions normally as a transmitter or a receiver. For an internal link, data can only be forwarded correctly when the channel mapping and polarity flip are configured correctly.

[0055] With the rapid development of data center services and the rise of artificial intelligence technology, the amount of data transmitted over the network is increasing, and the bandwidth of the single chip of the network switch switch is also increasing, resulting in an increasing density of high-speed links and more diverse configurations of switch chips. Only by correctly configuring the internal links of the switch to the port can the correct transmission of network data be guaranteed. Therefore, it is necessary to detect the internal links of the port.

[0056] Take a port consisting of 4 channels as an example. Figure 1 This is a schematic diagram of the structure of the correct configuration of the internal links of the port provided by the present application. The internal link 101 of the port 100 is configured to the channel 111, the internal link 102 is configured to the channel 112, the internal link 103 is configured to the channel 113, and the internal link 104 is configured to the channel 114. Figure 2 This is a structural diagram of the cross-mismatch of the internal links of the port provided in the present application, where the internal link 101 of port 100 is configured to channel 111, the internal link 102 is configured to channel 114, the internal link 103 is configured to channel 113, and the internal link 104 is configured to channel 112; the cross-mismatch of the internal link 102 and the internal link 104 will cause data transmission errors.

[0057] Generally, there are two methods to detect the internal link of the port. One detection method is to short-circuit the internal link of the port to be detected with a self-loopback detection module, and determine whether the internal link configuration of the port to be detected is correct by analyzing whether the data sent and received by the port to be detected is consistent. Another method is a detection method based on a test device, which uses a DAC cable or an optical module to connect the test device and the port to be detected. Each detection determines whether the data sent and received between a port to be detected and the test device are consistent, thereby determining whether the internal link configuration of the port to be detected is correct. The prior art performs a detection process every time a port is detected; and when detecting a port composed of 4 channels, at the data sending end, the data is evenly distributed to the 4 channels. The channel from which the data is sent from the sending end to the receiving end does not affect the reception of the data by the receiving end, and the cross-matching of the internal link of the port does not affect the data received by the data receiving end, resulting in the inability of the existing detection method to obtain accurate detection results of the internal link of the port.

[0058] The method provided by the present application detects the internal link of a single service port once to obtain a first detection result; then groups all service ports, and mutually tests the service ports in each group result to obtain a second detection result; then determines whether the internal link configuration of all service ports is correct based on the first detection result and the second detection result; thus, the effect of detecting the internal links of all ports can be achieved by only performing a single-port detection and a group mutual test. This solves the problem that the detection process is cumbersome and the detection efficiency is low when the prior art detects the port of the switch.

[0059] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0060] Figure 3 A flow chart of the switch port internal link detection method provided in this application, such as Figure 3 As shown, the method comprises the following steps:

[0061] S301: According to the received detection instruction, determine a reference port from multiple service ports of the switch, perform a first detection on an internal link of the reference port, and obtain a first detection result; wherein the switch includes multiple service ports.

[0062] The execution subject of the switch port internal link detection method may be an electronic device, such as a computer or other device that can complete the switch port test.

[0063] The switch to be tested exchanges data with external devices through multiple service ports, the reference port is one of the multiple service ports, and the channel mapping and polarity flipping configurations of the test device port are correct.

[0064] The internal link of the reference port is first detected using the test equipment to obtain a first detection result. The first detection result is used to determine whether data can be accurately sent and received between the reference port and the test equipment, thereby determining whether the internal link configuration of the reference port matches that of the port of the test equipment. When the channel mapping configuration and polarity flip configuration of the internal link of the reference port and the port of the test equipment match, it indicates that the internal link configuration of the reference port matches that of the port of the test equipment.

[0065] S302: Grouping multiple service ports to obtain multiple grouping results without overlap, wherein each grouping result includes two service ports; each service port is divided into two grouping results.

[0066] In this step, all service ports of the switch to be tested are grouped to obtain multiple grouping results. Each grouping result includes two service ports, and multiple grouping results do not overlap. At the same time, each service port is divided into two grouping results, so that for a service port in any grouping result, another grouping result can be found, and the other grouping result also includes the service port. Two grouping results containing the same port are cross-linked through the same service port, and then all grouping results can be cross-linked.

[0067] S303: Use the two service ports of each grouping result to perform link mutual testing to obtain a second testing result, wherein the second testing result includes link mutual testing results corresponding to each of the multiple grouping results.

[0068] In this step, for all the grouping results obtained in step S302, the two service ports in each grouping result are tested against each other to obtain a mutual test result. The mutual test result indicates whether the two service ports can accurately send and receive data, thereby determining whether the internal link configurations of the two service ports match.

[0069] S304: Determine detection results of internal links of multiple service ports according to the first detection result and the second detection result.

[0070] In this step, the first detection result can be used to determine whether the internal link configuration of the reference port is correct. For the second detection result, it includes a link mutual detection result of a first grouping result, which is a link mutual detection result between the reference port and a service port X. The link mutual detection result can determine whether the internal link configuration of the reference port matches that of the service port X; it also includes a link mutual detection result of a second grouping result, which is a mutual detection result between the above service port X and another service port Y, and the link mutual detection result can determine whether the internal link configuration of the service port X matches that of the service port Y; similarly, it can be determined whether the internal link configuration of the service port Y matches that of another service port Z, and so on, until it is determined whether the internal link configuration of the two service ports in all grouping results matches. Since the reference port has been detected by the detection device, the detection result of the internal link of the reference port can be used as a reference detection result. In addition, since multiple grouping results have cross-relationships, the detection results of all other service ports can be determined from the detection result of the reference port.

[0071] The switch port internal link detection method provided in the embodiment of the present application selects a reference port, performs a detection on the internal link of the reference port, and obtains a first detection result; then all service ports are grouped, and the service ports in each group result are mutually tested to obtain multiple second detection results; then, based on the first detection result and the second detection result, it is determined whether the internal link configuration of all service ports is correct; thereby achieving the effect of detecting the internal links of all service ports by only performing one single-port detection and one group mutual test.

[0072] The method for detecting the internal link of a switch port provided in the embodiment of the present application is applicable to switches with various common ports. The switch port can be a port composed of 1 channel, a port composed of 2 channels, a port composed of 4 channels, or a port composed of 8 channels.

[0073] The following takes the case where the port of the switch to be tested is a port composed of 4 channels as an example to further illustrate the implementation of the switch port internal link detection method of the present application.

[0074] The maximum bandwidth of the switch to be tested is 51.2TB / s. The chip used in the system has 64 SerDes, each SerDes includes 8 channels, a total of 512 channels are extended, and every 4 channels form a service port, a total of 128 service ports.

[0075] Before the first and second tests, the data transmission rates of all service port channels can be reduced. Because the correctness of the internal link configuration of the switch port to be tested has nothing to do with the data transmission rate of the switch port channel, in order to save bandwidth and facilitate testing, the channels of all service ports can be reduced so that the data transmission rate of a single channel of the service port is the same as the data transmission rate supported by the test equipment. Specifically, the data transmission rate of the service port channel can be reduced to 100G or 200G.

[0076] In a specific implementation manner, performing a first detection on an internal link of a reference port to determine a first detection result includes:

[0077] First, according to a preset splitting rule, the reference port is split to obtain a plurality of sub-ports, wherein each sub-port is connected to the test device to form a first data link;

[0078] Secondly, for each sub-port, first transceived data generated between the sub-port and the test device through the first data link is obtained;

[0079] Finally, a first detection result is determined according to the first received and sent data corresponding to each sub-port.

[0080] The selected reference port is service port 1. The preset splitting rule is to split the service port based on a single channel, that is, each split service sub-port contains a channel. Service port 1 is split into 4 service sub-ports, each service sub-port corresponds to an internal link. Use an optical module or a DAC cable to connect the reference port to the port of the test equipment, and each service sub-port is connected to the corresponding port of the test equipment to form a first data link.

[0081] The first transceived data between the service subport and the corresponding port of the test device can be generated through the first data link. That is to say, the above-mentioned execution subject sends an instruction to the service subport so that the service subport sends a first reference data message through the first data link to obtain a second reference data message received by the corresponding port of the test device; sends an instruction to the corresponding port of the test device so that the corresponding port of the test device sends a third reference data message through the first data link to obtain a fourth reference data message received by the service subport. The first reference data message, the second reference data message, the third reference data message, and the fourth reference data message constitute the first transceived data.

[0082] The above first test result is:

[0083] If the first reference data message is consistent with the second reference data message and the third reference data message is consistent with the fourth reference data message, the first detection result indicates that data can be accurately transmitted between the service subport and the corresponding port of the test device, indicating that the channel mapping configuration and polarity flip configuration of the internal link of the service subport and the corresponding port of the test device match. The internal link configuration of the port of the test device is correct, thereby determining that the internal link configuration of the service subport is also correct.

[0084] If the first reference data message is inconsistent with the second reference data message; or the third reference data message is inconsistent with the fourth reference data message, the first detection result indicates that the service subport and the corresponding port of the test device cannot transmit data correctly. If the second reference data message or the fourth reference data message cannot be obtained, it means that the polarity reversal configuration of the internal link of the service subport is abnormal, resulting in abnormal function as a transmitter or a receiver; if the second reference data message and the fourth reference data message are obtained, but the first reference data message is inconsistent with the second reference data message; or the third reference data message is inconsistent with the fourth reference data message, it means that the channel mapping configuration of the internal link of the service subport is abnormal, resulting in cross-matching errors with the internal links of other service subports.

[0085] In some implementations of this embodiment, the link mutual test is performed using two service ports of each grouping result to obtain a second detection result, including the following sub-steps:

[0086] First, for each grouping result, according to the preset splitting rule, the first service port in the grouping result is split to obtain multiple first service sub-ports, and the second service port in the grouping result is split to obtain multiple second service sub-ports; wherein each first service sub-port corresponds to a second service sub-port.

[0087] The switch is still described as including 128 service ports, each of which includes 4 channels.

[0088] The above-mentioned execution entity can group the 128 service ports, and group service port 1 and service port 2 into a grouping result, service port 3 and service port 4 into a grouping result, and so on, until service port 127 and service port 128 form a grouping result; at the same time, service port 128 and service port 1 form a grouping result, service port 2 and service port 3 form a grouping result, and so on, until service port 126 and service port 127 form a grouping result, thereby completing the grouping.

[0089] For each grouping result, based on the preset splitting rule of a single channel, the first service port in the grouping result is split to obtain 4 first service sub-ports; the second service port in the grouping result is split to obtain 4 second service sub-ports; each first service sub-port corresponds to a second service sub-port. For example, for the grouping result consisting of service port 1 and service port 2, service port 1 is split into first service sub-port 11, first service sub-port 12, first service sub-port 13 and first service sub-port 14; service port 2 is split into second service sub-port 21, second service sub-port 22, second service sub-port 23 and second service sub-port 24; first service sub-port 11 corresponds to second service sub-port 21, first service sub-port 12 corresponds to second service sub-port 22, first service sub-port 13 corresponds to second service sub-port 23, and first service sub-port 14 corresponds to second service sub-port 24.

[0090] Secondly, a second data link is established between each first service subport and the corresponding second service subport. The second data link between each first service subport and the corresponding second service subport is established through a DAC cable. Still taking service port 1 and service port 2 as an example, Figure 4 A schematic diagram of the connection structure between the split service port 1 and the split service port 2 provided in this application. Figure 4 As shown, the first service subport 11 is connected to the second service subport 21 to form a second data link, the first service subport 12 is connected to the second service subport 22 to form a second data link, the first service subport 13 is connected to the second service subport 23 to form a second data link, and the first service subport 14 is connected to the second service subport 24 to form a second data link.

[0091] Then, for each first service sub-port, second transceiver data generated between the first service sub-port and the corresponding second service sub-port through the second data link is obtained.

[0092] Finally, the link mutual testing result corresponding to the grouping result is determined according to the second transceiver data respectively corresponding to each first service sub-port.

[0093] In some implementations of this embodiment, for each first service sub-port, obtaining second transceived data between the first service sub-port and the corresponding second service sub-port generated through the second data link includes the following sub-steps:

[0094] First, for each first service subport, an instruction is sent to the first service subport so that the first service subport sends a first data message to the corresponding second service subport through the second data link, and obtains a second data message received by the corresponding second service subport.

[0095] For any first service sub-port, the execution subject may send an instruction to the first service sub-port so that the first service sub-port sends a first data message through the second data link; the execution subject may receive a second data message received by the corresponding second service sub-port.

[0096] Secondly, an instruction is sent to the corresponding second service subport so that the corresponding second service subport sends a third data message to the first service subport through the second data link; and a fourth data message received by the first service subport is acquired.

[0097] The execution subject may send an instruction to the corresponding second service sub-port so that the corresponding second service sub-port sends the third data message through the second data link; the execution subject may receive the fourth data message received by the first service sub-port.

[0098] In some implementations of this embodiment, the above-mentioned determining the link mutual testing result corresponding to the grouping result according to the second transceiver data corresponding to each first service sub-port respectively includes: determining the link mutual testing result according to the first data packet, the second data packet, the third data packet and the fourth data packet.

[0099] In some implementations of this embodiment, the determining the link mutual testing result according to the first data packet, the second data packet, the third data packet, and the fourth data packet includes:

[0100] If the first data message is consistent with the second data message and the third data message is consistent with the fourth data message, there is no abnormality between the internal link of the second service sub-port and the internal link of the first service sub-port; the mutual test result indicates that data can be accurately transmitted between the first service sub-port and the corresponding second service sub-port, indicating that the configuration of the internal link of the first service sub-port matches the configuration of the internal link of the corresponding second service sub-port.

[0101] If the first data message is inconsistent with the second data message, or the third data message is inconsistent with the fourth data message, the internal link of the first service subport or the internal link of the second service subport is abnormal, and the mutual test result indicates that the first service subport and the corresponding second service subport cannot transmit data correctly. If the second data message or the fourth data message cannot be obtained, it means that the polarity flip configuration of the internal link of the first service subport and the corresponding second service subport does not match, resulting in data failure; if the second data message and the fourth data message are obtained, but the first data message is inconsistent with the second message, or the third data message is inconsistent with the fourth data message, it means that the channel mapping configuration of the internal link of the first service subport and the corresponding second service subport does not match, resulting in a cross-matching error between the internal link of the first service subport or the corresponding second service subport and other service subports.

[0102] In some implementations of this embodiment, determining link detection results of multiple service ports according to the first detection result and the second detection result includes:

[0103] If the first detection result indicates that the internal link of the reference port is normal, and the second detection result indicates that the internal link mutual testing results of the multiple grouping results are normal, it is determined that the internal links of the multiple service ports are normal.

[0104] The first detection result indicates that there is no abnormality in the internal link of the reference port, which means that it is determined that the internal link configuration of the reference port is correct.

[0105] The second detection result indicates that there is no abnormality in the internal link mutual test results of multiple grouping results, that is, for any grouping result, its mutual test result indicates that the configuration of the internal link of the first service port and the second service port in the grouping result matches. Specifically, it is manifested as: the internal link configuration of any first service sub-port of the first service port of the grouping result matches the second service sub-port of the corresponding second service port. The grouping result composed of service port 1 as the first service port and service port 2 as the second service port is still used as an example for explanation. When the first data message sent by the first business subport 11 is consistent with the second data message received by the second business subport 21; and the third data message sent by the second business subport 21 is consistent with the fourth data message received by the first business subport 11, and the first data message sent by the first business subport 12 is consistent with the second data message received by the second business subport 22; and the third data message sent by the second business subport 22 is consistent with the fourth data message received by the first business subport 12, and the first data message sent by the first business subport 13 is consistent with the second data message received by the second business subport 23; and the third data message sent by the second business subport 23 is consistent with the fourth data message received by the first business subport 13, and the first data message sent by the first business subport 14 is consistent with the second data message received by the second business subport 24; and the third data message sent by the second business subport 24 is consistent with the fourth data message received by the first business subport 14, it can be determined that the internal link configurations of business port 1 and business port 2 match.

[0106] Regarding the above-mentioned determination that there is no abnormality in the internal links of multiple service ports, a grouping result is obtained by service port 1 and service port 2, and the second detection result can be obtained that the internal link configurations of service port 1 and service port 2 match; because service port 1 is a reference port, the internal link configuration of the reference port is correct, thereby determining that the internal link configuration of service port 2 is correct; a grouping result is obtained by service port 2 and service port 3, and the second detection result can be obtained that the internal link configurations of service port 2 and service port 3 match, because the internal link configuration of service port 2 is correct, thereby determining that the internal link configuration of service port 3 is correct; and so on, service port 3 determines that the internal link configuration of service port 4 is correct, until service port 127 determines that the internal link configuration of service port 128 is correct, thereby determining that the internal link configurations of all service ports are correct.

[0107] Otherwise, the internal links of the multiple service ports are abnormal. If the first detection result indicates that the internal link of the reference port is abnormal, or the second detection result indicates that the internal links of the multiple service ports are abnormal, a first abnormal prompt message is issued to prompt the reference port or the service ports in the multiple grouping results to be corrected.

[0108] The switch port internal link detection method provided in the embodiment of the present application realizes accurate detection of the internal link of the service port by splitting all service ports based on the preset splitting rule of a single channel; obtains a first detection result by performing a single detection on the internal link of the reference port; then groups all service ports, and mutually tests the service ports in each grouping result to obtain a second detection result; then determines whether the internal link configuration of all service ports is correct based on the first detection result and the second detection result; thereby achieving accurate detection of the internal link of the service port while simplifying the detection process of the switch port internal link and improving the detection efficiency of the switch port internal link.
