Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings.

It should be noted that, in the present application, the term "and/or" is merely an association relationship describing the association object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. The terms first and second and the like in the description and in the claims of embodiments of the application, are used for distinguishing between different objects and not necessarily for describing a particular sequential order of objects. For example, the first identification information and the second identification information, etc., are used to distinguish different identification information from each other, and are not used to describe a specific order of the target object. In embodiments of the application, words such as "exemplary," "for example," or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described as "exemplary," "by way of example," or "such as" in embodiments of the application should not be construed as advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion. In the description of the embodiments of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more.

In the current solution of the whole cabinet server, because the network ports inside the server of the whole cabinet server are more, the situation that the plug is misplaced in the network ports may occur. Once the plug is plugged into the wrong network port, the upper layer service error can be caused. Therefore, how to detect the plug of the misplaced network port becomes a technical problem to be solved by the embodiment of the application.

To solve the above technical problem, in one possible implementation, a production installer is instructed to insert a plurality of plugs into respective network ports by adding tags at the plugs and at the network ports, etc.

However, in this possible implementation, only the manual identification tag can be relied on to plug the plurality of plugs into the corresponding network ports respectively, so that the plug of the misplaced network port cannot be actively detected; the alarm can not be given after the plug is misplaced in the network port, and the misplug information can not be indicated; reliability depends on the quality of manually plugging multiple plugs into the corresponding network ports.

In order to solve the above technical problem, in another possible implementation, a service environment of the whole cabinet server is constructed, and a test is performed by a function of a service layer to identify a plug of a misplaced network port. As shown in fig. 1, the test equipment is interconnected with switches a-F. In one possible implementation, switches A-F are predefined to be interconnected with the network ports ETH0-5, respectively, through a cable backplane. That is, when detecting whether a plug is plugged into a wrong network port, it is only necessary to detect whether a network message received by a certain switch comes from a predefined ETH interconnected with the switch. If yes, determining that the plug is not plugged into the wrong network port. If not, determining that the plug is misplaced in the network port.

However, in such a possible implementation, a test environment for the service layer needs to be set up, the service test is performed by the test equipment, the test environment is complex, the requirement on the test equipment is high, and the test workload is large.

Therefore, in order to solve the above technical problems, an embodiment of the present application provides a socket detection method. For easy understanding, the application scenario of the embodiment of the present application is first briefly described.

The second connector may be, for example, an SFP plug, and its memory may be, for example, a charged erasable programmable read-Only memory (EEPROM) for information storage. The first identification information of the second connector is stored in a memory thereof. As shown in fig. 4a, the first identification information stored in the memory of the second connector is 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, respectively. In one example, the first identification information of the SFP plug may be a custom manufacturer Serial Number (SN), and stored in its EEPROM.

In method 500, each of a plurality of second connectors in a cable module located on server 220 is connected to a respective one of a plurality of portals. The plurality of second connectors are connected to the cable back plate 240 through the first connector L1 in the cable module located on the server 220. Each second connector includes a memory. It will be appreciated that each portal has a second connector corresponding to the portal, and that the portal is connected to the corresponding second connector to enable communication, and that the second connector connected to the target portal is the second connector corresponding to the target portal. The second identification information of the second connector connected with the target network port is defined, and is preset identification information stored in a memory of the second connector corresponding to the target network port. The second identification information is position identification information of the second connector. The second identification information of the plurality of second connectors has a one-to-one correspondence with the network port identification information of each network port. That is, the portal into which the second connector should be inserted can be determined by the second identification information. The target network port is one of a plurality of network ports. The flow chart of the method 500 is shown in fig. 5, including S501-S508, and the specific implementation process is as follows:

It should be noted that, the management controller 330 needs to obtain the first identification information of the target connector connected to the target portal, see the specific implementation procedure of S501-S506 described below. After acquiring the first identification information, the management controller 330 determines whether the first identification information is the same as the second identification information, and if not, determines that the target connector is misplaced in the target network port, see the specific implementation process of S507-S508 described below. The target network port is one of a plurality of network ports, the target connector is one of a plurality of second connectors, and the second identification information is preset identification information for prescribing the second connectors connected with the target network port.

S501, the management controller 330 sends a second request message to the processor 340.

The second request message is used for requesting the SN of the target SFP plug connected with the target network port.

S502, the processor 340 acquires the second request message from the management controller 330.

In an embodiment of the present application, the processor 340 obtains the second request message from the management controller 330.

S503, the processor 340 sends a third request message to the network card where the target portal is located.

In the embodiment of the present application, the processor 340 sends a third request message to the network card where the target network port is located. The third request message is used for requesting the network card where the target network port is located for first identification information of the target connector connected with the target network port.

In one example, the CPU sends a third request message to the network card where the target portal is located, so as to obtain the first identification information of the target connector connected to the target portal.

It should be noted that, after the network card obtains the third request message sent by the processor 340, the first identification information in the memory of the target connector is read through the integrated circuit bus (inter-integrated circuit, IIC).

S504, the processor 340 acquires a third response message from the network card where the target portal is located.

In the embodiment of the application, the processor acquires the third response message from the network card where the target network port is located. The third response message includes first identification information of a target connector connected with the target portal. The first identification information in the third response message is obtained from the memory of the target connector by the network card. For example, fig. 6a shows a schematic diagram in which the processor reads first identification information, such as 0x02, of a target connector connected to a target portal, such as portal 1. Fig. 6b shows the processor reading the first identification information of the second connectors connected to the six ports, respectively. Referring to fig. 6b, the first identification information of the target connector connected to the portal 1 is 0x02, the first identification information of the target connector connected to the portal 2 is 0x01, the first identification information of the target connector connected to the portal 3 is 0x03, the first identification information of the target connector connected to the portal 4 is 0x04, the first identification information of the target connector connected to the portal 5 is 0x05, and the first identification information of the target connector connected to the portal 6 is 0x06.

In an embodiment of the present application, the management controller 330 receives the second response message. That is, the management controller 330 acquires the first identification information of the target connector connected to the target portal.

In one example, the BMC receives the second response message. That is, the BMC obtains the SN of the target SFP plug connected to the target portal.

It should be noted that S501 to S506 are specific implementation processes in which the management controller 330 requests the processor 340 for the first identification information of the target connector connected to the target portal. In this embodiment of the present application, the processor 340 may also poll the management controller 330 for the first identification information after requesting the first identification information from the network card where the target network port is located.

S507, the management controller 330 determines whether the first identification information and the second identification information are identical.

It should be noted that, first, the management controller 330 may send a first request message to the processor 340. The first request message is used for requesting the network port identification information of the target network port. After receiving the first request message, the processor 340 obtains the portal identification information of the target portal. The processor 340 transmits a first response message to the management controller 330. The first response message includes portal identification information of the target portal. The management controller 330 receives the first response message from the processor 340. The management controller 330 determines the second identification information based on the portal identification information in the first response message.

In one possible implementation, the first request message may be used to request the portal identification information of the target portal and the first identification information of the target connector connected to the target portal at the same time.

It may be appreciated that the management controller 330 may determine the second identification information according to the network port identification information of the target network port and the mapping relationship table of the identification information (i.e. table 1). The identification information mapping relation table is used for representing the mapping relation between the network port identification information of the target network port and the second identification information. The second identification information of the plurality of second connectors has a one-to-one correspondence with the network port identification information of each network port. The second identification information is preset identification information for prescribing a second connector connected with the target network port.

In another embodiment, the second identification information of the plurality of second connectors is information having a one-to-one correspondence with the portal identification information of each portal, and is stored in the memory of the server. The corresponding second identification information may be retrieved from memory before the management controller 330 determines whether the first identification information is the same as the second identification information.

In an embodiment of the present application, the management controller 330 determines whether the first identification information is identical to the second identification information.

In one example, the BMC determines whether the first identification information is the same as the second identification information.

TABLE 1

Net mouth	Network port identification information	Second identification information	Second connector
				Net port 01	G1	0x01	Second connector 10
Net port 02	G2	0x02	Second connector 20
				Net port 03	G3	0x03	Second connector 30
Net port 04	G4	0x04	Second connector 40
				Net port 05	G5	0x05	Second connector 50

S508, if the first identification information is different from the second identification information, the management controller 330 determines that the target connector is misplaced in the target portal.

In the embodiment of the present application, if the first identification information is different from the second identification information, the management controller 330 determines that the target connector is misplaced in the target portal.

In one example, if the first identification information is different from the second identification information, the BMC determines that the target SFP plug is misplaced to the target portal. Compared with the target plug which relies on manual detection of the misplaced target network port, the method and the device can determine the target plug of the misplaced target network port on a software level, and reduce the complexity of detection of the target plug of the misplaced target network port.

Illustratively, table 2 shows first identification information of a target connector connected to a target portal. As can be seen from table 2, the second connector 20 is misplaced with respect to the port 01, and the second connector 10 is misplaced with respect to the port 02.

TABLE 2

Net mouth	Network port identification information	Second identification information	First identification information	Second connector
					Net port 01	G1	0x01	0x02	Second connector 20
Net port 02	G2	0x02	0x01	Second connector 10
					Net port 03	G3	0x03	0x03	Second connector 30
Net port 04	G4	0x04	0x04	Second connector 40
					Net port 05	G5	0x05	0x05	Second connector 50
Net port 06	G6	0x06	0x06	Second connector 60

It will be appreciated that referring to fig. 7, in order for the user to more intuitively see the target connectors of the misplaced target portal, an icon and a plugging identifier for each second connector may be displayed on the interface. The plug-in identification comprises an alarm identification or a normal identification. The alarm identifier is used for prompting the target connector to plug in the target network port by mistake, and the normal identifier is used for indicating the target connector to plug in the target network port. As shown in fig. 7, the interface shows that the first identification information of the second connector 20 inserted into the port 01 is 0x02, the first identification information of the second connector 10 inserted into the port 02 is 0x01, the first identification information of the second connector 30 inserted into the port 03 is 0x03, the first identification information of the second connector 40 inserted into the port 04 is 0x04, the first identification information of the second connector 50 inserted into the port 05 is 0x05, the first identification information of the second connector 60 inserted into the port 06 is 0x06, and the black circle represents the alarm mark, the second connector identifying the misplug port 01 is the second connector 20, the second connector inserting the misplug port 02 is the second connector 10, the white circle represents the normal mark, and the second connectors 30, 40, 50, 60 are respectively inserted into the ports 03, 04, 05, 06.

According to the embodiment of the application, the management controller can query preset identification information, namely second identification information, of the second connector which is specified to be connected with the target network port according to the identification information mapping relation table. If the first identification information and the second identification information of the target connector inserted into the target network port are different, the management controller determines that the target connector is inserted into the wrong target network port. Compared with the method that whether the target connector is misplaced or not is detected manually, the method and the device can determine whether the target connector is misplaced or not at a software level, and complexity of detecting whether the target connector is misplaced or not is reduced. Compared with the test environment of the service layer built and the service test performed by the test equipment, so that whether the target connector is misplaced in the target network port is detected, the embodiment of the application does not need to build the environment of the service layer, reduces the workload of the test link, does not need to rely on external test equipment, and reduces the cost of detecting whether the target connector is misplaced in the target network port.
