Description

Technical Field

[0001] This application relates to the field of network communication technology, and in particular to a method and apparatus for detecting port status consistency. Background Technology

[0002] With the continuous development and widespread application of information technology, the reliability requirements of application systems are becoming increasingly stringent. In application service reliability design, physical network redundancy design is a crucial component. In a physical network redundancy scenario, an application server is simultaneously connected to ports GE0 / 27 of both switch A and switch B. If the port configurations and states of the paired ports on switches A and B are inconsistent, the redundancy scheme may fail, leading to network failure.

[0003] Currently, when redundancy solutions fail, operations engineers need to determine the scope of network devices affected by the fault, then further determine the paired ports based on the device configuration descriptions, and finally determine whether the paired ports' statuses are consistent based on their experience. Alternatively, port speeds and other parameters could be included as monitoring items in routine automated checks. When redundancy solutions fail, operations engineers would determine the scope of network devices affected by the fault, then further determine the paired ports based on the device configuration descriptions. Based on the results of routine monitoring checks, operations engineers would query the status information of the paired ports and manually compare the consistency of their statuses.

[0004] However, when business failures occur, it takes a lot of time and effort for operations engineers to troubleshoot manually or with the help of monitoring products to locate the fault. More importantly, routine checks are not performed in advance to prevent problems from happening in the first place. Summary of the Invention

[0045] Figure 3 This is a schematic diagram of another port state consistency detection device provided in an embodiment of this application. Detailed Implementation

[0046] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The singular forms “a,” “the,” and “the” as used in this application and claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to any and all possible combinations comprising one or more of the associated listed items.

[0047] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" may also be interpreted as "when," "when," or "in response to a determination."

[0048] For example, see Figure 1 The diagram shown is a detailed flowchart of a port state consistency detection method provided in an embodiment of this application. The method includes the following steps:

[0049] Step 100: Obtain the interface information of each network device in the target network. The interface information of a network device includes the interface description information and interface configuration information of each interface of the network device.

[0050] It should be noted that, in this embodiment of the application, a preferred implementation is that the above-mentioned port status consistency detection method is executed by a detection server, and the detection server is a third-party detection device outside the network.

[0051] Of course, the detection server can also be a network device in the network that can perform the detection server function. In this embodiment of the application, no specific limitation is made here.

[0052] In this embodiment of the application, when obtaining the interface information of each network device in the target network, a preferred implementation method is to: obtain a list of network devices in the target network; based on a preset protocol, log in to each network device included in the network device list, and obtain the interface information of each network device from each network device.

[0053] Preferably, the preset protocol is Secure Shell Protocol (SSH) or Telnet. Accordingly, in this embodiment, the usernames and passwords corresponding to each network device in the target network can be pre-configured on the device used for port status consistency detection, wherein the username and password corresponding to one network device are used to log in to that network device.

[0054] Therefore, when logging into each network device in the network device list based on a preset protocol, a preferred implementation is to log into the corresponding network device using the username and password corresponding to each network device based on the SSH / Telnet protocol.

[0055] For example, on the detection server, username 1 and password 1 are pre-set for network device 1, username 2 and password 2 for network device 2, ..., username n and password n ​​for network device n. Then, when logging into network device 1, username 1 and password 1 are used based on the SSH / Telnet protocol. Similarly, when logging into network device m, username m and password m are used based on the SSH / Telnet protocol.

[0056] Next, the detection server obtains the interface information of each logged-in network device.

[0057] In this embodiment of the application, the interface information of a network device includes the interface description information and interface configuration information of each interface of the network device. Specifically, if an interface belongs to a redundant paired port group, the interface description information of the interface includes at least the interface identifier of the interface and the interface identifiers of other peer interfaces that form a redundant paired port group with the interface; the interface configuration information of the interface includes at least MTU, simplex mode, working mode, port speed, negotiation speed, IP subnet and VLAN configuration.

[0058] After logging into each network device, the detection server can obtain the interface information of each interface included in each network device.

[0059] In this embodiment, the detection server can periodically obtain device interface information from various network devices. For example, the preset period is 1 day, and the server obtains device interface information from various network devices at 2:00 AM every day. Specifically, the preset period length can be set based on user needs and / or different application scenarios, and is not specifically limited in this embodiment.

[0060] Step 110: Based on the interface description information of each interface of each network device, identify redundant paired port groups.

[0061] In this embodiment of the application, after the detection server obtains the interface information of each network device, it can identify and determine each interface belonging to the redundant pairing port based on the interface description information of each interface. Furthermore, it can also identify each redundant pairing port group.

[0062] The interface description information for each interface includes the interface's identifier, the device identifier to which the interface belongs, the identifiers of other peer interfaces belonging to the same redundant paired port group, and the device identifiers of those peer interfaces. Based on this information, it is possible to determine which interfaces form a redundant paired port group, thus identifying multiple redundant paired port groups.

[0063] For example, if the interface description information of interface 11 includes the identifier of interface 11, and the other peer interface that forms a redundant paired port group with interface 11 is interface 12, then it can be identified that interface 11 and interface 12 are a redundant paired port group.

[0064] Step 120: For each identified redundant paired port group, based on the interface configuration information of each interface included in the redundant paired port group, check whether the interface status of each interface included in the redundant paired port group is consistent.

[0065] As can be seen from the above, the interface configuration information of each interface belonging to the redundant paired port group includes at least MTU, simplex / duplex mode, working mode, port speed, negotiation speed, IP subnet and VLAN configuration.

[0066] Therefore, when detecting whether the interface status of each interface in the redundant paired port group is consistent based on the interface configuration information of each interface in the redundant paired port group, a better implementation method is to detect whether the MTU, simplex mode, working mode, port speed, negotiation speed, IP subnet and VLAN configuration of each interface in the redundant paired port group are consistent.

[0067] If the status of all interfaces in a redundant paired port group is consistent, the redundant paired port group is considered to be in normal status; otherwise, the redundant paired port group is considered to be in abnormal status.

[0068] At this point, an alarm message can be issued to prompt the operations and maintenance engineer to handle the faulty redundant port group in an abnormal state.

[0072] The detection unit 22 is used to detect whether the interface status of each interface included in the redundant paired port group is consistent based on the interface configuration information of each interface included in the redundant paired port group.
