Description

Technical Field

[0001] The present application relates to the field of network communication technology, and in particular to a method and system for checking the consistency of a cross-device link aggregation group configuration. Background Art

[0002] In the current deployment of Multi-Chassis Link Aggregation Group (M-LAG) systems, configuration consistency check is a key step to ensure that two M-LAG devices can correctly collaborate and forward messages. This process is usually implemented by exchanging configuration information through peer-link links, which are divided into two categories for checking: critical configuration and general configuration. Critical configuration directly affects the forwarding function of the M-LAG system. If it does not match, the M-LAG interface on the device will be set to the down state, which may cause problems such as normal link status but long-term packet loss. General configuration mainly affects the function of the service module. Although it does not affect the overall operation of the M-LAG system when it does not match, it may weaken the performance of specific services.

[0003] Currently, the consistency check of M-LAG configuration is mainly performed manually, but due to the low accuracy of this method, it cannot ensure that the configurations of the devices at both ends of the M-LAG are completely consistent. Therefore, how to improve the accuracy of the consistency check of the cross-device link aggregation group configuration is a problem that still needs to be solved.

[0054] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0055] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0056] The main solution of the present application is to receive a configuration consistency check message from a device sending a cross-device link aggregation group to obtain target configuration information; obtain local configuration information, and compare the local configuration information with the target configuration information; when the local configuration information is inconsistent with the target configuration information, perform configuration synchronization according to the target configuration information.

[0057] Currently, the consistency check of M-LAG configuration is mainly performed manually, but due to the low accuracy of this method, it cannot ensure that the configurations of the devices at both ends of the M-LAG are completely consistent. Therefore, how to improve the accuracy of the consistency check of the cross-device link aggregation group configuration is a problem that still needs to be solved.

[0058] This application automatically performs configuration consistency check and configuration synchronization of devices in a cross-device link aggregation group by configuring consistency check messages, thereby improving the accuracy of consistency check of cross-device link aggregation group configurations.

[0059] Based on this, the embodiment of the present application provides a method for checking the consistency of the cross-device link aggregation group configuration, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the consistency check method for cross-device link aggregation group configuration of the present application.

[0060] In this embodiment, the method for checking the consistency of the cross-device link aggregation group configuration includes steps S10 to S30:

[0061] Step S10: receiving a configuration consistency check message from a device sending a cross-device link aggregation group to obtain target configuration information;

[0062] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a consistency check receiving device configured in a cross-device link aggregation group, etc. The following takes the consistency check receiving device configured in a cross-device link aggregation group as an example to illustrate this embodiment.

[0063] It should be noted that the inter-device link aggregation group is M-LAG, and the configuration consistency check message includes the configuration summary information of the M-LAG sending device.

[0064] In a feasible manner, before the step of receiving a configuration consistency check message from a device sending a cross-device link aggregation group to obtain target configuration information, the step further includes:

[0065] Get the data fields stored in the configuration structure;

[0066] According to the data field, the configuration synchronization function is enabled or disabled.

[0067] It should be noted that the configuration structure is a common data organization method used to store and manage the configuration information of a program or system. The data field is check_auto-config. When the m-lag auto-config-syncenable command is executed, the system will indicate in this field that the automatic configuration synchronization function has been enabled. Among them, the m-lag auto-config-sync enable command is a newly added command used to enable the automatic configuration synchronization function, and correspondingly, the m-lagauto-config-sync disable command is used to disable the automatic configuration synchronization function.

[0068] In a feasible manner, the step of receiving a configuration consistency check message from a device sending a cross-device link aggregation group to obtain target configuration information includes:

[0069] Receive messages from the sending device in the cross-device link aggregation group;

[0070] The type of the message is identified, and a configuration consistency check message is determined according to the type to obtain target configuration information.

[0071] It is understandable that the messages from the device sending the cross-device link aggregation group include not only configuration consistency check messages, but also messages with other information, so it is necessary to identify the type of the message, and the type of the configuration consistency check message is the M-LAG protocol message, so when the M-LAG protocol message is identified, it can be determined that it is a configuration consistency check message, wherein the identification process is performed by the hardware support layer (Hardware support layer, hsl).

[0072] Step S20: Acquire local configuration information, and compare the local configuration information with the target configuration information;

[0073] It is understandable that the local configuration information should be the same as the target configuration information, so by comparing the local configuration information with the target configuration information, the configuration consistency of the M-LAG can be determined.

[0074] In a feasible manner, after the step of obtaining the local configuration information and comparing the local configuration information with the target configuration information, the method further includes:

[0075] When the local configuration information is inconsistent with the target configuration information, determining whether configuration synchronization can be performed;

[0076] If configuration synchronization is not possible, a warning message is generated.

[0077] It is understandable that when the local configuration information is too far away from the target configuration information, configuration synchronization may fail, so it is necessary to determine whether configuration synchronization is possible. When the local configuration information is too far away from the target configuration information, a warning message needs to be generated to remind the administrator to intervene in time.

[0078] Step S30: When the local configuration information is inconsistent with the target configuration information, configuration synchronization is performed according to the target configuration information.

[0079] It should be noted that when the local configuration information is inconsistent with the target configuration information, configuration synchronization needs to be performed according to the target configuration information. The local device will automatically learn the corresponding configuration in the sending device and apply these configurations on the local device to achieve configuration synchronization.

[0080] In a feasible manner, before the step of performing configuration synchronization according to the target configuration information, the method further includes:

[0081] Encapsulating the target configuration information to obtain a data packet;

[0082] Sending the data packet to a network protocol device so that the network protocol device performs compatibility checking and verification;

[0083] Receive feedback information from the network protocol device, and determine a configuration strategy according to the feedback information.

[0084] It should be noted that before configuration synchronization, the target configuration information needs to be encapsulated and sent to the network protocol device, and the network protocol refers to the Multiple Spanning Tree Protocol (MSTP), Link Aggregation Control Protocol (LACP) and other protocols. The purpose is to ensure that the configured value is within the legal range and will not affect the normal coordination of MLAG and other network protocols. Feedback information includes the compatibility after configuration synchronization. According to the feedback information, the configuration strategy can be determined. When the compatibility does not meet the requirements, configuration synchronization will not be performed; when the compatibility meets the requirements, configuration synchronization will be performed.

[0085] In a feasible manner, when the local configuration information is inconsistent with the target configuration information, the step of performing configuration synchronization according to the target configuration information includes:

[0086] When the local configuration information is inconsistent with the target configuration information, checking whether the configuration synchronization function is enabled;

[0087] When the configuration synchronization function is in an enabled state, configuration synchronization is performed according to the target configuration information.

[0088] When it is detected that the local configuration information is inconsistent with the target configuration information, it is necessary to detect whether the configuration synchronization function is enabled. Only when the configuration synchronization function is enabled can configuration synchronization be performed, in order to ensure that the configuration synchronization of MLAG is within a controllable range.

[0089] In a feasible manner, after the step of performing configuration synchronization according to the target configuration information, the method further includes:

[0090] Collect data information during configuration synchronization;

[0091] Generate a log report based on the data information.

[0092] It should be noted that the data information during configuration synchronization includes the modified configuration items, modification time, etc. Based on this information, a log report will be generated, which will record the results of configuration synchronization. When configuration synchronization fails, a warning message will also be generated to remind the administrator to solve it.

[0093] This embodiment receives a configuration consistency check message from a device sending a cross-device link aggregation group to obtain target configuration information; obtains local configuration information, and compares the local configuration information with the target configuration information; when the local configuration information is inconsistent with the target configuration information, performs configuration synchronization according to the target configuration information.

[0094] In summary, the present application improves the accuracy of the consistency check of the cross-device link aggregation group configuration by automatically performing configuration consistency check and configuration synchronization of the cross-device link aggregation group devices through receiving configuration consistency check messages.

[0095] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the consistency check method for cross-device link aggregation group configuration of the present application.

[0096] In this embodiment, the method for checking the consistency of the cross-device link aggregation group configuration includes steps S100 to S200:

[0097] Step S100: obtaining a preset time interval, and periodically generating a configuration consistency check message according to the preset time interval;

[0098] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a consistency check sending device configured in a cross-device link aggregation group, etc. The following takes the consistency check sending device configured in a cross-device link aggregation group as an example to illustrate this embodiment.

[0099] It should be noted that the preset time interval is set by the user. A timer is set inside the sending device. If the time interval is 10 minutes, the configuration consistency check will be triggered every 10 minutes. The sending device will obtain the configuration summary information and generate a configuration consistency check message.

[0100] Step S200: Send the configuration consistency check message to a receiving device in an inter-device link aggregation group.

[0101] It should be noted that when a configuration consistency check message is generated, the configuration consistency check message will be sent to a receiving device in the cross-device link aggregation group.

[0102] This embodiment obtains a preset time interval, periodically generates a configuration consistency check message according to the preset time interval, and sends the configuration consistency check message to a receiving device of a cross-device link aggregation group. This can ensure a regular configuration consistency check, timely discover configuration inconsistencies, and improve the accuracy of the consistency check of the cross-device link aggregation group configuration.

[0103] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. Figure 3 , Figure 3 This is a flow chart of the third embodiment of the method for checking the consistency of the cross-device link aggregation group configuration of the present application.

[0104] In this embodiment, the method for checking the consistency of the cross-device link aggregation group configuration includes steps S01 to S03:

[0105] Step S01: receiving a data packet from a receiving device in an inter-device link aggregation group;

[0106] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a network protocol device, etc. The following takes a network protocol device as an example to illustrate this embodiment.

[0107] It is understandable that the data packet contains relevant information for configuration synchronization of the receiving device of the cross-device link aggregation group. Through the data packet, the configuration information that needs to be modified by the receiving device of the cross-device link aggregation group can be obtained.

[0108] Step S02: performing compatibility check and verification according to the data packet and generating feedback information;

[0109] It should be noted that compatibility checking and verification is to ensure that the configured value is within the legal range and will not affect the normal cooperation between MLAG and other network protocols. Feedback information includes the compatibility after configuration synchronization.

[0110] Step S03: Send the feedback information to a receiving device in the inter-device link aggregation group.

[0111] It is understandable that by sending the feedback information to the receiving device of the inter-device link aggregation group, the receiving device can determine the configuration strategy according to the feedback information and decide whether to perform configuration synchronization.

[0112] This embodiment receives a data packet from a cross-device link aggregation group receiving device; performs compatibility check and verification based on the data packet, generates feedback information; and sends the feedback information to the cross-device link aggregation group receiving device. The compatibility of the content of configuration synchronization is verified, ensuring that the configuration synchronization will not affect the normal coordination of MLAG and other network protocols, and improving the accuracy of the consistency check of the cross-device link aggregation group configuration.

[0113] For example, in order to help understand the implementation process of the consistency check method for cross-device link aggregation group configuration obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 4 , Figure 4 A brief flowchart of a method for checking the consistency of a cross-device link aggregation group configuration is provided. Specifically:

[0114] HW (Hardware) receives the configuration consistency check packet from the peer M-LAG device; HSL (Hardware support layer) distinguishes the message type and identifies the M-LAG protocol message; M-LAG then analyzes whether the key configuration and general configuration are consistent. If they are inconsistent and automatic configuration is enabled, it synchronizes the configuration. It also sends configuration messages to MTS, LAC and other protocols, and receives feedback results.

[0115] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the consistency check method for cross-device link aggregation group configuration of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0116] This application also provides a consistency check device for cross-device link aggregation group configuration, please refer to Figure 5 , the consistency checking device for cross-device link aggregation group configuration includes:

[0117] A receiving module 10 is used to receive a configuration consistency check message from a sending device of a cross-device link aggregation group to obtain target configuration information;

[0118] A comparison module 20, configured to obtain local configuration information and compare the local configuration information with the target configuration information;

[0119] The synchronization module 30 is used to perform configuration synchronization according to the target configuration information when the local configuration information is inconsistent with the target configuration information.

[0120] This embodiment receives a configuration consistency check message from a device sending a cross-device link aggregation group to obtain target configuration information; obtains local configuration information, and compares the local configuration information with the target configuration information; when the local configuration information is inconsistent with the target configuration information, performs configuration synchronization according to the target configuration information.

[0121] In summary, the present application improves the accuracy of the consistency check of the cross-device link aggregation group configuration by automatically performing configuration consistency check and configuration synchronization of the cross-device link aggregation group devices through receiving configuration consistency check messages.

[0122] In one embodiment, the receiving module 10 is further used to obtain a data field stored in the configuration structure; and enable or disable the configuration synchronization function according to the data field.

[0123] In one embodiment, the receiving module 10 is further used to receive a message from a sending device in an inter-device link aggregation group; identify the type of the message, and determine a configuration consistency check message according to the type.

[0124] In one embodiment, the comparison module 20 is further used to determine whether configuration synchronization can be performed when the local configuration information is inconsistent with the target configuration information; if configuration synchronization cannot be performed, generate a warning message.

[0125] In one embodiment, the synchronization module 30 is also used to encapsulate the target configuration information to obtain a data packet; send the data packet to a network protocol device so that the network protocol device performs a compatibility check and verification; receive feedback information from the network protocol device, and determine a configuration strategy based on the feedback information.

[0126] In one embodiment, the synchronization module 30 is further used to check whether a configuration synchronization function is enabled when the local configuration information is inconsistent with the target configuration information; when the configuration synchronization function is enabled, perform configuration synchronization according to the target configuration information.

[0127] In one embodiment, the synchronization module 30 is further used to collect data information during configuration synchronization; and generate a log report based on the data information.
