Description

Technical Field

[0001] The present invention relates to the field of computer network communication technology, and in particular to a cross-device link aggregation group registration method, device, equipment and medium. Background Art

[0002] MC-LAG (Multichassis Link Aggregation Group) is a mechanism for implementing cross-device link aggregation. It improves the reliability of the link from the single-board level to the device level by performing cross-device link aggregation between two connected switches and user-side devices or servers in the same state. At the same time, since MC-LAG devices can be upgraded separately, the stability of service traffic is guaranteed.

[0003] During the registration process of the cross-device link aggregation group, maintenance personnel are required to manually configure to maintain the network. Therefore, the current registration method of the cross-device link aggregation group is suitable for the case where the maintenance personnel are familiar with the switch manual and execute the configuration commands. Moreover, for different types of switches, the execution commands are also different, which places high demands on the maintenance personnel. Secondly, there are many configuration commands for the cross-device link aggregation group, and the on-site deployment personnel need to constantly check and verify the configuration. Therefore, manually completing the registration of the cross-device link aggregation group is inefficient and complex.

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] MC-LAG is a mechanism for implementing cross-device link aggregation. It improves the reliability of the link from the single-board level to the device level by performing cross-device link aggregation between two connected switches and the user-side device or server in the same state. At the same time, since MC-LAG devices can be upgraded separately, the stability of service traffic is guaranteed.

[0059] During the registration process of the cross-device link aggregation group, maintenance personnel are required to manually configure to maintain the network. Therefore, the current registration method of the cross-device link aggregation group is suitable for the case where the maintenance personnel are familiar with the switch manual and execute the configuration commands. Moreover, for different types of switches, the execution commands are also different, which places high demands on the maintenance personnel. Secondly, there are many configuration commands for the cross-device link aggregation group, and the on-site deployment personnel need to constantly check and verify the configuration. Therefore, manually completing the registration of the cross-device link aggregation group is inefficient and complex.

[0060] The terms "including" and "having" in the specification of the present invention and the above-mentioned drawings, as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may include steps or units that are not listed.

[0061] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0062] See also Figure 1 As shown, the embodiment of the present application discloses a cross-device link aggregation group registration method, including:

[0063] Step S11: Sending a preset automatic registration instruction of the inter-device link aggregation group to each switch in the inter-device link aggregation group, so as to restart each of the switches.

[0064] In this embodiment, the preset automatic registration instruction of the cross-device link aggregation group is sent to each switch in the cross-device link aggregation group so that each switch can be restarted, including: when receiving the preset automatic registration instruction of the cross-device link aggregation group, clearing the configuration information related to the registration of the cross-device link aggregation group; sending the preset automatic registration instruction to each switch so that each switch can be restarted.

[0065] When the system receives a preset automatic registration instruction for a cross-device link aggregation group sent by a user, the system can automatically complete the registration of the cross-device link aggregation group according to the preset automatic registration instruction, wherein the system can specifically be a zero touch provisioning server (Zero Touch Provisioning Server, i.e., ztp server), that is, when the zero touch provisioning server receives the preset automatic registration instruction for the cross-device link aggregation group, it clears the configuration information related to the registration of the cross-device link aggregation group, and sends the preset automatic registration instruction to each switch so that each switch can be restarted; the zero touch provisioning server completes the registration of the cross-device link aggregation group without cumbersome manual configuration steps, greatly reducing the time and manpower investment required for configuration. Manual configuration is prone to human errors, while zero touch configuration can effectively avoid such errors, ensure the accuracy and consistency of configuration, and can be integrated with an automated operation and maintenance management system to facilitate centralized management and monitoring. Moreover, when a new device joins the network, the link aggregation group registration can be easily completed, facilitating network expansion and upgrade. It is understandable that if the user does not issue the preset automatic registration instruction for the cross-device link aggregation group, but issues the preset manual registration instruction, then the system can also support users to manually register, with multiple registration modes, making the registration of the cross-device link aggregation group more flexible.

[0066] Step S12: If the configuration information related to the registration of the cross-device link aggregation group does not exist in each of the switches, the port status of each of the switches is determined; if the port status of each of the switches is in the open state, the messages between the switches are controlled.

[0067] If there is no configuration information related to the registration of the cross-device link aggregation group in each switch, it means that the cross-device link aggregation group registration is not currently being performed. Therefore, the automatic registration process can be executed, that is, the port status of each switch is determined. If the port status of each switch is open (that is, up), it means that the switch message interaction can be performed at this time, so the system controls the message interaction between each switch, that is, the switch sends message information to other switches, and also receives message information sent by other switches.

[0068] In this embodiment, it also includes: if the port status of each of the switches is an abnormal state, it is determined that the current registration process is blocked; wherein the abnormal state includes a port link interruption state and a port link disconnection state; waiting for the port status of each of the switches to be converted from the abnormal state to the open state, so as to execute the step of controlling the message interaction between each of the switches. If the port status of each switch is an abnormal state, that is, the port status is a port link interruption state, a port link disconnection state or other abnormal state, it means that the registration process is blocked and message interaction cannot be performed. Only by waiting for the port status of each switch to be converted from the abnormal state to the open state can the switch be controlled to perform message interaction.

[0069] Step S13: Control the exchange of device information between the switches based on the received message information, so that each switch uses the device information to configure the target session port of the cross-device link aggregation group and establish the session of the cross-device link aggregation group, thereby completing the registration of the cross-device link aggregation group.

[0070] In this embodiment, the control of the exchange of device information between the switches based on the received message information includes: controlling the switches to select corresponding device information from the system media access control address, version number, and device port based on the received message information, and controlling the exchange of device information between the switches. The system controls the switches to exchange device information based on the received message information, wherein the device information may include any one or more interactive information of the system media access control address (system-mac, i.e., system-Media Access Control Address), version number, and device port, and controls the exchange of device information between the switches; further, the system also monitors whether the exchange of device information is completed, and if not, it is necessary to continue to execute the exchange of device information, and if completed, it starts the subsequent related configuration and session establishment.

[0071] In this embodiment, each of the switches uses the device information to configure the target session port of the cross-device link aggregation group and establish a session of the cross-device link aggregation group, including: each of the switches uses the device information to configure the direct-connected Layer 2 link interface, and adds the first target virtual LAN corresponding to the direct-connected Layer 2 link interface to the direct-connected Layer 2 link interface; each of the switches uses the device information to identify its own device address, and uses the device address to establish a session of the cross-device link aggregation group, so as to synchronize the media access control address table entries between each of the switches using the session of the cross-device link aggregation group and the direct-connected Layer 2 link interface. Each switch configures the direct-connected Layer 2 link (peer-link) interface using the device information, and adds the first target virtual local area network (Virtual Local Area Network, i.e., VLAN) corresponding to the direct-connected Layer 2 link interface to the direct-connected Layer 2 link interface; each switch identifies its own device address (Internet Protocol, i.e., IP) using the device information, and uses the device address to establish a session of an inter-device link aggregation group, so as to synchronize the media access control address table entries between each switch using the session of the inter-device link aggregation group and the direct-connected Layer 2 link interface.

[0072] Furthermore, for the direct-connected Layer 2 link interface, because the direct-connected Layer 2 link interface carries a large amount of data after synchronization information or flooding traffic reaches the direct-connected Layer 2 link interface, the direct-connected Layer 2 link interface will use dynamic link aggregation to automatically expand to dual-link redundant backup to ensure the reliability of the service port.

[0073] In this embodiment, the process in which each of the switches configures the target session port of the cross-device link aggregation group using the device information and establishes the session of the cross-device link aggregation group also includes: each of the switches determines its own role using the system media access control address in the device information; wherein the role is a master switch or a backup switch. Each switch determines its own role using the system media access control address in the device information, that is, each switch determines whether it is a master switch or a backup switch, that is, the master and backup roles are automatically elected between devices.

[0074] In this embodiment, each of the switches configures the target session port of the cross-device link aggregation group using the device information, including: each of the switches configures the multi-active mechanism detection interface using the device information, and uses the multi-active mechanism detection interface to detect the state of the cross-device link aggregation group between the master switch and the standby switch, obtains the state detection result, generates configuration information including the state detection result and related to the registration of the cross-device link aggregation group, and sends the configuration information to the database of each of the switches. Each switch configures the multi-active mechanism detection (MAD) interface using the device information, and uses the multi-active mechanism detection interface to detect the state of the cross-device link aggregation group between the master switch and the standby switch. The multi-active mechanism detection interface is mainly used to detect whether a negotiation abnormality occurs between the master and standby devices, that is, the dual machine role is the master, or the dual machine role is the standby, obtains the state detection result, and then generates the configuration information including the state detection result and related to the registration of the cross-device link aggregation group, and sends the configuration information to the database of each switch.

[0075] In this embodiment, after each of the switches configures the target session port of the cross-device link aggregation group using the device information and establishes the session of the cross-device link aggregation group, it also includes: each of the switches adds the second target virtual LAN corresponding to the non-target session port to the non-target session port, and adds the non-target session port to the cross-device link aggregation group member to configure link redundancy backup; when the role of each of the switches is switched, the link redundancy backup is started. The master and standby devices automatically add the second target virtual LAN corresponding to the non-target session port to the non-target session port for redundant backup between traffic. Furthermore, because the direct-connected Layer 2 link interface of the master and standby devices will synchronize the multi-active mechanism detection table entries of all cross-device link aggregation group member ports during the registration process, in this way, when the master and standby systems change, that is, when the roles are switched, part of the traffic will be flooded to the direct-connected Layer 2 link interface, ensuring that the master and standby traffic can be switched at the millisecond level in the fault scenario.

[0076] In this embodiment, after sending the configuration information to the database of each switch, it also includes: judging whether the status detection result indicates that the system process working state meets the preset normal conditions; if the status detection result indicates that the system process working state meets the preset normal conditions, generating prompt information indicating that the cross-device link aggregation group has completed registration; if the status detection result indicates that the system process working state does not meet the preset normal conditions, jumping back to the step of sending the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group. After sending the configuration information to the database of each switch, perform a system self-check, that is, automatically detect whether the registration is completed, for example Figure 2 A specific cross-device link aggregation group registration schematic diagram is shown, which determines whether the status detection result indicates that the system process working status meets the preset normal conditions; if so, the system process working status is marked as active, and a prompt message indicating that the cross-device link aggregation group has completed registration is generated, and the automatic registration process ends; if not, automatic registration is tried again, that is, the process jumps back to the step of sending the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group, so as to ensure that the cross-device link aggregation group completes registration as much as possible.

[0077] In this embodiment, the preset normal condition is that the status detection result characterizes that the session consistency of the cross-device link aggregation group between the main switch and the standby switch is consistent; wherein, the session consistency of the cross-device link aggregation group includes the consistency of the configuration information and the consistency of the media access control address table entries between the main switch and the standby switch. During the system self-check process, the status of the cross-device link aggregation group will be checked to ensure the session consistency of the cross-device link aggregation group between the main and standby systems, wherein the session consistency of the cross-device link aggregation group includes the consistency of the configuration information between the main switch and the standby switch and the synchronization consistency of the media access control address table entries between the main switch and the standby switch. Secondly, the member ports of the cross-device link aggregation group can also be checked to ensure that the configurations such as port isolation are sent to the member ports to ensure the effectiveness of internal functions.

[0078] It can be seen that the present invention sends the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group, so as to restart each switch; if there is no configuration information related to the registration of the cross-device link aggregation group in each switch, the port status of each switch is determined, and if the port status of each switch is in the open state, the message interaction between each switch is controlled; the device information interaction between each switch is controlled based on the received message information, so that each switch uses the device information to configure the target session port of the cross-device link aggregation group and establish the session of the cross-device link aggregation group, thereby completing the registration of the cross-device link aggregation group.

[0079] Beneficial effect: After receiving the preset automatic instructions of the cross-device link aggregation group, the present invention automatically completes the registration of the cross-device link aggregation group, that is, sends the preset automatic instructions to each switch to restart each switch, and controls the message interaction between each switch when the port status of each switch is in the open state, and then controls the interaction of device information between each switch based on the received message information. In this way, each switch uses the device information to configure the target session port of the cross-device link aggregation group and establish a session of the cross-device link aggregation group, thereby automatically completing the registration of the cross-device link aggregation group, thereby improving the efficiency and simplicity of the registration of the cross-device link aggregation group and reducing the requirements for maintenance personnel.

[0080] See also Figure 3 As shown, the embodiment of the present application discloses a specific cross-device link aggregation group registration method, including:

[0081] Step S21: Sending a preset automatic registration instruction of the inter-device link aggregation group to each switch in the inter-device link aggregation group, so as to restart each of the switches.

[0082] The system receives a registration instruction for a cross-device link aggregation group issued by a user. If the instruction is a preset automatic registration instruction, the system automatically executes the cross-device link aggregation group registration process. If the registration instruction is a preset manual registration instruction, the system completes the registration according to the manual configuration instructions issued by the user in sequence.

[0083] Step S22: If the configuration information related to the registration of the cross-device link aggregation group does not exist in each of the switches, the port status of each of the switches is determined; if the port status of each of the switches is in the open state, the messages between the switches are controlled.

[0084] In this embodiment, if there is no configuration information related to the registration of the cross-device link aggregation group in each of the switches, the port status of each of the switches is determined, including: detecting whether there is configuration information related to the registration of the cross-device link aggregation group in each of the switches; if there is configuration information related to the registration of the cross-device link aggregation group in each of the switches, it is determined that the cross-device link aggregation group has currently completed registration; if there is no configuration information related to the registration of the cross-device link aggregation group in each of the switches, it is determined that the cross-device link aggregation group is not currently registered, and the port status of each of the switches is determined. After each switch is restarted, each switch may already have configuration information related to the registration of the cross-device link aggregation group, that is, the registration of the cross-device link aggregation group may have been completed. In this case, there is no need to register the cross-device link aggregation group again. Therefore, in order to avoid redundant registration, it is necessary to detect whether there is configuration information related to the registration of the cross-device link aggregation group in each switch before executing the automatic registration process; if there is configuration information related to the registration of the cross-device link aggregation group in each switch, it is determined that the cross-device link aggregation group has currently completed registration; if there is no configuration information related to the registration of the cross-device link aggregation group in each switch, it is determined that the cross-device link aggregation group is not currently registered, and the port status of each switch is determined. In this way, redundant registration of the cross-device link aggregation group is effectively avoided.

[0085] If the port status of each switch is in the open state, the switches are controlled to perform message interaction, wherein the message is an Ethernet layer (the layer of Ethernet in the network protocol stack) negotiation message, and specifically, the message interaction cycle is, for example, once every 10 seconds.

[0086] Step S23: monitoring whether each of the switches receives corresponding message information within a preset time period.

[0087] It is understandable that during the message interaction process, the message sending time cannot be too long to prevent the switch from being unable to receive the message within a reasonable time period due to an abnormality in the transmission link, thereby blocking the process. Therefore, a preset time period is set, and each switch is monitored to see whether it receives the corresponding message information within the preset time period, so that reasonable processing can be made based on the speed of message interaction later.

[0088] Step S24: If each of the switches receives the corresponding message information within the preset time period, the switches are controlled to interact with each other based on the message information, so that each of the switches uses the device information to configure the target session port of the cross-device link aggregation group and establish a session of the cross-device link aggregation group, thereby completing the registration of the cross-device link aggregation group.

[0089] If each switch receives the corresponding message information within the preset time period, it means that the switch message interaction is normal, then the switch is controlled to interact with each other based on the message information, so that each switch can use the device information to configure the target session port of the cross-device link aggregation group and establish a session of the cross-device link aggregation group, and complete the registration of the cross-device link aggregation group. In this stage, the device will automatically calculate the active and standby roles based on the comparison of the media access control address, use the device address to establish a Transmission Control Protocol (TCP) session link, and use the device address to establish a cross-device link aggregation group session based on the Transmission Control Protocol session.

[0090] Step S25: If each of the switches does not receive the corresponding message information within the preset time period, the process jumps back to the step of sending the preset automatic registration instruction of the inter-device link aggregation group to each switch in the inter-device link aggregation group.

[0091] In this embodiment, if each of the switches does not receive the corresponding message information within the preset time period, then the step of re-jumping to the step of sending the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group includes: if each of the switches does not receive the corresponding message information within the preset time period, then determining whether the current number of registration attempts for the cross-device link aggregation group is less than the preset number of attempts threshold; if the current number of registration attempts for the cross-device link aggregation group is less than the preset number of attempts threshold, then generating a message interaction abnormality prompt message to re-jump to the step of sending the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group, and updating the current number of registration attempts for the cross-device link aggregation group.

[0092] If each switch fails to receive the corresponding message information within the preset time period, the registration process can be attempted again. However, before attempting to execute the registration process, it is necessary to determine whether the number of registration attempts of the current cross-device link aggregation group is less than the preset attempt number threshold. That is, if each switch fails to receive the corresponding message information within the preset time period and the number of registration attempts of the current cross-device link aggregation group is less than the preset attempt number threshold, then the registration process can be attempted again, that is, message interaction abnormality prompt information is generated to jump again to the step of sending the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group. Because the system may not be able to automatically complete the registration of the cross-device link aggregation group at one time due to network failures and other reasons, automatic re-registration can be attempted. However, if the registration is not successful within a certain number of attempts, it is no longer suitable to retry at this time. That is, even if the registration is attempted again, the probability of successful registration is very low, so the system stops automatic registration. When the user handles the situation and issues a preset automatic registration instruction, the system will retry automatic registration. In this way, the system will not be blocked in the registration attempt process.

[0093] It can be seen that the present invention automatically completes the registration of the cross-device link aggregation group, specifically including sending preset automatic instructions to each switch to restart each switch, and controlling the message interaction between each switch when the port status of each switch is in the open state, and then controlling the device information interaction between each switch based on the received message information. In this way, each switch uses the device information to configure the target session port of the cross-device link aggregation group and establish a session of the cross-device link aggregation group, thereby automatically completing the registration of the cross-device link aggregation group, thereby improving the efficiency and simplicity of the registration of the cross-device link aggregation group and reducing the requirements for maintenance personnel; wherein, in controlling the received messages between each switch, During the process of exchanging device information, monitor whether each switch receives the corresponding message information within the preset time period. If each switch receives the corresponding message information within the preset time period, control the exchange of device information between each switch based on the message information. If each switch does not receive the corresponding message information within the preset time period and the current registration attempt number of the cross-device link aggregation group is less than the preset attempt number threshold, try to start a new round of automatic registration process. If each switch does not receive the corresponding message information within the preset time period and the current registration attempt number of the cross-device link aggregation group is not less than the preset attempt number threshold, stop starting a new round of automatic registration process, and effectively avoid the system being blocked in the registration attempt process.

[0094] See also Figure 4 As shown, the embodiment of the present application discloses a cross-device link aggregation group registration device, including:

[0095] The switch restart module 11 is used to send a preset automatic registration instruction of the inter-device link aggregation group to each switch in the inter-device link aggregation group, so as to restart each of the switches.

[0096] The message interaction module 12 is used to determine the port status of each switch if there is no configuration information related to the cross-device link aggregation group registration in each switch, and control the message interaction between each switch if the port status of each switch is open.

[0097] The registration completion module 13 is used to control the interaction of device information between each of the switches based on the received message information, so that each of the switches uses the device information to configure the target session port of the cross-device link aggregation group and establish the session of the cross-device link aggregation group, thereby completing the registration of the cross-device link aggregation group.

[0098] It can be seen that the present invention sends the preset automatic registration instruction of the cross-device link aggregation group to each switch in the cross-device link aggregation group, so as to restart each switch; if there is no configuration information related to the registration of the cross-device link aggregation group in each switch, the port status of each switch is determined, and if the port status of each switch is in the open state, the message interaction between each switch is controlled; the device information interaction between each switch is controlled based on the received message information, so that each switch uses the device information to configure the target session port of the cross-device link aggregation group and establish the session of the cross-device link aggregation group, thereby completing the registration of the cross-device link aggregation group.

[0099] Beneficial effect: After receiving the preset automatic instructions of the cross-device link aggregation group, the present invention automatically completes the registration of the cross-device link aggregation group, that is, sends the preset automatic instructions to each switch to restart each switch, and controls the message interaction between each switch when the port status of each switch is in the open state, and then controls the interaction of device information between each switch based on the received message information. In this way, each switch uses the device information to configure the target session port of the cross-device link aggregation group and establish a session of the cross-device link aggregation group, thereby automatically completing the registration of the cross-device link aggregation group, thereby improving the efficiency and simplicity of the registration of the cross-device link aggregation group and reducing the requirements for maintenance personnel.
