[0002] With the advent of the AI ​​and digital age, the demand for intelligent communications is growing. When building a complex network topology, the core of the current strategy is logical destruction, blocking one of the switch ports to prevent loops in the network topology. However, this solution wastes bandwidth and makes the backup link unusable.

[0003] In the related art, link aggregation can also be configured to prevent loops from occurring in the network topology. Link aggregation refers to aggregating multiple physical ports of a switch to form a logical port to achieve load sharing of traffic on each physical port.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] It should be noted that the terms "including" and "having" and their variations involved in the documents of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided by the embodiment of the present application. The method may be executed or executed in parallel in the actual processing process or when the device is executed in accordance with the method sequence shown in the embodiment or drawings.

[0023] Figure 1 A flowchart of a link aggregation method provided by an embodiment of the present application is shown. Figure 1 As shown, the link aggregation method may include the following steps: Step S101: receiving a first LLDP message sent by a second switch.

[0024] The first LLDP message carries the link aggregation information of the second switch.

[0025] The first switch and the second switch in the embodiment of the present application both support the LLDP protocol, so the first switch and the second switch can exchange link aggregation information with each other by sending LLDP messages to each other and receiving LLDP messages sent by each other.

[0026] Exemplarily, in order to distinguish between the LLDP messages, in the embodiment of the present application, the received LLDP message sent by the second switch is described as the first LLDP message.

[0027] Step S102: Determine whether there is a direct connection loop between the second switch and the first switch according to the link aggregation information of the second switch, and determine whether the second switch and the first switch meet the link aggregation condition.

[0028] The link aggregation information of the second switch includes device identification information and port identification information of the second switch.

[0029] In a specific implementation, the first switch may determine whether the received multiple first LLDP messages come from different ports of the second switch according to the device identification information and port identification information of the second switch carried in each of the received multiple first LLDP messages.

[0030] Further, if it is determined that the received multiple first LLDP messages come from different ports of the second switch, it is determined that a direct loop exists between the second switch and the first switch; otherwise, it is determined that no direct loop exists between the second switch and the first switch.

[0031] Figure 2 A network topology diagram provided in an embodiment of the present application is shown, such as Figure 2 As shown, the first port 11 and the first port 12 of the first switch are connected to the second port 21 and the second port 22 of the second switch respectively through two Ethernet cables. That is to say, the link aggregation information carried by the first LLDP message received by the first port 11 of the first switch includes the device identification information of the second switch and the identification information of the second port 21. And the link aggregation information carried by the first LLDP message received by the first port 12 of the first switch includes the device identification information of the second switch and the identification information of the second port 22. At this time, the first switch can determine that the two received first LLDP messages are from two different ports of the second switch. Therefore, it can be determined that there is a direct loop between the second switch and the first switch.

[0032] In a specific implementation, the configuration format of the link aggregation information can be in TLV format. The LLDP protocol stipulates that each LLDPDU (link layer discovery protocol data unit) can carry a total of 32 TLVs, and each LLDPDU starts with Chassis ID TLV, Port ID TLV and Time to Live TLV, and ends with End of LLDPDU TLV. These four TLVs are mandatory TLVs, and the others are optional TLVs.

[0033] Among them, LLDPDU is the data part of the LLDP message, which is used to carry the link aggregation information in the embodiment of the present application.

[0034] Continue with Figure 2For example, the device identification information of the second switch carried by the two first LLDP messages is the same, which can be Chassis ID TLV: MAC address of the second switch. However, the port identification information of the second switch carried by the two first LLDP messages is different, which are Port ID TLV: Port GigabitEthernet21 of the second switch and Port ID TLV: Port GigabitEthernet22 of the second switch.

[0035] Thus, the first switch can determine that the received multiple first LLDP messages are from different ports of the second switch based on the device identification information and port identification information of the second switch carried in each of the received multiple first LLDP messages, thereby determining that a direct connection loop exists between the second switch and the first switch.

[0036] However, it should be noted that Figure 2 The example in which the first switch and the second switch are connected via two Ethernet cables is used for illustration. In a specific implementation, the switches may be connected via more Ethernet cables. For example, the first switch and the second switch may be connected via three Ethernet cables. This application does not limit this.

[0037] Furthermore, the first switch may also determine whether the second switch and the first switch meet the link aggregation condition according to the link aggregation information of the second switch.

[0038] In a specific implementation, it can be determined whether the link aggregation information of the second switch includes a target field for automatic loop aggregation. If the target field for automatic loop aggregation is included, it can be determined that the second switch and the first switch meet the link aggregation condition. Otherwise, it is determined that the second switch and the first switch do not meet the link aggregation condition.

[0039] Continue with Figure 2 For example, the target field of the loop automatic aggregation of the second switch carried by the two first LLDP messages can be configured in the Specific TLV: LoopAutoAgg.

[0040] Among them, Specific TLV is an extended field of TLV, and the target field of loop automatic aggregation LoopAutoAgg is used to indicate that the second switch supports automatic link aggregation. In other words, the first switch needs to determine whether the second switch also supports automatic link aggregation. If the second switch supports automatic link aggregation, the first switch can complete the subsequent automatic link aggregation operation, so that the ports corresponding to the direct-connected loop can be automatically aggregated to prevent loops.

[0041] It should be noted that, in step S102, the order of determining whether there is a direct loop between the second switch and the first switch, and determining whether the second switch and the first switch meet the link aggregation condition can be set according to actual needs.

[0042] In some embodiments, it is possible to first determine whether there is a direct loop between the second switch and the first switch, and if so, then determine whether the second switch and the first switch meet the conditions for link aggregation. In other embodiments, it is also possible to first determine whether the second switch and the first switch meet the conditions for link aggregation, and if the conditions for link aggregation are met, then determine whether there is a direct loop between the second switch and the first switch. In other embodiments, it is also possible to simultaneously determine whether there is a direct loop between the second switch and the first switch, and whether the second switch and the first switch meet the conditions for link aggregation, and this application does not impose any limitation on this.

[0043] Step S103: If a direct loop exists between the second switch and the first switch, and the second switch and the first switch meet the link aggregation condition, each first port corresponding to the direct loop is determined as a first port to be aggregated.

[0044] In a specific implementation, if it is determined that there is a direct connection loop between the second switch and the first switch, and the second switch and the first switch meet the link aggregation condition, then the first ports corresponding to the direct connection loop can be determined in the following manner: If the multiple first LLDP messages received come from different ports of the second switch, the multiple first ports that receive the multiple first LLDP messages may be used as the first ports corresponding to the direct-connected loops.

[0045] Continue with Figure 2 For example, the port identification information of the second switch carried by the two first LLDP messages is Port ID TLV: Port GigabitEthernet21 of the second switch, and Port ID TLV: Port GigabitEthernet22 of the second switch. Then, it can be determined that the port receiving the first LLDP message sent by the GigabitEthernet21 port is GigabitEthernet11, that is, the first port 11. Similarly, it can be determined that the port receiving the first LLDP message sent by the GigabitEthernet22 port is GigabitEthernet12, that is, the first port 12. Further, it can be determined that the first port 11 and the first port 12 are the first ports corresponding to the directly connected loop, and the first port 11 and the first port 12 are used as the first ports to be aggregated.

[0046] Step S104: configure the first port to be aggregated as a first aggregation port.

[0047] The first switch determines that there is a direct loop between the second switch and the first switch, and the second switch and the first switch meet the link aggregation condition. Then, after each first port corresponding to the direct loop is used as a first port to be aggregated, the first port to be aggregated can be configured as a first aggregation port.

[0048] Continue with Figure 2 For example, after the first switch determines that the first port 11 and the first port 12 are the first ports to be aggregated, it can automatically create a static aggregation group Aggr1 and add the first port 11 and the first port 12 to the static aggregation group Aggr1, thereby automatically configuring the first port to be aggregated as the first aggregation port.

[0049] In an optional implementation, before the first switch determines whether there is a direct loop between the second switch and the first switch based on the link aggregation information of the second switch, and determines whether the second switch and the first switch meet the link aggregation conditions, the first switch may also send a second LLDP message to the second switch, so that the second switch determines that each second port corresponding to the direct loop is a second port to be aggregated, and configures the second port to be aggregated as a second aggregation port.

[0050] The second LLDP message carries the link aggregation information of the first switch, and the link aggregation information includes the device identification information, port identification information and the target field of the automatic loop aggregation of the first switch. The target field of the automatic loop aggregation is used to indicate that the first switch supports automatic link aggregation.

[0051] A link aggregation method provided in an embodiment of the present application can determine the existence of a direct loop between switches through LLDP messages, and when the link aggregation conditions are met, determine the first ports corresponding to the direct loop as the first ports to be aggregated, and configure the first ports to be aggregated as the first aggregation ports, without the need for manual configuration by the administrator, thereby achieving automatic link aggregation between switches, thereby achieving the dual advantages of automatic loop breaking and increasing link bandwidth. At the same time, the switch device in the embodiment of the present application does not need to support the LACP protocol, so that the hardware cost when building the network topology can be saved.

[0052] Figure 3 An interactive flow chart of a link aggregation method provided by an embodiment of the present application is shown, such as Figure 3 As shown, the link aggregation method may include the following steps: Step S301: The first switch sends a second LLDP message to the second switch.

[0053] The second LLDP message carries the link aggregation information of the first switch.

[0054] Step S302: The second switch sends a first LLDP message to the first switch.

[0055] The first LLDP message carries the link aggregation information of the second switch.

[0056] Step S303: The first switch receives a first LLDP message sent by the second switch.

[0057] Step S304: The second switch receives the second LLDP message sent by the first switch.

[0058] Step S305: The first switch determines, based on the link aggregation information of the second switch, that there is a direct loop between the second switch and the first switch, and determines that the second switch and the first switch meet a link aggregation condition.

[0059] The link aggregation information of the second switch includes device identification information of the second switch, port identification information, and a target field for automatic loop aggregation.

[0060] Step S306: The second switch determines, based on the link aggregation information of the first switch, that there is a direct loop between the first switch and the second switch, and determines that the first switch and the second switch meet a link aggregation condition.

[0061] The link aggregation information of the first switch includes the device identification information, port identification information and the target field of the automatic loop aggregation of the first switch. The process of the second switch determining that there is a direct loop between the first switch and the second switch and determining that the first switch and the second switch meet the link aggregation conditions according to the link aggregation information of the first switch is the same as the process of the first switch determining that there is a direct loop between the second switch and the first switch and determining that the second switch and the first switch meet the link aggregation conditions according to the link aggregation information of the second switch, and will not be repeated here.

[0062] Step S307: The first switch determines each first port corresponding to the directly connected loop as a first port to be aggregated.

[0063] Step S308: The second switch determines each second port corresponding to the directly connected loop as a second port to be aggregated.

[0064] The process of the second switch determining each second port corresponding to the direct-connected loop as the second port to be aggregated is the same as the process of the first switch determining each first port corresponding to the direct-connected loop as the first port to be aggregated, which is not repeated here.

[0065] Step S309: The first switch configures the first port to be aggregated as a first aggregation port.

[0066] Step S310: The second switch configures the second port to be aggregated as a second aggregation port.

[0067] The process of configuring the second port to be aggregated as the second aggregate port by the second switch is the same as the process of configuring the first port to be aggregated as the first aggregate port by the first switch, which will not be described in detail here.
