[0028] Figure 1 A flow chart of a link automatic aggregation method provided by an embodiment of the present application. The embodiment of the present application can be applicable to the case of automatically performing aggregation on link ports between different devices. The method can be performed by a link automatic aggregation device, which can be realized in the form of hardware and / or software, and can be configured in an electronic device for implementing the link automatic aggregation method. As shown in the figure, the method comprises: Figure 1

[0029] ​S101, link aggregation information of a first device port is acquired based on an LLDP protocol, the first device port is an actual physical interface used for connecting devices for communication transmission, the link aggregation information includes: port aggregation performance, port aggregation status, and device classification of a device to which the port belongs, the port aggregation performance is whether the device port supports being configured to perform port aggregation, the port aggregation status is used to indicate whether the device port has been configured in the belonging aggregation group, the device classification is a master device or a slave device, the aggregation group is a logical port established by multiple device ports belonging to the same device, and the port aggregation is to control the device port to be configured in the belonging aggregation group.

[0030] In the embodiment of the application, the link layer discovery protocol (LLDP) can refer to a network protocol used for mutual identification between devices and automatic discovery of a network topology. Referring to Figure 2 , the actual physical interface can refer to an actual physical port on a device in an Ethernet network, which is used for connection or communication transmission between different devices, for example Figure 2 port A1, A2, A3, B1, B2, and B3. The aggregation group can refer to a logical port established for multiple physical ports on the same device, for example Figure 2 aggregation group A includes ports A1, A2, and A3, and aggregation group B includes ports B1, B2, and B3. The port aggregation can refer to bundling multiple physical ports into an aggregation group. The port aggregation performance can refer to whether the device port has the performance to support performing port aggregation. The port aggregation status can refer to a state used to indicate whether the device port has performed port aggregation and has been configured in the belonging aggregation group.

[0031] Specifically, the port aggregation performance, the port aggregation state and the device classification of the device to which the port belongs of the first device port can be obtained through the LLDP protocol, thereby forming the link aggregation information of the first device port. For example, the LLDP protocol supports the TLV data encoding format, and thus the link aggregation information of the device port can be expressed in the TLV format. For example, three bits in the TLV format can be used to express the link aggregation information, i.e., bit 0: aggCap, representing the port aggregation performance, when the device port supports being configured to perform port aggregation, aggCap = 1, otherwise aggCap = 0; bit 1: aggStat, representing the port aggregation state, when the device port has been configured in the aggregation group to which it belongs, aggStat = 1, otherwise aggStat = 0; bit 2: aggAct, representing the device classification of the device to which the port belongs, when the device classification of the device to which the device port belongs is the master device, aggAct = 1, when the device classification of the device to which the device port belongs is the slave device, aggAct = 0. Further, the link aggregation information of the device port can be expressed as (aggCap, aggStat, aggAct).

[0032] As an optional implementation of the embodiment of the application, the link aggregation information of the first device port is obtained based on the LLDP protocol, including: if the first device port supports being configured in the aggregation group, the port aggregation performance in the link aggregation information of the first device port indicates that the device port supports being configured to perform port aggregation; and if the first device port can be controlled to communicate through the aggregation group to which it belongs, the port aggregation state in the link aggregation information of the first device port indicates that the device port has been configured in the aggregation group.

[0033] Specifically, if the first device port is set to support being configured in the aggregation group, the port aggregation performance of the first device port indicates that the first device port supports performing port aggregation, otherwise the port aggregation performance of the first device port indicates that the first device port does not support performing port aggregation. If the aggregation group to which the first device port belongs can control the first device port to connect between devices or transmit communication, the port aggregation state of the first device port indicates that the first device port is complete port aggregation and has been configured in the aggregation group to which it belongs, otherwise the port aggregation state of the first device port indicates that the first device port is not configured in the aggregation group to which it belongs.

[0034] S102, if the link aggregation information of the first device port indicates that the device classification of the device to which the first device port belongs is the master device, it is judged whether the link aggregation information of the first device port conforms to the preset aggregation information, the preset aggregation information indicating that the port aggregation performance in the link aggregation information indicates that the device port supports being configured to perform port aggregation and the port aggregation state indicates that the device port is not configured in the aggregation group.

[0035] In the embodiments of the present application, the preset aggregation information can refer to information preset for judging whether the device port can perform port aggregation. The preset aggregation information can be that the port aggregation performance indicates that the device port has the performance of performing port aggregation, and the port aggregation state indicates that the device port is in a state of not performing port aggregation configured in the aggregation group.

[0036] Specifically, according to the device classification of the device to which the first device port belongs in the link aggregation information of the first device port, it can be judged whether the device classification of the device to which the first device port belongs is the master device. Further, if the device classification of the device to which the first device port belongs is the master device, it can be judged whether the link aggregation information of the first device port conforms to the preset aggregation information according to the port aggregation performance and the port aggregation state in the link aggregation information of the first device port. If the device classification of the device to which the first device port belongs is the slave device, the link aggregation is not performed.

[0037] S103, if the link aggregation information of the first device port conforms to the preset aggregation information, the link aggregation information of the second device port is obtained based on the LLDP protocol, the second device port is connected with the first device port and belongs to different devices, the second device port and the first device port belong to different devices, and the aggregation group to which the second device port belongs can communicate with the aggregation group to which the first device port belongs.

[0038] In the embodiments of the present application, the second device port can refer to an actual physical interface on a different device from the first device port, and the second device port and the first device port can form a link when connected, and the aggregation group to which the second device port belongs can communicate with the aggregation group to which the first device port belongs. For example, referring to Figure 2 , the ports A1 and B1 are connected, the ports A2 and B2 are connected, the ports A3 and B3 are connected, and the aggregation group A and the aggregation group B can communicate.

[0039] Specifically, according to the link aggregation information of the first device port, it can be judged whether the link aggregation information of the first device port conforms to the preset aggregation information. Further, if the link aggregation information of the first device port conforms to the preset aggregation information, the port aggregation performance, the port aggregation state and the device classification of the device to which the second device port belongs can be obtained based on the LLDP protocol to form the link aggregation information of the second device port. The acquisition method of the link aggregation information of the second device port is similar to the acquisition method of the link aggregation information of the first device port. If the link aggregation information of the first device port does not conform to the preset aggregation information, the link aggregation is not performed.

[0040] For example, when the link aggregation information of the first device port is represented by the TLV format of the LLDP protocol as (1, 0, 1), it can be considered that the link aggregation information of the first device port conforms to the preset aggregation information.

[0041] As an alternative, the link aggregation information of the second device port is acquired based on the LLDP protocol, including: if the second device port supports being configured in an aggregation group, the port aggregation performance in the link aggregation information of the second device port indicates that the second device port supports being configured to perform port aggregation; and if the second device port can be controlled to communicate through the aggregation group to which the second device port belongs, the port aggregation state in the link aggregation information of the second device port indicates that the second device port has been configured in the aggregation group.

[0042] As an alternative embodiment of the embodiment of the application, after the link aggregation information of the second device port is acquired based on the LLDP protocol, it further includes: if the device classification of the device to which the port belongs in the link aggregation information of the second device port is a master device, determining the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port according to the physical addresses of the devices to which the first device port and the second device port belong respectively.

[0043] Specifically, according to the device classification of the device to which the port belongs in the link aggregation information of the second device port, it can be determined whether the device classification of the device to which the second device port belongs is a master device. Further, if the device classification of the device to which the second device port belongs is a master device, the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port is determined according to the physical addresses of the devices to which the first device port and the second device port belong respectively. If the device classification of the device to which the second device port belongs is a slave device, the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port is not modified.

[0044] For example, if the physical address of the device to which the second device port belongs is less than the physical address of the device to which the first device port belongs, the device classification of the device to which the port belongs in the link aggregation information of the second device port is a master device, and the device classification of the device to which the port belongs in the link aggregation information of the first device port is a slave device. If the physical address of the device to which the second device port belongs is not less than the physical address of the device to which the first device port belongs, the device classification of the device to which the port belongs in the link aggregation information of the second device port is a slave device, and the device classification of the device to which the port belongs in the link aggregation information of the first device port is a master device.

[0045] S104, if the link aggregation information of the second device port conforms to the preset aggregation information, controlling the first device port and the second device port to perform link aggregation, and the link aggregation is realized by controlling the first device port to perform port aggregation and controlling the second device port to perform port aggregation.

[0046] Specifically, according to the link aggregation information of the second device port, it can be judged whether the link aggregation information of the second device port conforms to the preset aggregation information. Further, if the link aggregation information of the second device port conforms to the preset aggregation information, the first device port is controlled to perform port aggregation and the second device port is controlled to perform port aggregation, so as to realize link aggregation of the first device port and the second device port. If the link aggregation information of the second device port does not conform to the preset aggregation information, link aggregation is not performed.

[0047] As an optional implementation of the embodiment of the present application, the control of the first device port and the second device port to perform link aggregation comprises: if, in the process of performing link aggregation of the first device port and the second device port, the link aggregation information of the first device port or the second device port indicates that the port aggregation performance of the first device port or the second device port does not support the configured port aggregation, the first device port and the second device port are controlled to exit the link aggregation.

[0048] Specifically, in the process of performing link aggregation of the first device port and the second device port, if the first device port or the second device port does not support port aggregation, it indicates that the link aggregation information of the first device port or the second device port does not conform to the preset aggregation information. Further, the first device port and the second device port are respectively controlled to exit the port aggregation, so as to realize the exit of the link aggregation.

[0049] As an optional implementation of the embodiment of the present application, the control of the first device port and the second device port to exit the link aggregation comprises: if the link aggregation information of the second device port indicates that the second device port does not support the configured port aggregation, the first device port and the second device port are controlled to exit the link aggregation and wait for the link aggregation information of the second device port to conform to the preset aggregation information before performing the link aggregation again.

[0050] Specifically, in the process of performing link aggregation of the first device port and the second device port, if the second device port does not support port aggregation, the link aggregation information of the second device port does not conform to the preset aggregation information. Further, the first device port and the second device port are controlled to exit the link aggregation, and after the link aggregation information of the second device port conforms to the preset aggregation information, the first device port and the second device port are controlled to perform the link aggregation again, so as to avoid judging again whether the link aggregation information of the first device port conforms to the preset aggregation information.

[0051] As an optional implementation of this invention, controlling the first device port and the second device port to perform link aggregation includes: determining the order in which the first device port and the second device port perform port aggregation based on the device classification of the device to which the port belongs in the link aggregation information of the first device port and the second device port.

[0052] Specifically, when controlling the first and second device ports to perform link aggregation, the order in which the first and second device ports perform port aggregation can be determined by the device classification of the devices to which they belong. For example, a device port classified as a master device performs port aggregation before a device port classified as a slave device. Correspondingly, when controlling the first and second device ports to exit link aggregation, if a device port classified as a slave device does not support port aggregation, then the device port classified as a master device exits port aggregation and waits for the link aggregation information of the device port classified as a slave device to match preset aggregation information before re-executing port aggregation.

[0053] As an optional implementation of the present invention, the automatic link aggregation method of the present invention further includes: after the link aggregation is performed on the first device port and the second device port, updating the link aggregation information of the first device port and the second device port.

[0054] Specifically, after the first device port and the second device port complete link aggregation, the port aggregation status in the link aggregation information of both the first and second device ports is updated to indicate that the device port has been configured in its respective aggregation group. For example, after the first device port and the second device port complete link aggregation, when the link aggregation information is represented in TLV format, aggStat is updated to 1.

[0055] The technical scheme of the embodiment of the present application acquires the link aggregation information of the first device port based on the LLDP protocol, the first device port is an actual physical interface used for connecting devices for communication transmission, the link aggregation information includes: port aggregation performance, port aggregation state and device classification of the device to which the port belongs, the port aggregation performance is whether the device port supports being configured to perform port aggregation, the port aggregation state is used to indicate whether the device port has been configured in the aggregation group to which it belongs, the device classification is a master device or a slave device, the aggregation group is a logical port established by multiple device ports belonging to the same device, and the port aggregation is to control the device port to be configured in the aggregation group to which it belongs, thereby realizing the acquisition of the link aggregation information of the first device port through the LLDP protocol, reducing the device operation and maintenance cost, and avoiding the occupation of system resources; if the link aggregation information of the first device port indicates that the device classification of the device to which the first device port belongs is a master device, it is judged whether the link aggregation information of the first device port meets the preset aggregation information, the preset aggregation information indicates that the port aggregation performance in the link aggregation information indicates that the device port supports being configured to perform port aggregation, and the port aggregation state indicates that the device port is not configured in the aggregation group, thereby realizing the judgment of whether the first device port supports performing port aggregation through the link aggregation information of the first device port, and improving the efficiency of link aggregation; if the link aggregation information of the first device port meets the preset aggregation information, the link aggregation information of the second device port is acquired based on the LLDP protocol, the second device port is connected with the first device port, and the second device port and the first device port belong to different devices, the aggregation group to which the second device port belongs and the aggregation group to which the first device port belongs can communicate, thereby realizing the acquisition of the link aggregation information of the second device port through the LLDP protocol; if the link aggregation information of the second device port meets the preset aggregation information, the first device port and the second device port are controlled to perform link aggregation, the link aggregation is realized by controlling the first device port to perform port aggregation and controlling the second device port to perform port aggregation, thereby realizing the control of the first device port and the second device port to perform port aggregation, so as to control the execution of link aggregation, improve the accuracy of link aggregation, and avoid the aggregation configuration error to cause the business to be not connected and the network to be paralyzed.
