Description

Technical Field

[0001] The present application relates to the field of network communication technology, and in particular to a local area network switch configuration method and device. Background Art

[0002] In a three-layer network, a LAN switch (LSW) is required to ensure connectivity between devices and the controller. That is, all three layer devices in the network (spine, leaf, and access) need to connect to the controller through the LSW.

[0003] In current controller automation and new automation solutions, users must first connect the network cables and manually configure the LSW before managing devices. This ensures that downstream devices can communicate with the controller before initiating the automated management process. However, manual configuration requires maintenance personnel to enter specific configuration commands on the devices, distributing different configurations to different ports. This lacks automated distribution, making it prone to errors and difficult to troubleshoot, making it less user-friendly. Summary of the Invention

[0051] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms "a," "the," and "the" used in this application and claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to any or all possible combinations of one or more associated listed items.

[0052] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" used may also be interpreted as "at the time of" or "when" or "in response to determining".

[0053] For example, see Figure 1The figure shows a schematic diagram of a three-layer networking model provided by an embodiment of the present application. In the networking, an LSW (LAN Switch) is required to ensure the connection between the device and the controller. That is, the three-layer devices in the network in the figure: Spine, Leaf, and Access all need to connect to the controller through the LSW. The lower-layer directly connected device of the LSW is the Spine device, the lower-layer directly connected device of the Spine device is the Leaf device, and the lower-layer directly connected device of the Leaf device is the Access device. APs and wired users access the network through the Access device.

[0054] Currently, managing network devices on a controller requires not only pre-planning the network but also manual configuration of the LSWs used to connect the controller to each layer of network devices. Manual configuration is more complex and error-prone than automated configuration, making it less user-friendly. This inefficiency and complexity of the management process are driving challenges. Improving network management and configuration efficiency and streamlining the configuration process are pressing challenges.

[0055] For example, see Figure 2 FIG. 1 is a detailed flow chart of a method for configuring a local area network switch provided in an embodiment of the present application. The method is applied to a controller, wherein a whitelist of devices to be managed is preset on the controller. The whitelist includes the device serial numbers and device roles of the devices to be managed. The method comprises the following steps:

[0056] Step 200: After detecting that a websocket connection is established with a target network device, obtain a target device serial number of the target network device.

[0057] The target network device initiates a request to establish a websocket connection with the controller after determining that it has created a first VLAN virtual interface and the IP address of the first VLAN is configured as the IP address of the first network segment.

[0058] First, manually configure the physical connections of each device in the network, including the interface (physical connection) of the LSW connection service. Then, the user creates a first VLAN virtual interface (e.g., VLAN 1 virtual interface) on the LSW and assigns an IP address to the first VLAN virtual interface from the preset IP network segment (IP pool) corresponding to VLAN 1.

[0059] In practical applications, the IP address configured on a VLAN virtual interface can be understood as the gateway address of the IP address of that network segment. In the embodiment of the present application, the network of the first VLAN virtual interface (VLAN 1) is used for automatic online access of the LAN switch. Specifically, the LAN switch establishes a WebSocket connection (a three-way handshake) with the controller. During the WebSocket establishment process, the controller can obtain the device serial number of the LAN switch and, further, the VLAN 1 IP address of the LAN switch.

[0060] Step 210: Based on the target device serial number and the whitelist, determine whether the target network device is a local area network switch.

[0061] In the embodiment of the present application, a whitelist is pre-configured on the controller, that is, a list of items corresponding to each device and LSW in the network. For example:

[0062] Device 1: Device serial number (A): Role (LSW);

[0063] Device 2: Device serial number (B): Role (Spine 1);

[0064] Device 3: Device serial number (C): Role (Spine 2);

[0065] Device 4: Device serial number (D): Role (Leaf 1);

[0066] …….

[0067] Then, after receiving the websocket connection established between the target network device and itself, the controller determines the device role of the target network device based on the device serial number of the target network device, and executes corresponding configuration steps according to the determined device role.

[0068] Step 220: If yes, configure a second VLAN virtual interface of the target network device, configure the IP address of the second VLAN virtual interface as the IP address of the second network segment, and configure a static route from the target network device to the controller.

[0069] For example, the controller sends a configuration to the LSW, configuring a second VLAN (e.g., VLAN 4094), a second VLAN virtual interface (e.g., VLAN 4094 virtual interface), and a 4094 gateway address (allocating an IP address in the second network segment to the VLAN 4094 virtual interface). At the same time, a static route is configured for the LSW, which is a static route to the controller.

[0070] In the embodiment of the present application, after determining that the target network device is a LAN switch, the method can further include the following steps:

[0071] The first network segment IP address of the target network device is obtained, the fabric to which the target network device belongs is determined, and when it is determined that the fabric to which the target network device belongs is not configured with a LAN switch, the steps of configuring a second VLAN virtual interface of the target network device, configuring the IP address of the second VLAN virtual interface as the IP address of the second network segment, and configuring the static route of the target network device to the controller are performed, otherwise, the process is ended.

[0072] That is, if the network includes different fabrics, different first network segments can be preset for different fabrics. For example, for fabric1 included in the network, the first VLAN virtual interface (VLAN 1) of each device in fabric1 corresponds to network segment 1, and the first VLAN virtual interface (VLAN 1) of each device in fabric1 corresponds to network segment 2. Then, after determining that the target network device is a LAN switch, the fabric to which the LAN switch belongs can be further determined according to the first VLAN IP address of the target network device. If the fabric is configured with a LAN switch, the target network device is not configured, otherwise, the target network device is configured.

[0073] Step 230: The target network device is managed, the downlink interface information of the target network device used to connect the lower layer device is obtained, and the downlink interface is configured to pass through all VLANs.

[0074] In practical applications, after the controller is managed to the LAN switch, the device port information of the LAN switch can be obtained, such as which downlink interfaces (interfaces used to connect the lower layer Spine device) the LAN switch has, or which interfaces are idle (not configured). Then, an instruction for instructing the interface to pass through all VLANs (VLAN 1-VLAN 4094) is issued to the LAN switch.

[0075] In the embodiment of the present application, the DHCP function is enabled on the target network device, and the DHCP Relay function is enabled on the first VLAN virtual interface; the Access device accesses the Leaf device in the network, the Leaf device accesses the Spine device, the Spine device accesses the LAN switch, and the LAN switch is directly connected to the controller; the method further includes the following steps:

[0076] After determining that the configuration of the upper-layer device is complete, obtaining link information between the upper-layer device and each lower-layer device connected to the upper-layer device, and based on the link information, configuring an IP address of the first network segment for each lower-layer device, so that each lower-layer device establishes a websocket connection with the controller;

[0077] After detecting that a websocket connection has been established with each lower-level device, configurations are sent to each lower-level device.

[0078] In the embodiment of the present application, when sending configurations to each lower-layer device, a preferred implementation method is:

[0079] Configure the second VLAN virtual interface of each next-layer device, configure the IP address of the second VLAN virtual interface as the IP address of the second network segment, and configure the static route from each next-layer device to the controller; determine the device role of the next-layer device based on the device serial number and whitelist list of each next-layer device; determine the networking configuration corresponding to the device role based on the device role of the next-layer device, and send the networking configuration to the next-layer device.

[0080] For example, the link information between the target network device and each Spine device connected to the target network device is obtained, and based on the link information, the IP address of the first network segment is configured for each Spine device respectively, so that each Spine device establishes a websocket connection with the controller; after detecting that a websocket connection is established with each Spine device, the configuration is sent to each Spine device.

[0081] In an embodiment of the present application, after the target network device is managed, the downlink interface information of the target network device used to connect to the lower-layer device is obtained, and the downlink interface is configured to pass all VLANs, if a user-triggered configuration retraction instruction is received, it is determined that there is no downlink interface of the lower-layer device connected to the target network device, and the configuration issued to the downlink interface is retracted.

[0082] For example, after managing and configuring a LAN switch, when automatically configuring other spine, leaf, and access nodes, you may be prompted to "reclaim other interface configurations on the LSW." Specifically, you can choose whether to reclaim other interface configurations on the configuration page. If you select "Yes," all interfaces on the device that have been configured are obtained, and then the interconnection links between the LSW and the spine are determined based on the topology (other interfaces that are not interconnected with the spine can be determined). Finally, the configurations of the remaining interfaces are reclaimed.

[0083] Furthermore, in an embodiment of the present application, based on the topology information, it is determined whether there are multiple interconnected ports between the target network device and each Spine device. If so, the target network device and the corresponding Spine device are instructed to create an aggregation group based on the multiple interconnected ports, and the relevant information of the created aggregation group is maintained locally.

[0084] For example, the controller determines whether the LSW has multiple interconnected ports with each spine device. If so, it instructs the LSW and the corresponding spine device to create an aggregation group. The controller maintains the aggregation group information locally.

[0085] In actual applications, in addition to the existing devices, the nodes displayed on the topology page include newly added LSW nodes. LSW is distinguished from other devices, and the node shape, status color, etc. can be designed separately. LSW devices are not displayed in the network element list, but only on the topology page. LSW devices can right-click on the topology page to select the new function, which allows the deletion of LSW. Right-click to add the function of configuring a downlink port (such as connecting an idle downlink port to a new spine device). Since the configuration of all idle interfaces may be restored after the above automation, if an interface needs to be newly connected to a device, the configuration can be issued separately to a certain interface of the device here.

[0086] For example, see Figure 3 FIG. 1 is a schematic diagram of a configuration device for a local area network switch according to an embodiment of the present invention. The device is applied to a controller, and a whitelist of devices to be managed is preset on the controller.
