Description

Technical Field

[0001] The present application relates to the field of network management technology, and in particular to a method and apparatus for bringing a device online, and related equipment. Background Art

[0002] At present, the automation start of the campus needs to rely on L3 (three-layer) management switches, and the DHCP (Dynamic Host Configuration Protocol) relay configured on the device is used to enable the devices in the campus to obtain IP addresses and establish connections with the controller. However, as the campus supports more and more scenarios, such as single machine, stacking, MLAG (Multi-Chassis Link Aggregation, cross-device link aggregation group), etc., the requirements for L3 management switches are getting higher and higher, especially the requirement to support ECMP (Equal Cost Multi-path), which generally requires Leaf or higher devices to support, and the price of such devices is relatively high, which is difficult to meet in some projects, bringing great restrictions to the automatic online deployment.

[0003] However, the actual environment of some other branch campuses does not meet the conditions for deploying L3 switches. For example, the export routers, firewalls or core switches have been deployed at the export, and it is impossible to configure the Vlan1 and Vlan4094 gateways for device management on them, and configure the Vlan1 DHCP relay. In addition, the device management gateway is in the external device, requiring the connection interface trunk vlan 1 and Vlan 4094, and the second layer to the external device, and the complex configuration of STP (Spanning Tree Protocol). At this time, only semi-automation can be used, and complex Vxlan (Virtual Extensible Local Area Network) and BGP (Border Gateway Protocol) configurations need to be manually configured between spine-leaf, resulting in certain difficulties and limitations in project promotion.

[0033] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, rather than limiting the present application. The singular forms of "a", "said" and "the" used in the present application and claims are also intended to include plural forms, unless the context clearly indicates other meanings. 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.

[0034] 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, these information should not be limited to these terms. These terms are only used to distinguish the same type of information 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, in addition, the word "if" used may be interpreted as "at..." or "when..." or "in response to determination".

[0035] Currently, in the campus network, the principles for automatic device onboarding and management are as follows:

[0036] On the L3 management switch, first configure the gateway of the default Layer 2 connected VLAN (for example, VLAN 1) and the VLAN1 DHCP relay. Configure the gateway of the campus management network management VLAN (for example, VLAN 4094), and trunk VLAN 1 and VLAN 4094 on the L3 interface. Enable the STP protocol and configure STP ignore underlay VLAN.

[0037] The DHCP Server configuration option specifies the Websocket microservice address of the SDN controller.

[0038] The automated launch process of campus equipment is as follows:

[0039] 1. After the device is powered on, it executes the DHCP process of Vlan1, relays to the DHCP Server through the L3 management switch to obtain the Vlan1 address (IP address), and obtains the Websocket microservice address of the SDN controller based on the DHCP option field.

[0040] 2. The device actively initiates a connection to the Websocket microservice and establishes a Websocket channel with the SDN controller;

[0041] 3. The Websocket microservice reports the NE online event to the control component;

[0042] 4. The campus's SDN controller activates the network element and automatically sends basic configurations to the device through the Websocket channel, completing the automatic onboarding and management of the device.

[0043] However, in actual deployment, in addition to considering the cost of the L3 management switch, in branch offices in multi-campus scenarios, there are other devices (such as routers, firewalls, core switches, etc.) at the exit. Customers do not agree to configure DHCP relay services on such high-speed forwarding core devices, and require intercommunication with devices in the campus through Layer 2 ports, which requires STP configuration, so that external devices are added to the STP domain of the campus, which will have certain risks. Therefore, in some scenarios, semi-automatic online is generally used, and spine / leaf are manually online, which requires complex VXLAN-related configuration.

[0044] In order to solve the above technical problems, an embodiment of the present application proposes a technical solution based on a device in the campus network as a device online relay device, which realizes the automatic online of other devices in the campus network through the online relay device.

[0045] For example, see Figure 1As shown, it is a detailed flow chart of a device online method provided in an embodiment of the present application. The method is applied to a controller, and the method includes the following steps:

[0046] Step 100: After establishing a layer 3 connection with a target device in the network, determine whether the target device can be used as an online relay device for other devices in the network to go online.

[0047] In the embodiment of the present application, after establishing a layer 3 connection with a target device in the network, when determining whether the target device can be used as an online relay device for other devices in the network to go online, a preferred implementation method is:

[0048] After establishing a Websocket connection with the target device in the network, based on the device type information of the target device, determine whether the target device can be used as a relay device for other devices in the network to go online. If it is determined that the target device is the top-level device of the network, it is determined that the target device can be used as an online relay device for other devices in the network to go online.

[0049] In actual applications, the administrator selects a device (target device) and manually configures the device, specifically, configures the IP address of the device, and informs the device of the IP address of the controller through the command line, so that the device establishes a three-layer connection with the controller based on its own IP address and the IP address of the controller.

[0050] It should be noted that the IP address configured for the target device is an IP address in the address pool configured for the network in the DHCP server, and the IP address of the controller can be the IP address of the Websocket microservice of the controller.

[0051] In the embodiment of the present application, the target device is a Spine device, or a Leaf device.

[0052] That is to say, the campus network architecture can be an N-layer network architecture. For example, if the campus network architecture is a 2-layer network architecture, the top-level device is a Leaf device, and if the campus network architecture is a 3-layer network architecture, the top-level device is a Spine device.

[0053] In the embodiment of the present application, only the top-level device in the campus network can be used as a relay device for other devices in the network to go online.

[0054] Step 110: When it is determined that the target device can be used as an online relay device for other devices in the network to go online, the target device is managed.

[0055] In actual applications, after the controller establishes a three-layer network connection with the target device, the controller can discover the target device in the network topology of the network. When it is determined that the target device meets the conditions of being a relay device for other devices in the network to go online, the target device is managed.

[0056] Specifically, the controller is pre-configured with basic configurations of various types of devices. Managing target devices means obtaining the corresponding basic configuration based on the device type of the target device (such as Spine / Leaf device), and sending the basic configuration to the target device to enable the controller to manage the target device.

[0057] Step 120: Sending an online relay configuration to the target device, so that the target device can perform online operations for other devices in the network based on the online relay function.

[0058] After managing the target device, the controller sends the online relay configuration to the target device.

[0059] Specifically, in the embodiment of the present application, when sending the online relay configuration to the target device, a preferred implementation method is:

[0060] A first VLAN gateway configuration, a DHCP relay configuration, and a second VLAN gateway configuration are issued to the target device, wherein the first VLAN is a VLAN that is allowed by default in the network, and the second VLAN is a management VLAN of the network.

[0061] In combination with the above description, the first VLAN is Vlan 1, the second VLAN is Vlan 4094, the target device is configured as the gateway of Vlan 1, the target device is configured as a DHCP relay (relay), and the target device is configured as the gateway (management gateway) of Vlan 4094.

[0062] When other network devices in the campus network need to go online, the target device obtains the IP address corresponding to Vlan1 from the DHCP server. When obtaining the IP address, the specified option field of the DHCP response message also carries the IP address of the controller (the IP address of the controller's Websocket microservice). In this way, after other network devices are assigned IP addresses and obtain the IP address of the controller, they establish a three-layer network connection with the controller. The controller activates other network devices to be online and automatically sends basic configurations to the devices to be online through the Websocket channel, completing the automatic online management of the devices.
