技术领域technical field
本申请涉及参数配置技术领域，特别涉及一种二层设备配置方法、上层管理设备、下层设备、包括上层管理设备和下层设备的二层设备配置系统以及计算机可读存储介质。The present application relates to the technical field of parameter configuration, and in particular to a layer-2 device configuration method, an upper-layer management device, a lower-layer device, a layer-2 device configuration system including the upper-layer management device and the lower-layer device, and a computer-readable storage medium.
背景技术Background technique
当前情况下，网络设备在首次出厂后的第一次部署时，还未拥有分配给自己的IP等后续通信所需的配置信息，因此在创建集群和实现正常远程连接前，还需要对其进行必要参数的配置。In the current situation, when the network device is deployed for the first time after leaving the factory for the first time, it does not have the configuration information required for subsequent communication such as the IP assigned to it. Therefore, it needs to be configured before creating a cluster and realizing normal remote connection. Configuration of necessary parameters.
当一次需要配置的设备的数量较多时，面对巨大的工作量，一台台的进行配置的效率无疑是极低的，会耗费较多的时间成本和人力成本，因此寻找一种能够快速完成必要参数配置的方法是当前研究的重点。When the number of devices that need to be configured at one time is large, the efficiency of configuring each device is undoubtedly extremely low in the face of a huge workload, which will consume more time and labor costs. Therefore, it is necessary to find a device that can be quickly completed. The method of necessary parameter configuration is the focus of current research.
LLDP(Link Layer Discovery Protocol，链路层发现协议)是一个定义在802.1ab(当前广泛遵循的网络标准)中已被广泛应用的二层(链路层)协议，LLDP可以使得接入网络的设备可以将其主要的能力、管理地址、设备标识以及接口标识等信息发送给接入同一个局域网络的其它设备。当一个设备从网络中接收到其它设备的这些信息时，它就将这些信息以特定形式存储起来，这些存储起来的信息可用于发现设备的物理拓扑结构以及管理配置信息。LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol) is a layer 2 (link layer) protocol defined in 802.1ab (the current widely followed network standard) that has been widely used. LLDP can make devices connected to the network It can send information such as its main capability, management address, device ID, and interface ID to other devices connected to the same local area network. When a device receives the information from other devices in the network, it stores the information in a specific form, and the stored information can be used to discover the physical topology of the device and manage configuration information.
但LLDP仅被设计用于进行信息通告，用于通告一个设备的信息并获得其它设备的信息，进而得到相关的MIB(Management Information Base，管理信息库)信息。它不是一个配置、控制协议，标准LLDP协议无法对远端设备进行配置，只提供了可以用于建立网络拓扑以及后续用于管理和配置的所需信息。LLDP现今广泛应用于发现直连设备的信息，但在完成配置数量众多的下层设备必要的参数信息时，还需要使用其它的协议完成，更加繁琐和复杂。However, LLDP is only designed for information notification, for notifying information of one device and obtaining information of other devices, and then obtaining related MIB (Management Information Base, Management Information Base) information. It is not a configuration or control protocol. The standard LLDP protocol cannot configure remote devices, but only provides the required information for establishing network topology and subsequent management and configuration. LLDP is now widely used to discover the information of directly connected devices, but it needs to use other protocols to complete the configuration of the necessary parameter information for a large number of lower-layer devices, which is more cumbersome and complicated.
因此，如何克服现有LLDP协议无法用于配置二层设备的技术缺陷是本领域技术人员亟待解决的问题。Therefore, how to overcome the technical defect that the existing LLDP protocol cannot be used to configure a layer-2 device is an urgent problem to be solved by those skilled in the art.

实施例一Embodiment one
以下结合图1，图1为本申请实施例提供的一种应用于上层管理设备的二层设备配置方法的流程图，其具体包括以下步骤：In conjunction with FIG. 1 below, FIG. 1 is a flow chart of a layer-2 device configuration method applied to an upper-layer management device provided by an embodiment of the present application, which specifically includes the following steps:
S101：向各下层设备广播LLDP搜索发现报文，以使各下层设备返回包含自身MAC地址的LLDP搜索响应报文；S101: Broadcast an LLDP search discovery message to each lower-layer device, so that each lower-layer device returns an LLDP search response message containing its own MAC address;
上层管理设备首先将LLDP搜索发现报文广播给所有与其建立了物理连接关系的各下层设备，以期收到各下层设备对接收到的LLDP搜索发现报文做出响应返回的包含自身MAC地址的LLDP搜索响应报文。The upper-layer management device first broadcasts the LLDP discovery message to all lower-layer devices with which it has established a physical connection relationship, in order to receive the LLDP packet containing its own MAC address returned by each lower-layer device in response to the received LLDP search and discovery message. Search response message.
需要说明的是，基于标准LLDP协议的功能设计，搜索发现存在的设备并反馈一些信息是其主要功能，本申请的重点并非为提供一种利用LLDP协议发现下层设备的方法，本步骤的实现过程已被本领域技术人员所熟知，在此不再赘述。It should be noted that based on the functional design of the standard LLDP protocol, the main function is to search for existing devices and feed back some information. The focus of this application is not to provide a method for discovering lower-layer devices using the LLDP protocol. The implementation process of this step It is well known by those skilled in the art and will not be repeated here.
S102：响应于接收到的LLDP搜索响应报文，提取得到各下层设备的MAC地址，并为各MAC地址分配对应的待配置信息，得到包含MAC地址和对应待配置信息的各配置识别数据；S102: In response to the received LLDP search response message, extract the MAC address of each lower-layer device, and allocate corresponding information to be configured for each MAC address, and obtain each configuration identification data including the MAC address and the corresponding information to be configured;
在S101的基础上，本步骤旨在上层管理设备从接收到的LLDP搜索响应报文中提取出各下层设备的MAC地址，以便根据与每个下层设备唯一对应的MAC地址为其分配对应的待配置信息，得到各配置识别数据，即每个配置识别数据中包含一个MAC地址和将要配置在该MAC地址对应的下层设备的配置信息，两者之间存在对应关系，以便各下层设备从众多对配置识别数据中寻找到与自身MAC地址相同的MAC地址，并在确定到相同的MAC地址，也就能够得到成对出现的待配置信息。On the basis of S101, this step aims at the upper layer management device to extract the MAC address of each lower layer device from the received LLDP search response message, so as to allocate corresponding waiting time for each lower layer device according to the MAC address uniquely corresponding to each lower layer device. Configuration information, each configuration identification data is obtained, that is, each configuration identification data contains a MAC address and the configuration information of the lower-layer device to be configured corresponding to the MAC address, and there is a correspondence between the two, so that each lower-layer device can learn from many Finding the same MAC address as its own MAC address in the configuration identification data, and determining the same MAC address, it is possible to obtain the information to be configured in pairs.
如何为各MAC地址分配对应的待配置信息的方式有很多，例如当各下层设备的功能、作用一致时，可随机为各MAC分配作用、功能相同的待配置信息，当然，诸如IP地址等唯一参数还需要按照其它分配规则来进行分配，不应存在将同一IP地址分配给多个下层设备的情况；也可以按照MAC地址的顺序、所属号段等进行分配等等，此处并不做具体限定，本领域技术人员可以根据本步骤的思想结合不同场景的要求灵活选择。There are many ways how to allocate corresponding information to be configured for each MAC address. For example, when the functions and functions of each lower-layer device are the same, the information to be configured with the same role and function can be randomly assigned to each MAC address. Of course, unique information such as IP addresses The parameters also need to be allocated according to other allocation rules. There should be no situation where the same IP address is allocated to multiple lower-level devices; it can also be allocated according to the order of the MAC address, the number segment, etc., etc., which will not be specified here. Those skilled in the art can flexibly choose according to the idea of this step in combination with the requirements of different scenarios.
需要说明的是，本申请各步骤中出现的下层设备均为新接入集群的设备，即空白节点，仅通过物理连接线与上层管理设备，在真正上线使用前还需要对他们进行一些配置，例如为其分配相应的IP地址、上线所需参数、编号等等。由于各空白节点在此种情况下具有的一个有力区别于其它空白节点的特征数据就是MAC地址，虽然其它诸如机器码的特征数据也可以使用，但不如MAC地址更易获取和识别度高。It should be noted that the lower-layer devices appearing in each step of this application are all devices newly connected to the cluster, that is, blank nodes. They are only connected to the upper-layer management devices through physical connection lines. Some configurations need to be performed on them before they are actually used online. For example, assign the corresponding IP address, the parameters required for going online, the serial number, and so on. Because each blank node in this case has a feature data that is powerfully different from other blank nodes is the MAC address. Although other feature data such as machine codes can also be used, it is not as easy to obtain and has a high degree of recognition as the MAC address.
S103：将各配置识别数据作为新增字段添加进LLDP协议报文的自定义字段，得到LLDP配置报文；S103: adding each configuration identification data as a new field into a custom field of the LLDP protocol message to obtain the LLDP configuration message;
在S102的基础上，本步骤旨在将得到的各配置识别数据作为新增字段添加进LLDP协议报文的自定义字段，以得到包含配置识别数据的LLDP配置报文。On the basis of S102, this step aims to add the obtained configuration identification data as new fields into the custom fields of the LLDP protocol message, so as to obtain the LLDP configuration message including the configuration identification data.
受到LLDP协议报文最大长度的限制，有可能无法一次性将所有配置识别数据都放入一个LLDP配置报文，根据配置识别数据的长度可设定合适的数量，即通过多个LLDP配置报文先后将所有配置识别数据全部广播出去。Due to the limitation of the maximum length of the LLDP protocol message, it may not be possible to put all the configuration identification data into one LLDP configuration message at one time, and an appropriate number can be set according to the length of the configuration identification data, that is, through multiple LLDP configuration messages All configuration identification data are broadcast successively.
请结合图8所提供的LLDP协议报文的一种标准格式，首先对最上层的各字段的含义解释如下：Please combine a standard format of the LLDP protocol message provided in Figure 8, and first explain the meaning of each field at the top layer as follows:
DA：目的地址；DA: destination address;
SA：源地址，为源端口地址或源设备地址(如有源端口地址则用原端口地址，否则用源设备地址)；SA: source address, which is the source port address or source device address (if there is a source port address, use the original port address, otherwise use the source device address);
Type：帧类型，为0x88CC；Type: frame type, which is 0x88CC;
Data：包含真正想要传输的数据，为LLDPDU，即LLDPPDU是LLDP的有效负载，用于承载要发送的消息；Data: Contains the data you really want to transmit, which is LLDPDU, that is, LLDPPDU is the payload of LLDP, which is used to carry the message to be sent;
FCS：帧检验序列。FCS: Frame Check Sequence.
接着，如中层对LLDPDU的拆分图所示，LLDPDU采用了TLV的格式，即type+length+value的格式，type表示TLV的类型，length是以字节为单位的TLV的长度，value是该TLV的值。其中Chassis ID TLV、Port ID TLV、Time To Live TLV以及End Of LLDPDU TLV是强制的，一个LLDPDU必须包含的部分，除此之外在TLV Time To Live TLV和End Of LLDPDU TLV之间可以包含0个到多个可选的其它TLV(即自定义TLV，也就是本步骤所描述的自定义字段)。Next, as shown in the splitting diagram of the LLDPDU in the middle layer, the LLDPDU adopts the format of TLV, that is, the format of type+length+value, type indicates the type of TLV, length is the length of the TLV in bytes, and value is the The value of the TLV. Among them, Chassis ID TLV, Port ID TLV, Time To Live TLV and End Of LLDPDU TLV are mandatory, a part that must be included in an LLDPDU, in addition, 0 can be included between TLV Time To Live TLV and End Of LLDPDU TLV to multiple optional other TLVs (that is, custom TLVs, that is, the custom fields described in this step).
最后，以Port ID TLV为例，通过最下层拆分图对TLV具体组成进行描述：Finally, taking the Port ID TLV as an example, the specific composition of the TLV is described through the bottom-level split diagram:
TLV是组成LLDPDU的单元，每个TLV都代表一个信息。LLDPDU的TLV可以分为两大类：TLV is the unit that makes up LLDPDU, and each TLV represents a piece of information. The TLV of LLDPDU can be divided into two categories:
其中一类被认为是网络管理的基础的TLV集合，所有的LLDP实现都需要支持；另一类则是组织定义的TLV扩展集和，包括802.1组织定义TLV、802.3组织定义TLV以及其他组织定义的TLV。该类TLV用于增强对网络设备的管理，可根据实际需要选择是否在LLDPDU中发送。One of them is considered to be the basic TLV set of network management, and all LLDP implementations need to support it; the other is the TLV extension set defined by the organization, including 802.1 organization-defined TLV, 802.3 organization-defined TLV and other organization-defined TLV. This type of TLV is used to enhance the management of network devices, and you can choose whether to send it in the LLDPDU according to actual needs.
请参见图9，图9左侧为常见TLV的类型域的定义及分配图，包含了常规TLV的名称和使用类型，右侧则是本申请在预留的自定义区域给出的一种新增TLV字段的实现方式。其中，Mandatory表示对应类型的TLV为强制存在的，Optional则表示可选的，图5右侧则表示本申请在生成包含配置识别数据的LLDP配置报文时将新增的TLV字段设定为Mandatory。Please refer to Figure 9. The left side of Figure 9 shows the definition and allocation of common TLV type domains, including the name and usage type of conventional TLVs, and the right side shows a new TLV in the reserved custom area Add the implementation of the TLV field. Among them, Mandatory indicates that the TLV of the corresponding type is mandatory, and Optional indicates that it is optional. The right side of Figure 5 indicates that the application sets the newly added TLV field as Mandatory when generating the LLDP configuration message containing the configuration identification data .
图8和图9中其余使用英文描述的内容均为LLDP协议中的具体内容，其含义已被本领域技术人员所熟知，亦非本申请的重点描述对象，在此不再赘述。The rest of the contents described in English in Fig. 8 and Fig. 9 are the specific contents in the LLDP protocol, and their meanings are well known by those skilled in the art, and they are not the key description objects of this application, and will not be repeated here.
S104：向各下层设备广播LLDP配置报文，以使各下层设备利用LLDP配置报文中包含的与自身MAC地址对应的待配置信息完成配置。S104: Broadcast the LLDP configuration message to each lower-layer device, so that each lower-layer device completes configuration by using the information to be configured corresponding to its own MAC address contained in the LLDP configuration message.
在S103的基础上，本步骤旨在将包含配置识别数据的LLDP配置报文广播给所有与上层管理设备建立了连接的下层设备，以使各下层设备利用LLDP配置报文中包含的与自身MAC地址对应的待配置信息完成配置。On the basis of S103, this step aims to broadcast the LLDP configuration message containing the configuration identification data to all lower-layer devices that have established a connection with the upper-layer management device, so that each lower-layer device uses the LLDP configuration message contained in the LLDP configuration message and its own MAC The information to be configured corresponding to the address is configured.
当上层管理设备先后发送了多个包含不同对配置识别数据的LLDP配置报文时，各下层设备通常会按照接收到的LLDP配置报文的先后顺序依次寻找那个包含与自身MAC地址相同的MAC地址的配置识别数据，以便根据成对的关系确定分配给自己的待配置信息。When the upper-layer management device sends multiple LLDP configuration packets containing different pairs of configuration identification data, each lower-layer device will usually search for the MAC address that contains the same MAC address as its own according to the order of the received LLDP configuration packets. The configuration identification data, so as to determine the information to be configured assigned to itself according to the paired relationship.
一种包括但不限于的待配置信息的配置方式：调用CLI命令将待配置信息配置于自身。其中，CLI是Command-Line Interface的英文缩写，中文名为命令行界面。A configuration method including but not limited to the information to be configured: call the CLI command to configure the information to be configured on itself. Among them, CLI is the English abbreviation of Command-Line Interface, and the Chinese name is Command Line Interface.
进一步的，如对图8描述中的DA表示的目的地址，在LLDP协议中，目的地址根据穿透能力的不同存在三类，一类无法穿透不直接相连的设备，一类可穿透同一局域网内的路由器和交换机，而最后一类则还可穿透局域网，通常情况下为实现对处于同一局域网内的集群所有设备完成搜索发现和配置，会选择其中一类可穿透交换机的目的地址，具体的，该目的地址为：01-80-C2-00-00-03。Further, as for the destination address represented by DA in the description of Figure 8, in the LLDP protocol, there are three types of destination addresses according to different penetration capabilities, one type cannot penetrate devices that are not directly connected, and the other type can penetrate the same Routers and switches in the local area network, and the last type can also penetrate the local area network. Usually, in order to realize the search, discovery and configuration of all devices in the cluster in the same local area network, one of the destination addresses of the penetrable switches will be selected. , specifically, the destination address is: 01-80-C2-00-00-03.
更进一步的，在下层设备根据接收到的LLDP配置报文完成将匹配的待配置信息配置在自身后，还可以向上层管理设备反馈一个响应信号，以使上层管理设备明确该下层设备的参数配置状态，以便于后续使用。Furthermore, after the lower-layer device configures the matching information to be configured on itself according to the received LLDP configuration message, it can also feed back a response signal to the upper-layer management device, so that the upper-layer management device can clarify the parameter configuration of the lower-layer device state for subsequent use.
基于上述技术方案，本申请实施例提供的一种应用于上层管理设备的二层设备配置方法，上层管理设备从下层设备处获取出厂即具备且唯一的MAC地址，并为这些MAC地址分配相应的待配置信息以得到成对的配置识别信息，同时在原有LLDP协议报文构成的基础上，将配置识别信息加入自定义字段以生成并广播包含待配置信息的LLDP配置报文，使得各下层设备根据与自身MAC地址对应的待配置信息完成相应的配置。该方法在允许范围内对原有标准LLDP协议报文进行改造，使其可以携带待配置信息，无需使用其它协议即可完成待配置信息的分发和配置，代码复杂度更低。Based on the above technical solution, the embodiment of the present application provides a layer-2 device configuration method applied to the upper-layer management device. The upper-layer management device obtains the unique MAC addresses that are available at the factory from the lower-layer device, and assigns corresponding MAC addresses to these MAC addresses. Information to be configured to obtain paired configuration identification information. At the same time, based on the composition of the original LLDP protocol message, the configuration identification information is added to the custom field to generate and broadcast the LLDP configuration message containing the information to be configured, so that each lower layer device Complete the corresponding configuration according to the information to be configured corresponding to its own MAC address. This method transforms the original standard LLDP protocol message within the allowable range, so that it can carry the information to be configured, and the distribution and configuration of the information to be configured can be completed without using other protocols, and the code complexity is lower.
