技术领域technical field
本申请实施例涉及通信传输领域，特别涉及一种跨设备链路聚合的网管方法、***、交换机及存储介质。The embodiments of the present application relate to the field of communication transmission, and in particular to a network management method, system, switch and storage medium for cross-device link aggregation.
背景技术Background technique
目前普遍的跨设备链路聚合交换机的网管方法是：将跨设备链路聚合交换机***的两台交换机，上游汇聚节点，以及网管服务器，分别配置一个网管单独使用的三层网络。在这个单独使用的三层网络中，汇聚节点作为网关，而跨设备链路聚合交换机***不再认为是一个聚合链路，而是多个单独的交换机，各自有不同的IP地址。通过三层网络的路由，网管服务器可以对跨设备链路聚合交换机***的两台交换机分别进行管理操作。At present, the common network management method of the cross-device link aggregation switch system is: configure two switches of the cross-device link aggregation switch system, the upstream aggregation node, and the network management server, respectively, to configure a three-layer network used solely by the network management. In this single-use three-layer network, the aggregation node is used as a gateway, and the cross-device link aggregation switch system is no longer considered as an aggregation link, but multiple independent switches, each with a different IP address. Through the routing of the three-layer network, the network management server can manage and operate the two switches of the cross-device link aggregation switch system respectively.
由此可见，为了保证跨设备链路聚合交换机***可以被正确的网管，必须要额外配置一套三层网络，专门用于网管。然而三层网络的配置复杂，需要重新配置一套专门用于网管的三层网络，打通分别到跨设备链路聚合交换机***的两台交换机的网管通道。并且由于需要配置专门用于网管的三层网络，因此消耗了额外的IP地址、vlan id；增加了维护的复杂度，除了维护业务的网络之外，还要在设备上维护一套网管的网络。It can be seen that in order to ensure that the cross-device link aggregation switch system can be managed correctly, an additional layer-3 network must be configured for network management. However, the configuration of the three-layer network is complicated. It is necessary to reconfigure a set of three-layer network specially used for network management, and open up the network management channels to the two switches of the cross-device link aggregation switch system. And because it is necessary to configure a three-tier network specially used for network management, additional IP addresses and vlan ids are consumed; the complexity of maintenance is increased. In addition to maintaining the business network, a set of network management networks must be maintained on the device .

本申请的一个实施方式涉及一种跨设备链路聚合的网管方法，应用于跨设备链路聚合交换机***中的交换机，各交换机分别设有跨设备链路聚合交换机***IP的子IP地址。具体流程如图1所示。An embodiment of the present application relates to a network management method for cross-device link aggregation, which is applied to switches in the cross-device link aggregation switch system, and each switch is respectively provided with a sub-IP address of the cross-device link aggregation switch system IP. The specific process is shown in Figure 1.
步骤101，接收网管服务器通过汇聚节点发送的用于操作交换机的请求，请求携带操作对应的目标交换机的子IP地址； Step 101, receiving the request for operating the switch sent by the network management server through the aggregation node, and the request carries the sub-IP address of the target switch corresponding to the operation;
步骤102，若目标交换机的子IP地址为跨设备链路聚合交换机***中的另一交换机的子IP地址，则将请求通过第一链路转发至另一交换机，其中，第一链路为当前交换机与另一交换机之间的通信链路。 Step 102, if the sub-IP address of the target switch is the sub-IP address of another switch in the inter-device link aggregation switch system, forward the request to another switch through the first link, wherein the first link is the current A communication link between a switch and another switch.
本实施例中，利用当前跨设备链路聚合交换机***中各交换机的子IP，以及交换机之间的第一交换链路进行信息交互，可以使得网管服务器在不需要增加额外配置的情况下，直接对跨设备链路聚合交换机***的各台交换机设备实行网管，不需要增加任何网络配置即可对跨设备链路聚合***进行管理，从而降低网络维护的复杂度，节约网络资源，同时提高了网络管理的便捷程度，提升了网络的易用性，节约了网络配置成本。In this embodiment, the sub-IP of each switch in the current inter-device link aggregation switch system and the first switching link between switches are used for information exchange, so that the network management server can directly Network management is implemented for each switch device of the cross-device link aggregation switch system, and the cross-device link aggregation system can be managed without adding any network configuration, thereby reducing the complexity of network maintenance, saving network resources, and improving network performance. The convenience of management improves the usability of the network and saves the cost of network configuration.
下面对本实施方式的跨设备链路聚合的网管方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。The implementation details of the network management method for cross-device link aggregation in this embodiment will be described in detail below. The following content is only implementation details provided for easy understanding, and is not necessary for implementing this solution.
在步骤101中，接收网管服务器通过汇聚节点发送的用于操作交换机的请求，请求携带操作对应的目标交换机的子IP地址。In step 101, a request for operating a switch sent by a network management server through an aggregation node is received, and the request carries a sub-IP address of a target switch corresponding to the operation.
一般情况下，网管服务器接入含有跨设备链路聚合交换机***的网络时，接入的位置在汇聚节点侧，从汇聚节点侧的角度看跨设备链路聚合交换机***，其数据请求的转发都是负载分担的，而网管服务器对跨设备链路聚合交换机***进行网管的时候，如果要针对其中某一台交换机进行管理，数据请求在汇聚 节点可能会被负载分担，也就是经过汇聚节点的计算处理后，数据请求不一定会发送到目标交换机，因此会出现网管断链的问题。在本实施方式中，跨设备链路聚合交换机***中的交换机不仅向外部设备展示该***的对外IP地址，还展示各交换机的子IP地址，用于明确请求的目标交换机。在此基础上，网管服务器通过汇聚节点发送的请求中会携带目标交换机的子IP地址，用于明确该请求的目标交换机。Generally, when the network management server accesses a network with a cross-device link aggregation switch system, the access location is on the side of the aggregation node. From the perspective of the aggregation node side, the cross-device link aggregation switch system has no data forwarding. It is load sharing, and when the network management server performs network management on the cross-device link aggregation switch system, if one of the switches is to be managed, the data request may be load shared at the aggregation node, that is, after the calculation of the aggregation node After processing, the data request may not be sent to the target switch, so there will be a problem of network management link disconnection. In this embodiment, the switches in the cross-device link aggregation switch system not only display the external IP address of the system to external devices, but also display the sub-IP addresses of each switch, which is used to clarify the target switch of the request. On this basis, the request sent by the network management server through the aggregation node will carry the sub-IP address of the target switch to specify the target switch of the request.
在步骤102中，根据当前交换机的子IP地址判断目标交换机是否为当前交换机；若目标交换机的子IP地址为跨设备链路聚合交换机***中的另一交换机的子IP地址，则将请求通过第一链路转发至另一交换机，其中，第一链路为当前交换机与另一交换机之间的通信链路。In step 102, judge whether the target switch is the current switch according to the sub-IP address of the current switch; A link is forwarded to another switch, wherein the first link is a communication link between the current switch and another switch.
交换机在从汇聚节点接收到请求后，根据接收到请求的当前交换机的子IP地址和请求中携带的目标交换机的子IP地址，判断当前交换机是否为请求的目标交换机。即，若当前交换机的子IP地址与请求中携带的目标交换机的子IP地址一致，则表示接收到请求的当前交换机就是请求的目标交换机，则对请求进行对应处理或响应即可。在一个例子中，当前交换机在收到请求，并由当前交换机的中央处理器(Central processing unit，CPU)判断当前交换机为目标交换机时，从请求中获取请求的源MAC(Media Access Control，媒体介入控制层)地址，对请求进行处理或应答，回复至所述请求的源MAC地址。After the switch receives the request from the aggregation node, it judges whether the current switch is the target switch of the request according to the sub-IP address of the current switch that receives the request and the sub-IP address of the target switch carried in the request. That is, if the sub-IP address of the current switch is consistent with the sub-IP address of the target switch carried in the request, it means that the current switch that received the request is the target switch of the request, and the request can be processed or responded accordingly. In one example, when the current switch receives the request and the central processing unit (Central processing unit, CPU) of the current switch determines that the current switch is the target switch, it obtains the source MAC (Media Access Control, media intervention) from the request. control layer) address, process or respond to the request, and reply to the source MAC address of the request.
在一个例子中，第一链路可以为当前交换机与另一交换机(目标交换机)之间的peer-link链路。并不需要新建通信链路，也不需要新增相应的后续维护过程。In an example, the first link may be a peer-link link between the current switch and another switch (target switch). There is no need to create a new communication link, nor does it need to add a corresponding follow-up maintenance process.
在一个例子中，跨设备链路聚合的网管方法还包括：若当前交换机从第一链路接收到所述请求，则当前交换机禁止更新请求的MAC地址与传输端口的对应关系，在一些例子中，可定义为不学习MAC地址。请求中的MAC地址是交换机对请求进行响应的目标地址，禁止更新请求的MAC地址与传输端口的对应关系，则请求中的MAC地址与传输端口的对应关系不会被多次更新或覆盖，也就是说在第一链路中进行一次转发之后，目标交换机仍保留MAC地址与上行接口之间的对应关系，从而避免MAC漂移现象，维持MAC地址表项的正常使用。若发生MAC漂移现象，则是指由于更新了MAC地址对应的传输端 口，则目标交换机会存储MAC地址与第一链路端口的对应关系，在下次收到汇聚节点向发送至目标交换机的请求后，会按照MAC地址与第一链路端口的对应关系进行回复会或处理，处理后会将MAC地址与上行接口的对应关系覆盖原对应关系，反复多次会导致传输路径混乱，有碍于本***中的信息回复响应。在本例子中，由于禁止更新请求中MAC地址与传输端口的对应关系，保证响应信息的目标地址正确以及传输路径稳定，不会由于MAC地址漂移而传输路径混乱，从而保证跨设备链路聚合设备中的信息传输通路正常。In one example, the network management method for inter-device link aggregation further includes: if the current switch receives the request from the first link, the current switch is prohibited from updating the corresponding relationship between the MAC address of the request and the transmission port, in some examples , which can be defined as not learning MAC addresses. The MAC address in the request is the target address for the switch to respond to the request. It is forbidden to update the corresponding relationship between the MAC address in the request and the transmission port. That is to say, after a forwarding is performed on the first link, the target switch still retains the corresponding relationship between the MAC address and the uplink interface, so as to avoid the phenomenon of MAC drift and maintain the normal use of the MAC address entry. If the phenomenon of MAC drift occurs, it means that the transmission port corresponding to the MAC address has been updated, and the target switch will store the corresponding relationship between the MAC address and the first link port. , it will reply or process according to the corresponding relationship between the MAC address and the first link port. After processing, the corresponding relationship between the MAC address and the uplink interface will overwrite the original corresponding relationship. Repeating many times will lead to confusion in the transmission path, which hinders the The information in the system returns the response. In this example, because the corresponding relationship between the MAC address and the transmission port in the update request is prohibited, the target address of the response information is correct and the transmission path is stable, and the transmission path will not be confused due to MAC address drift, thereby ensuring that the cross-device link aggregation device The information transmission path in is normal.
在一个例子中，跨设备链路聚合的网管方法还包括：若所述当前交换机从所述第一链路接收到所述请求，则所述当前交换机禁止所述请求进行再次传送，或在一些例子中可定义为各交换机存在广播抑制。即，相同的数据仅允许由交换机设备发送一次，接收到的请求是由交换机发送时，不允许进行再次传送。以避免请求回环至转发请求的交换机，避免请求回溯至汇聚节点同时也避免请求传送至下游设备，减少不必要的传输资源及处理资源的浪费，提高本跨设备链路聚合交换机***的数据处理质量和速率。In an example, the network management method for cross-device link aggregation further includes: if the current switch receives the request from the first link, the current switch prohibits the request from being retransmitted, or in some In the example, it can be defined that each switch has broadcast suppression. That is, the same data is only allowed to be sent by the switch device once, and when the received request is sent by the switch, retransmission is not allowed. Avoid request loopback to the switch forwarding the request, avoid request backtracking to the aggregation node and avoid sending the request to the downstream device, reduce unnecessary transmission resources and waste of processing resources, and improve the data processing quality of the cross-device link aggregation switch system and rate.
在另一个例子中，跨设备链路聚合的网管方法，还包括：若当前交换机从第一链路接收到请求，则当前交换机从当前交换机的上行接口将请求的响应消息传输至所述汇聚节点；其中，上行接口为所述当前交换机与所述汇聚节点进行信息交互的接口。即，若当前交换机接收到的请求是汇聚节点直接发送的，则在当前交换机的上行接口进行响应回复；若当前交换机的请求是从其他交换机转发过来的，则同样在当前交换机的上行接口进行响应回复。规定响应消息的回复路径，保证响应消息能够在最短距离对请求进行回应，即直接通过交换机的上行接口向汇聚节点进行发送，减少响应时间，提高本跨设备链路聚合交换机***的数据处理速率。In another example, the network management method for inter-device link aggregation further includes: if the current switch receives a request from the first link, the current switch transmits a request response message to the aggregation node from the uplink interface of the current switch ; Wherein, the uplink interface is an interface for information exchange between the current switch and the aggregation node. That is, if the request received by the current switch is directly sent by the aggregation node, it will reply on the uplink interface of the current switch; if the request of the current switch is forwarded from other switches, it will also respond on the uplink interface of the current switch Reply. The reply path of the response message is specified to ensure that the response message can respond to the request at the shortest distance, that is, it is sent directly to the aggregation node through the uplink interface of the switch, reducing the response time and improving the data processing rate of the cross-device link aggregation switch system.
另外，第一链路可以为peer-link链路，请求包括地址解析协议(Address Resolution Protocol，ARP)请求。In addition, the first link may be a peer-link link, and the request includes an Address Resolution Protocol (Address Resolution Protocol, ARP) request.
在一个实现过程中，从网管服务器发出ARP请求访问跨设备链路聚合交换机***其中某一台交换机的时候，如果这个ARP请求被汇聚节点负载均衡到了另外一台跨设备链路聚合的交换机上，则此请求会因为无法获得正确的应答而被丢弃，造成网管服务器的ARP无法被正确响应。而采用本实施方式，将ARP 请求报文在peer-link链路的端口上通过访问控制或其他方法放行，使得无论ARP报文被负载均衡到跨设备链路聚合交换机***的哪一侧的交换机上，均可通过peer-link链路到达目标侧；并通过原网络中存在的交换机具有的子IP地址进行对交换机的识别和判定，不需要增加新的网络架构，减少资源占用和后期的维护需求。同时，通过广播抑制可以使得此ARP报文不会再被环回到汇聚节点上。为了防止出现交换机与汇聚节点的上行接口和peer-link链路的端口之间出现MAC漂移，peer-link链路的端口口上保持MAC地址不学习的状态。另外，目标交换机的CPU收到此ARP报文之后，无论是从交换机的上行接口收到还是从peer-link链路的端口收到，均从交换机的上行接口进行ARP应答。In an implementation process, when an ARP request is sent from the network management server to access one of the switches in the cross-device link aggregation switch system, if the ARP request is load-balanced to another cross-device link aggregation switch by the aggregation node, Then this request will be discarded because the correct response cannot be obtained, causing the ARP of the network management server to be unable to be correctly responded. However, in this implementation mode, the ARP request message is released on the port of the peer-link link through access control or other methods, so that no matter which side of the inter-device link aggregation switch system the ARP message is load-balanced above, can reach the target side through the peer-link link; and identify and judge the switch through the sub-IP address of the switch existing in the original network, without adding a new network architecture, reducing resource occupation and later maintenance need. At the same time, broadcast suppression can prevent the ARP message from being looped back to the sink node. In order to prevent MAC drift between the uplink interface of the switch and the aggregation node and the port of the peer-link link, the port of the peer-link link remains in the state of not learning the MAC address. In addition, after the CPU of the target switch receives the ARP message, whether it is received from the uplink interface of the switch or from the port of the peer-link link, it will send an ARP reply through the uplink interface of the switch.
通过本实施方式的方法，网管服务器对跨设备链路聚合交换机***的某个交换机发送的ARP请求，无论被汇聚节点发往哪一侧，都可以正确的转发到需要应答的交换机设备上，并且在整个过程中，不会出现任何对跨设备链路聚合交换机***有异常干扰的表项和转发行为。在不需要增加额外配置的情况下，直接对跨设备链路聚合交换机***的各台交换机设备进行网管，提高了网络管理的便捷程度，提升了网络的易用性，节约了网络配置成本。Through the method of this embodiment, the ARP request sent by the network management server to a switch in the cross-device link aggregation switch system can be correctly forwarded to the switch device that needs to be answered no matter which side is sent by the aggregation node, and During the whole process, there will not be any table entries and forwarding behaviors that interfere abnormally with the inter-device link aggregation switch system. Without adding additional configuration, the network management of each switch device of the cross-device link aggregation switch system is directly performed, which improves the convenience of network management, improves the ease of use of the network, and saves network configuration costs.

本申请的一个实施方式涉及一种跨设备链路聚合的网管***。如图2所示，包括：An embodiment of the present application relates to a network management system for inter-device link aggregation. As shown in Figure 2, including:
网管服务器，与网管服务器通信连接的汇聚节点，与汇聚节点通信连接的跨设备链路聚合交换机***，跨设备链路聚合交换机***包括至少两个交换机，各交换机分别设有跨设备链路聚合交换机***IP的子IP地址；A network management server, an aggregation node communicated with the network management server, an inter-device link aggregation switch system communicatively connected with the aggregation node, the inter-device link aggregation switch system includes at least two switches, and each switch is respectively equipped with an inter-device link aggregation switch The sub-IP address of the system IP;
网管服务器201，用于通过汇聚节点向跨设备链路交换机***中的交换机发送用于操作交换机的请求，请求中包含操作的目标交换机的子IP地址；The network management server 201 is used to send a request for operating the switch to the switch in the cross-device link switch system through the aggregation node, and the request includes the sub-IP address of the target switch to be operated;
汇聚节点202，用于向跨设备链路聚合交换机***中的交换机转发请求；The aggregation node 202 is configured to forward requests to switches in the inter-device link aggregation switch system;
交换机203，用于接收网管服务器通过汇聚节点发送的请求，若目标交换机的子IP地址为跨设备链路聚合交换机***中的另一交换机的子IP地址，则 将请求通过第一链路转发至另一交换机，其中，第一链路为当前交换机与另一交换机之间的通信链路。The switch 203 is used to receive the request sent by the network management server through the aggregation node. If the sub-IP address of the target switch is the sub-IP address of another switch in the cross-device link aggregation switch system, the request is forwarded to Another switch, wherein the first link is a communication link between the current switch and another switch.
在一个例子中，交换机203还用于响应请求时通过上行接口传送至汇聚节点202。In an example, the switch 203 is also used to transmit the response to the aggregation node 202 through an uplink interface.
在一个例子中，当汇聚节点将请求转发至目标交换机的情况下，例如，网管服务器访问跨设备链路聚合交换机***的某台交换机，将请求报文广播发送到汇聚节点；汇聚节点通过负载均衡运算，直接将此报文发给正确的需要应答的交换机；需要应答的交换机将此请求报文在CPU进行处理，并在与汇聚节点相连的上行接口学习网管服务器的MAC地址，对请求报文进行应答，该应答信息从上行接口发送到汇聚节点，汇聚节点将该应答发送给网管服务器。在另一个例子中，具体地，网管服务器C需要管理交换机A，网管服务器将ARP请求报文广播发送到汇聚节点G；汇聚节点G通过负载均衡运算，将ARP请求负载均衡发往交换机A；交换机A从A1口收到此ARP报文，将此ARP上送交换机A的CPU进行处理，A1口学习网管服务器C的MAC地址，并对网管服务器ARP应答，该应答数据从A1发送到汇聚节点G；汇聚节点G将ARP应答发送给网管服务器C。由此可以建立网管通路。In one example, when the aggregation node forwards the request to the target switch, for example, the network management server accesses a certain switch in the cross-device link aggregation switch system, and broadcasts the request message to the aggregation node; operation, and directly send the message to the correct switch that needs to respond; the switch that needs to respond processes the request message in the CPU, and learns the MAC address of the network management server on the uplink interface connected to the aggregation node, and responds to the request message Response, the response information is sent from the uplink interface to the aggregation node, and the aggregation node sends the response to the network management server. In another example, specifically, the network management server C needs to manage the switch A, and the network management server broadcasts the ARP request message to the aggregation node G; the aggregation node G sends the ARP request load balancing to the switch A through a load balancing operation; A receives the ARP message from port A1, sends the ARP message to the CPU of switch A for processing, port A1 learns the MAC address of network management server C, and responds to the ARP of network management server, and the response data is sent from A1 to aggregation node G ; The aggregation node G sends the ARP response to the network management server C. In this way, a network management channel can be established.
在一个例子中，当汇聚节点将请求转发至非目标交换机的情况下，例如，网管服务器访问跨设备链路聚合交换机***的某台交换机，将请求报文广播发送到汇聚节点；汇聚节点通过负载均衡运算，将此报文发给跨设备链路聚合交换机***中非目标交换机的交换机；该交换机将此请求报文在CPU进行处理，CPU发现此请求报文并非请求自己，则将其通过第一链路转发给需要应答的目标交换机；目标交换机将此请求报文在CPU进行处理，同时广播隔离功能生效，不再转发此请求报文，并且上不学习此请求报文的MAC地址；将此请求报文的MAC地址写入上连口中，并对网管服务器进行应答，该应答数据从上行接口发送到汇聚节点；汇聚节点将该应答发送给网管服务器。在另一个例子中，具体地，网管服务器C需要管理交换机A，网管服务器C将ARP请求报文广播发送到汇聚节点G；汇聚节点G通过负载均衡运算，将ARP请求负载均衡发往交换机B；交换机B将此ARP上送交换机B的CPU进行处理，交换机B的CPU发现此ARP并非请求自己，则通过peer-link链路，送往需要回应的目 标交换机A，交换机A将此ARP上送交换机A的CPU进行处理，同时广播隔离功能生效，交换机A不再转发此ARP报文，并且不学习此ARP报文的MAC地址；交换机A将此ARP在CPU进行处理后，将此ARP报文的MAC地址写入上行接口A1中，并对网管服务器C进行ARP报文的应答，该应答数据从上行接口A1发送到汇聚节点G；汇聚节点G将ARP应答发送给网管服务器C。由此，也可以进行网管通路的建立。In one example, when the aggregation node forwards the request to a non-target switch, for example, the network management server accesses a switch in the cross-device link aggregation switch system, and broadcasts the request message to the aggregation node; the aggregation node passes the load Balanced operation, send this message to the switch in the cross-device link aggregation switch system; A link is forwarded to the target switch that needs to respond; the target switch processes the request message in the CPU, and at the same time the broadcast isolation function takes effect, the request message is no longer forwarded, and the MAC address of the request message is not learned; The MAC address of the request message is written into the uplink port, and the network management server responds, and the response data is sent from the uplink interface to the aggregation node; the aggregation node sends the response to the network management server. In another example, specifically, the network management server C needs to manage the switch A, and the network management server C broadcasts the ARP request message to the aggregation node G; the aggregation node G load-balances the ARP request to the switch B through a load balancing operation; Switch B sends the ARP to the CPU of switch B for processing. The CPU of switch B finds that the ARP is not requested by itself, and sends it to the target switch A that needs to respond through the peer-link link. Switch A sends the ARP to the switch The CPU of A performs processing, and the broadcast isolation function takes effect at the same time, switch A no longer forwards the ARP packet, and does not learn the MAC address of the ARP packet; after the switch A processes the ARP in the CPU, the The MAC address is written into the uplink interface A1, and the network management server C responds with an ARP message, and the response data is sent from the uplink interface A1 to the aggregation node G; the aggregation node G sends the ARP response to the network management server C. In this way, the network management channel can also be established.
