Background
The current popular network management method of the cross-device link aggregation switch is as follows: two switches, an upstream aggregation node and a network management server of the cross-device link aggregation switch system are respectively configured with a three-layer network which is independently used by a network management.

And because a three-layer network specially used for network management needs to be configured, additional IP addresses and vlan ids are consumed; the maintenance complexity is increased, and besides the service network maintenance, a network of network management needs to be maintained on the equipment.

The invention relates to a network management method for cross-device link aggregation, which is applied to switches in a cross-device link aggregation switch system. The specific process is shown in FIG. 1.
In this embodiment, the sub-IPs of the switches in the current cross-device link aggregation switch system and the first exchange link between the switches are used for information interaction, so that the network management server can directly perform network management on each switch device of the cross-device link aggregation switch system without adding additional configuration, thereby improving the convenience of network management, improving the usability of the network, and saving the network configuration cost.
The following describes implementation details of the network management method for cross-device link aggregation according to this embodiment in detail, and the following description is only provided for facilitating understanding of the implementation details and is not necessary to implement this solution.
In step 101, a request for operating the switch, which is sent by the network management server through the sink node, is received, and the request carries a sub-IP address of a target switch corresponding to the operation.
Generally, when a network management server accesses a network including a cross-device link aggregation switch system, the accessed location is at a sink node side, and the cross-device link aggregation switch system is viewed from the sink node side, forwarding of a data request is load-shared, and when the network management server manages the network of the cross-device link aggregation switch system, if a certain switch is managed, the data request may be load-shared at the sink node, that is, after calculation processing of the sink node, the data request is not necessarily sent to a target switch, so that a problem of broken link of the network management occurs. In this embodiment, a switch in the cross-device link aggregation switch system not only shows the external IP address of the system to an external device, but also shows the sub-IP addresses of the switches, so as to clarify the requested target switch. On this basis, the network management server will carry the sub-IP address of the target switch in the request sent by the sink node, so as to clarify the target switch of the request.
In step 102, judging whether the target switch is the current switch or not according to the sub-IP address of the current switch; and 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, forwarding the request to the another switch through a first link, wherein the first link is a communication link between the current switch and the another switch.
After receiving the request from the aggregation node, the switch judges whether the current switch is the requested target switch or not according to the sub-IP address of the current switch receiving 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 indicates that the current switch receiving the request is the target switch of the request, and the request is processed or responded correspondingly. In one example, when the current switch receives the request and a Central Processing Unit (CPU) of the current switch determines that the current switch is the target switch, the current switch obtains a source MAC address of the request from the request, processes or responds to the request, and returns to the source MAC address of the request.
In one example, the first link may be a peer-link between the current switch and another switch (the target switch). And a communication link is not required to be newly established, and a corresponding subsequent maintenance process is not required to be newly added.
In one 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 updating the correspondence between the MAC address of the request and the transmission port, which may be defined as not learning the MAC address in some examples. The MAC address in the request is a target address of the switch responding to the request, and the corresponding relation between the MAC address of the request and the transmission port is prohibited from being updated, so that the corresponding relation between the MAC address in the request and the transmission port cannot be updated or covered for multiple times, namely, the target switch still keeps the corresponding relation between the MAC address and the uplink interface after the first link is forwarded once, thereby avoiding the MAC drift phenomenon and maintaining the normal use of the MAC address table entry. If the MAC drift phenomenon occurs, that is, because the transmission port corresponding to the MAC address is updated, the target switch stores the corresponding relationship between the MAC address and the first link port, and after receiving a request sent to the target switch by the sink node next time, the target switch performs reply or processing according to the corresponding relationship between the MAC address and the first link port, and after the processing, the original corresponding relationship is covered by the corresponding relationship between the MAC address and the uplink interface, and a transmission path is disordered due to repeated times, which prevents the information reply response in the system. In this example, since the correspondence between the MAC address and the transmission port in the update prohibition request ensures that the destination address of the response information is correct and the transmission path is stable, and the transmission path is not confused due to MAC address drift, thereby ensuring that the information transmission path in the cross-device link aggregation device is normal.
In one 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 inhibits the request from being retransmitted, or in some examples may be defined as each switch having broadcast suppression. That is, the same data is allowed to be transmitted only once by the switch device, and when the received request is transmitted by the switch, retransmission is not allowed. The method avoids the request from returning to the switch for forwarding the request, avoids the request from returning to the sink node and also avoids the request from being transmitted to the downstream equipment, reduces unnecessary transmission resources and processing resource waste, and improves the data processing quality and speed of the cross-equipment link aggregation switch system.
In another example, the network management method for cross-device link aggregation further includes: if the current switch receives a request from the first link, the current switch transmits a response message of the request to the sink node from an uplink interface of the current switch; and the uplink interface is an interface for information interaction between the current switch and the sink node. That is, if the request received by the current switch is directly sent by the sink node, a response reply is performed on the uplink interface of the current switch; and if the request of the current switch is forwarded from other switches, responding and replying at the uplink interface of the current switch. And a reply path of the response message is regulated, so that the response message can respond to the request in the shortest distance, namely, the response message is directly sent to the sink node through the uplink interface of the switch, the response time is reduced, and the data processing rate of the cross-equipment link aggregation switch system is improved.
In addition, the first link may be a peer-link, and the request may include an Address Resolution Protocol (ARP) request.
In an implementation process, when an ARP request is sent from a network management server to access a certain switch in a cross-device link aggregation switch system, if the load of the ARP request is balanced by a sink node to another switch in the cross-device link aggregation, the ARP request is discarded because a correct response cannot be obtained, so that the ARP of the network management server cannot be correctly responded. By adopting the embodiment, the ARP request message is released on the port of the peer-link through access control or other methods, so that the ARP message can reach the target side through the peer-link no matter which side of the cross-equipment link aggregation switch system the ARP message is loaded and balanced to the switch; and the switch is identified and judged through the sub-IP address of the switch existing in the original network, a new network architecture is not required to be added, and the resource occupation and the later maintenance requirement are reduced. Meanwhile, the ARP message can not be looped back to the sink node through broadcast inhibition. In order to prevent MAC drift between the uplink interface of the switch and the aggregation node and the port of the peer-link, the port of the peer-link keeps the MAC address in an unlearned state. In addition, after the CPU of the target switch receives the ARP packet, an ARP reply is performed from the upstream interface of the switch regardless of whether the ARP packet is received from the upstream interface of the switch or from the port of the peer-link.
By the method of the embodiment, the network management server can correctly forward the ARP request sent by a certain switch of the cross-device link aggregation switch system to the switch device to be responded no matter which side the aggregation node sends to, and any table entry and forwarding behavior which have abnormal interference to the cross-device link aggregation switch system can not occur in the whole process. Under the condition that extra configuration is not needed, the network management is directly carried out on each switch device of the cross-device link aggregation switch system, the convenience degree of the network management is improved, the usability of the network is improved, and the network configuration cost is saved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are within the scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
One embodiment of the invention relates to a network management system for cross-device link aggregation. As shown in fig. 2, includes:
the system comprises a network management server, a sink node in communication connection with the network management server and a cross-device link aggregation switch system in communication connection with the sink node, wherein the cross-device link aggregation switch system comprises at least two switches, and each switch is respectively provided with a sub-IP address of an IP of the cross-device link aggregation switch system;
the network management server 201 is configured to send a request for operating the switch to the switch in the cross-device link switch system through the sink node, where the request includes a sub-IP address of an operating target switch;
the aggregation node 202 is configured to forward the request to a switch in the cross-device link aggregation switch system;
the switch 203 is configured to receive a request sent by the network management server through the aggregation node, and forward the request to another switch through a first link 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, where the first link is a communication link between the current switch and the another switch.
In one example, the switch 203 is also configured to transmit to the aggregation node 202 over the upstream interface in response to the request.
In one example, when the sink node forwards the request to the target switch, for example, the network management server accesses a certain switch of the cross-device link aggregation switch system, and broadcasts and sends the request message to the sink node; the sink node directly sends the message to a correct switch needing to respond through load balancing operation; the exchanger needing to respond processes the request message in the CPU, learns the MAC address of the network management server at the uplink interface connected with the sink node, responds to the request message, sends the response information to the sink node from the uplink interface, and sends the response to the network management server by the sink node. In another example, specifically, the network management server C needs to manage the switch a, and the network management server sends an ARP request message to the aggregation node G in a broadcast manner; the sink node G sends the ARP request to the switch A in a load balancing way through load balancing operation; the switch A receives the ARP message from the port A1, sends the ARP message to a CPU of the switch A for processing, the port A1 learns the MAC address of the network management server C, and responds to the ARP of the network management server, and the response data is sent to a sink node G from the port A1; and the sink node G sends the ARP response to the network management server C. Thereby, a network management path can be established.
In one example, when the sink node forwards the request to a non-target switch, for example, the webmaster server accesses a certain switch of the cross-device link aggregation switch system, and broadcasts the request message to the sink node; the sink node sends the message to a switch of a non-target switch in the cross-device link aggregation switch system through load balancing operation; the switch processes the request message in the CPU, and the CPU forwards the request message to a target switch needing to respond through a first link if finding that the request message does not request the switch; the target switch processes the request message in the CPU, and simultaneously, the broadcast isolation function takes effect, the request message is not forwarded any more, and the MAC address of the request message is not learned; writing the MAC address of the request message into an uplink port, responding to the network management server, and sending the response data to the sink node from the uplink port; the sink 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 and sends the ARP request message to the sink node G; the sink node G sends the ARP request to the switch B in a load balancing way through load balancing operation; the switch B sends the ARP to the CPU of the switch B for processing, the CPU of the switch B finds that the ARP does not request the CPU of the switch B, the ARP is sent to a target switch A needing to respond through a peer-link, the switch A sends the ARP to the CPU of the switch A for processing, meanwhile, the broadcast isolation function takes effect, the switch A does not forward the ARP message any more, and does not learn the MAC address of the ARP message; after the switch A processes the ARP in the CPU, the MAC address of the ARP message is written into an uplink interface A1, the response of the ARP message is carried out on a network management server C, and the response data is sent to a sink node G from the uplink interface A1; and the sink node G sends the ARP response to the network management server C. Therefore, the network management path can be established.
Compared with the network management system of a common cross-device link aggregation switch system, the technical means can ensure that the network management server can correctly access any switch of the cross-device link aggregation switch system without newly establishing any network management network through the processing of the technical means, and the forwarding strategy of the aggregation node and the forwarding behavior and strategy of the whole cross-device link aggregation switch system can not be changed. The method greatly simplifies the network management network configuration of the cross-device link aggregation switch system, can directly carry out network management by means of a service network, saves IP addresses and vlan resources because of no need of increasing network configuration, improves the stability and reliability of network maintenance and reduces the network maintenance cost.

In addition, if the current switch receives the request from the first link, the current switch prohibits updating the corresponding relationship between the MAC address of the request and the transmission port.
In addition, if the current switch receives a request from the first link, the current switch prohibits the request from being retransmitted.
In addition, if the current switch receives the request from the first link, the current switch transmits a response message of the request to the sink node from the uplink interface of the current switch; and the uplink interface is an interface for information interaction between the current switch and the sink node.
