The technical abbreviations involved in this application are explained as follows:
VSM: virtual Switch Matrix, i.e. virtual switching matrix. A virtualization technique, i.e., stacking technique, virtualizes a plurality of Ethernet switch devices into a single network device.
A single board: and each network device in the VSM system is called a member device, and the member devices are divided into two different roles according to different functions. Master Master member equipment and Slave spare member equipment, the Master is responsible for overall VSM system management and service processing, and Slave operates as a backup of the Master. Only one Master member can be in a VSM system, but there can be multiple Slave members.
Cascade port: an interface special for connecting member devices in a VSM environment, wherein each member device can transmit information through a cascade port, a plurality of member ports of each device can be provided, and multiple cascade links between two member devices can be automatically aggregated. The network line with cascade ports connected with each other between the member devices is called a cascade line.
VSM identification: in the VSM, each device is uniquely identified by the VSM ID, and the Master and Slave member roles of the VSM are selected by the VSM ID.
The applicant finds that in the prior art, for example, three network devices VSM1, VSM2 and VSM3 may form a ring-shaped VSM stacking system through a multi-cascade port and cascade line configuration, when each of the VSM1, VSM2 and VSM3 detects that the cascade port is in an up state, each VSM state machine starts to operate, a topo message exchange is performed through the cascade port, and each member role, master and Slave is selected according to the VSM id in the topo. And thus into the steady state of the VSM.
The method has the advantages that the topo collection among the VSM member devices is triggered to send a topo collection message under the condition that whether the self cascade ports are up or not, and under the condition that the device single board model and software version are ensured to be correctly networked, the topo collection among the member devices, role election and further stable VSM system stability state are achieved easily, and the following problems are caused.
Problem 1: the core of the stacking technology is to add a stacking head to a message passing through a cascading port for distinguishing the stacking message from a common message, so that the stacking message can pass through the cascading port, and when the types of cascading single boards used by VSM1, VSM2 and VSM3 are inconsistent, under the condition of forced cascading, the types of cascading single boards are inconsistent, topo collecting messages sent by opposite ends can not be identified mutually, and a VSM system can not be established. Similarly, the hardware difference is removed, the software version is also updated continuously and iteratively, if the software versions of the member devices are inconsistent, the problem of uncertainty caused by inconsistent processing of each member device when the member devices process the same event is also caused, and the system is unstable.
The two devices VSM1 are configured with a stacking technology and are connected with a common Ethernet port of another common SW network device which is not configured with the stacking technology through a cascade port cascade line, so that the VSM1 cannot confirm whether the devices connected with the VSM1 have a stacking function or not, but the cascade port is in an up state, and thus a topo message is continuously sent for stacking attempt. Under such a wrong networking environment, the operation of the VSM1 is always in an unstable state, and if a user uses the network environment without knowledge, the situation of network oscillation easily occurs, and the problem of inquiry is inconvenient.
Aiming at the problems existing in the prior art, the application provides a method for constructing a virtual switching matrix, which aims at checking the uniformity of the single board types and the software versions of the member equipment of a stacking system before starting a VSM state machine to collect topos, carrying out log record on the illegal detection condition, reminding a user, and periodically detecting whether the opposite single board types and the software versions are consistent or not.
The following describes the content of the present application in detail with the aid of specific examples.

As shown in fig. 1, the system architecture 10 may include network devices 101, 102, 103, a network 104. The network 104 is the medium used to provide communication links between the network devices 101, 102, 103. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
The network device 101 may send a probe request message to a remote device (which may be, for example, the network devices 102, 103) when detecting that an up port exists in its own tandem port; the network device 101 may receive a reply message from the remote device (which may be the network device 102, 103, for example) in a preset time; the network device 101 may determine device information of the remote device (which may be, for example, the network devices 102, 103) according to the reply message; the network device 101 and the remote device (which may be, for example, the network devices 102, 103) may perform the construction of a virtual switching matrix, for example, when the device information satisfies a preset policy; after successful construction, the virtual switching matrix (which may, for example, comprise network devices 101, 102, 103) performs task processing.
It should be noted that, the method for constructing a virtual switching matrix provided in the embodiments of the present application may be executed by the network devices 101, 102, 103, and accordingly, the apparatus for constructing a virtual switching matrix may be disposed in the network devices 101, 102, 103.

As shown in fig. 2, in S202, when detecting that the up port exists in the own cascade port, the network device sends a probe request message to the remote device. The network device may, for example, turn on the virtual switch matrix building function; detecting a self cascade interface; and when the up port exists in the self cascade port, sending a detection request message to the remote equipment.
In S204, a response message of the probe request message from the remote device is received within a preset time. The remote device may, for example, generate the response message through device information after receiving the probe request message; and the remote equipment generates and transmits a detection request message.
In a specific application, after the detection message is sent out, a waiting response timer is started. If the remote device does not turn on the VSM stacking function, or interfaces with a common port, or other vendor devices that do not support probing, the remote device will not respond to the probe request.
In one embodiment, the port sends the probe request information by adopting periodic timing, default time is 3s, the probe period can be configured by configuring a control plane, the minimum probe time can be, for example, 3s, the time is not suitable to be configured too large, the waiting timeout time is too long when the time is too large, the response alarm effect is influenced, too small probe is not suitable to be too frequent, the response timeout time is too short, and the probe precision is influenced.
In practical cases, the user may be configured according to the distance between the actual VSM topologies and the size of the service, which is not limited in this application.
In S206, device information of the remote device is determined according to the response message. And determining whether all the sent detection request messages receive response messages.
In one embodiment, after all the probe request messages receive the response message, the device information of the remote device is extracted according to the response message. More specifically, if the remote device opens the VSM stacking function and the port to be connected is a cascade port, the remote device packages and sends its own board information and software version information to the detector when detecting the message, and the remote device itself also sends the remote detection message to other devices
In one embodiment, after not receiving the response messages of all the probe request messages, obtaining the remote device information of the response messages which are not received; and generating an abnormal record according to the equipment information. More specifically, after the timer times out, if the up cascade port still exists and does not acquire the response, the networking environment is considered to be abnormal. At the moment, the system log is recorded by detecting abnormal information of the up cascade port without response, and the user is prompted to check the networking environment.
In S208, when the device information satisfies a preset policy, the network device and the remote device perform virtual switch matrix construction. For example, the device information of the network device and the device information of the remote device may be compared; and when the comparison results are consistent, the network equipment and the remote equipment are used for constructing a virtual switching matrix.
More specifically, the detected remote single board information and software version are compared with the single board information and software version of the local device respectively, when the obtained remote single board information and software version of the remote device have remote information inconsistent with the local single board information or the software version, the inconsistent remote single board information, the software version information and the corresponding cascading port information of the received response message are recorded into a system log, and a user is prompted to check the networking environment.
More specifically, the network device and the remote device trigger state machines of a virtual switching matrix; the state machine performs topo collection for virtual switching matrix construction.
In S210, after the construction is successful, the virtual switch matrix performs task processing. If the comparison result shows that all the remote single board information and the software version information are consistent with the local equipment, triggering the VSM stacking state machine to collect topo and performing corresponding network construction actions to complete the construction of the virtual switching matrix.
According to the method for constructing the virtual switching matrix, when detecting that an up port exists in a cascade port of the network equipment, a detection request message is sent to a remote device; receiving a response message of the detection request message from the remote equipment within a preset time; determining the equipment information of the remote equipment according to the response message; when the equipment information meets a preset strategy, the network equipment and the remote equipment are used for constructing a virtual switching matrix; after the virtual switching matrix is successfully built, the virtual switching matrix is subjected to task processing, so that the error probability of the virtual switching matrix network environment can be reduced, the safety and stability of a network are ensured, and the working efficiency of network operation and maintenance investigation for solving the network problem is improved.
