Description

Technical Field

[0001] The present application relates to the field of network communication technology, and in particular to an automated testing method, device and equipment for detecting VRRP traffic switching. Background Art

[0002] In the existing VRRP (Virtual Routing Redundancy Protocol) technology, at least two devices (such as routers or switches) are usually required to implement the redundant backup function. These devices form a virtual router, and by configuring a virtual IP address as the default gateway, redundant management of network traffic is implemented. Under normal circumstances, one device acts as the Master to handle all traffic, while the other device is on standby as the Backup.

[0003] In order to verify whether the redundancy function of VRRP is working properly, it is usually necessary to artificially create a fault to trigger the master-slave switch. For example, you can shut down the interface of the master device or simulate a link failure to observe whether the backup device can correctly take over the traffic. In actual testing, technicians will manually shut down the uplink interface of the master device, or configure the interface tracking function to lower the priority of the master device, thereby triggering the preemption of the backup device. In addition, you can also verify whether the traffic has been correctly forwarded to the new Master device by testing the network access of the terminal device. Although this test method can effectively verify the redundancy function of VRRP, it has some limitations. For example, artificially creating faults may have a certain impact on the normal operation of the network, and the testing process is relatively cumbersome.

[0004] Therefore, how to achieve rapid fault detection and switching, thereby improving the efficiency of detecting VRRP traffic switching, is a problem that needs to be solved urgently.

[0070] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0071] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0072] The main solution of the embodiment of the present application is: an automated test method for detecting VRRP traffic switching, the automated test method for detecting VRRP traffic switching is applied to an automated test terminal in an automated test system for detecting VRRP traffic switching, the automated test system for detecting VRRP traffic switching comprises a plurality of switches and the automated test terminal, the plurality of switches comprises a first switch, a second switch, a third switch and a fourth switch, wherein the output ends of the first switch and the second switch are respectively connected to the input end of the third switch, the output end of the third switch is connected to the automated test terminal, and the input ends of the first switch and the second switch are respectively connected to the output end of the fourth switch;

[0073] The automated test terminal, the first switch, the second switch, the third switch and the fourth switch are all provided with a plurality of virtual gateways, and are connected through the virtual gateways corresponding to the respective switches. The first switch and the second switch are respectively provided with priorities, and the fourth switch is also provided with a simulated external network address. The method described includes: according to a preset routing configuration rule, opening up the three-layer routing settings of the automated test terminal, the first switch, the second switch, the third switch and the fourth switch; configuring the first switch and the second switch to be mutually active and standby according to the VRRP protocol; performing link detection on the interfaces connected to the first switch, the second switch and the third switch to obtain a first link detection result; performing link detection on the interfaces connected to the first switch, the second switch and the fourth switch to obtain a second link detection result.

[0074] In this embodiment, for the convenience of description, the following description is made by taking the identification automation computer as the execution subject.

[0075] In the prior art, it is usually necessary to artificially create a fault to trigger the master-slave switch. For example, the interface of the master device can be shut down or a link failure can be simulated to observe whether the backup device can correctly take over the traffic. In actual testing, the technician will manually shut down the uplink interface of the master device, or configure the interface tracking function to lower the priority of the master device, thereby triggering the preemption of the backup device. In addition, the network access of the terminal device can be tested to verify whether the traffic has been correctly forwarded to the new Master device. Although this test method can effectively verify the redundancy function of VRRP, it has some limitations. Artificially created faults may have a certain impact on the normal operation of the network, and the test process is relatively cumbersome.

[0076] The present application provides a solution that simplifies the common VRRP two-computer test into a single-computer test, and uses an automated method to perform traffic switching tests, thereby avoiding some of the impacts that artificial faults may have on the normal operation of the network, achieving rapid fault detection and switching, and thus improving the efficiency of detecting VRRP traffic switching.

[0077] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes a computer as an example to illustrate this embodiment and the following embodiments.

[0078] Based on this, the embodiment of the present application provides an automated testing method for detecting VRRP traffic switching, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the automated testing method for detecting VRRP traffic switching in the present application.

[0079] In this embodiment, the automated testing method for detecting VRRP traffic switching includes steps S10 to S40:

[0080] Step S10, according to the preset routing configuration rules, the three-layer routing settings of the automated test terminal, the first switch, the second switch, the third switch and the fourth switch are connected;

[0081] It should be noted that the preset routing configuration rules can be the rules used in network devices (such as routers or three-layer switches) to guide data packet forwarding, and the three-layer routing settings can refer to configuring the routing function on a three-layer network device (such as a three-layer switch or router) to achieve communication between different networks (such as VLANs, subnets or external networks).

[0082] It can be understood that by configuring the IP address of the switch according to the preset routing rules, a default path or a specific path for network traffic is specified, thereby ensuring that the data packet can correctly reach the destination.

[0083] In a feasible implementation, step S10 may include: setting the interfaces connected to each switch to trunk mode; releasing all virtual subnets, and configuring a static route for the fourth switch to receive all traffic with unknown destination addresses; in the first virtual subnet, allocating IP addresses to the first switch, the second switch, the third switch, the fourth switch and the automated test terminal; in the second virtual subnet, allocating IP addresses to the first switch, the second switch, the third switch and the automated test terminal; in the third virtual subnet, allocating IP addresses to the first switch, the second switch, the fourth switch and the automated test terminal; in the fourth virtual subnet, allocating IP addresses to the first switch and the fourth switch; in the fifth virtual subnet, allocating IP addresses to the second switch and the fourth switch.

[0084] For example, the automation computer connects to the switch command line through the paramiko module, and the interface connected to the switch is configured in trunk mode, allowing vlan1-10 (all virtual subnets) to pass. The configuration is as follows Figure 2 As shown in the three-layer interface IP address, sw1 (the first switch) and sw2 (the second switch) are each configured with a static route to the simulated external network, and sw4 (the fourth switch) is also configured with a 0.0.0.0 static route pointing to all returns, opening up all three-layer routing settings, in the first virtual subnet corresponding to vlanif1, IP addresses are allocated to sw1, sw2, sw3 (the third switch), sw4 and the automation computer (automatic test terminal); in the second virtual subnet corresponding to vlanif2 and vlan2, IP addresses are allocated to sw1, sw2, sw3 and the automation computer; in the third virtual subnet corresponding to vlanif3 and vlan3, IP addresses are allocated to sw1, sw2, sw4 and the automation computer; in the fourth virtual subnet corresponding to vlanif4, IP addresses are allocated to sw1 and sw4; in the fifth virtual subnet corresponding to vlanif5, IP addresses are allocated to sw2 and sw4.

[0085] The above is only a feasible implementation of step S10 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S10.

[0086] Step S20, configuring the first switch and the second switch to be mutually active and standby according to the VRRP protocol;

[0087] It should be noted that the VRRP (Virtual Router Redundancy Protocol) protocol combines multiple routing devices into a virtual router. VRRP can ensure that when the main device fails, the backup device can automatically take over the work, thereby ensuring the continuity and reliability of network communications. The main and backup refer to routing devices that are in the main and backup states.

[0088] It can be understood that by configuring the first switch and the second switch to serve as a primary and a backup for each other, bandwidth can be saved, ensuring that the network can be seamlessly switched when a device fails, thereby ensuring the continuity and stability of the network.

[0089] In a feasible implementation, step S20 may include: in the second virtual subnet, setting the first switch as the main switch and the second switch as the backup switch; in the third virtual subnet, setting the second switch as the main switch and the first switch as the backup switch.

[0090] For example, in the second virtual subnet corresponding to vlanif2, 2, the virtual gateway of the vrrp interface of sw1 and sw2 is configured to be 192.168.2.254, with a priority of 120, and the virtual gateway of the interface vrrp of vlanif3 is configured to be 192.168.3.254, with a priority of 120. The default priority is 100. The larger the priority, the higher the priority. In vlanif2, sw1 is the main device and sw2 is the backup device. In vlanif3, sw2 is the main device and sw1 is the backup device. sw1 and sw2 are mutually main and backup devices, and no bandwidth is wasted.

[0091] The above is only a feasible implementation of step S20 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S20.

[0092] Step S30, performing link detection on interfaces connected to the first switch, the second switch, and the third switch to obtain a first link detection result;

[0093] It should be noted that the link detection can be performed by sending a signal to the simulated external network address through the automated test terminal to confirm whether normal communication is possible, and the first link detection result can be a communication result, including two situations: normal communication and abnormal communication.

[0094] It can be understood that by disconnecting the link and creating a link failure to automatically trigger the active-standby switching of VRRP, if the switching is successful, normal communication can be achieved. If the switching fails, normal communication cannot be achieved. The communication results can be recorded for subsequent troubleshooting to ensure that the network can switch normally when an actual failure occurs, avoiding business interruption, effectively verifying the correctness of the VRRP configuration, and providing an important basis for subsequent network optimization and troubleshooting.

[0095] In a feasible implementation, step S30 may include: setting the interface of the third switch connected to the automated test terminal to access mode; modifying the IP address of the automated test terminal to the second VLAN address, and setting the address of the virtual gateway to the second VLAN virtual address; sending a signal to the simulated external network address to detect whether communication is possible; in normal communication, disconnecting the first link between the first switch and the third switch; sending a signal to the simulated external network address to detect whether communication is possible; in normal communication, checking the role of the second switch; restoring the first link, modifying the IP address of the automated test terminal to the third VLAN address, and setting the address of the virtual gateway to the third VLAN virtual address; sending a signal to the simulated external network address to detect whether communication is possible; in normal communication, disconnecting the second link between the second switch and the third switch; sending a signal to the simulated external network address to detect whether communication is possible; in normal communication, checking the role of the first switch.

[0096] For example, Figure 2 As shown, configure the interface connected to the automation computer in sw3 to access mode and release vlan2. You can use the subprocess module in Python to change the automation computer IP address to Figure 2 The vlan2 address is 192.168.2.50 (the second vlan address), the gateway is set to the vlan2 virtual address 192.168.2.254 (the second vlan virtual address), and the subprocess module is used to call the cmd (command line) to ping Figure 2 In the simulation, the L0 address of the external network is used. When they can communicate with each other, the link (the first link) between sw1 and sw3 is shut down through the command line.

[0097] ping Figure 2 In the simulation, if the L0 address of the external network can communicate with each other, use the vrrp command to check whether the status of device sw2 becomes the master device;

[0098] Log in to the sw3 device to restore the first link, and modify the interface connected to the automation computer to vlan3, and continue to modify the ip address of the automation computer to the vlan3 address 192.168.3.50 (the third vlan address) in the figure, and set the gateway to the vlan3 virtual address 192.168.3.254 (the third vlan virtual address);

[0099] ping Figure 2 Simulate the L0 address of the external network. If they can communicate with each other, then disconnect the link (the second link) between sw1 and sw2 through the command line shutdown;

[0100] ping Figure 2 Simulate the L0 address of the external network. If they can communicate with each other, use the vrrp command to check whether the backup device sw1 becomes the master device.

[0101] The above is only a feasible implementation of step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S30.

[0102] Step S40: performing link detection on interfaces connected to the first switch, the second switch, and the fourth switch to obtain a second link detection result.

[0103] It should be noted that the link detection can be performed by sending a signal from the automated test terminal to the simulated external network address to confirm whether normal communication is possible. The second link detection result can be the communication result of the automated test terminal sending a signal to the simulated external network address, including both normal communication and non-normal communication.

[0104] It can be understood that this step tests the interfaces connecting the first switch, the second switch and the fourth switch. When the uplink fails, VRRP will detect and reduce the priority of the interface of the corresponding virtual gateway, so that the backup device becomes the main device to participate in forwarding.

[0105] In a feasible implementation, step S40 may include: starting uplink detection of the first switch and the second switch; setting the interface connecting the first switch and the fourth switch, and the interface connecting the second switch and the fourth switch as uplink detection ports; disconnecting the third link between the first switch and the fourth switch; sending a signal to the simulated external network address to detect whether they can communicate with each other; in normal communication, determining that the master-slave preemption mechanism is in effect; restoring the third link, modifying the IP address of the automated test terminal to the third VLAN address, setting the virtual gateway address to the third VLAN virtual address, and disconnecting the fourth link between the second switch and the fourth switch; sending a signal to the simulated external network address to detect whether they can communicate with each other; in normal communication, determining that the master-slave preemption mechanism is in effect.

[0106] For example, Figure 2 As shown, configure the uplink detection of sw1, sw2 and sw4 of VRRP, and enable the priority preemption mechanism. When the uplink of sw1, sw2 and sw4 fails, the priority of the link is reduced to trigger the active-standby switchover mechanism. Enable the uplink detection of sw1 and sw2, set the port connected to sw1, sw2 and sw4 as the uplink detection port, and shut down the interface connected to sw1 and sw4. Ping Figure 2 If the L0 address of the simulated external network cannot be pinged, it means that the master-slave preemption mechanism is not effective. If they can communicate with each other, after the third link is restored, modify the connection between sw3 and the automation computer to Figure 2 In vlan3, change the address of the automation computer to the same network segment address of vlanif3, set the gateway to the vlan3 virtual address, shut down the interface connected to sw2 and sw4, and ping Figure 2 If the L0 address of the simulated external network cannot be pinged but can be pinged successfully, it means that the master-slave preemption mechanism is not effective.

[0107] The above is only a feasible implementation of step S40 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S10.
