Description

Technical Field

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

[0002] In existing VRRP (Virtual Router Redundancy Protocol) technology, at least two devices (such as routers or switches) are typically required to achieve redundancy backup. These devices form a virtual router, which uses a virtual IP address as the default gateway to achieve redundant management of network traffic. Under normal circumstances, one device acts as the Master, handling all traffic, while the other device remains in standby mode as the Backup.

[0003] To verify the proper functioning of VRRP's redundancy, it's typically necessary to artificially create faults to trigger master-slave failover. For example, this can be done by shutting down the master device's interface or simulating a link failure, observing whether the backup device can correctly take over traffic. In actual testing, technicians manually disable the master device's uplink interface or configure interface tracing to lower the master device's priority, thus triggering preemption by the backup device. Additionally, testing the network access of terminal devices can verify whether traffic is correctly forwarded to the new master device. While this testing method effectively verifies VRRP's redundancy, it has some limitations. For instance, artificially creating faults may impact normal network operation, 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 an urgent problem to be solved.

[0070] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0071] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0072] The main solution of this application embodiment is: an automated testing method for detecting VRRP traffic switching. The automated testing method for detecting VRRP traffic switching is applied to an automated testing terminal in an automated testing system for detecting VRRP traffic switching. The automated testing system for detecting VRRP traffic switching includes a plurality of switches and the automated testing terminal. The plurality of switches includes a first switch, a second switch, a third switch, and a fourth switch. The output terminals of the first switch and the second switch are respectively connected to the input terminal of the third switch. The output terminal of the third switch is connected to the automated testing terminal. The input terminals of the first switch and the second switch are respectively connected to the output terminal of the fourth switch.

[0073] The automated test terminal, the first switch, the second switch, the third switch, and the fourth switch are all equipped with multiple virtual gateways, and are interconnected through the virtual gateways corresponding to each switch. The first switch and the second switch are respectively assigned priorities, and the fourth switch is also equipped with a simulated external network address. The method includes: setting up the Layer 3 routing settings of the automated test terminal, the first switch, the second switch, the third switch, and the fourth switch according to preset routing configuration rules; configuring the first switch and the second switch to be mutually primary and backup 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; and 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 ease of description, the following description will use the identification of an automated computer as the execution subject.

[0075] Current technologies typically require artificially created faults to trigger master-slave failover. For example, this can be achieved by disabling the master device's interface or simulating a link failure to observe whether the backup device can correctly take over traffic. In actual testing, technicians manually disable the master device's uplink interface or configure interface tracking to lower the master device's priority, thereby triggering preemption by the backup device. Additionally, testing the network access of terminal devices can verify whether traffic has been correctly forwarded to the new master device. While this testing method effectively verifies VRRP's redundancy function, it has limitations: artificially created faults may affect normal network operation, and the testing process is relatively cumbersome.

[0076] This application provides a solution that simplifies the common two-computer VRRP test to a single computer test, and uses an automated method to perform traffic switching tests. This avoids the impact that manual fault-causing may have on the normal operation of the network, and enables rapid fault detection and switching, thereby improving the efficiency of detecting VRRP traffic switching.

[0077] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions. The following description uses a computer as an example to illustrate this embodiment and the subsequent embodiments.

[0078] Based on this, embodiments of this application provide an automated testing method for detecting VRRP traffic switching, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the automated testing method for detecting VRRP traffic switching in this 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, enable the Layer 3 routing settings of the automated test terminal, the first switch, the second switch, the third switch and the fourth switch;

[0081] It should be noted that the preset routing configuration rules can be the rules used in network devices (such as routers or Layer 3 switches) to guide the forwarding of data packets. Layer 3 routing settings can refer to configuring routing functions on Layer 3 network devices (such as Layer 3 switches or routers) to enable communication between different networks (such as VLANs, subnets, or external networks).

[0082] Understandably, by configuring the switch's IP address according to preset routing rules, the default or specific path of network traffic can be specified, thereby ensuring that data packets can correctly reach their destination.

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

[0084] For example, the automation computer connects to the switch command line via the paramiko module. The interface connected to the switch is configured in trunk mode, allowing VLANs 1-10 (all virtual subnets), and configured as follows. Figure 2 The three Layer 3 interface IP addresses are configured as follows: SW1 (first switch) and SW2 (second switch) each have a static route to the simulated external network; SW4 (fourth switch) also has a 0.0.0.0 static route pointing to all return routes. All Layer 3 routing settings are enabled. Within the first virtual subnet corresponding to VLANIF1, IP addresses are assigned to SW1, SW2, SW3 (third switch), SW4, and the automated computer (automated test terminal); within VLANIF2 and the second virtual subnet corresponding to VLAN2, IP addresses are assigned to SW1, SW2, SW3, and the automated computer; within VLANIF3 and the third virtual subnet corresponding to VLAN3, IP addresses are assigned to SW1, SW2, SW4, and the automated computer; within the fourth virtual subnet corresponding to VLANIF4, IP addresses are assigned to SW1 and SW4; and within the fifth virtual subnet corresponding to VLANIF5, IP addresses are assigned to SW2 and SW4.

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

[0086] Step S20: Configure the first switch and the second switch to be primary and backup to each other 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 primary device fails, the backup device can automatically take over the work, thereby ensuring the continuity and reliability of network communication. The primary and backup refer to the routing devices in the status of primary and backup devices.

[0088] Understandably, configuring the first and second switches to act as primary and backup switches can save bandwidth, ensure seamless switching in the event of device failure, and guarantee network continuity and stability.

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

[0090] For example, within the second virtual subnet corresponding to vlanif2, 2, configure the VRRP virtual gateway of the vlanif2 interface in sw1 and sw2 as 192.168.2.254 with a priority of 120, and configure the VRRP virtual gateway of the interface in vlanif3 as 192.168.3.254 with a priority of 120. The default priority is 100. The higher the priority, the more likely it is to be the primary device. In vlanif2, sw1 is the primary device and sw2 is the backup device. In vlanif3, sw2 is the primary device and sw1 is the backup device. sw1 and sw2 are mutually primary and backup, without wasting bandwidth.

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

[0092] Step S30: Perform link detection on the interfaces connecting the first switch, the second switch, and the third switch to obtain the first link detection result;

[0093] It should be noted that link detection can be performed by sending signals to a simulated external network address through an automated testing terminal to confirm whether normal communication is possible. The first link detection result can be the communication result, including both normal communication and non-normal communication.

[0094] Understandably, disconnecting the link creates a link failure to automatically trigger VRRP primary / backup switching. If the switch is successful, normal communication is possible; if the switch fails, normal communication is impossible. The communication results can be recorded for subsequent troubleshooting. This ensures that the network can switch normally when a real fault occurs, avoiding service interruption, effectively verifying the correctness of the VRRP configuration, and providing important evidence for subsequent network optimization and troubleshooting.

[0095] In one feasible implementation, step S30 may include: setting the interface of the third switch connecting 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; during 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; during 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; during 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 mutual communication is possible; during normal communication, checking the role of the first switch.

[0096] For example, such as Figure 2 As shown, the interface connecting the automation computer in SW3 is configured to access mode, allowing VLAN 2. The automation computer's IP address can be changed using the subprocess module in Python. Figure 2 The VLAN 2 address is set to 192.168.2.50 (the second VLAN address), and the gateway is set to the VLAN 2 virtual address 192.168.2.254 (the second VLAN virtual address). Then, the subprocess module is used to call cmd (command line) to ping the VLAN. Figure 2 The L0 address of the simulated external network is disconnected when communication between sw1 and sw3 is possible via command line shutdown (the first link).

[0097] ping Figure 2 If the L0 address of the simulated external network can communicate with each other, use the VRRP command to check whether the status of device sw2 has become the master device;

[0098] Log in to the sw3 device to restore the first link, and change the interface connected to the automation computer to VLAN 3. Then, change the IP address of the automation computer to the VLAN 3 address 192.168.3.50 (third VLAN address) shown in the figure, and set the gateway to the VLAN 3 virtual address 192.168.3.254 (third VLAN virtual address).

[0099] ping Figure 2 If the L0 address of the simulated external network can communicate with each other, then disconnect the link (second link) connecting sw1 and sw2 by shutting down the command line.

[0100] ping Figure 2 If the L0 address of the simulated external network can communicate with each other, use the VRRP command to check whether the backup device sw1 has become the master device.

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

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

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

[0104] Understandably, this step tests the interfaces connecting the first switch, the second switch, and the fourth switch. When the uplink fails, VRRP will detect this and lower the priority of the corresponding virtual gateway interface, making the backup device the primary device to participate in forwarding.

[0105] In one feasible implementation, step S40 may include: enabling uplink detection for the first switch and the second switch; setting the interfaces connecting the first switch and the fourth switch, and the interfaces 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; if normal communication is achieved, determining that the primary / backup 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; if normal communication is achieved, determining that the primary / backup preemption mechanism is in effect.

[0106] For example, such as Figure 2 As shown, configure uplink detection for VRRP SW1, SW2, and SW4, and enable a priority preemption mechanism. When the uplink of SW1, SW2, or SW4 fails, the priority of that link is reduced, triggering a master-slave switchover mechanism. Enable uplink detection for SW1 and SW2, set the port connecting SW1, SW2, and SW4 as the uplink detection port, and shut down the interface connecting SW1 and SW4. Ping the port. Figure 2 If the L0 address of the simulated external network cannot be pinged, it indicates that the primary / backup preemption mechanism is not working. If communication is possible, after the third link is restored, modify the connection between SW3 and the automation computer. Figure 2 In the configuration, change the address of the automation computer to the same subnet as VLAN 3, set the gateway to the VLAN 3 virtual address, shut down the interface connecting SW2 and SW4, and ping... Figure 2 If the L0 address of the simulated external network is not accessible, a successful ping indicates that the primary / backup preemption mechanism is not in effect.

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