[0025] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the embodiments will be described in detail below with reference to the accompanying drawings. Obviously, the contents described below are some examples or embodiments of this specification. For ordinary technicians in this field, without paying creative work, the technical solutions or means disclosed in this specification can also be applied to other scenarios based on these technical contents.

[0026] It should be understood that the "system", "device", "unit" and / or "module" used in this specification is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the above words can be replaced by other expressions.

[0027] Unless otherwise specified, technical terms used in this specification to describe components, elements, etc. do not refer to the singular, but may also include the plural. Generally speaking, terms such as "include", "comprise", etc. only indicate that the steps, elements, or components that have been clearly identified are included, and these steps, elements, and components do not constitute an exclusive list, such as the method or device described may also include other steps or components.

[0028] Flowcharts are used in this specification to illustrate the operation steps performed by the device or system of the relevant embodiments, but unless otherwise specified, the order used to describe these steps should not be understood as a limitation on the order in which the steps are performed. A person of ordinary skill in the art can adjust the order in which these steps are performed based on the knowledge and information conveyed by the embodiments of this specification, and the above adjustment includes but is not limited to swapping the order, merging multiple steps, and splitting a certain step.

[0029] Power over Ethernet (POE) is a technology that transmits data and power simultaneously through standard Ethernet cables, such as Cat5, Cat6, etc. It enables network devices such as IP cameras, wireless access points, VoIP phones, etc. to achieve power supply and data transmission through the same network cable, thereby simplifying the wiring and installation process. In the Ethernet power supply network, there are usually POE power supply equipment (Power Sourcing Equipment, PSE) and POE powered devices (Powered Device, PD), where POE power supply equipment refers to a device that provides power to connected devices through Ethernet cables, which can include devices such as POE switches, and POE powered devices refer to devices that receive power through Ethernet cables, which can include wireless access points, IP cameras, etc. There are multiple standards for Power over Ethernet, such as 802.3af and 802.3at. 802.3af is the earliest standard for Power over Ethernet. The maximum power of the powered device allowed to be connected is 15.4W, which is suitable for low-power powered devices. 802.3at is an enhanced version of the Power over Ethernet standard. The maximum power of the powered device allowed to be connected is extended to 30W and is backward compatible with the 802.3af standard, which can support more powered devices.

[0030] Figure 1 is an exemplary structural diagram of an Ethernet power supply network according to some embodiments of this specification. Figure 1 As shown, the Power over Ethernet network 100 may include a POE switch 110 and a plurality of powered devices 120 connected to the POE switch, wherein the POE switch 110 may supply power to the connected powered devices 120 according to a set maximum output power.

[0031] In order to detect the use stability of the powered device in the Ethernet power supply network, it is necessary to verify whether the powered device can be powered on again after an accidental power failure, for example, the output power fluctuation of the POE switch causes insufficient power to be provided to the powered device, resulting in whether the powered device can be powered on again after normal power is restored after power failure during use. In some related embodiments, the power on and off of the POE switch can be controlled by a control device such as a timing socket, so that the powered devices under all ports of the POE switch are powered on and off together to test the use stability of the powered device. In other related embodiments, in order to be more in line with actual application scenarios, a method of developing test software can be used to use software to control each port of the POE switch to independently control the power on and off of the powered device, so as to simulate the scenario in which some powered devices in actual application scenarios can be powered on again after an accidental power failure. However, this method has high requirements for system testers, requiring system testers to have test software or test script development skills, and the software can usually only achieve pseudo-randomness.

[0032] Based on the relevant descriptions of the aforementioned embodiments, since using software to control each port of the POE switch cannot completely simulate the random power-on and power-off scenarios of the powered devices in actual applications, and the development of test software has high requirements on the skill level of the testers, in order to conveniently implement random power-on and power-off tests on the powered devices to evaluate the stability of the powered devices, some embodiments of this specification provide Ethernet power supply network equipment testing methods. Figure 2 is an exemplary flow chart of a method for testing an Ethernet power supply network device according to some embodiments of this specification. In some embodiments, Figure 2 The process 200 shown can be applied to Figure 1 In some embodiments, as shown in the Ethernet power supply network. Figure 2 As shown, process 200 may include the following steps.

[0033] Step 210: Setting the maximum output power of the POE switch so that at least some of the powered devices enter a random power-on and power-off state. In some embodiments, step 210 can be implemented by the setting unit 910 .

[0034] In some embodiments, by setting the maximum output power of the POE switch, at least some of the powered devices in the Ethernet power supply network can enter a random power-on and power-off state due to insufficient output power of the POE switch. Figure 3 This is a screenshot of some exemplary operation logs of a POE switch according to some embodiments of this specification. Figure 3As shown in the figure, when the output power of the POE switch is insufficient, the powered devices that do not receive sufficient power supply will enter the random power-on and power-off state, and the power-on and power-off processes of these powered devices in the random power-on and power-off state will be recorded as events (EVENT) by the operation log of the POE switch. For example, for the powered device "GE0 / 0 / 9", it experienced a power-off process at "11:56:48", that is, Figure 3 The corresponding "GE0 / 0 / 9 poe power switch to off" event in the output; and then the power is restored at "11:57:16", that is, Figure 3 The corresponding "GE0 / 0 / 9 poe power switch to on" event in the figure; then it experienced the power-off process again at "11:57:54", that is, Figure 3 For other powered devices that cannot receive sufficient power due to insufficient output power of the POE switch, such as "GE0 / 0 / 8" and "GE0 / 0 / 12", the same event is also displayed in the following example: Figure 3 The random power-on and power-off state is entered and the random power-on and power-off event is triggered during the time period from "11:56:27" to "11:58:54" as shown. In some embodiments, the maximum output power set for the POE switch needs to be less than the default maximum output power of the POE switch, wherein the default maximum output power refers to the maximum power that the POE switch can provide to the powered device connected through the Ethernet power supply protocol without any special configuration. Generally speaking, when POE outputs at the default maximum output power, it can satisfy all or most of the powered devices in the Ethernet power supply network to enter a stable working state. Therefore, limiting the set maximum output power to less than the default maximum output power can make at least some of the powered devices unable to obtain sufficient power supply from the POE switch and enter the random power-on and power-off state, thereby realizing a true simulation of the random power-on and power-off state of some powered devices.

[0035] In some embodiments, taking a 24-port POE switch under the 802.3at standard as an example, its default maximum output power is 500W, which can support powering 24 powered devices with a peak power consumption not exceeding 16W. When setting the maximum output power of the POE switch, the maximum output power of the POE switch can be set to 40W, so that only a small number of powered devices can be in a stable working state after being powered on first, and the remaining powered devices will enter a random power-on and power-off state. In some embodiments, in the process of setting the maximum output power of the POE switch, in order to ensure that the connected powered devices can enter the random power-on and power-off state and meet the power-on conditions, it is necessary to make the maximum output power of the POE switch at least meet the required power consumption of any one of the connected powered devices to successfully start powering on, that is, the minimum value of the maximum output power of the POE switch set should be greater than the required power consumption of any one of the connected powered devices to successfully start powering on. In some embodiments, the powered device that enters the random power-on and power-off state can be autonomously selected by adjusting the power-on sequence of the powered devices, which is not limited here.

[0036] In some embodiments, the maximum output power of the POE switch can be set by a test terminal device connected to the POE switch, wherein the test terminal device may include but is not limited to electronic devices with a human-computer interaction interface such as a desktop computer, a smart phone, and a laptop computer. The test terminal device can select the corresponding maximum output power and set the POE switch by receiving a test instruction issued by a test user. In some embodiments, the maximum output power of the POE switch can also be configured by inputting parameter information such as the maximum output power value in the human-computer interaction interface carried by the POE switch itself.

[0037] In some embodiments, the setting unit 910 can automatically set the maximum output power of the POE switch. In some embodiments, the setting unit 910 can set the maximum output power of the POE switch to be greater than the power required for any powered device to successfully start and power on, and less than the power required for any powered device to be in a stable working state. In some embodiments, the setting unit 910 can set the number of powered devices that are in a stable working state during the test (such as 2, 3, 5, etc.), and determine the first power required based on the number of powered devices that are in stable working state; then the setting unit 910 can set the value of the maximum output power of the POE switch to the sum of the first power and the excess power value, wherein the excess power is greater than the power required for any powered device to successfully start and power on, and less than the power required for any powered device to be in a stable working state.

[0038] Step 220 : Based on the stability parameter information of the powered device in the random power on and off state, evaluate the stability of the powered device in the random power on and off state. In some embodiments, step 220 may be implemented by the stability evaluation unit 920 .

[0039] In some embodiments, the stability parameter information may include relevant parameter information reflecting the power-on and power-off conditions of the powered device in the random power-on and power-off state, for example, it may include the power-on time information of the powered device, the power-off time information of the powered device, the status information of whether the powered device is successfully powered on, etc. In some embodiments, the stability parameter information may be obtained through a test terminal device connected to a POE switch or a powered device, and the stability of the powered device in the random power-on and power-off state may be evaluated through a pre-set evaluation scheme in the test terminal device. The following will further explain the method of evaluating the stability of the powered device in the random power-on and power-off state in conjunction with the embodiments.

[0040] Figure 4 is an exemplary flow chart of evaluating the stability of a powered device under random power-on and power-off states according to some embodiments of this specification. Figure 4 As shown, process 400 may include the following steps.

[0041] Step 410: Based on the operation log of the POE switch, obtain the power-on and power-off log parameters of the powered device in the random power-on and power-off state. In some embodiments, the power-on and power-off log parameters corresponding to the powered device in step 410 belong to one of the stability parameter information mentioned in the above embodiments. In some embodiments, step 410 can be implemented by the stability evaluation unit 920.

[0042] In some embodiments, the POE switch can continuously monitor the power-on and power-off conditions of each connected powered device, for example, a powered device experiences a power-off event at the first moment, and a powered device experiences a power-on event at the second moment, etc. The recorded information of these power-on and power-off conditions forms the corresponding power-on and power-off log parameters of each powered device under the random power-on and power-off state. In some embodiments, the power-on and power-off log parameters may include the power-on and power-off events of the powered device under the random power-on and power-off state and the corresponding occurrence time of each power-on and power-off event, and these power-on and power-off log parameters may be recorded in the operation log of the POE switch. In some embodiments, the above-mentioned power-on and power-off log parameters can be obtained by testing the terminal device to read the operation log of the POE switch.

[0043] Step 420: Based on the power-on and power-off log parameters, determine whether the powered device can be powered on again after each power-off process in the random power-on and power-off state: if so, determine that the powered device is stable in the random power-on and power-off state. In some embodiments, step 420 can be implemented by the stability evaluation unit 920.

[0044] In some embodiments, for each powered device in the Ethernet power supply network, the power-on and power-off log parameters may include the corresponding time of each power-on process and power-off process experienced by the powered device in the random power-on and power-off state, and the test terminal device may sort the power-on and power-off log parameters according to the time information in the power-on and power-off log parameters, thereby obtaining the interval arrangement sequence of the power-on process and the power-off process of the powered device in the random power-on and power-off state. In some embodiments, based on the interval arrangement sequence of the power-on process and the power-off process, if the powered device experiences a power-on process after each power-off process in the random power-on and power-off state, it means that the powered device can be restored to power on after each power-off process in the random power-on and power-off state with sufficient power support, which also means that if the powered device is powered off due to insufficient power supply in daily use, it can be restored to power on after the power supply is restored, and it can be judged that the powered device is stable in the random power-on and power-off state.

[0045] Based on the description of the above embodiments, the stability judgment method provided by process 400 can judge whether the powered device can be powered on again after being powered off based on the operation log of the POE switch. For the powered device, being able to be powered on again after being powered off does not mean that the powered device can be started normally and enter a normal working state after being powered on. There may be a scenario where the powered device cannot be started normally or enter a normal working state after being powered on, which affects the stability judgment of the powered device.

[0046] In order to further verify whether the powered device can be successfully started when it is powered on again, some embodiments of this specification provide another method for evaluating the stability of the powered device in a random power-on and power-off state. Figure 5 is another exemplary flow chart of evaluating the stability of a powered device in a random power-on and power-off state according to some embodiments of this specification. Figure 5 The process 500 shown can be performed as follows Figure 4 The process 400 shown in FIG. 4 is then executed, and may also be executed independently of the process 400 shown in FIG. Figure 4 The process 400 shown in FIG. 4 is performed separately. In some embodiments, as Figure 5 As shown, process 500 may include the following steps.

[0047] Step 510: Based on the device log of the powered device, obtain the startup status log parameter of the powered device during the startup process. In some embodiments, the startup status log parameter in step 510 is one of the stability parameter information mentioned in the above embodiments. In some embodiments, step 510 can be implemented by the stability evaluation unit 920.

[0048] In some embodiments, the startup process of the powered device may include a boot loader startup process, a kernel startup process, and a software version startup process, wherein the boot loader startup process is the first program executed when the powered device is started, responsible for initializing the hardware and loading the operating system, which may specifically include power-on self-test, loading the boot loader, executing the boot loader, loading the kernel, etc.; the kernel startup process is the process in which the kernel starts to initialize and manage the hardware after the boot loader loads the kernel, which may specifically include kernel initialization, memory configuration management, device driver loading, etc.; the software version startup process is the last program executed when the powered device is started, involving the version management of the operating system and application, which may specifically include version detection, configuration file reading, selecting the startup version and loading the startup version, etc. In some embodiments, the startup status log parameters may include the status information of whether each startup process of the powered device is executed normally during each startup process, and these startup status log parameters may be recorded in the device log of the powered device. In some embodiments, the above startup status log parameters may be obtained by testing the terminal device to read the device log.

[0049] Step 520: Based on the startup state log parameters, determine whether the startup state log parameters meet the standard startup state parameters during the startup process of the powered device switching from the power-off state to the power-on state in the random power-on and power-off state: if so, determine that the powered device has stability in the random power-on and power-off state. In some embodiments, step 520 can be implemented by the stability evaluation unit 920.

[0050] In some embodiments, it is possible to determine whether the powered device is started normally by determining whether the device log contains the first parameter information corresponding to the boot loader startup process, the second parameter information corresponding to the kernel startup process, and the third parameter information corresponding to the software version startup process. Among them, the first parameter information is used to indicate that the boot loader startup process has been successfully started, for example, it can be a field or command line that indicates that the boot loader has been successfully started; the second parameter information is used to indicate that the kernel startup process has been successfully started, for example, it can be a field or command line that indicates that the kernel has been successfully started; the third parameter information is used to indicate that the software version startup process has been successfully started, for example, it can be a field or command line that indicates that the software version has been successfully started. In some embodiments, it is possible to determine whether the first parameter information, the second parameter information, and the third parameter information are in the device log by traversing the device log and identifying whether there are relevant fields or command lines in the device log. In some embodiments, if the device log contains the above-mentioned first parameter information, second parameter information and third parameter information at the same time, it means that the boot loader startup process, kernel startup process and software version startup process of the powered device are all successfully started, and the powered device is successfully started and enters normal working state after power-on, that is, the startup status log parameters of the powered device meet the standard startup status parameters. At this time, it can be judged that the powered device can be successfully powered on and successfully started to enter normal working state under random power-on and power-off states, and is stable.

[0051] Based on the relevant description of the above-mentioned embodiments, the Ethernet power supply network device testing method provided by process 200 can provide a random power-on and power-off test environment for some powered devices, and test the stability of whether the powered device in the random power-on and power-off state can be normally restored to power after power-off, so as to obtain the stability of the powered device in the random power-on and power-off state. Considering that in the test process corresponding to process 200, whether the powered device in the random power-on and power-off state is powered on is random, in some embodiments, a single powered device may never experience the power-on process in the test process corresponding to process 200; in other embodiments, the situation that a single powered device is not powered on again after powering off in the test process corresponding to process 200 may be because the powered device cannot be powered on again due to a fault, or because the powered device has not experienced the power-on process again due to the randomness of power-on. In order to eliminate the influence of power-on randomness and more comprehensively evaluate the stability of the powered device, some embodiments of this specification provide another Ethernet power supply network device testing method. Figure 6 is an exemplary flow chart of another method for testing an Ethernet power supply network device according to some embodiments of this specification. In some embodiments, Figure 6 The process 600 shown can be performed as follows Figure 2 The process 200 shown is then executed. In some embodiments, Figure 6 As shown, process 600 may include the following steps.

[0052] Step 610: Update the maximum output power of the POE switch to enable all powered devices to enter a stable power-on state. In some embodiments, step 610 can be implemented by the setting unit 910.

[0053] In some embodiments, in order to eliminate the influence of power-on randomness, after the execution of process 200 is completed, the maximum output power of the POE switch can be updated by testing the terminal device, so that the POE switch can provide sufficient output power for all powered devices, so that all powered devices can enter a stable power-on state, thereby covering the scenario where the powered device fails to go through the power-on process due to power-on randomness, and can more comprehensively evaluate the stability of the powered device.

[0054] In some embodiments, taking a 24-port POE switch under the 802.3at standard as an example, it can support powering 24 powered devices with a peak power consumption not exceeding 16W. When updating the maximum output power of the POE switch, the maximum output power of the POE switch can be directly updated to the default maximum output power of 500W, or the maximum output power of the POE switch can be updated to 390W, so that the updated maximum output power can simultaneously support all powered devices to start and run at peak power consumption.

[0055] Step 620 : Determine whether the powered device can be restored when it switches from the random power-on and power-off state to the stable power-on state, so as to obtain the stability of the powered device when it switches from the random power-on and power-off state to the stable power-on state. In some embodiments, step 620 can be implemented by the stability evaluation unit 920 .

[0056] In some embodiments, for a normal powered device, when the power-on and power-off state is converted to a stable power-on state, the powered device should be able to resume power-on because the POE switch provides a stable output power; if the powered device cannot resume power-on normally when it is converted from a random power-on and power-off state to a stable power-on state, it means that the powered device may not be able to resume work normally due to a fault or other reasons, and the stability of use in daily working conditions is poor, and further testing or troubleshooting of the powered device is required. Therefore, the stability of the powered device can be evaluated by judging whether the powered device can resume power-on when it is converted from a random power-on and power-off state to a stable power-on state. The following will further explain the method for judging whether the powered device can resume power-on when it is converted from a random power-on and power-off state to a stable power-on state in combination with the embodiments.

[0057] Figure 7The present invention is an exemplary flow chart for determining whether a powered device can be powered on again when it switches from a random power-on and power-off state to a stable power-on state according to some embodiments of the present specification. Figure 7 As shown, process 700 may include the following steps.

[0058] Step 710 : Based on the default IP address of the powered device, send multiple detection packets to the powered device. In some embodiments, step 710 may be implemented by the stability evaluation unit 920 .

[0059] In some embodiments, the test terminal device can be connected to the LAN interface of the powered device that needs to be tested to achieve network connection between the test terminal device and the powered device, and then multiple detection packets are sent to the powered device according to the default IP address of the powered device. In some embodiments, the LAN interface (Local Area Network Interface) refers to the physical interface of the powered device for connecting to the local area network, which allows the powered device to communicate with other devices, such as the test terminal device, by wired or wireless means. In some embodiments, the default IP address (Default IP Address) refers to the default IP address used by the powered device when no network configuration is performed, which can be used for the initial configuration and management of the powered device. Considering that process 700 is a judgment on whether the powered device can be restored to power on when it is converted from a random power-on and power-off state to a stable power-on state, using the default IP address to send the detection packet can ensure that the detection packet is smoothly sent to the powered device.

[0060] Step 720 : Based on the feedback information of the powered device for the detection packet, determine whether the powered device can be powered on again when it switches from the random power-on and power-off state to the stable power-on state. In some embodiments, step 720 can also be implemented by the stability evaluation unit 920 .

[0061] In some embodiments, the powered device can give corresponding feedback information based on the received detection packet, and the feedback information can include the number of bytes of the detection packet received by the powered device each time, the estimated round-trip time of the data from sending the detection packet to receiving the feedback information each time, the maximum number of hops allowed for the detection packet in the network, and other information. The test terminal device can judge whether the powered device can be restored to power on when it switches from the random power-on and power-off state to the stable power-on state based on the above feedback information. In some embodiments, the test terminal device is set to continuously send a number of 32-byte detection packets to the powered device. If the feedback information shows that the number of bytes of the detection packet received by the powered device each time is 32 bytes, and the estimated round-trip time of the data is within 1ms or other lower delays, it means that the test terminal device can establish a stable connection with the powered device based on the default IP address of the powered device, and the powered device can stably receive the detection packet completely, that is, the network connection between the powered device and the test terminal device is reliable and stable, which can indicate that the powered device successfully restores power and can work normally when it switches from the random power-on and power-off state to the stable power-on state. In some embodiments, based on the feedback information of the powered device, it can be set that when the packet loss rate of the detection packet is less than a first preset threshold and the network delay time between the test terminal device and the powered device is less than a second preset threshold, it can be determined that the powered device can successfully restore power when it switches from a random power-on and power-off state to a stable power-on state.

[0062] In some embodiments, determining whether the powered device can be restored to power on when it switches from a random power-on and power-off state to a stable power-on state is not limited to being implemented by sending a detection packet to the powered device by the test terminal device. Figure 8 is another exemplary flow chart for determining whether a powered device can be powered on again when it switches from a random power-on and power-off state to a stable power-on state according to some embodiments of this specification. Figure 8 As shown, process 800 may include the following steps.

[0063] Step 810: Establish a communication connection with the powered device based on a preset network protocol.

[0064] In some embodiments, the test terminal device can establish a communication connection with the powered device through the Telnet protocol, where the Telnet protocol is a protocol used for remote communication on the network, which allows the test terminal device to remotely interact with the powered device through a command line interface, and is mainly used to remotely log in to the powered device and execute commands and / or manage the powered device system.

[0065] Step 820: When the software version number information of the powered device can be obtained based on the communication connection, it is determined that the powered device can be restored to power on when the random power on and off state is converted to a stable power on state.

[0066] In some embodiments, based on the relevant description of the above embodiments, the startup process of the powered device may include a boot loader startup process, a kernel startup process, and a software version startup process, wherein the software version startup process is the last stage of the entire startup process, and the successful startup of the software version startup process indicates that the startup process of the powered device has been completed and successfully powered on, and the software version number information of the powered device can be obtained at this time. In the above step 820, if the test terminal device can successfully obtain the software version number information of the powered device based on the communication connection, it means that the powered device has completed the entire startup process and successfully powered on, that is, it can be said that the powered device can be restored when it is converted from a random power-on and power-off state to a stable power-on state.
