Please refer to Figure 1 and Figure 2. FIG. 1 is a schematic diagram of a network device 100 for temporarily accessing network settings according to a first embodiment of the present invention. FIG. 2 is a flowchart of a method for temporarily accessing network settings of a network device according to a first embodiment of the present invention. The network device 100 (hereinafter referred to as the network device 100 ) for temporarily accessing the network settings includes at least one first network connection port 110 (although a plurality of them are described here as an example, but in some embodiments there may be only one network connection port 110 ), the second network connection port 120 , the first network management unit 130 , the second network management unit 140 , the storage unit 150 and the processing unit 160 . The first network management unit 130 is electrically connected to the storage unit 150 and the first network connection port 110 . The second network management unit 140 is electrically connected to the storage unit 150 and the second network connection port 120 . The processing unit 160 is electrically connected to the storage unit 150 , the first network connection port 110 , the second network connection port 120 , the first network management unit 130 and the second network management unit 140 . The processing unit 160 is a computing unit capable of executing software programs.

The first network connection port 110 and the second network connection port 120 are connection holes supporting an Ethernet interface, and can be connected with a network cable having an RJ45 connector, for example. In the normal working mode of the network device 100 , the first network connection port 110 can be correspondingly connected to at least one external network device 300 to perform functions of the network device 100 . Here, the network device 100 may be, for example, a hub (Hub), a switch (Switch), an IP sharer, a router (Router), a wireless access point (Wireless Access Point, WAP) and the like. The networking device 300 is a device capable of network connection, such as a desktop computer, a notebook computer, a workstation, a server, and the like.

The first network management unit 130 and the second network management unit 140 are management units capable of supporting network transmission protocols, and each have a storage space (eg, random access memory (RAM)). The storage space of the first network management unit 130 can store the network setting corresponding to the first network connection port 110 (hereinafter referred to as the first network setting), so that the first network connection port 110 can communicate with the connected network according to the first network setting. devices to communicate. Similarly, the storage space of the second network management unit 140 can store the network setting corresponding to the second network connection port 120 (hereinafter referred to as the second network setting), so that the second network connection port 120 can be configured according to the second network setting Communicate with connected devices.

The storage unit 150 is a non-volatile memory, such as flash memory, electrically erasable programmable read-only memory (EEPROM) or/and read-only memory (ROM), and stores a management network address and a default network address. Here, the management network address and the default network address can be static addresses or dynamic addresses. The management network address is stored in a memory that can be rewritten and changed, such as flash memory, EEPROM, etc.; the default network address can be stored in a read-only memory that cannot be rewritten and changed to ensure that it will not change , but it is still possible to store in rewritable and changeable memory. The default network address is stored in the storage unit 150 when the network device 100 leaves the factory, such as 192.168.1.1. The management network address can be a network address preset by the network device 100 when it leaves the factory, or a network address changed by a subsequent user.

In the aforementioned working mode, the first network management unit 130 stores a first network setting, and the first network setting includes a management network address, so that when the setting device 200 is connected to one of the first network connection ports, it can manage The network address is used as the destination address to communicate with the network device 100 (refer to step S410 in FIG. 2 ). Therefore, when the user wants to set the network device 100 (such as changing the management network address, modifying the administrator account password, etc.), he can use the setting device 200 to connect to the network device 100 through the first network connection port 110, according to to operate. However, if the user forgets when the management network address is, the aforesaid operation cannot be performed, and needs to be performed in a subsequent manner. Here, the setting device 200 may be a device capable of network connection, such as a desktop computer, a notebook computer, a workstation, a server, and the like.

Also in the working mode, the second network management unit 140 pre-stores the second network settings, so the second network connection port 120 is normally in an idle state, and does not provide network communication functions in the working mode. The processing unit 160 detects whether a mode switching condition is satisfied in the working mode. Here, the mode switching condition is that the setting device 200 is connected to the second network connection port 120 . When the mode switching condition is satisfied, the network device 100 enters the temporary management mode from the working mode. (Refer to step S420 of FIG. 2 ) Therefore, under this mode switching condition, after the user connects the setting device 200 to the second network connection port 120, the processing unit 160 detects that the mode switching condition is satisfied, and then Enter temporary management mode.

In the temporary management mode, the processing unit 160 controls the second network management unit 140 to store the second network configuration corresponding to the second network connection port 120 . That is, the processing unit 160 reads the default network address stored in the storage unit 150, and writes the default network address into the second network setting (ie, the second network setting includes the default network address). Therefore, the setting device 200 can preset the network address as the destination address to communicate with the network device 100 . (refer to step S430 of Fig. 2)

Therefore, the user can operate the setting device 200 to transmit the control command to the network device 100 . The processing unit 160 can execute a feedback action based on the control instruction sent by the setting device 200 . (refer to step S440 of Fig. 2)

For example, the user operates the web browser of the setting device 200 , and inputs a default network address in the web browser to connect to the network device 100 . After passing the administrator identity authentication procedure (for example, verifying the administrator account and password), the setting device 200 can issue control instructions to the network device 100 through a web console (web console), web interface (web UI), and the like. In one embodiment, the feedback action corresponding to the control command is to return a data packet including the management network address or to change the management network address in the first network configuration based on the control command. That is to say, because the user forgets the management network address, a control command for querying the management network address can be issued, so that the processing unit 160 returns the data packet of the management network address, and the setting device 200 receives the returned data packet, and can Displays the management network address. The user can then know what the management network address is, so as to connect to the network device 100 using the queried management network address later. Alternatively, the user can issue a control command to change the management network address, and send the management network address to be set to the network device 100, and the processing unit 160 can replace the original management network address with the new one sent by the setting device 200. The management network address is used for subsequent connection to the network device 100 using the newly set management network address. However, the feedback actions referred to in the embodiments of the present invention are not limited thereto, and may also be other actions that can be performed within the management authority, such as performing other network settings, setting account passwords, and the like.

Referring to step S450 of FIG. 2 , in the temporary management mode, the processing unit 160 also detects whether the above-mentioned mode switching condition is lifted, and when the mode switching condition is lifted (here, the connection between the setting device 200 and the second network connection port 120 If the connection relationship between them is interrupted, such as unplugging the network cable), return to the working mode. Accordingly, even if the user forgets to manage the network address, there is no need to reset the network device back to the factory state, and any original settings are prevented from being reset. After returning to the working mode, the first network connection port 110 can continue to be connected to the network connection device 300 to perform the proper functions of the network device 100 .

In an embodiment, the mode switching condition may further include that each first network connection port 110 disconnects from the network connection device 300 . That is to say, each of the first network connection ports 110 is in an idle state, and is not connected to the networking device 300 . In this way, in addition to the second network connection port 120 connected to the setting device, all the first network connection ports 110 also need not be connected to other devices before the network device 100 enters the temporary management mode, which can prevent the user from mistaking the device. Connecting to the second network connection port 120 triggers a mode change, thereby affecting the normal operation of the network device 100 .

In one embodiment, in the temporary management mode, the processing unit 160 clears the first network setting of the first network management unit 130 to avoid network address conflicts (for example, the original management network address is the same as the default network address). After returning to the working mode, the processing unit 160 will reset the first network setting of the first network management unit 130 according to the management network address stored in the storage unit 150 (that is, return to the setting before entering the temporary management mode. Here, besides the management network address, the first network setting may also include but not limited to network mask, network gateway, Dynamic Host Configuration Protocol (DHCP) and other settings.

In one embodiment, besides managing the network address, the user may also forget the account password of the administrator. Even if the connection is successful with the preset network address in the above manner, the network device 100 still cannot be operated. For this, the storage unit 150 can also store a management account password and a temporary account password. The management account password refers to the administrator account password that the user needs to use, and the temporary account password is the account password preset by the network device 100 when it leaves the factory. Therefore, the temporary account password can be stored in a read-only memory that cannot be rewritten or changed, but it is still possible to store it in a memory that can be rewritten and changed. In the working mode, the processing unit 160 will verify whether the setting device 200 is logged in with the management account and password, and the user is allowed to make settings only if the login is successful. If in the temporary management mode, the processing unit 160 will use the temporary account and password to verify the login of the setting device 200 . Therefore, following the description of the aforementioned first embodiment, in the temporary management mode, the user can log in the network device 100 with a temporary account and password in addition to connecting with the default network address.

FIG. 3 is a schematic diagram of a network device 100 for temporarily accessing network settings according to a second embodiment of the present invention.

Compared with the aforementioned first embodiment, the network device 100 of this embodiment does not have the second network connection port 120 and the second network management unit 140 , but a trigger unit 170 is added. Therefore, in this embodiment, the setting device 200 is connected to the first network connection port 110 . These differences will be described later, and for other parts, please refer to the above description, and will not be repeated here.

The trigger unit 170 is electrically connected to the processing unit 160 and can generate a trigger signal in response to a trigger condition. Here, depending on the type of the trigger unit 170 , the trigger conditions are different. In one embodiment, the trigger unit 170 can be a switch or a button with at least two states. Instead, the trigger signal can be generated when the trigger unit 170 changes from the first state to the second state due to the user's input. For example, pressing a button generates a trigger signal for a voltage change; switching a switch generates a trigger signal for an open circuit or a short circuit. In another embodiment, the trigger unit 170 can be a timer, and can generate a timeout trigger signal after a predetermined period of time since the setting device 200 is connected to the first network connection port 110 .

The processing unit 160 can detect whether the aforementioned trigger signal is generated in the working mode, and detect whether a mode switching condition is also satisfied. Here, the mode switching condition may be that the first network connection port 110 is connected to the setting device 200 . If both are satisfied, then enter the temporary management mode from the working mode. In the temporary management mode, the processing unit 160 clears the management network address in the first network setting stored by the first network management unit 130, and sets the first network setting to include a default network address to be compatible with the setting device 200 communication. In other words, the first network setting corresponding to the first network connection port 110 is changed from including the management network address to including the default network address. The processing unit 160 can execute the feedback action based on the control command sent by the setting device 200, and detect whether the mode switching condition is released (here, the connection relationship between the setting device 200 and the first network connection port 110 is interrupted, such as unplugging The network line between them), and return to the working mode when the mode switching condition is released. Accordingly, even if the user forgets to manage the network address, there is no need to reset the network device back to the factory state, and any original settings are prevented from being reset. After returning to the working mode, the first network connection port 110 can continue to be connected to the network connection device 300 to perform the proper functions of the network device 100 .

To sum up, according to the network device 100 and the method for temporarily accessing the network settings of the network device 100 according to the embodiments of the present invention, when the user forgets the management network address, he can still enter the temporary management mode and learn the management network address again. Or change the management network address. In some embodiments, if the user also forgets the password of the administrator account, he can log in with a temporary account password in the temporary management mode. By switching between the temporary management mode and the working mode, there is no need to reset the network device 100 to the factory state, and any original settings are freed from being reset.
