Background technique

A router is a device connected to various LANs and WANs in the Internet. It will automatically select and set routes according to the channel conditions, and send signals in the order of the best path. The main interfaces of the router include LAN interface, WAN interface and router configuration interface. LAN interface types include standard network interfaces such as Ethernet, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet. In each network, it can support interfaces of different media standards, such as RJ-45 interface, optical fiber interface, thick coaxial cable interface, etc. The WAN interface includes a synchronous serial interface and an asynchronous serial interface. The configuration interface has a control interface Console, and the control interface Console is usually used to connect the interface with a computer using a dedicated connection line when performing basic configuration on the router.

Because the router has many ports, multiple computers are connected to the ports of the router by cables. For a router, it can bind the MAC address of the computer connected to it and the IP address it assigns to the computer. By binding the MAC address and IP address of the computer, provide the computer connected to it with the total number of computers connected to it and the parameters of the computer (such as the MAC address and IP address of the computer). Users can connect more computers through the port of the router, which will increase the number of cables accordingly. When the computer is too far away from the router, the length of the cable needs to be increased accordingly. When a user needs to remove a certain computer, it is difficult for the user to accurately find the physical interface of the router connected to the computer due to too many or too long cables connected to the router. It is also impossible to operate on the physical interface to which the computer is connected. When the user searches for the port connected to the computer, it is easy to directly disconnect other computers from the router, which affects the user experience.

The client computer referred to in this application may be a computer, a mobile phone, a tablet, a laptop computer, and the like.

FIG. 1 is a schematic structural diagram of a communication system composed of a router and a client in an application scenario provided by an embodiment of the present application.

The communication system composed of routers and clients shown in FIG. 1 includes a router 30 and a plurality of clients 40 connected to the router 30 through cables 501. As shown in the figure, three clients 40 are connected to the router 30 with Wired connection.

The three clients 40 are all connected to the LAN interface 30301 , the LAN interface 30302 and the LAN interface 30303 of the LAN interface 3030 through cables 501 .

The interface 303 (physical interface) of the router 30 includes but not limited to a LAN interface 3030 , a WAN interface 3031 and a router configuration interface 3032 . It should be noted that the number of LAN interface 3030, WAN interface 3031 and router configuration interface 3032 is not limited to one. As provided in the embodiment of the present application, there are three LAN interfaces 3030 in the application scenario in FIG. 1 , which are LAN interface 30301 , LAN interface 30302 , and LAN interface 30303 . WAN interface 3031 includes three interfaces and router configuration interface 3032 includes one interface

According to some embodiments of the present application, the LAN interface 3030 , the WAN interface 3031 and the router configuration interface 3032 of the router 30 are used to connect to the client 40 respectively.

In the case that the router 30 is capable of wireless routing, there may also be a client 50 connected to the router 30 through a wireless method 500 .

Whether it is a client computer connected to the router in a wired or wireless manner, it can query the physical interface information connected to the router itself, and query the physical interface information of other electronic devices when the authority allows. For example, when a device is running as an administrator of the router, it can query the physical interface information of all electronic devices connected to the router. The specific structures of the router and the client included in Figure 1 in the embodiment of the present application are described below:

Referring to FIG. 2( a ), FIG. 2( a ) is a schematic diagram of a hardware structure of a router 30 disclosed in an embodiment of the present application.

The router 30 includes: a memory 301 , a processor 302 , an interface 303 (physical interface), a power module 306 and a switch 307 . Interfaces 303 (physical interfaces) include but are not limited to LAN interface 3030 , WAN interface 3031 and router configuration interface 3032 . Router configuration interface 3032 includes a console port and an auxiliary port.

It can be understood that, the structure shown in the embodiment of the present application does not constitute a specific limitation on the router 30 . In other embodiments of the present application, the router 30 may include more or fewer components than shown in the figure, or combine certain components, or separate certain components, or arrange different components. The illustrated components can be realized in hardware, software or a combination of software and hardware.

In some embodiments of the present application, the memory 301 may adopt non-volatile memory, random access memory, flash memory and read-only memory.

The random access memory will discard its information when the router is started or the power supply gap is. The read-only memory stores the startup software of the router. The startup software is the first software that the router runs. It is responsible for the router to enter the normal working state. The system is saved in the random access memory as a backup, so that it can be used as a backup when the operating system cannot be used. The router 30 has a Dynamic Host Configuration Protocol server (Dynamic Host Configuration Protocol, DHCP server).

The random access memory can be used as a storage device for an IP pool. When the client 40 requests the router 30 to assign an IP address, the DHCP server of the router 30 selects an IP address from the IP pool and assigns it to the client 40 . In addition, various parameters such as the MAC address of the client 40, the IP address assigned to the client 40 by the router 30, and the binding relationship between the MAC address and the IP address of the client 40 can also be stored in the random access memory.

In addition, the image resource data (position of the LAN interface on the router, interface parameters, appearance, etc.) ), the mapping relationship between physical interfaces and virtual interfaces, etc.

ROM is usually set on one or more chips, soldered on the motherboard of the router

The main purpose of the flash memory is to store the operating system of the router 30 to maintain the normal operation of the router. If the router is equipped with a flash memory, it is mainly used to guide the default position of the router operating system. As long as the capacity of the flash memory is sufficient, multiple operating system images can be saved. To provide multiple boot options, wherein, the operating system of the router 30 adopts the Linux operating system.

The main function of the non-volatile memory is to save the configuration data (startup configuration) read in when the operating system is started. The random access memory is mainly used as the storage area of the operating system table and buffer. The operating system can meet all the conventional storage needs through the random access memory, so that the router can quickly access the information. Among them, the storage speed of the random access memory is better than the above mentioned three.

It can be understood that parameters such as the IP pool of the router, the parameters of the client 40, the picture resource data, and the binding relationship between the MAC address and the IP address of the client 40 can also be stored in a non-volatile memory or other types of memory , the embodiment of the present application is not limited here.

The processing unit in the processor 302 (may be referred to as a MAC processing unit (including a hardware part (may be referred to as GMAC hardware) and a software part (may be referred to as GMAC software)) can convert the data packet of the router 30 into a bit stream and send it to the switch 307. The switch 307 resolves the bitstream from the MAC processing unit to obtain the MAC address of the client. The router 30 searches for the corresponding client 40 of the MAC address, and sends corresponding data (such as IP address) to the corresponding physical interface , sent to the client 40 through the physical interface.

As shown in FIG. 2( a ), the processor 302 is connected to the switch 307 and the interface 303 , and the switch 307 is connected to the interface 303 . The processor 302 is connected to the client 40 through the switch 307 and the interface 303 .

Numbering starts from 0. For a router 30 with a fixed interface or a router 30 with a modular interface, only one number is used in the full name of the interface, and it is numbered according to its physical order in the router 30 . For example, Ethernet0 indicates the first Ethernet interface, and Serial1 indicates the second serial port. For routers that support "online plugging and removal" or change the physical interface configuration, the full name of the interface must contain at least two numbers separated by a slash "/". The first number represents the slot number, and the first number represents the slot number. The 2 digits represent the port number within the interface card. For routers that support "universal interface processor", the interface numbering format is "slot/port adapter/port number". For example, Ethernet4/0/1 is the second Ethernet of the first port adapter on slot 4. network interface.

The types of the local area network interface (LAN interface) 3030 include standard network interfaces such as Ethernet, Fast Ethernet, Gigabit Ethernet, and Ten Gigabit Ethernet. In each network, interfaces of different media standards can be supported, such as RJ45 interface, optical fiber interface, thick coaxial cable interface, etc. The router 30 can be connected to the client computer 40 through the RJ45 interface, so as to realize data communication with the client computer 40 .

The console port Console is usually used to connect the interface with the client 40 using a dedicated connection line when performing basic configuration on the router 30 . As a console port, users or administrators can communicate with the router 30 by using network access equipment to complete the configuration of the router. This port provides an EIA/TIA-232 asynchronous serial interface for configuration on the router 30 .

An EIA/TIA-232 asynchronous serial interface is also provided as an auxiliary port. The difference is that it is often used to connect a modem for remote management of the router.

The power module 306 may include a power supply, power management components, and the like. The power management component is used to manage the charging of the power supply and the power supply from the power supply to other modules.

In other embodiments of the present application, the client 40 and the client 50 may include more or fewer components than those shown, or combine some components, or separate some components, or arrange different components. The illustrated components can be realized in hardware, software or a combination of software and hardware.

The process of assigning an IP address to a client computer by a router provided in the embodiment of the present application is described below:

According to an implementation provided by the embodiment of the present application, after the client 40 accesses the physical interface of the router 30, the router 30 assigns an IP address to the client 40 so that the client 40 can access the Internet via the router 30. For the client 40, it has a MAC address and a Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) client for confirming the location of the client 40 . For the router 30, it has a DHCP server and an IP address pool configured by the DHCP server.

As shown in Figure 4 (a), the client computer 40 is connected to the LAN interface through a cable, and the client computer 40 sends an IP request to the router 30 (requesting the router 30 to assign an IP address), and the IP request carries the MAC address of the client computer 40. The router 30 receives the IP request and parses the IP request to obtain a MAC address. The DHCP server of the router 30 allocates an IP address from the IP pool and sends it to the client 40 based on the MAC address.

In order to further illustrate the flow of the router 30 assigning an IP address to the client 40, the IP address assignment process shown in FIG. 4(a) will be described below in conjunction with FIG. 4(b).

As shown in FIG. 4( b ), at the hardware layer, the client 40 is connected to a LAN interface through a cable, such as the interface 30301 shown in the figure, and the client 40 sends an IP request to the router. The IP request is sent to the switch 307 in the router in the form of data packets. The switch 307 obtains the MAC address of the client 40 after parsing the IP request, and sends the MAC address and other data carried in the IP request to the MAC processing unit in the processor 302 for processing. The MAC processing unit in the processor 302 may include a hardware part (which may be referred to as GMAC hardware) and a software part (which may be referred to as GMAC software, and the corresponding code is run by the controller to realize the function)), which converts the data packet of the router 30 into bitstream. The data processed by the MAC processing unit in the processor 302, such as the MAC address and the rest of the data carried in the IP request, is transferred to the driver module 302 of the software layer, and then passes through the virtual interface corresponding to the LAN interface 30301 and the routing network Module 303 is sent to the DHCP server.

The DHCP server responds to the IP request, and allocates an IP address from the address pool, and sends the data of the LAN interface 30301 to the processor 302 in the form of data packets through the same virtual interface as receiving the IP request. The MAC processing unit in the processor 302 converts the data packet into a bit stream and sends it to the switch 307 . The switch 307 parses out the MAC address of the client 40 from the bit stream, and sends the IP address to the LAN interface 30301 based on the MAC address for the client 40 to access the router 30 through the IP address.

In addition, the router 30 sends the MAC address of the client 40 at the LAN interface 30301 to the interface management module, and the interface management module binds the MAC address and the IP address of the client 40 . The interface management module records the MAC address of the client 40 at the LAN interface 30301. And the number of all clients 40 connected to the interface 303 of the router 30 (that is, the number of MAC addresses) is recorded by the interface management module.

It can be understood that, for the rest of the flow of the client 40 requesting the router 30 to allocate an IP address, reference can be made to FIG. 4( a ) and FIG. 4( b ).

After the router 30 assigns an IP address to the client 40 at the LAN interface 30301, in order for the client 40 to know the total number of clients connected to the router 30 at this time or the MAC address of the client 40 at the LAN interface 30301. The client 40 at the LAN interface 30301 can request the WebUI module of the router 30 to provide the MAC address and the total number of clients connected to the router 30 in a preset way in the WebUI module (the preset way includes picture display, text, etc.) display, etc.) is displayed on the display screen 194 of the client 40.

The process of the client 40 requesting the WebUI module of the router 30 to display information for the relevant interface of the electronic device connected to the router will be described below with reference to FIG. 4( c ). For example, MAC addresses and the total number of clients connected to the router 30 are displayed as interface information.

According to some implementations in the embodiments of the present application, the client 40 at the LAN interface 30301 sends an interface query request to the router 30 . The interface query request carries the MAC address of the client 40 and/or the IP address assigned to it by the router 30 . The interface query request is sent to the WebUI module through the LAN interface 30301, the switch 307, the MAC processing unit included in the processor 302, and the virtual interface corresponding to the LAN interface 30301. The WebUI module obtains the number of MAC addresses recorded in the interface management module from the interface management module. The number of MAC addresses and/or the MAC address information of the client 40 at the LAN interface 30301 is sent to the LAN interface 30301 by the WebUI module. And it is displayed on the display screen 194 of the client 40 at the LAN interface 30301 in a manner preset by the WebUI module (the preset manner includes picture display, text display, etc.).

It is worth noting that the interface query request passes through the MAC processing unit included in the LAN interface 30301, the switch 307, the processor 302, the processing process of the virtual interface corresponding to the LAN interface 30301, and the IP request shown in FIG. 4(b) through the LAN interface. 30301 , the switch 307 , the MAC processing unit included in the processor 302 , and the virtual interface corresponding to the local area network interface 30301 have the same processing procedures, which will not be repeated in this embodiment of the present application.

It can be understood that the remaining clients 40 connected to the router 30 request the WebUI module of the router 30 to provide MAC addresses and the total number of clients connected to the router 30 can be cross-referenced with FIG. 4( c )).

It should be noted that in the embodiment of the present application, except that the client 40 is correspondingly connected to the LAN interface 3030 , the WAN interface 3031 and the router configuration interface 3032 to access the router 30 . The client computer 40 with administrator authority can request the DHCP server of the router 30 to assign IPs for the remaining clients connected to the router 30, or request the WebUI module to provide MAC addresses and connect to the router 30 for the remaining clients connected to the router 30 total number of clients.

Through the above embodiments of the present application, the WebUI module of the router 30 may be able to provide the MAC address and the total number of clients connected to the router 30 for the client 40 connected to the LAN interface 3030 . However, the above information is not enough in some scenarios. For example, when there are too many cables connected to the LAN interface 30301, the LAN interface 30302, and the LAN interface 30303, the cables will be intertwined, and it is difficult for the user to find the corresponding connection between the client 40 and the router 30 for each cable 501. interface. When a user needs to remove a certain client 40, it is necessary to check each cable 501 one by one, which may easily cause other clients 40 to be directly disconnected from the router 30, affecting user experience. The embodiment of the present application further provides a method for providing the location of the physical interface to the client. The following describes the drawings mentioned in other implementations provided by the present application:

Fig. 5 (a) is a kind of client computer that the embodiment of the application forms and the system that router interface forms realizes the structural diagram of IP assignment; The structural diagram of the system implementing interface information query; Figure 5 (c) is a schematic flow diagram of a method for a client to query a router interface provided by the embodiment of the application; Figure 5 (d) is a client provided by the embodiment of the application A diagram showing the router's interfaces.

Still taking the application scenario shown in FIG. 1 as an example, the LAN interface 3030, the WAN interface 3031, and the router configuration interface 3032 in the interface 303 are all mapped with virtual interfaces. The manner in which the LAN interface 3030, the WAN interface 3031, and the router configuration interface 3032 are directly mapped to the virtual interface is to bind each physical interface in the interface 303 to a virtual interface when designing the router. That is, the interface identifier of the corresponding physical interface is marked on the virtual interface, so that the physical interface corresponding to the virtual interface can be found through the interface identifier (such as the number, type, or function parameter of the physical interface, etc.).

The process of assigning an IP address to the client 40 by the router 30 is described below:

At first, as shown in Fig. 5 (a), the structure that the system that the client computer and router interface forms realizes IP allocation includes the client computer 40 at LAN interface 30301, switch 307, processor 302, the virtual network that maps with LAN interface 30301 The interface and the virtual interface mapped with the physical interface of the remaining routers, the DHCP server, the routing network module 303 (TCP/IP protocol) and the interface management module.

It is worth noting that the interface query request passes through the MAC processing unit included in the LAN interface 30301, the switch 307, the processor 302, the processing process of the virtual interface corresponding to the LAN interface 30301, and the IP request shown in FIG. 4(b) through the LAN interface. 30301 , the switch 307 , the MAC processing unit included in the processor 302 , and the virtual interface corresponding to the local area network interface 30301 have the same processing procedures, which will not be repeated in this embodiment of the present application.

With respect to Fig. 5(a), the process of assigning an IP address to the client 40 by the router 30 in Fig. 5(a) is described below:

The client 40 at the LAN interface 30301 sends an IP request to the router 30, and the IP request carries the MAC address of the client 40. The IP request is transmitted to the DHCP server and the interface management module of the router 30 through the LAN interface 30301 , the switch 307 , the MAC processing unit included in the processor 302 and the virtual interface bound to the LAN interface 30301 .

The DHCP server assigns an IP address to the client 40 at the LAN interface 30301. Assigning an IP address specifically includes: the DHCP server responds to the IP request, allocates an IP address from the address pool, and sends the data of the LAN interface 30301 to the processor 302 in the form of a data packet through a virtual interface. The MAC processing unit in the processor 302 converts the data packet into a bit stream and sends it to the switch 307 . The switch 307 parses out the MAC address of the client 40 from the bit stream, and sends the IP address to the LAN interface 30301 based on the MAC address for the client 40 to access the router 30 through the IP address.

It is worth noting that the IP request passes through the MAC processing unit included in the LAN interface 30301, the switch 307, the processor 302, the processing process of the virtual interface corresponding to the LAN interface 30301, and the IP request shown in FIG. 4(b) passes through the LAN interface 30301 , the switch 307 , the MAC processing unit included in the processor 302 , and the virtual interface corresponding to the local area network interface 30301 have the same processing procedures, which will not be repeated in this embodiment of the present application.

The interface management module identifies the virtual interface from which the IP request of the current client 40 is reported, and then the interface management module binds the MAC address carried in the IP request to the virtual interface (as the target virtual interface). Or the interface management module binds the IP address assigned by the DHCP server to the virtual interface. Alternatively, the interface management module binds both the MAC address carried in the IP request and the IP address assigned by the DHCP server to the virtual interface. Thus, the virtual interface parameters of the virtual interface include, but are not limited to, the physical interface information of the target physical interface bound to the target virtual interface, the MAC address carried in the IP request, and the IP address assigned by the DHCP server.

Further, when the client 40 is removed from the interface of the router 30, in order to avoid occupation of the virtual interface of the router 30. In the embodiment of the present application, when the client 40 is removed from the interface of the router 30 . The router erases the binding information between the IP address and the target virtual interface, or the router erases the binding information between the client's MAC address and the target virtual interface, or the router erases the client's MAC address and IP address and the target virtual interface binding information to avoid occupying the virtual interface resources of the router. Further, the IP address and MAC address of the client 40 may also be erased by the router.

The interface query request carries the MAC address of the client 40 and/or the IP address assigned to it by the router 30 . The interface query request is sent to the WebUI module through the LAN interface 30301, the switch 307, the MAC processing unit included in the processor 302, and the virtual interface corresponding to the LAN interface 30301. The WebUI module obtains the physical interface information of the router 30 corresponding to the IP address in the interface management module from the interface management module. The physical interface information is sent to the LAN interface 30301 by the WebUI module. And it is displayed on the display screen 194 of the client 40 at the LAN interface 30301 in a manner preset by the WebUI module (the preset manner includes picture display, text display, etc.).

Referring to FIG. 5( b ), the process of querying the interface information of the LAN interface 30301 connected to the client 40 by the router 30 in FIG. 5( b ) will be described below in conjunction with FIG. 5( c ).

As shown in Figure 5(c), the methods for the client to query the router interface include:

Step S30: the client 40 (as the target electronic device) at the LAN interface 30301 sends an interface query request to the router 30 .

The interface query request carries the MAC address of the client 40 at the LAN interface 30301 and/or the IP address assigned to it by the router 30 . Clients or other devices connected to the LAN interface 30302 and the LAN interface 30303 or other interfaces can serve as the rest of the electronic equipment. It should be noted that a client computer or other type of electronic device with administrator authority can be used as the first electronic device in the embodiment of the present application to inquire about other electronic devices connected to the router 30 or the client computer 40 at the LAN interface 30301 physical interface information.

When the client 40 at the LAN interface 30301 sends an interface query request to the router 30, the interface query request is transmitted to the router through the MAC processing unit in the LAN interface 30301, the switch 307, the processor 302 and the virtual interface bound to the LAN interface 30301 30 WebUI modules.

It is worth noting that the interface query request passes through the MAC processing unit included in the LAN interface 30301, the switch 307, the processor 302, the processing process of the virtual interface corresponding to the LAN interface 30301, and the IP request shown in FIG. 4(b) through the LAN interface. 30301 , the switch 307 , the MAC processing unit included in the processor 302 , and the virtual interface corresponding to the local area network interface 30301 have the same processing procedures, which will not be repeated in this embodiment of the present application.

Step S31: The router 30 determines the target virtual interface associated with the IP address of the client 40 at the LAN interface 30301 according to the interface query request. Specifically, the interface management module obtains the IP address and MAC address of the client 40 at the LAN interface 30301 in the interface query request. The WebUI module of the router 30 requests the interface management module to query the virtual interface bound to the IP address and/or MAC address of the client 40 (as the target virtual interface).

Step S32: The router 30 determines the target physical interface corresponding to the target virtual interface according to the preset mapping relationship between the virtual interface and the physical interface. The preset mapping relationship between a virtual interface and a physical interface means that a virtual interface is correspondingly configured for each physical interface. The virtual interface parameter of the virtual interface includes the interface identifier of the physical interface, and the virtual interface and the physical interface are mapped and configured in a one-to-one correspondence manner. The configuration file recording the mapping relationship between the virtual interface and the physical interface corresponding to the virtual interface is stored in the memory of the router. The process of determining the target physical interface corresponding to the target virtual interface is specifically: the interface management module of the router determines the target physical interface corresponding to the target virtual interface according to the interface identifier of the target physical interface preset in the target virtual interface.

Step S33: the router 30 searches for the physical interface information of the target physical interface, and sends the target physical interface of the target physical interface to the client 40. Specifically: the WebUI module of the router 30 provides the physical interface information of the target physical interface to the client 40 at the LAN interface 30301 .

The client 40 at the LAN interface 30301 can display the physical interface information in the form of a picture on the display screen 405 , and can also play the physical interface information through the client 40 . Thereby, it is convenient for the user to find the LAN interface 30301.

The physical interface information includes the interface identification of the LAN interface 30301 (such as interface number, model, and function parameters, etc.), a picture of the location of the LAN interface 30301 on the router 30 (interface schematic diagram), and the like.

As shown in FIG. 5( d ), the client 40 displays the basic information (power information 101B and time 101C) and physical interface information of the client 40 on the display screen 405 . The physical interface information displays the specific location of the LAN interface 30301 on the router 30, the serial number of the LAN interface (such as 30301), the number of clients connected to the router (such as 3), and the MAC address of the client computer at the LAN interface in the form of a picture. (such as 44-45-53-54-00-01), the name of the client connected to the LAN interface 30301 (such as Bob) and other information. In the embodiment of the present application, the specific location of the LAN interface 30301 on the router 30 is displayed in the form of a picture, specifically referring to the rest of the physical interfaces on the router 30, and the LAN interface 30301 is displayed in a heavy color and the serial number 30301 of the LAN interface is displayed at the same time. It is worth noting that the physical display information can be prompted on the client 40 or in other ways, such as voice broadcast, text description, etc., which are not limited in this embodiment of the present application. The information displayed by the client computer 40 in the form of pictures on the display screen 405 is not limited to the example shown in FIG. 5( d ).

The content contained in the physical interface information is not limited in this embodiment of the application.

Through the above implementation manners of the present application, it can be seen that the router can provide the client connected to the target physical interface of the router with the location of the target physical interface on the router. Even if the cables of multiple client computers connected to the router interface are intertwined, the user can quickly find the target physical interface to which the client computer is connected according to the position of the target physical interface indicated by the router on the router. When the user needs to remove a certain client computer, the corresponding search is directly performed on the router based on the position of the indicated target physical interface, and the operation is performed on the interface connected to the client computer. It will not cause other clients to be disconnected from the router, which improves the user experience.

The interface management module identifies the virtual interface from which the IP request of the current electronic device is reported, and then the interface management module binds the MAC address carried in the IP request to the virtual interface (as the target virtual interface). Or the interface management module binds the IP address assigned by the DHCP server to the virtual interface. Alternatively, the interface management module binds both the MAC address carried in the IP request and the IP address assigned by the DHCP server to the virtual interface. Thus, the virtual interface parameters of the virtual interface include, but are not limited to, the physical interface information of the target physical interface bound to the target virtual interface, the MAC address carried in the IP request, and the IP address assigned by the DHCP server.

Further, the interface query request carries the MAC address of the target electronic device connected to the target physical interface and/or the IP address assigned to it by the router. It should be noted that the electronic device with administrator authority can serve as the first electronic device in the embodiment of the present application, and query the physical interface information of other electronic devices connected to the router.

Specifically, the interface management module obtains the IP address and MAC address of the target electronic device in the interface query request. The WebUI module of the router requests the interface management module to query the virtual interface bound to the IP address and/or MAC address of the target electronic device (as the target virtual interface).

The router determines the target physical interface corresponding to the target virtual interface according to the preset mapping relationship between the virtual interface and the physical interface.
