DETAILED DESCRIPTION
[0017] Embodiments of the present application will be described in more detail with reference to the drawings. Although the embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.
[0018] It should be understood that although the terms "first", "second", "third", etc. are used to describe various information in the present application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the present application. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified and limited.
[0019] Unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected or integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0020] Most router products implement the function of automatically identifying the online port, and the implementation scheme is to try to obtain IP on the corresponding network card by dhcp, and the network card that obtains IP is set as the network wan, that is, the online port. But this way needs to correspond the physical network port on the router with the network card one by one, needs more network ports, thereby increasing the maintenance cost.
[0021] To solve the above problems, the embodiment of the application provides a method, device, electronic equipment and storage medium for automatically identifying an online port of a router, which can reduce the number of physical network ports, improve the effective utilization rate of the physical network ports, and reduce the maintenance cost.
[0022] The technical solutions of the embodiments of the application are described in detail below with reference to the drawings.
[0023] Figure 1 FIG. 1 is a flowchart of a method for automatically identifying an online port of a router according to an embodiment of the application.
[0024] Referring to Figure 1 A method for automatically identifying an online port of a router comprises the following steps. Step S101: mapping a network port with a switch port, and outputting a plurality of virtual network cards.
[0025] It should be noted that the switch is integrated in the router, the switch has a plurality of ports, and the router backend maps a plurality of physical network ports with the switch ports. Further, after the mapping is completed, the router backend generates a plurality of virtual network cards according to the number of the switch ports.
[0026] Step S102: performing a primary division on the switch ports, and outputting a LAN virtual network card and a WAN virtual network card.
[0027] It should be noted that the switch divides all the ports thereof into VLAN1 through VLAN division. The router backend adjusts the number of the virtual network cards to two according to VLAN1, one of which is a LAN virtual network card and the other of which is a WAN virtual network card. The WAN virtual network card does not have a corresponding switch port, in other words, all the ports in VLAN1 currently correspond to the LAN virtual network card.
[0028] Step S103: collecting network cable insertion information, identifying the network cable insertion information, and outputting port information.
[0029] It should be noted that when a network cable is inserted into the router, the router backend actively sends a message about the inserted network cable to a monitoring process of the router to start network port identification, so as to obtain which online physical network port of the router is, that is, the above-mentioned port information.
[0030] Step S104: performing a secondary division on the switch ports according to the port information, outputting a WAN port and a LAN port, binding the WAN port with the WAN virtual network card, and binding the LAN port with the LAN virtual network card.
[0031] It should be noted that the switch will perform secondary division on the ports in VLAN1, and according to the port information, it is obtained which port is the WAN port for online, and then the WAN port is bound with the WAN virtual network card, and the LAN port is bound with the LAN virtual network card.
[0032] In summary, compared with the traditional one-to-one designation of the virtual network card corresponding to the network port, if the network is to be configured, multiple network cards need to be operated simultaneously. However, the present application directly abstracts the virtual network card into two LAN virtual network cards and WAN virtual network cards, and directly operates at the switch level, which can automatically identify the WAN port, that is, the same network port on the router can be a LAN port or a WAN port, thereby reducing the number of network ports.
[0033] Figure 2 For Figure 1 In a more detailed embodiment, a method for automatically identifying the network port of a router comprises: Step S201, mapping the network port with the switch port, and outputting a plurality of virtual network cards.
[0034] This step can refer to step S101, which will not be described here.
[0035] Step S202, performing primary division on the switch port, and outputting LAN virtual network cards and WAN virtual network cards.
[0036] This step can refer to step S102, which will not be described here.
[0037] Step S203, collecting the network cable insertion information, obtaining the upper-level route IP address, and obtaining the upper-level route MAC address through the router ARP table according to the upper-level route IP address. Obtain the switch MAC address table, and obtain the port information according to the upper-level route MAC address.
[0038] It's important to note that the upstream router can be an optical modem or a gateway. The router's ARP table can be used to obtain the upstream router's MAC address from its IP address. Next, the switch's MAC address table is accessed, and the port number is determined based on the upstream router's MAC address. Specifically, when a computer on the network (e.g., PC A) needs to communicate with a device at another IP address, it follows these steps to determine the target: PC A checks if the target IP address is on the same network segment as itself. If not, it sends the data packet to the pre-configured default gateway. Although PC A knows the IP address to be sent to the router, within the local area network, the data ultimately needs to be encapsulated into an Ethernet frame for transmission, and the frame header requires the target's MAC address. At this point, PC A sends an ARP request packet. This packet is essentially a broadcast query, roughly stating: "Device with IP address XXX.XXX.XXX.XXX, what is your MAC address?" The destination MAC address of this ARP request frame is FF-FF-FF-FF-FF-FF, i.e., the broadcast address. When this broadcast frame arrives at the switch, the switch performs a flooding operation, forwarding it from all ports except the receiving port. The upstream router receives this ARP request from the port it's connected to on the switch. Recognizing that its IP address has been queried, it sends an ARP reply packet containing its own MAC address. This reply is sent directly to PC A. When the router's ARP reply frame enters the switch through a port, the switch checks the frame's source MAC address and immediately learns that a device with that MAC address is connected to this port. The switch then creates or updates the mapping between the router's MAC address and the corresponding port in its MAC address table.
[0039] Step S204: Based on the port information, perform secondary partitioning of the switch ports to output WAN and LAN ports, bind the WAN port to the WAN virtual network card, and bind the LAN port to the LAN virtual network card.
[0040] This step can be referred to as step S104, and will not be repeated here.
[0041] Step S205: Connect the LAN port to the bridge or connect the WAN port to the bridge.
[0042] It should be noted that connecting the LAN or WAN port to a bridge allows the router to communicate with other electronic devices.
[0043] Furthermore, in another embodiment, a method for automatically identifying a router's internet access port further includes: Acquire and store information about each virtual network interface card and switch port; Configure mapping rules to automatically match each virtual network card with the switch port based on the information of each virtual network card and the switch port information, and output the second port unit.
[0044] It should be noted that a virtual network interface card (NIC) information collection module is deployed at the back end of the router to collect key information for each virtual NIC, including but not limited to the virtual NIC identifier, virtual machine identifier, IP address, MAC address, and virtual network to which the virtual NIC belongs. The collected virtual NIC information is stored in a pre-defined network resource database, which may be a relational or non-relational database. An association index is established between the virtual NIC identifier and other information to facilitate subsequent queries and retrieval. By comprehensively collecting key information from the virtual NICs, accurate foundational data is provided for subsequent mapping and matching, avoiding mapping errors due to missing information. Establishing an association index improves information retrieval efficiency and ensures a rapid mapping process. Furthermore, a switch port information collection module is deployed at the back end of the router. This module establishes a communication connection with the physical switch via a network management protocol. It collects key information for each switch port, including but not limited to the switch identifier, port identifier, VLAN ID, port speed, port duplex mode, current port status, MAC addresses of connected devices, and physical server connection information. The collected switch port information is stored in the aforementioned network resource database, separated from the virtual network interface card (NIC) information in a separate table. An index is established linking switch identifiers, port identifiers, and other information, while also establishing a relationship between switch ports and physical servers. This allows for comprehensive information on switch ports, clarifying the attributes and connection status of each port, providing a basis for matching with virtual NICs. Information is collected through multiple protocols to ensure its comprehensiveness and accuracy, while the established relationships facilitate precise matching later.
[0045] It should also be noted that the basic mapping rules include, but are not limited to: VLAN-based matching rules: matching the VLAN ID of the virtual network interface card (NIC) with the VLAN ID of the switch port, establishing an initial association between virtual NICs with the same VLAN ID and the switch port; MAC address-based matching rules: if the virtual machine corresponding to the NIC is already connected to the switch port through a physical server, the MAC address of the connected devices on the switch port is queried and matched with the MAC address of the virtual NIC to establish an association; physical server-based association rules: based on the physical server to which the NIC belongs, the switch port connected to that physical server is found, establishing an association between the virtual NIC and the corresponding switch port. When multiple basic mapping rules are triggered simultaneously, the final mapping relationship is determined according to a preset priority. For example, the priority from high to low is: MAC address matching rules > physical server association rules > VLAN matching rules. Administrators can adjust the priority order according to the actual network environment. In this way, by flexibly configuring multiple mapping rules, the mapping needs of different network scenarios can be met; setting priority rules can solve rule conflict problems and ensure the uniqueness and accuracy of the mapping relationship; dynamic rule adjustment is supported, improving the adaptability and flexibility of the method.
[0046] Specifically, according to the configured mapping rule priority, the virtual network interface card (NIC) information and switch port information are matched sequentially: First, the MAC address matching rule is applied: the MAC address of the virtual NIC is queried, and the switch port information is searched for ports with the same MAC address as the connected devices. If a unique matching port is found, the mapping relationship is initially determined; if multiple matching ports are found or no matching port is found, the process proceeds to the next priority rule matching. Second, the physical server association rule is applied: the physical server information to which the virtual NIC belongs is obtained, and the switch port information is searched for ports connected to that physical server. If a unique matching port is found, the mapping relationship is determined; if multiple ports are connected to the same physical server, the VLAN ID of the virtual NIC is used for further filtering to find ports with the same VLAN ID; if no match is found, the process proceeds to the next priority rule. Finally, the VLAN matching rule is applied: the switch port with the same VLAN ID as the virtual NIC is searched; if multiple such ports are found, the port is filtered based on its operating status and port speed to determine the final mapped port; if no matching port is found, a matching failure log is generated, and an alarm is triggered. In this way, the mapping efficiency is improved by replacing manual configuration through an automated matching process; the mapping relationship is ensured by matching step by step according to priority rules; and the mapping relationship is stored and indexed to facilitate subsequent querying, management and monitoring.
