Problems solved by technology
[0005] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide an identification method, device and storage medium for an IP address allocation port, so as to overcome the problem that the routing equipment in the prior art only has a message forwarding function and cannot identify the allocation port. The specific downlink port of the IP address or the specific device connected to each downlink port. When there is a problem with packet forwarding of a certain device, it is necessary to traverse all the downlink ports of the routing device to determine the specific downlink port connected to the device. The operation is cumbersome. defect

Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] In order to solve the problem that the existing routing device only has the function of packet forwarding, but cannot identify the specific downlink port assigned the IP address or the specific device connected to each downlink port, when there is a problem with the packet forwarding of a certain device, it is necessary to traverse the All downlink ports are used to determine the specific downlink port that the device is connected to, and the operation is cumbersome. The invention provides a method for identifying an IP address allocation port.

The present invention provides an identification method, device and storage medium for an IP address assignment port, the method comprising: receiving an IP message sent by an Internet of Things terminal, and parsing out the MAC address of the Internet of Things terminal from the IP message address and IP address; according to the analyzed MAC address and IP address, identify the port corresponding to the IP address from the correspondence between each port obtained in advance and the MAC address of the connected IoT terminal. The present invention analyzes the MAC address and IP address of the Internet of Things terminal from the received IP message, and compares the resolved MAC address and IP address with the MAC address of each port obtained in advance and the Internet of Things terminal connected to it. Match the corresponding relationship of each port to determine the IP address assigned to each port and the connected IoT terminal, which facilitates the maintenance and replacement of the IoT terminal.
Description
technical field [0001] The present invention relates to the technical field of network communication, in particular to an identification method, device and storage medium of an IP address allocation port. Background technique [0002] Existing routing equipment such as figure 2 As shown, it is composed of a main control CPU and a switch chip. The main control CPU provides a router protocol and supports the DHCP server function. The switch chip has an uplink port P8 and four downlink ports P0~P3. The uplink port P8 is connected to the CPU network port eth0. The four downlink ports P0-P3 can be directly connected to the downlink device, and the message sent by the downlink device is forwarded to the CPU network port eth0 through the switch chip, and the CPU protocol stack processes the message accordingly. [0003] However, the existing routing device only has a packet forwarding function, but cannot identify which downlink port the allocated IP address is on or the specific ...
