Problems solved by technology

However, if STA1 needs to receive a DHCP message, STA2 and STA3 do not need to receive a DHCP message. Even if there is DHCP snooping in the current mechanism, the multicast message will inevitably be sent to all antennas, because the DHCP snooping implemented under normal circumstances It is not possible to "snooping" (listen) to the antenna

Abstract

The embodiment of the invention discloses a sending method of a DHCP report and a device. An AP establishes a snooping table item under multiple users and multiple-input multiple output conditions, wherein the snooping table item comprises a mapping relation between an antenna ID, a user terminal ID and a user terminal MAC address related to the DHCP. When the AP receives a DHCP report related to a user terminal, the AP only emits the DHCP report on the antenna corresponding to the user terminal according to the snooping table item. According to the invention, 'snooping' of an access point where the DHCP snooping function is achieved to the antenna is achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of wireless local area network processing, and in particular to a method and device for sending a DHCP message. Background technique [0002] With the development of network technology, more and more attention is paid to network security, especially in some important departments, such as the internal development network of the formula, the internal network of government agencies, bank networks and military networks, etc. How to improve network security has become a a necessary subject. [0003] Dynamic Host Configuration Protocol (DHCP) is a local area network network protocol, using User Datagram Protocol (User Datagram Protocol, UDP) to work, there are two main purposes: to the internal network or network service provider to automatically assign IP Address, given to users or internal network administrators as a means of centrally managing all computers. [0004] DHCP is usually ...
