Abstract

The invention discloses a method and a device for preventing switch ports from MAC address transfer, which relate to the access network security technology of an Ethernet switch and aim to solve the problem that MAC address transfer prevention cannot be effectively realized on an Ethernet switch chip of the switch in the prior art. The method comprises the following steps: setting the MAC address transfer prevention authority of each port of the switch chip in the switch; disenabling automatic MAC address leaning functions of all the ports; modifying a forwarding strategy of unknown source MAC address packets of the ports to indicate the unknown MAC address packets are not to be forwarded, and starting the MAC address learning and ageing interruption of the ports; when new source MAC address messages are received, determining a learning strategy according to the configuration of the ports and database record information; and if MAC address ageing information is received, updating database record. The switch comprises the switch chip, a priority setting module, a database module and a management CPU.

Description

technical field [0001] The invention relates to an access network security technology of an Ethernet switch, in particular to a method and a device for realizing anti-migration of a MAC address of a switch port. Background technique [0002] The technology of broadband access network is developing rapidly, and its application is becoming more and more extensive. However, security issues have become more and more concerned issues along with its development. In the access network environment, users, access devices, and networks face various threats, especially threats from the user side. [0003] The rapid development of broadband access networks has doubled the number of broadband users, but it has also greatly increased the possibility of network security attacks. Especially after the introduction of Ethernet technology and IP technology, the problem of access network security has become increasingly prominent. Because Ethernet is a shared network, its advantages and disad...
