Abstract

The invention discloses an MAC address learning method, a gateway device and a storage medium. The method comprises the steps of enabling a CPU to determine the MAC learning number according to learning requirements; after a first message is received, detecting whether a first source MAC address in the first message needs to be learned or not according to a preset MAC forwarding table; if the first source MAC address needs to be learned, detecting whether the number of messages in a preset MAC learning message queue reaches the MAC learning number or not; if the MAC learning quantity is not reached, generating a first MAC learning message containing the first source MAC address, and adding the first MAC learning message into the MAC learning message queue; and carrying out source MAC address learning on the MAC learning messages in the MAC learning message queue, so that MAC address learning is carried out by utilizing a CPU, the learning is more flexible, and the reliability is higher.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method for learning a MAC address, a gateway device and a storage medium. Background technique [0002] With the rapid development of computers and their interconnection technologies, Ethernet has become the short-distance layer-2 computer network with the highest penetration rate so far. The core component of Ethernet is the Ethernet switch. Switches work on the second layer of the OSI reference model, the data link layer. When the switch receives a frame, it first checks whether there is a source MAC address in the frame in the MAC address table it maintains. If there is no source MAC address, put the source MAC address, VLAN, and port into this table; if there is a source MAC address, look up the destination MAC address in this table, and if there is a match, proceed according to the port number in the table entry Forward; if not, forward to all other ...
