Abstract

The embodiment of the invention provides a message synchronization method and a message synchronization device, relates to the field of communication and can solve a problem that different board cards of switching equipment in the prior art cannot acquire the same message so as to perform MAC (Media Access Control) address learning. The message synchronization method comprises the steps of when a message is received and the message is determined to a unicast message, finding a destination MAC address of the message and a source MAC address of the message; S2, when the destination MAC address of the message is successfully found and the source MAC address of the message is unsuccessfully found, acquiring a destination interface board ID, wherein the destination interface board ID is an interface board ID corresponding to the destination MAC address of the message; S3, sending an ACL (Access Control List) item, wherein the ACL item comprises other interface board IDs except for the destination interface board ID on the switch equipment; and S4, copying the message to interface boards corresponding to the interface board IDs in the ACL table item. The message synchronization method and the message synchronization device are used for synchronizing messages.

Description

technical field [0001] The invention relates to the communication field, in particular to a message synchronization method and a message synchronization device. Background technique [0002] In recent years, with the rapid development of network technology, the number of network nodes in the network has increased rapidly, and the structure of the network has become more and more complex. Consequently, the number of switch devices that provide information exchange services for network nodes is gradually increasing. Usually, when the switch device performs Layer 2 forwarding, it needs to extract the destination Media Access Control (English full name: Media Access Control, English abbreviation: MAC) address from the forwarded data packet, and forward the Post to get the corresponding port. In order to ensure the validity of the MAC address table, the switch device also learns the source MAC address according to the received message, so as to update the MAC address table acco...
