Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Before describing the embodiments of the present invention, the idea of ​​the technical solution provided by the present invention is briefly introduced:

[0029] For the driver, the MAC address that needs to be reported to the platform and the MAC address issued by the receiving platform are two different threads, and the processing procedures of the two threads are different. The same MAC is reported from the driver to the platform The t...

Abstract

The invention provides a MAC address synchronization method and device. Wherein, the method includes: under the condition that the first hardware reports the first media access control (MAC) address to the platform, after successfully storing the first MAC address in the preset cache, and reporting the first MAC address to the platform; When the address is delivered to the second hardware, when the second MAC address is not found in the preset cache, the second MAC address is delivered to the second hardware. Through the present invention, the software and hardware out-of-synchronization problems can be corrected in time, and the traffic forwarding problem can be solved to the greatest extent, thereby ensuring the reliability of the network.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for synchronizing MAC addresses. Background technique [0002] The MAC (Media Access Control, Media Access Control) address is the hardware identifier of the network device, and the switch forwards the message according to the MAC address. There is a hardware MAC address table stored on the hardware of the switch. The hardware MAC address table is the basis for the switch to realize fast packet forwarding. When the switch receives a data frame, it decides whether to filter the data frame or forward it to the corresponding port on the switch. On top of the hardware MAC address table, each switch maintains a software MAC address table through which MAC addresses can be added, deleted and synchronized. MAC address management is one of the most basic functions of a switch, and keeping the hardware MAC address table consistent with the software MAC address table is the ...
