Switch stacking method and system

Abstract

The invention relates to a switch stacking method and system, and the method comprises the following steps: switches send probing messages to each other, and find nearby stacked group members through probing; the switches send negotiation messages mutually, and a master switch and a slave switch are selected according to a set selection rule; the slave switch reports the equipment information and the topological structure to the master switch; the management end issues an instruction to the whole stacked switch group through the main switch for configuration or query; by means of the method, mixed stacking of switches of different models of the same manufacturer is supported, the limitation that the switches of the same model must be eliminated, an intelligent election scheme is provided, the switches can be freely switched between the stacking mode and the common single-machine mode, no limitation exists, a special stacking module and a special stacking cable are not needed, and the switching efficiency is improved. A common high-speed port and a connecting line can meet the requirement of a stacking mode, the transmission efficiency is higher due to the two stacking ports, and annular redundancy can be achieved.

Description

technical field [0001] The present invention relates to the technical field of switch stacking, and more specifically, to a switch stacking method and system. Background technique [0002] Switch stacking technology refers to combining more than one switch to work together to increase port density and network bandwidth in a limited space. Multiple stacked switches can be regarded as one device, and the master device manages the remaining multiple slave devices. The stacking technology has the advantages of high reliability, high scalability, and simplified configuration and network management. [0003] Stacking technology is a non-standardized technology and a specific implementation of a concept. There is no unified standard and protocol, so each manufacturer has its own implementation methods and characteristics. Some of the existing defects are as follows: [0004] 1. Mixed stacking is not supported, even devices of different models from the same manufacturer cannot be s...
