Equipment topology structure forming method in stack system

Abstract

The disclosed forming method for topological structure of stack system comprises: arranging two or more exchange units for the system, sending topological message with label item from one unit to another to determine the unique feature of exchange unit, selecting a main unit to send message to other units, beginning topological convergence. This invention improves stack system reliability.

Description

technical field [0001] The invention relates to network technology, in particular to a method for forming a topological structure of stacking system equipment. Background technique [0002] With the popularization of broadband applications and the growth of enterprise information application requirements, the overall speed of the network continues to increase, and the demand for high-throughput data exchange and various intelligent applications is also increasing. In order to make the data switching device meet the port quantity requirements of the large-scale network, it is generally solved by stacking the devices in a large-scale network. Users can connect multiple switching unit devices (UNIT, each UNIT has "UP" and "DOWN" stacking ports at the same time) through the stacking ports to form a ring or chain joint device (Fabric). [0003] In a stacking system, each UNIT needs to have a unique identifier, the source of which is the MAC (Media Access Control, Media Access Co...

Problems solved by technology

However, since the MAC addresses of UNIT 1 and UNIT 4 are exactly the same, the Ad packet sent by UNIT1 is the same as the Ad packet sent by UNIT 4, which will make UNIT4 mistakenly believe that it has received the Ad packet sent by itself, and then think that the topology is a ring;
