Embodiment Construction

[0048] The precondition that method described in the present invention realizes is:

[0049] 1. Specify a unique device ID (device ID) for each stack member;

[0050] 2. Define three states for stack members, IamMaster, SeekingMaster and FoundMaster respectively represent: master device, waiting to join the stack system and joined the stack system.

[0051]3. The roles of stack members are divided into master device, slave device and backup device. The Master (master device) refers to the device that acts as a controller and manager in the stack system; Serve as controlled and managed equipment in the stacking system; said Backup (standby equipment) refers to the equipment that acts as the backup equipment of the main equipment in the stacking system, and this equipment is in the status of Slave when there is a main equipment in the stacking system Running, when the master device in the stack system fails or is missing, it will automatically switch to Master.

[0052] In a s...

Abstract

The present invention discloses a Ethernet switch stacking system management method, which comprises that stacking members are initialized for the stacking system waiting for joining in, the owner information of the stacking member is empty, the main device is confirmed, and a device configuration table is arranged; the stacking member waiting for joining in the stacking system sends out the joining in request message to the outside for joining in the stacking system; the stacking member receives the message judges whether allowing the stacking system waiting for joining in the stacking system to join in the stacking system or not, if the joining in is allowed, a joining allowance message is sent; and the stacking member receives the message judges whether allowing the stacking system of which the state is waiting for joining in the stacking system to join in the stacking system or not, if the joining in is allowed, the state is moved to be the state of being joined in the stacking system. The present invention ensures that the stacking members join in the stacking system gradually, thus the initiation and the forwarding number of the topology management message between the stacking members are reduced, the CPU and bandwidth resource are saved, and the message loop and the broadcasting storm are effectively prevented.

Description

technical field [0001] The invention relates to the Ethernet switch stacking technology in the field of data communication, in particular to a method for managing the Ethernet switch stacking system. Background technique [0002] With the rapid development of information technology and the rapid expansion of network scale, it is often difficult to accurately predict the future network scale in the current network planning. When the number of planned switch interfaces is not enough to meet the needs of network applications, it is best The number of interfaces of the switch can be increased without changing the original network planning topology, and at the same time, the burden of the network management is not increased. At this time, the stacking technology of switches emerges as the times require, which can just meet the above requirements. [0003] The stacking of switches refers to connecting multiple stackable switches through stacking interfaces with cables, so as to r...
