Embodiment Construction

[0074] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0075] The stacking implementation method provided by the embodiment of the present invention is used to construct such as figure 1 The stacking system shown includes multiple switches in the stacking system, one of which is configured or designated as the master device, and the remaining switches are used as non-master devices. Since the stacking system adopts a linear (English: linear) connection Therefore, each non-master device has no more than two ports for creating a stack system. The ports can be physical ports or logical link aggregation (English: link aggregation) ports. figure 1 The first device is connected to the second port eth2 on the second device through the first port eth1, and the second device is connected to the fourth port eth4 on the third device through the third port eth3. The embodiment of the...

Abstract

The embodiment of the invention provides a stacking realization method, which comprises the following steps: first equipment broadcasts a stacking enabled message via a first port, wherein the stacking enabled message carries information for other pieces of equipment to establish the stacking relationship with the first equipment, the first equipment is the main equipment of a stacking system, the first port for broadcasting the stacking enabled message is used as the stacking port of the first equipment, and the first port is positioned on the first equipment; the first equipment receives a first stacking confirmation message sent by second piece of equipment, wherein the first stacking confirmation message carries the MAC (media access control) address of the second equipment and the information of a stacking port which takes the second port as the second equipment and faces to the first equipment, and the second port is positioned on the second equipment; and the first equipment switches the first port to a stacking port from a common service port to record the MAC address of the second equipment and the topological relationship of the first port and the second port. According to the above embodiment, switches can carry out auto-negotiation to establish a stacking system without manual configuration.

Description

technical field [0001] The present invention relates to the communication field, in particular to a stacking realization method and a stackable device. Background technique [0002] Stacking refers to combining more than one switch to work together to provide as many ports as possible in a limited space. Multiple switches are stacked to form a stacking system. For the connected devices outside the stacking system, several components of the stacking system are formed. A switch is a switch. One of the multiple switches that make up the stack system acts as the master device and is responsible for the management of the entire stack system. [0003] Generally, there are several ways to realize the stacking system. For example, the switch is provided with a dedicated stacking port, and the stacking port is only used for information transmission in the stacking system, such as consistency information between switches and real-time synchronization data. It cannot be used as a com...
