Problems solved by technology

Daisy-chain stacking is a simplified stacking technology that can provide excellent forwarding performance and convenient management features when there are fewer stacking levels, such as expansion ports between boards in a communication equipment chassis. However, the existing daisy-chain stacking The port is fixed and cannot be used as an ordinary cascade port
In stack management, master-slave devices are distinguished, which has certain restrictions on applications. For example, when

Example Embodiment

[0043] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0044] In view of the fact that the stacking port between chips in the prior art cannot be automatically switched to work in non-stacking mode, it cannot realize the common cascading application between chips through the stacking port, and it does not provide stacking link reliability detection and forwarding table synchronization processing after switch stacking. , And stacking equipment also needs to distinguish between master and slave issues, providing a method and device for switching equipment stacking, by pre-initializing the preset ports of the switching equipment to non-stacking mode, and then after the switching equipment is powered on, through the preset report The interaction of the text realizes the dynamic switching of the s...

Abstract

The present invention provides a switch equipment stacking method and device. The method is applied to switch equipment. The method comprises a step of obtaining the power-on information of first switch equipment which is in the connection system formed by the pre-stacking of multiple switch equipment and has a default port whose initialization is a non-stack mode, a step of obtaining the information of power-on and sending an exchange preset message to the switch equipment which is connected to the first switch equipment, a step of receiving the response message of stack approval returned by the switch equipment which is connected to the first switch equipment according to the exchange preset message, converting the preset port of the first switch equipment into a stack mode from the non-stack mode so as to realize the stack message exchange of the first switch equipment and the switch equipment which is connected to the first switch equipment, and a step of detecting the exchange condition of the first switch equipment and the preset message of the switch equipment which is connected to the first switch equipment, and maintaining the preset port in a stacked mode.

Description

technical field [0001] The invention relates to Ethernet switching technology, in particular to a method and device for stacking switching equipment. Background technique [0002] Stacking is a technology widely used to expand ports on Ethernet switches at present, and it is a non-standardized technology. Currently there are two popular stacking modes: star mode and daisy chain mode. [0003] Star stacking technology, for switches, needs to provide an independent or integrated high-speed switching center (stacking center), all stacking hosts are uplinked to a unified stacking port through a dedicated (or general-purpose high-speed port) high-speed stacking port Center, the stacking center is generally a hardware switching unit based on a dedicated ASIC (Application Specific Integrated Circuit). According to its switching capacity, the bandwidth is generally between 10-32G, and its ASIC switching capacity limits the number of stacked layers. The star stacking mode is suitab...
