Method and system for selecting link aggregation root port on stacking device

Abstract

The invention discloses a method and system for selecting a link aggregation root port on a stacking device, which belongs to the technical field of switches and includes the following steps: A. After the main control device of the stacking system generates a management control message, determine the outgoing interface as a link Aggregation group; B. In the link aggregation group, select a member port with the smallest distance from the master control device as the sending port of the management control message. The beneficial effects of the present invention are as follows: through this technical scheme, when the link aggregation of the stacking system sends a message, it will preferentially select the port on the master control device to directly send, if there is no member port on the master control device, it will also preferentially select The member port closest to the master control device is used for sending, which can save the bandwidth of the management control channel between stacking system devices and the CPU resource consumption of related devices to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a method and system for selecting a link aggregation root port on a stacking device. Background technique [0002] In a switch network, link aggregation technology aggregates multiple physical ports into an aggregation group to increase link bandwidth, mutual backup, and load balancing. [0003] With the development of technology, a stacking technology of switches appears. Through this technology, multiple physical devices are aggregated into one logical device, which simplifies device management and improves device reliability. [0004] In the stacking system, the link aggregation technology is more widely used, and multiple ports on different physical devices are aggregated into one aggregation group. This networking method can also solve some single-machine failures, and the reliability can be further improved by this method. [0005] However, in a stacking system, managemen...

Problems solved by technology

Usually, the main control device of the stack system will perform a large amount of protocol interaction with other devices. This kind of management data will be relatively large, which will occupy a large amount of stack system management control channel bandwidth and waste a lot of CPU resources. When the selected sending port is located The farther the distance between the member device and the main control device is, the more bandwidth of the management control channel is wasted. Especially in the case of chain stacking, the main control device is at the head of the chain, and the selected sending port is at the end of the chain, so the waste is the most serious.

[0007] With the application of stacking technology more and more widely, this method wastes more and more management control channel bandwidth and CPU resources, which will lead to the instability of the stack system and the excessive occupation of management control channels, which will cause more management channel processing overhead.
