网络环路防止技术研究

Research on Prevention Technology of Network Loop

网络环路具有隐蔽性高、故障排查难度大的特点,其出现会导致链路堵塞、二层交换机管理缓慢、交换机设备CPU占用率极高等现象.基于对云南师范大学校园网的维护,分析了网络环路产生的原因及表现,并提出相应的对策来解决及预防网络环路.

The network loop has the characteristics of high concealment and trouble shooting, and it will cause the congestion of the road, the slow management of the two layer switch, and the high occupancy rate of the CPU of the gateway switch equipment. Based on the maintenance of the campus network of Yunnan Normal University, this paper analyzes the way and performance of the network loop, and puts forward the corresponding countermeasures to solve and prevent the network loop.
