IP网络设备典型故障分析及其对策

针对IP网络设备在使用过程中产生的广播风暴、传输数据丢包、MP-group(Multilink-group,复用链路组)接口链路层运行PPP(Point to Point Protocol,点对点协议)异常等问题,结合华为S9300交换机设备、NE40E路由器设备的工作原理,对策略路由机理、STP(Spanning Tree Protocol生成树协议)、广播数据帧复制过程进行了研究和分析。并通过分析问题产生的机理,发现了目前网络数据配置存在的不足,提出了在核心层交换机上配置流过滤策略等应对措施和快速处理故障的方法,对系统进行了完善与改进,并优化了相关领域的应用,为维护人员在任务中迅速、合理地实施应急处置提供了参考。

Zhang Xiaojun, Han Li, Su Keyun.Typical failures of IP network equipment and response measures

To solve problems of IP network equipment in the course of use, including broadcast storm, transmission data packet loss, anomalies of MP Group (Multilink group) interface link layer in running PPP (Point to Point Protocol) protocol, the policy routing mechanization, STP (Spanning Tree Protocol) and the process of copying broadcast frames are studied based on the operation principles of Huawei S9300 switches and NE40E router equipment.Through analysis of the mechanism, the problem of the current network data configuration has been found and response measures including flow filtering strategy and fast processing fault trouble shooting in the core switch is proposed.The system has been improved and application in the relevant field is optimized in order to provide reference for maintenance personnel in rapid and rational emergency management.
