生成树协议(spanning tree protocol,STP)是一种通过将环形网络拓扑从逻辑上优化成树形结构的重要协议,正确配置STP对于二层网络性能有着直接影响.本文从兰州管制区一起甚高频电台监控大面积掉线故障入手,详细分析了故障原因及排查过程,引出STP在二层网络中的作用,并详细介绍了STP的功能以及运行机制,对于网络维护单位及个人具有一定的参考价值.
Exploring STP from a Large Area Disconnection Fault of Radio Monitoring
Spanning tree protocol(STP)is an important protocol that logically optimizes the ring network topology into a tree structure.Proper configuration of STP has a direct impact on the performance of the two-layer network.This paper starts with a large area disconnection fault of VHF radio monitoring in Lanzhou control area,analyzes the cause of the fault and the troubleshooting process in detail,brings in to the role of STP in the two-layer network,and introduces the function and operation mechanism of STP in detail.It has certain reference value for network maintenance units and individuals.
