摘　　要：网络侦听技术是网络安全与管理技术中一项非常重要且备受人们关注的技术。但与在共享环境下不同,在交换环境下,要进行有效的网络侦听并不简单。介绍了交换环境网络侦听的若干方法,并针对每种方法,设计了具体的实验方案。通过该实验,可以使学生掌握交换环境网络的侦听方法,更好地理解交换机工作原理、网络侦听原理及交换环境网络存在的安全隐患,提高学生分析问题、解决问题以及综合应用知识的能力。Sniffer is an important technology of network security and management,and has been achieved more and more attentions.But putting sniffer into practice effectively in switch networks is not simple which differ from that in shared networks.This paper introduces a number of methods of sniffer in switch networks,and for each method,designs a specific experiment.Through these experiments,students can master these methods of sniffer in switch networks,understand the working principles of switches and sniffer as well as risks in switch networks deeply,improve their abilities of analyzing and solving actual problems.
