摘　　要：在网络中进行监听是维护、管理网络必须进行的操作。现如今,很多的局域网都已经换成了交换式网络,由于Sniffer监听的原理限制,在交换式网络中不能实现监听。论文详细阐述了网络监听的原理,在交换式网络中实现网络监听的技术和应用,并检测和防范网络中存在的监听。Conducting monitoring in the network is a necessary operation for maintenance and management network. Nowadays, many LANs have been changed into switching network. Because of the restriction by the principle of the Sniffer, the monitoring in switching network can not be realized. This paper describes in detail the principle of monitoring, the technology and application of monitoring in the switching network, detection and keeping away the network monitoring.
