Abstract: Based on 802.1x, this paper proposes an improved scheme for network user authentication management. The behavior of online users is controlled by the background detection server. To force the illegal users to log out is through Simple Network Management Protocol(SNMP) which drives the switch to work. This mechanism is transparent to the users, so it can strengthen the advantage of active management, and solve access control problems such as IP embezzlement and conflict, MAC lift.

摘要： 提出一种基于802.1x协议的网络用户认证管理改进方案。利用后台检测服务器监控在线用户的行为，通过简单网络管理协议向接入交换机发送指令，强制违规用户下线，解除异常下线的用户连接。该方案对用户透明，增强了主动管理优势，有效解决了校园网内IP地址盗用和冲突、MAC搭载等接入控制问题。
