摘　　要：简要介绍802.1x协议的认证结构与认证机制,研究该认证机制下的一些问题与缺陷。首先,介绍基于端口控制的802.1x协议的认证原理及特点优势;其次,结合网管实践及调查研究分析探讨802.1x标准下认证存在的问题与缺陷。结论是基于802.1x协议的认证机制比传统认证有优势,但在安全控制与网络管理上暴露出一些问题与缺陷。This paper gave a brief introduction to authentication architecture ＆ mechanism of the 802. 1x protocol, presented some problems and flaws existed in this authentication mechanism. Frist, it introduced the authentication methods and advantage of 802. 1x for port - based network access control. Second, it studied and discussed some problems and flaws under this control based on the practice of network management and research. Conclusion is that comparing to conventional authentication mechanism, 802. 1x protocol has much advantage, but some problems and flaws existed in security control and network management.
