802.1X 标准应用于试图连接到端口或其它设备(如Cisco Catalyst交换机或Cisco Aironet系列接入点)(认证方)的终端设备和用户(请求方)。认证和授权都通过鉴权服务器(如Cisco Secure ACS)后端通信实现。IEEE 802.1X提供自动用户身份识别，集中进行鉴权、密钥管理和LAN连接配置。 整个802.1x 的实现设计三个部分，请求者系统、认证系统和认证服务器系统。-The 802.1X standard applies to terminal equipment and the user attempts to connect to the port or other devices (such as Cisco Catalyst switches or Cisco Aironet Series access points) (certification square) (the requester). Authentication and authorization through backend authentication server (such as Cisco Secure ACS) communication. The IEEE 802.1X provided automatic user identification, centralized authentication, key management and LAN connection configuration. Three parts to the entire 802.1x achieve design, the requester systems, authentication systems, and the authentication server system.
