摘　　要：PPPoE是一种广受欢迎的网络接入方式,随着网络设备制造技术的发展,目前市面上出现了较多集成的功能较为简单的PPPoE server的网络设备,很多集成的PPPoE server只能在一个VLAN上正常工作,而无法完成其他VLAN上的PPPoE认证,形成了一个多VLAN环境中的PPPoE认证难题。详细分析了VLAN、PPPoE技术原理以及多VLAN环境中PPPoE认证难题出现的原因,结合作者在网络实践中的案例,介绍了一种巧妙运用Hybrid端口技术解决该难题的方法。PPPoE is a popular mode in network access, with the development of manufacturing technology of network equipment, some network devices with simple PPPoE server are on sale on the market at present, but many these integrated PPPoE servers can only work in one VLAN, they can not finish PPPoE authentication for other VLANs in the same LAN, so a big problem appears in PPPoE authentication in multi-VLAN environment. This paper analyses both the technical principle of VLAN and PPPoE arid the cause of the problem in detail, it introduces a method to solve the problem through clever usage of Hybrid port technology ,and a successful case in network practice is provided.
