18、这一新的VLAN特性就是专用VLAN(private VLAN, pVLAN)。专用VLAN是第2层的机制，在同一个2层域中有两类不同安全级别的访问端口。与服务器连接的端口称作专用端口(Private port)，一个专用端口限定在第2层，它只能发送流量到混杂端口，也只能检测从混杂端口来的流量。混杂端口(Promioscuous port)没有专用端口的限定，它与路由器或第3层交换机接口相连。简单地说，在一个专用VLAN内，专用端口收到的流量只能发往混杂端口，混杂端口收到的流量可以发往所有端口(混杂端口和专用端口)。 专 用 VLAN 的 应 用 对于保证城域接入网络的数据通讯的安全性 是 非 常 有 效的用户只需与自己的缺省网关连接，一个专用VLAN不需要多个VLAN 和IP 子 网 就 提 供 了 具备第二层数据通讯安全性的连接，所有的用户都接入专用 VLAN，从而实现了所有用户与缺省网关的连接，而与专用VLAN内的其他用户没-
