问题解答

在计算机网络中、 混杂模式是有线网络接口控制器(NIC)或无线网络接口控制器(WNIC)的一种模式、它会使控制器将接收到的所有流量传递到中央处理器(CPU)、而不是仅传递控制器专门编程接收的帧。此模式通常用于在路由器或连接到有线网络的计算机上进行数据包查找(针对特定接口运行tcpdump)。

追加信息

IEEE 802 网络(如以太网或 IEEE 802.11)中,每个帧都包含一个目标MAC地址。在非混杂模式下、如果NIC收到帧、则它会将其丢弃、除非该帧是寻址到该NIC的MAC地址或广播或多播地址帧。但是、在混杂模式下、NIC允许所有帧通过、从而使计算机能够读取用于其他计算机或网络设备的帧。
