使用以太网交换机，不会将数据包发送到所有端口，但是许多最新的交换机都提供了一个管理端口，该端口会将信息发送到所有的端口。
With Ethernet switches, packets are not echoed to all ports, but many modern switches provide a management port where the information is echoed.
注意，现代交换机不会将 Ethernet数据包发送到每一个端口上，这通常会限制您从当前主机获取的信息量。
Note that with modern switches the Ethernet packets are not echoed to every port, which often limits the information you can extract to the current host.
