理解和配置802.Q 802.1s和802.1w生成树协议

交换机的基本功能相当于一个透明的网桥网桥不能修正它所转发的帧；通过在端口上侦听数据帧中的源MAC地址，网桥能学习到其它设备的MAC，网桥搭建一个MAC表，交换机使用此表基于政策MAC进行数据帧的转发关于具有政策组播或广播MAC地址的数据包，网桥有必要将它转发到除开始接收广播的端口以外的其他一切端

(The basic function of the switch is equivalent to a transparent bridge. The bridge cannot modify the frame it forwards; by listening to the source MAC address in the data frame on the port, the bridge can learn the MAC of other devices, and the bridge builds a MAC address. Table, which is used by the switch to forward data frames based on the policy MAC. For a packet with a policy multicast or broadcast MAC address, it is necessary for the bridge to forward it to everything other than the port that started receiving the broadcast.
