Cut-through switches do not perform any error checking of the frame because the switch looks only for the frame's destination MAC address and forwards the frame out the appropriate switch port.
直通式交换机不执行任何帧错误检查，它只查找帧的目的MAC地址，并从相应的交换机端口将帧转发。
Respectively through the various contacts, in order to dial the corresponding limit switches and over current relay normally closed contacts, to see the ability to cut off the control current.
①分别接通各个接触器，依次拨通相应的限位开关和过电流继电器常闭触头，查看其切断控制电流的能力。
Some switches can be configured to perform cut-through switching on a per-port basis until a user-defined error threshold is reached, when they automatically change to store-and-forward mode.
有些交换机可配置进行裁剪通过开关以每港口基础直到用户定义阈值误差达到当他们自动改变存储转发模式。
