应用介绍
其实限速肯定是可以的，但是需要考虑一个具体的问题，一般接入路由器都作了地址转换，但是了解到路由器的操作步骤会发现如下的执行步骤：
check input rate limits ------->nat outside to inside------->check output rate limits
所以针对内部部分主机做限速策略，由于必须在ACL里面指定inside local 地址，所以应该在内网接口上应用service-policy output xxx，而不是在外网接口上的service-policy input xxx!
下面是一个具体的例子：
Router#sh run

最后的效果，可以达到限制内网除172.16.1.100的其他主机的下行速率在10KBps附近。
