在路由器上面按IP限速
http://net.it168.com/a2012/1127/1428/000001428031.shtml
【IT168技术】2811路由器来完成，本实验分两种方法来做，各有特点。
先看下路由器的flash:

以下是实验过程
access-list 102 permit ip 192.168.1.0 0.0.0.255 any
access-list 102 permit ip any 192.168.1.0 0.0.0.255
第二步：定义class-map ,调用第一步的ACL
class-map match-all 102
match access-group 102
第三步：定义policy-map，调用class-map，做速率限制
policy-map 102
class 102
police 256000 8000 conform-action transmit exceed-action drop
第四步：把policy-map应用到接口上
interface FastEthernet0/1
service-policy input 102
service-policy output 102
