Cisco路由器进行ip限速的配置方法

 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:

128733184 bytes total (100229120 bytes free)

 

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

 

*Apr 5 06:24:04.023: %IP_VFR-4-FRAG_TABLE_OVERFLOW: FastEthernet0/1: the fragment table has reached its maximum threshold 16
