　　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
