1、设置ACL

access-list 102 permit ip host 192.168.10.2 any

access-list 102 permit ip any host 192.168.10.2

access-list 103 permit ip host 192.168.10.3 any

access-list 103 permit ip any host 192.168.10.3

2、定义类

class-map match-all 102

match access-group 102

class-map match-all 103

match access-group 103

3、将类加入策略中

policy-map xiansu

class 102

police 1024000 128000 conform-action transmit exceed-action drop

class 103

police 1024000 128000 conform-action transmit exceed-action drop

4、将策略加入端口中

interface FastEthernet0/0

service-policy input xiansutest

service-policy output xiansutest

针对某个网段进行限速(限定的是总带宽)

（1）设置ACL

access-list 110 permit ip 192.168.10.0 0.0.0.255 any

access-list 102 permit ip any 192.168.10.0 0.0.0.255

（2）定义类

class-map match-all 110

match access-group 110

（3）设置策略

policy-map xiansu110

class 110

police 10240000 1280000 conform-action transmit exceed-action drop

（4）将策略加入端口

interface FastEthernet0/0

service-policy input xiansu110

service-policy output xiansu110
