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
定义类
class-map match-all 102
match access-group 102
class-map match-all 103
match access-group 103
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
将策略加入端口中
interface FastEthernet0/0
service-policy input xiansu
service-policy output xiansu
针对摸个网段进行限速（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
