18、限流方法：

Cisco设备制定限流策略以及应用：

Switch# conf t

Switch (config)# access-list 1 permit any

Switch (config)# class-map match-all c9M

Switch (config-cmap)# match access-group 1

Switch (config-cmap)# exit

Switch(config)# policy-map p9M

Switch (config-pmap)# class c9M

Switch (config-pmap-c)# police 9000000 4096 exceed-action drop

Switch (config-pmap-c)# exit

Switch# conf t

Switch(config)# interface f0/13

Switch(config-if)# service-policy input p9M
