1、　　抓取列表

1 Cisco1921#
2 
3 Cisco1921#conf t
4 
5 Cisco1921(config)#access-list 100 permit ip 12.172.1.0 0.0.0.255 any
6 
7 Cisco1921(config)#access-list 100 permit ip any 12.172.1.0 0.0.0.255

2、　　创建Class-Map

1 Cisco1921(config)#class-map match-all 10M
2 
3 Cisco1921(config-cmap)#match access-group 100
4 
5 Cisco1921(config-cmap)#exit

3、　　创建Policy-Map

 1 Cisco1921(config)#policy-map LIMIT
 2 
 3 Cisco1921(config-pmap)#class
 4 
 5 Cisco1921(config-pmap)#class 10M
 6 
 7 Cisco1921(config-pmap-c)#police cir 10000000 bc 10000000
 8 
 9 Cisco1921(config-pmap-c-police)#conform-action transmit
10 
11 Cisco1921(config-pmap-c-police)#exceed-action transmit
12 
13 Cisco1921(config-pmap-c-police)#violate-action drop

4、　　接口应用策略

1 Cisco1921(config)#int port-channel 1.12
2 
3 Cisco1921(config-subif)#service-policy input LIMIT
4 
5 Cisco1921(config-subif)#service-policy output LIMIT
