Create class-map to categorize traffic

ip access-list extended Web-Server
permit ip host 10.0.0.1 any 
permit ip any host 10.0.0.1 
exit

class-map match-all Important-Traffic
   match access-group name Web-Server
exit

Create policy-maps (apply actions to classes)


 policy-map Super-Policy
   class Import-Trafffic
     bandwidth percent 50

Assign a policy to an interface (with a service-policy)

interface eth0/0
service-policy output Super-Poicy
bandwidth 1000

Verify Settings


show policy-map interface eth0/0

show class-map
