Configure VLAN-based Rate Limiting

1. In privileged EXEC mode, access global configuration mode.
   

   device# configure terminal
   

2. Create the class map and access its configuration mode.
   

   device(config)# class-map c2
   

3. Add a match statement to the VLAN.
   

   device(config-classmap)# match vlan 500
   

4. Access global configuration mode.
   

   device(config-classmap)# exit
   

5. Create the policy map and access its configuration mode.
   

   device(config)# policy-map p2
   

6. Add the class map to the policy map and access the policy-class configuration mode.
   

   device(config-policymap)# class c2
   

7. Configure the class map.
   

   device(config-policymap-class)# police cir 100000 cbs 6000
   

   This step configures the committed information rate for the class map.
8. Access global configuration mode.
   

   device(config-policymap-class)# exit
   device(config-policymap)# exit
   

9. Access interface configuration mode for the interface where you want to apply the policy map.
   

   device(config)# interface ethernet 1/1
   

10. Apply the policy map to the interface.
    

    device(conf-if-eth-1/1)# service-policy in p2
    

11. Access global configuration mode.
    

    device(conf-if-eth-1/1)# exit
    

12. (Optional) Apply the policy map globally.
    

    device(config)# qos service-policy in p2

The following example summarizes the commands in this procedures.

device# configure terminal
device(config)# class-map c2
device(config-classmap)# match vlan 500
device(config-classmap)# exit
device(config)# policy-map p2
device(config-policymap)# class c2
device(config-policymap-class)# police cir 100000 cbs 6000
device(config-policymap-class)# exit
device(config-policymap)# exit
device(config)# interface ethernet 1/1
device(conf-if-eth-1/1)# service-policy in p2
device(conf-if-eth-1/1)# exit
device(config)# qos service-policy in p2
