Creating Policy Lists for ATM

In the following example, you create two policies: one for CBR traffic and one for UBR traffic. One policy is attached to an interface that contains CBR traffic and the other to an interface that contains UBR traffic.

  1. Create a CBR policy list.
    host1(config)#atm policy-list polCbr host1(config-policy-list)#
  2. Create the classification group and assign a strict priority traffic class and color green.
    host1(config-policy-list)#classifier-group * host1(config-policy-list-classifier-group)#traffic-class strict-priority host1(config-policy-list-classifier-group)#color green
  3. Exit Policy List Configuration mode to save the configuration.
    host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#exit host1(config)#
  4. Create a UBR policy that maps to the strict best-effort traffic class and color red.
    host1(config)#atm policy-list polUbr host1(config-policy-list)#classifier-group * host1(config-policy-list-classifier-group)#traffic-class best-effort host1(config-policy-list-classifier-group)#color red
  5. Exit Policy List Configuration mode to save the configuration.
    host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#exit host1(config)#
  6. Attach the policies to ATM subinterfaces.
    host1(config)#interface atm 0/0.100 host1(config-if)#atm policy input polUbr statistics enabled host1(config-if)#exit host1(config)#interface atm 0/0.101 host1(config-if)#atm policy input polCbr statistics enabled host1(config-if)#exit
  7. Display the policy lists.
    host1#show atm subinterface atm 0/0.100
