Creating Policy Lists for Frame Relay

The following example creates a Frame Relay policy that on egress marks the DE bit to 1, and on ingress colors frames with a DE bit of 1 as red.

  1. Create the policy list used to mark egress traffic, then create the classifier group for packets conforming to CLACL frMatchDeSet. Add a rule that marks the DE bit as 1.
    host1(config)#frame-relay policy-list frOutputPolicyhost1(config-policy-list)#classifier-group frMatchDeSethost1(config-policy-list-classifier-group)#mark-de 1host1(config-policy-list-classifier-group)#exithost1(config-policy-list)#exit
  2. Create the policy list used for the ingress traffic. and create the classifier group conforming to CLACL frMatchDeSet. Add a rule that colors the ingress traffic.
    host1(config)#frame-relay policy-list frInputPolicyhost1(config-policy-list)#classifier-group frGroupAhost1(config-policy-list-classifier-group)#color redhost1(config-policy-list-classifier-group)#exithost1(config-policy-list)#exit
  3. Apply the policy lists.
    host1(config)#interface serial 5/0:1/1.1 host1(config-subif)#frame-relay policy output frOutputPolicy statistics enabled host1(config-subif)#ip address 10.0.0.1 255.255.255.0 host1(config-subif)#exit host1(config)#interface serial 5/1:1/1.1 host1(config-subif)#frame-relay policy input frInputPolicy statistics enabled host1(config-subif)#exit
  4. Display interface information to view the applied policies.
    host1#show frame-relay subinterface

    Number of sub-interface down transitions is 0

      In errors: 0                     Out errors: 0                   
      In discards: 0                   Out discards: 0                   
      In unknown protos: 0                   
    Frame relay policy input frInputPolicy
      classifier-group frMatchDeSet entry 1
         5 packets, 660 bytes
         color red
  5. Display the classifier list.
    host1#show classifier-list detailed
