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.

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 frOutputPolicy host1(config-policy-list)#classifier-group frMatchDeSet host1(config-policy-list-classifier-group)#mark-de 1 host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#exit
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 frInputPolicy host1(config-policy-list)#classifier-group frGroupA host1(config-policy-list-classifier-group)#color red host1(config-policy-list-classifier-group)#exit host1(config-policy-list)#exit
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
