The example shows the final step of assigning your X.25 profile to the DLCI interface by using theframe-relay interface-dlci command, and then assigning X.25 routes to DLCIs 20, 30, and 40 using thex25 route command.The new x25 profile command mode (config-x25) can be seen in this example. This mode is used forconfiguring the parameters of your X.25 profile. For a complete description of this command and mode,refer to the x25 profile command section in the chapter “X.25 and LAPB Commands” in the Cisco IOSWide-Area Networking Command Reference.This example assumes that you already have Frame Relay enabled on your router.Router(config)# x25 routingRouter(config)# x25 profile NetworkNodeA dceRouter(config-x25)# x25 htc 128Router(config-x25)# x25 idle 5Router(config-x25)# x25 accept-reverseRouter(config-x25)# x25 modulo 128Router(config-x25)# endRouter(config)# x25 profile NetworkNodeB dceRouter(config-x25)# x25 address 1111Router(config-x25)# endRouter(config)# interface serial1Router(config-if)# encapsulation frame-relayRouter(config-if)# frame-relay interface-dlci 20Router(config-fr-dlci)# x25-profile NetworkNodeARouter(config-fr-dlci)# endRouter(config)# interface serial1Router(config-if)# frame-relay interface-dlci 30Router(config-fr-dlci)# x25-profile NetworkNodeARouter(config-fr-dlci)# endRouter(config)# interface serial1Router(config-if)# frame-relay interface-dlci 40Router(config-fr-dlci)# x25-profile NetworkNodeBRouter(config-fr-dlci)# endRouter(config)# x25 route 2000 interface serial1 dlci 20Router(config)# x25 route 3000 interface serial1 dlci 30Router(config)# x25 route 4000 interface serial1 dlci 40CMNS Switching ExampleThe following example illustrates enabling CMNS and configuring X.25 routes to the available CMNShost and the PDN connectivity:interface ethernet 0cmns enable!interface serial 073
