Configuring Frame Relay SwitchingConfiguring Frame RelayConfiguring a Frame Relay DTE Device, DCE Switch, or NNI SupportYou can configure an interface as a DTE device or a DCE switch, or as a switch connected to a switchto support NNI connections. (DTE is the default.) To do so, use the following command in interfaceconfiguration mode:CommandRouter(config-if)# frame-relay intf-type [dce | dte| nni]PurposeConfigures a Frame Relay DTE device or DCE switch.Creating Switched PVCsTo create a switched PVC over ISDN, or to create a switched PVC on which traffic shaping, trafficpolicing, and congestion management can be configured, use the following command in globalconfiguration mode:CommandRouter(config)# connect connection-name interface dlciinterface dlciPurposeDefines connections between Frame Relay PVCs.To create a switched PVC with a static route, use the following command in interface configurationmode:CommandRouter(config-if)# frame-relay route in-dlci interfaceout-interface-type out-interface-number out-dlciPurposeSpecifies a static route for PVC switching.Note Static routes cannot be configured over tunnel interfaces on the Cisco 800 series, 1600 series, and 1700series platforms. Static routes can only be configured over tunnel interfaces on platforms that have theEnterprise feature set.Identifying a PVC As SwitchedBefore you can associate a map class with a switched PVC, you must identify the PVC as being switched.To identify a PVC as switched, use the following command in interface configuration mode:CommandRouter(config-if)# frame-relay interface-dlci dlci switchedPurposeIdentifies a PVC as switched.22
