389The fr inarp command configured on an FR main interface also applies to itssubinterfaces.Example # Enable InARP at all PVCs of the frame relay interface Serial 2/0. system-view[Sysname] interface serial 2/0[Sysname-Serial2/0] fr inarpfr interface-typeSyntax fr interface-type { dce | dte | nni }undo fr interface-typeView Interface viewParameter dce: Set the type of frame relay interface to DCE (Data Circuit-terminatingEquipment).dte: Set the type of frame relay interface to DTE (Data Terminal Equipment).nni: Set the type of frame relay interface to NNI (Network-to-Network Interface).Description Use the fr interface-type command to set the frame relay interface type.Use the undo fr interface-type command to restore the default frame relayinterface type.By default, the frame relay interface type is DTE.In frame relay, there are two communicating parties, namely, the user side andnetwork side. The user side is called Data Terminal Equipment (DTE), and thenetwork side is called Data Communications Equipment (DCE). In a frame relaynetwork, the interface between the frame relay switches is Network-to-NetworkInterface (NNI), and the corresponding interface adopts the NNI operating view. Ifthe device is used as frame relay switching, the frame relay interface shouldoperate in the NNI view or DCE mode. The system supports the three modes.While configuring the frame relay interface type as DCE or NNI, it is unnecessary toperform the fr switching command in the System view. Please note that this isdifferent from the mainstream equipment in the communications field.Example # Set the type of the frame relay interface Serial 2/0 to DCE. system-view[Sysname] interface serial2/0[Sysname-Serial2/0] fr interface-type dce
