The fr inarp command configured on an FR main interface also applies to its subinterfaces.

Example # Enable InARP at all PVCs of the frame relay interface Serial 2/0.

Parameter dce: Set the type of frame relay interface to DCE (Data Circuit-terminating Equipment).

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-typecommand to set the frame relay interface type.

Use the undo fr interface-typecommand to restore the default frame relay interface type.

By default, the frame relay interface type is DTE.

In frame relay, there are two communicating parties, namely, the user side and network side. The user side is called Data Terminal Equipment (DTE), and the network side is called Data Communications Equipment (DCE). In a frame relay network, the interface between the frame relay switches is Network-to-Network Interface (NNI), and the corresponding interface adopts the NNI operating view. If the device is used as frame relay switching, the frame relay interface should operate 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 to perform the fr switching command in the System view. Please note that this is different from the mainstream equipment in the communications field.

Example # Set the type of the frame relay interface Serial 2/0 to DCE.
