16.12 Entering Frame Relay PVC Configuration Mode
The permanent virtual circuit (PVC) is a virtual circuit that is permanently established. PVCs save
bandwidth associated with circuit establishment and tear down in situations where certain virtual
circuits must exist all the time.
The Frame Relay network provides a number of virtual circuits that form the basis for connections
between stations attached to the same Frame Relay network.
The resulting set of interconnected devices forms a private Frame Relay group, which may be either
fully interconnected with a complete "mesh" of virtual circuits, or only partially interconnected.
In either case, each virtual circuit is uniquely identified at each Frame Relay interface by a Data Link
Connection Identifier (DLCI). In most circumstances, DLCIs have strictly local significance at each
Frame Relay interface.
Assigning a DLCI to a specified Frame Relay sub interface on the SmartNode 2300 series device is
done in the PVC configuration mode. The DLCI has to be in the range from 1 to 1022.
Note: There is a maximum of eight PVCs that can be defined.
Procedure
To enter the PVC configuration
Mode
Frame Relay
Command Purpose
Step 1 node (frm-rel)[ slot / port ]#pvc dlci Enters the PVC configuration mode by
assigning a DLCI number to be used on
the specified sub interface
Example: Entering Frame Relay PVC Configuration Mode
The following example enters the configuration mode for PVC with the assigned DLCI of 1 for Frame
Relay over the serial interface on slot 0 and port 0 of a SmartNode 2300 series device.
