Serial Port Configuration
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.

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.

16.13 Configuring the PVC Encapsulation Type
To set the encapsulation type to comply with the Internet Engineering Task Force (IETF) standard
(RFC 1490) the PVC configuration command
encapsulation
rfc1490
has to be used. Use this keyword
when connecting to another vendor's equipment across a Frame Relay network.

To set the encapsulation type to comply with RFC 1490

Example: Configuring the PVC Encapsulation Type
The following example sets the encapsulation type to comply with RFC 1490 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.
