Point-to-Point PVCs

The procedure for setting up a PVC connection between two end nodes through the SmartCell 6A000 consists of
specifying the ports and the virtual path and virtual channel identifiers (VPI and VCI).

For this example, we specify CBR as the traffic type, then take the remaining defaults. Enter the
command to obtain the index number of the new traffic descriptor. In this example, the index
trafficdescriptor
number is two (2).

2. Use to create the PVC; specify the ports through which the connection is established, the

VPI/VCI pair to use with each port, and the traffic descriptor to use.

The example above creates a PVC between ports C1 and B2 with VPI/VCI = 0/100.
3. Plug the end nodes into the specified SmartCell 6A000 ports (C1 and B2).
Configure each end node with the proper IP address, subnet mask, and VPI/VCI pair = 0/100.
4.
The end nodes can communicate with each other through the point-to-point PVC connection.

Point-to-Multipoint PVCs

Instructions in this section describe how to set up a point-to-multipoint connection through your SmartCell 6A000.
Example: Create a point-to-multipoint connection between a broadcasting workstation on port A1 and three other
workstations connected to ports B2, B3, and C1.
