Point-to-Point PVCs

The procedure for setting up a PVC connection between two end nodes through the SmartSwitch 9A100 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).

The example above creates a PVC between ports C1 and B2 with VPI/VCI = 0/100.
3. Plug the end nodes into the specified SmartSwitch 9A100 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.
