PVC Connections Switch Administration
4.5.1 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).
1. Use add trafficdescriptor to define a traffic descriptor to use with the PVC.
SmartSwitch # add trafficdescriptor
TrafficType(UBR) : cbr
TrafficDescriptorType(2) :
PCRCLP01(100) :
PCRCLP0(0) :
SCRCLP01(0) :
SCRCLP0(0) :
MBSCLP01(0) :

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

2. Use add pvc 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.
SmartSwitch # add pvc
ConnType(PTP) :
LowPortID() : c1
<we specify port c1
LowVPI() : 0
<we specify VPI = 0
LowVCI() : 100
<we use VCI = 100
HighPortID() : b2
<we specify port b2
HighVPI() : 0
HighVCI() : 100
FwdTrafficDescriptorIndex() : 2
<we use our created traffic descriptor
BkwTrafficDescriptorIndex() : 2
<we use our created traffic descriptor
SmartSwitch #
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).
4. Configure each end node with the proper IP address, subnet mask, and VPI/VCI pair = 0/100.
The end nodes can communicate with each other through the point-to-point PVC connection.
