Virtual Ports and Static Connections PVCConnections

Example: Create a point-to-multipoint connection between a broadcasting workstation on port 7a1 and three other workstations connected to ports 7a2, 7a3, and 7a4.

1.Use add trafficdescriptor to create two new traffic descriptors, one for the forward direction, the other for the backward direction. For this example, for the forward traffic descriptor, we select UBR and accept the defaults.

SmartSwitch # add trafficdescriptor		— This is the forward descriptor
TrafficType(UBR)	:	— We use UBR for this example
TrafficDescriptorType(11)	:
PCRCLP01(100)	:	— Take the default values
QOSCLASS(0)	:
AalType(5)	:

SmartSwitch #

However, on a point-to-multipoint connection there should be no traffic in the backward direction, so we define the backward traffic descriptor with its Cell Loss Priorities set to zero (0)

SmartSwitch # add trafficdescriptor
TrafficType(UBR)	:	— This is the backward traffic descriptor
TrafficDescriptorType(11)	:
PCRCLP01(100)	: 0 — Set PCRCLP01 to zero
QOSCLASS(0)	:
AalType(5)	:

SmartSwitch #

2.Use show trafficdescriptor to obtain the new traffic descriptors’ index numbers.

In the example above, traffic descriptor three (3) will be used in the forward direction, and traffic descriptor four (4) will be used in the backward direction.

3.Use add pvc to successively create point-to-multipoint PVCs for ports 7a2, 7a3, and 7a4.

SmartSwitch # add pvc
ConnType(PTP)	: pmp
Port-1-Number()	: 7a1
Port-1-VPCI()	: 0
Port-1-VCI()	: 101
Port-2-Number()	: 7a2
Port-2-VPCI()	: 0
Port-2-VCI()	: 101
Port1-to-Port2TrafficDescriptorIndex()	: 3
Port2-to-Port1TrafficDescriptorIndex()	: 4

4.Perform step 3 for ports 7a3 and 7a4.
