Switch Administration PVC Connections
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.
SmartCell ZX # add trafficdescriptor
<this is the forward descriptor
TrafficType(UBR) :
<we use UBR for this example
TrafficDescriptorType(11) :
PCRCLP01(100) :
<we take the default values

SCRCLP01(0) :

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)
md1 #add trafficdescriptor
<this is the backward descriptor
TrafficType(UBR) :
TrafficDescriptorType(11) :
PCRCLP01(100) :0
<we set everything to zero

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

In the example above, traffic descriptor six (6) will be used in the forward direction, and traffic descriptor seven (7)
will be used in the backward direction.
3. Use add pvc to successively create point-to-multipoint PVCs for ports B2, B3, and C1.
SmartCell ZX # add pvc

LowVPI() : 0

4. Perform step 3 for ports B3 and C1.
5. Connect the workstations to their respective ports.
