Cabletron Systems 6A000 manual Md1 #add trafficdescriptor

Switch Administration PVCConnections

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
PCRCLP0(0)	:
SCRCLP01(0)	:
SCRCLP0(0)	:
MBSCLP01(0)	:
MBSCLP0(0)	:
QOSCLASS(0)	:
AalType(5)	:
md1 #

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
PCRCLP0(0)	:
SCRCLP01(0)	:
SCRCLP0(0)	:
MBSCLP01(0)	:
MBSCLP0(0)	:
QOSCLASS(0)	:
AalType(5)	:

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
ConnType(PTP)	: pmp
LowPortID()	: a1
LowVPI()	: 0
LowVCI()	: 101
HighPortID()	: b2
HighVPI()	: 0
HighVCI()	: 101
FwdTrafficDescriptorIndex()	: 6
BkwTrafficDescriptorIndex()	: 7
SmartCell ZX #

4.Perform step 3 for ports B3 and C1.

5.Connect the workstations to their respective ports.
