6 VIRTUAL PORTS AND STATIC
CONNECTIONS
6.1 PVC CONNECTIONS
The SmartSwitch 6500 supports Permanent Virtual Circuits (PVCs), both point-to-point and point-to-multipoint. Use
PVCs to connect devices (that do not support SVCs) to a switch’s local client. Also, use PVCs to make connections
through the SmartSwitch 6500 between devices that support only PVCs.
Use point-to-point PVCs to connect one end node to another for two-way communication. Use point-to-multipoint
PVCs to connect a broadcast end node to a group of receiving end nodes; traffic is one way.
Note PVCs use traffic descriptors to define their traffic characteristics. See Chapter 7,
"Traffic Management," Section 7.1.1 for further information on traffic
descriptors.
6.1.1 Point-to-Point PVCs
The procedure for setting up a PVC connection between two end nodes through the SmartSwitch 6500 consists of
specifying the ports and the Virtual Path Connection Identifier and Virtual Channel Identifiers (VPCI and VCI).
1. Use add trafficdescriptor to define a traffic descriptor to use with the PVC:
Smart6500 # add trafficdescriptor
Executing this command : add TrafficDescriptor
