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).
