Soft PVC and PVP Connections Virtual Ports and Static Connections

5.On the source switch, use the add spvc command to create the soft PVC connection between the two switches:

SmartSwitch # add spvc
PortNumber()	: 7a1 — Port on source switch
SourceVpi(0)	: 0
SourceVci(32)	: 101
DestinationSelectType(REQUIRED)	: — See note below
DestinationVPI(0)	: 0
DestinationVCI(32)	: 102
TargetAddress()	: 22:22:22:22:22:22:22:22:22:22:22:22:22:22:22:22:22:22:22:22
TransmitTrafficDescriptorIndex()	: 3
ReceiveTrafficDescriptorIndex()	: 3
RetryInterval(10000)	:
RetryLimit(3)	:
RetryThreshold(1)	:
SmartSwitch #

Note The DestinationSelectType determines which vpi/vci pair is used on the target switch. The possible settings are REQUIRED and ANY. If DestinationSelectType is set to REQUIRED, the specified target vpi/vci is set at the target switch. If ANY is specified, the soft PVC uses the first available vpi/vci pair it finds on the target switch. If ANY is specified, enter the show spvctarget command on the target switch to determine the vpi/vci pair used.

Enter the show spvc command on the target switch to see the soft PVC and its current state:

SmartSwitch # show spvc
PortNumber(ALL)	:
SourceVpi(0)	: 0
SourceVci(32)	:	101

Note If you want to create soft PVCs that use VPI values other than zero (0), you must first use the set portconfig command to change the MaxVpiBits for the port from its default of zero (0) to a value that specifies a sufficient number of bits to create the VPI number. For example, if you want to use VPI = 3, change MaxVpiBits for that port to two (2). See Section 5.2 and Section 5.3 for more information about setting MaxVpiBits.
