Soft PVC and PVP Connections

Virtual Ports and Static Connections

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

SmartSwitch #

Note

The

DestinationSelectType

determines which vpi/vci pair is used on the target

switch. The possible settings are

REQUIRED

and

ANY

. If

DestinationSelectType

set to

REQUIRED

, the specified target vpi/vci is set at the target switch. If

ANY

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
