For example, change VCCMask indexed combination zero (0) from VPI = 0 bits and VCI = 12 bits to
VPI = 3 bits and VCI = 9 bits.
1. Use set vccmask to change the VPI/VCI values to 3/9.
SmartCell ZX # set vccmask
MaskIndex(0) :
<replace the first VPI/VCI pair
VPIShift(0) : 3
VCIShift(12) : 9
SmartCell ZX #
2. Use the show vccmask command to see the new VPI/VCI combination.
SmartCell ZX # show vccmask
MaskIndex VpiShift VciShift
(In bits) (In bits)

0 3 9
<for index 0, VPI/VCI now equals 3/9
1 2 10
2 4 8

3. Use the set portconfig command to reconfigure a port to use the new values for VPI and VCI. For
example, to set up a PVC on port A1 using the new VPI/VCI bit ranges (3/9), enter
SmartCell ZX # set portconfig a1
MaxVPIBits(0) : 3
MaxVCIBits(12) : 9
InterfaceAddressType(PRIVATE) :
Trying to change VPI/VCI bits. This might affect existing PVCs.
Proceed any way?

4. Use show portconfig to see the change to port A1.
SmartCell ZX # show portconfig a1

PVCs can be configured for port A1 using VPI values from 0 to 7 and VCI values from 0 to 511.
Note Do not set the VCI part of the VCCMask to fewer than 5 bits.
