Switch Administration | Setting Up PVC Connections |
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 | 6 | 6 |

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 |

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.
