different priorities.
A primary PVC refers to the one based on which a PVC-group is created on an ATM interface. A
secondary PVC refers to a PVC created in a PVC-group.
To configure PVC service mapping:
Step Command Remarks
1. Enter system view.

N/A
2. Enter ATM subinterface
view.
interface atm
{ interface-number
| interface-number.subnumber }
N/A
3. Create PVC, and enter its
view.
pvc
{ pvc-name [ vpi/vci ] |
vpi/vci }
N/A
4. Return to ATM interface
view.

6. Add a PVC to the
PVC-Group.
pvc
{ pvc-name [ vpi/vci ] |
