Configuring a PVC
In PVC mode, the network administrator configures the switching entries and assigns VPI/VCI values. You
can configure the PVCs by using the assigned VPI/VCI values. If the ATM interfaces of two ATM devices
are directly connected, you must configure the same VPI/VCI values for the interfaces.
To configure a PVC:

2. Enter ATM interface view
or ATM subinterface view.
interface atm { interface-number |

PVC view.
pvc { pvc-name [ vpi/vci ] | vpi/vci }
By default, no PVC is created.
4. Bring up the PVC.
undo shutdown By default, the PVC is up.
Configuring a PVC-group
A PVC-group can share traffic load among PVCs in it by transmitting IP packets of different priorities
through different PVCs.
You can configure the priority of IP packets carried by each PVC. An IP packet is transmitted through the
PVC corresponding to the priority of the IP packet. If no corresponding PVC is found, the IP packet is
transmitted through the default PVC. If no default PVC is configured, the IP packet is transmitted through
PVCs not configured with priorities in turn. If all PVCs are configured with priorities, the IP packet is
dropped.
If a data packet is not an IP packet, it is transmitted through all PVCs in the PVC-group in turn.
All PVCs in a PVC-group obtain the encapsulation type, protocol type, and interface from the PVC-group.
To configure a PVC-group:
