Usage guidelines
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.
A PVC belongs to one PVC-group.
This command is applicable to ATM P2MP subinterface, but not to ATM P2P subinterface.
The number of a PVC-group is unique on an interface (including interface and subinterface).
Examples
# Create a PVC-group numbered 1.
<Sysname> system-view
[Sysname] interface atm 2/4/0
[Sysname-ATM2/4/0] pvc-group 1
[Sysname-ATM2/4/0-pvc-group-1]
