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. IP packets are transmitted through the PVC corresponding to the priority of the IP packets.
If no corresponding PVC is found, the IP packets are transmitted through the default PVC.
If no default PVC is configured, the IP packets are distributed across the PVCs that are not configured with priorities on a per-packet basis.
If all PVCs are configured with priorities, the IP packets are dropped.
Data packets that are not IP packets are distributed across all PVCs in the PVC group on a per-packet basis.
All PVCs in a PVC group obtain the encapsulation type and protocol type from the PVC group.
To configure a PVC group:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter ATM interface view or ATM subinterface view. | interface atm { interface-number | interface-number.subnumber } | N/A |
3. Create a PVC group and enter PVC group view. | pvc-group group-number | By default, no PVC groups exist. |
4. Create a PVC and enter PVC view. | pvc { pvc-name [ vpi/vci ] | vpi/vci } | By default, no PVCs exist. |
5. Configure priority of IP packets carried by the PVC. | precedence { min-number [ to max-number ] | default } | By default, no priority is configured. |
6. Bring up the PVC. | undo shutdown | By default, the PVC is up. |
