Local Template-Based ATM PVC Provisioning
First Published: February 3, 2003
Last Updated: November 20, 2009The Local Template-Based ATM Provisioning feature enables ATM permanent virtual circuits (PVCs) to be provisioned automatically as needed from a local configuration. ATM PVC autoprovisioning can be configured on a PVC, an ATM PVC range, or a virtual cicuit (VC) class. If a VC class configured with ATM PVC autoprovisioning is assigned to an interface, all the PVCs on that interface will be autoprovisioned; this configuration is sometimes referred to as an infinite range.

Restrictions for Local Template-Based ATM PVC Provisioning
The number of PVCs that can be established on an interface that is configured as an infinite range is limited to the maximum number of VCs that the platform can support.
Information About Local Template-Based ATM PVC Provisioning
Autoprovisioned ATM PVCs are not created until there is activity on the virtual path identifier (VPI)/virtual channel identifier (VCI) pair. When the interface is disabled and reenabled using the shutdown and no shutdown commands, autoprovisioned PVCs that are part of a PVC range or infinite range are removed upon shutdown and are not reestablished until the first incoming packet triggers PVC creation. During router reload, autoprovisioned PVCs are created when there is activity on the connection.
The total number of VCs that can be configured on an ATM port adapter is limited by the capacity of port adapter. In cases of ATM link oversubscription, where a PVC range or infinite range is configured to provision more PVCs than the port adapter allows, the PVCs can be configured with a timeout so that they can be dynamically brought down as needed. When the timeout expires, the idle PVCs are removed, allowing the PVC range or infinite range of PVCs to share system resources.
ATM PVC local autoprovisioning supports the following applications: PPP over ATM, PPP over Ethernet, ATM routed bridge encapsulation, and routed RFC 1483.
The Local Template-Based ATM Provisioning feature enables ATM PVCs to be created automatically as needed from a local configuration, making the provisioning of large numbers of digital subscriber line (DSL) subscribers easier, faster, and less prone to error.
How to Configure Local Template-Based ATM PVC Provisioning
This section contains the following tasks:
•Configuring ATM PVC Local Autoprovisioning in a VC Class (required)
•Configuring ATM PVC Local Autoprovisioning on a PVC (required)
•Configuring ATM PVC Local Autoprovisioning on an ATM PVC Range (required)
•Configuring ATM PVC Local Autoprovisioning on PVC Within a Range (required)
•Verifying ATM PVC Autoprovisioning (required)
•Monitoring and Maintaining ATM PVC Local Autoprovisioning (optional)
Configuring ATM PVC Local Autoprovisioning in a VC Class
Perform this task to enable ATM PVC local autoprovisioning in a VC class. A VC class configured with ATM PVC autoprovisioning can be assigned to an ATM interface, an ATM PVC, an ATM PVC range, and an ATM PVC with a range.
Note If a VC class that is configured with ATM PVC autoprovisioning is assigned to an ATM interface, all PVCs on the interface will be autoprovisioned.

Configuring ATM PVC Local Autoprovisioning on PVC Within a Range
Perform this task to enable ATM PVC autoprovisioning on a PVC within an ATM PVC range. ATM PVC local autoprovisioning can also be configured on a PVC within a range by assigning a VC class that has been configured with ATM PVC local autoprovisioning to the PVC.
SUMMARY STEPS
1. enable

DETAILED STEPS
Verifying ATM PVC Autoprovisioning
Perform this task to verify if ATM PVC local autoprovisioning is configured and working correctly.
Step 1 Enter the show running-config command to verify that the configuration is correct.
Step 2 Enter the show atm pvc command. PVCs that have been autoprovisioned will have the value "PVC-A" ("A" stands for automatic) in the Type field.
