Chapter 8 Configuring ATM Permanent Virtual Circuit Autoprovisioning
ATM PVC Autoprovisioning
Example 8-7 enables autoprovisioning on PVC 100/100 in PVC range 100/100 to 100/200.
Example 8-7 Enabling ATM PVC Autoprovisioning on a PVC Within a PVC Range
Router(config)# int atm 3/0/0.1 multipoint
Router(config-subif)# atm pppatm passive
Router(config-subif)# range pvc 100/100 100/200
Router(config-subif-atm-range)# pvc-in-range 100/100
Router(config-subif-atm-range-pvc)# create on-demand
Router(config-subif-atm-range-pvc)# idle-timeout 300
Creating an On-Demand PVC With Infinite Range
To create an on-demand PVC with infinite range, enter the following commands beginning in global
configuration mode:
Example 8-8 creates a VC class named myclass, enables PVC autoprovisioning on the class, and attaches
the class to the main ATM interface. All the PVCs on the main interface will be autoprovisioned; this
configuration is also known as infinite range.
Example 8-8 Configuring an On-Demand PVC With Infinite Range
Router(config)# vc-class atm myclass
Router(config-vc-class)# create on-demand
Router(config-vc-class)# idle-timeout 300
Router(config)# int atm 3/0/0
Router(config-if)# class-int myclass
Command Purpose
Step 1 Router(config)# vc-class atm name Creates a VC class and enters vc-class configuration mode.
Step 2 Router(config-vc-class)# create on-demand Enables PVC autoprovisioning.
Note Configure additional VC parameters as appropriate. For
more information, see the
“VC Class” section on page 8-3
or the “Creating a VC Class Examples” section in the
Cisco IOS Wide-Area Networking Configuration Guide.
Step 3 Router(config-vc-class)# idle-timeout
[time-out-in-seconds]
[minimum-traffic-in-kbps]
(Optional) Enables the idle-timeout timer on the on-demand PVC.
The default time-out-in-seconds is 0 (no idle-timeout).
The Cisco 10000 series router waits until the traffic on a
particular VC is processed before tearing down the VC, even if
you specify the minimum-traffic-in-kbps option or if the VC is
idle during the idle-timeout period.
Step 4 Router(config)# interface atm slot/0 Specifies the ATM interface.
You can configure infinite range only on a main ATM interface.
When you use the class-int command to attach an ATM VC class
to a subinterface, the create on-demand command is ignored.
Step 5 Router(config-if)# class-int name Attaches a VC class to an ATM interface.
