interface, and not on an ATM 1483 subinterface that is stacked above an ATM major
interface.
To create a control PVC, you issue the pvc command from Interface Configuration
mode. However, unlike the other tasks in this section, configuring a control PVC with
the
pvc command does not access ATM VC Configuration mode.
For example, the following commands create a control PVC with VCD 10, VPI 0,
VCI 16, and ILMI encapsulation.
host1(config)# interface atm 3/0
host1(config-if)# pvc 10 0/16 ilmi
host1(config-if)#
Regardless of whether you use the pvc command or the atm pvc command to create
a control PVC, you cannot modify the VCD, VPI, or VCI values after they have been
configured.
pvc
■
Use from Interface Configuration mode to create a control PVC for Integrated
Local Management Interface (ILMI).
■
To create a control PVC, specify the VCD, VPI and VCI (in the format vpi / vci ),
and the ilmi keyword.
■
Example
host1(config-if)# pvc 5 0/5 ilmi
■
Use the no version to remove the specified control PVC from the router.

Creating Data PVCs
A data PVC, also referred to as a data circuit, is an ATM PVC that carries data. You
must create a data PVC on an ATM 1483 subinterface that is stacked above an ATM
major interface, and not on the ATM major interface itself.
To create a data PVC, you issue the pvc command from Subinterface Configuration
mode to access ATM VC Configuration mode. From ATM VC Configuration mode,
you can then do either of the following:
■
Issue the exit command, which creates a data PVC that uses default values for
service category (unspecified bit rate without a peak cell rate), encapsulation
type (
aal5snap ), F5 OAM (disabled), and Inverse ARP (disabled).
■
Issue commands to configure or modify data PVC attributes including the service
category, encapsulation type, F5 OAM, and Inverse ARP.
For example, the following commands create a data PVC with VCD 32, VPI 0, VCI 100
and default values for the other attributes. Issuing the
exit command causes the
configuration to take effect.
