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.
host1(config)#interface atm 3/2.2
host1(config-subif)#pvc 32 0/100
host1(config-subif-atm-vc)#exit
host1(config-subif)#
Regardless of whether you use the pvc command or the atm pvc command to create a
data PVC, you cannot modify the VCD, VPI, or VCI values after they have been configured.
Use from Subinterface Configuration mode to create a data PVC and access ATM VC
Configuration mode, from which you can configure and modify individual PVC attributes
one at a time.
To create a basic data PVC with default values for service category, encapsulation
type, F5 OAM, and Inverse ARP, specify the VCD and the VPI and VCI (in the format
vpi/vci).
You must issue the exit command from ATM VC Configuration mode for the
configuration to take effect.
Example
host1(config-subif)#pvc 10 15/50
host1(config-subif-atm-vc)#exit
Use the no version to remove the specified data PVC from the router.
