To configure and apply a VC class directly to a PVC, complete the following steps beginning in global
configuration mode:
To configure and apply a VC class to an interface or subinterface, complete the following steps
beginning in global configuration mode:
Example—VC Classes
In the following example, ATM 0/0/0 is assigned the VC class “snap.” PVC0/40 and PVC0/41 inherit
the properties of VC class “snap.” PVC 0/42 is configured to override the VC class properties by
assigning a static IP address. ATM subinterface 0/0/0.2 inherits the properties of ATM 0/0/0, so
PVC0/43 also inherits the properties of VC class “snap.” By assigning a different VC class, “ppp-atm,”
PVC0/44 overrides the properties of the “snap” VC class.

Command Purpose
Step1
Router(config)# vc-class atm name
Creates or selects a map class.
Step2
Router(config-vc-class)# encapsulation aal-encap
[ppp virtual-template number]
Configures the ATM adaptation layer (AAL) and
encapsulation type. Optionally configures a PVC to
use a virtual-template as the default PPP interface
configuration.
Step3
Router(config-vc-class)# exit
Returns to global configuration mode.
Step4
Router(config)# interface atm 0/0/0
[.subinterface-number {multipoint | point-to-point}]
Specifies the ATM interface and optional
subinterface.
Step5
Router(config-if)# pvc [name] vpi/vci
Configures a PVC on the ATM interface or
subinterface.
Step6
Router(config-atm-vc)# class-vc vc-class-name
Associates a VC class with the PVC.
Command Purpose
Step1
Router(config)# vc-class atm name
Creates or selects a map class.
Step2
Router(config-vc-class)# encapsulation aal-encap
[ppp virtual-template number]
Configures the ATM adaptation layer (AAL) and
encapsulation type. Optionally configures a PVC to
use a virtual-template as the default PPP interface
configuration.
Step3
Router(config-vc-class)# exit
Returns to global configuration mode.
Step4
Router(config)# interface atm 0/0/0
[.subinterface-number {multipoint | point-to-point}]
Specifies the ATM interface and optional
subinterface.
Step5
Router(config-if)# class-int vc-class-name
Associates a VC class to the interface or subinterface.
Step6
Router(config-if)# pvc [name] vpi/vci
Configures a PVC on the ATM interface or
subinterface. All PVCs configured on the interface or
subinterface will inherit the VC class properties.
