Cisco Cisco IOS Software Release 12.0(23)S

To configure a virtual circuit (VC) bundle with the bundle-level commands contained in the specified 
VC class, use the class-bundle bundle configuration command. To remove the VC class parameters from 
a VC bundle, use the no form of this command.

class-bundle vc-class-name

no class-bundle vc-class-name

No VC class is assigned to the VC bundle. 

Bundle configuration

To use this command, you must first enter the bundle command to create the bundle and enter bundle 
configuration mode.

Use this command to assign a previously defined set of parameters (defined in a VC class) to an ATM 
VC bundle. Parameters set through bundle-level commands contained in a VC class are applied to the 
bundle and its VC members.

You can add the following commands to a VC class to be used to configure a VC bundle: oam-bundle, 
broadcast, encapsulation, protocol, oam retry, and inarp.

Bundle-level parameters applied through commands configured directly on a bundle supersede 
bundle-level parameters applied through a VC class by the class-bundle command. Some bundle-level 
parameters applied through a VC class or directly to the bundle can be superseded by commands that 
you directly apply to individual VCs in bundle-vc configuration mode.

In the following example, a class called class1 is first created and then applied to the bundle called 
bundle1:

! The following commands create the class class1:

vc-class atm class1

encapsulation aal5snap

broadcast

protocol ip inarp

oam-bundle manage 3

Name of the VC class you are assigning to your VC bundle.

12.0(23)S

This command was made available in bundle configuration mode on the 
8-Port OC-3 STM-1 ATM line card for Cisco 12000 Series Internet Routers.
