Cisco Cisco IOS Software Release 12.0(23)S

Bundle-level parameters can be applied either by assigning VC classes or by directly applying them to 
the bundle.

Parameters applied through a VC class assigned to the bundle are superseded by those applied at the 
bundle level. Bundle-level parameters are superseded by parameters applied to an individual VC.

Configuring bundle-level parameters is optional if a class is attached to the bundle to configure it.

To configure parameters that apply to the bundle and all its members, use the following commands in 
bundle configuration mode, as needed:

Use of a VC class allows you to configure a bundle by applying multiple attributes to it at the same time 
because you apply the class itself to the bundle. Use of a VC class allows you to generalize a parameter 
across all VCs, after which (for some parameters) you can modify that parameter for individual VCs. 
(See the section 

 for more information.)

To configure a VC class to contain commands that configure VC members of a bundle when the class is 
applied to that bundle, use the following command in vc-class configuration mode. To enter vc-class 
configuration mode, use the vc-class atm command.

In addition to the oam-bundle command, you can add the following commands to a VC class to be used 
to configure a bundle: bump, precedence, mpls experimental, and protect commands. For more 
information about these commands, see the 

 section, later in this publication.

Router(config-if-atm-bundle)# protocol protocol 

{protocol-address | inarp} [[no] broadcast]

Configures a static map or enables Inverse Address Resolution 
(Inverse ARP) or Inverse ARP broadcasts for the bundle

Router(config-if-atm-bundle)# encapsulation 

Configures the ATM adaptation layer (AAL) and encapsulation 
type for the bundle.

Router(config-if-atm-bundle)# inarp minutes

Configures the Inverse ARP time period for all VC bundle 
members.

Router(config-if-atm-bundle)# broadcast

Enables broadcast forwarding for all VC bundle members.

Router(config-if-atm-bundle)# ilmi manage

Enables ILMI management.

Router(config-if-atm-bundle)# oam retry 

[up-count] [down-count] [retry-frequency]

Configures the VC bundle parameters related to operation, 
administration, and maintenance (OAM) management.

Router(config-if-atm-bundle)# oam-bundle [manage] 

[frequency]

Enables end-to-end F5 OAM loopback cell generation and OAM 
management for all VCs in the bundle.

Router(config-vc-class)# oam-bundle [manage] 

[frequency]

Enables end-to-end F5 OAM loopback cell generation and OAM 
management for all VCs in the bundle.
