Chapter 19 Configuring Quality of Service for PVC Bundles
Usage Guidelines for the oam-bundle Command
This command defines whether a VC bundle is OAM managed. If this command is configured for a
bundle, every VC member of the bundle is OAM managed. If OAM management is enabled, further
control of OAM management is configured using the oam retry command.
This command has no effect if the VC class that contains the command is attached to a standalone VC;
that is, if the VC is not a bundle member. In this case, the attributes are ignored by the VC.
To use this command in VC-class configuration mode, first enter the vc-class atm global configuration
command.
To use this command in bundle configuration mode, enter the bundle subinterface configuration
command to create the bundle or to specify an existing bundle before you enter this command.
VCs in a VC bundle are subject to the following configuration inheritance rules (listed in order of
next-highest precedence):

precedence Command

To configure precedence levels for a virtual circuit (VC) class that can be assigned to a VC bundle and
thus applied to all VC members of that bundle, use the precedence command in vc-class configuration
mode. To remove the precedence levels from the VC class, use the no form of the command.
To configure the precedence levels for a VC or permanent virtual circuit (PVC) member of a bundle, use
the precedence command in bundle-vc configuration mode for ATM VC bundle members. To remove
the precedence levels from the VC or PVC, use the no form of the command.
