Configuring VC Bundling with IP and ATM QoS
In the following example, the show running-config command displays the configuration for the VC
bundle:
Switch# show running-config interface atm11/0/0.1

Configuring VC Bundling with IP and ATM QoS
This section describes the ATM virtual circuit (VC) bundle management on the enha nced ATM Router
Module with IP/ATM QoS configured. The ATM VC bundle management feature allows you to
configure multiple VCs that have different QoS characteristics between any pair of ATM-connected
routers or Catalyst 8500 MSRs.
Note The VC-bundle feature is only applicable for enhanced ATM Router Modules installed in the
Catalyst 8540 MSR chassis.
The VC bundle management feature allows you to define an ATM VC bundle and add VCs to it as
needed. Each VC bundle has its own ATM traffic class and ATM traffic parameters, and you can apply
attributes and characteristics collectively at the VC bundle level.
Using VC bundles, you can create differentiated service by distributing IP precedence levels among the
different VC bundle members. You can then map a single precedence level or a range of levels to each
discrete VC in the bundle, thereby enabling individual VCs in the bundle to carry packets marked with
different precedence levels.
VC bundling with IP and ATM QoS has the same benefits and restrictions as VC bundling described in
the section, “Configuring VC Bundling”.
