Assigning VC Classes to Base Profiles for Bulk-Configured VC Ranges

To assign a VC class to a base profile for a dynamic ATM 1483 subinterface, you can
use the atm class-vc command from Profile Configuration mode. Issuing this
command applies the set of attributes in the specified VC class to all bulk-configured
VC ranges that are dynamically created from this profile.
For more information, see "Configuring ATM 1483 Dynamic Subinterfaces" on
page 628 in "Configuring Dynamic Interfaces Using Bulk Configuration" on page 623.

Precedence Level Examples for Assigning VC Classes

The examples in this section illustrate how the precedence level rules described in
"Precedence Levels" on page 56 affect the assignment of VC classes and PVC attribute
values.
For all of these examples, assume that you have issued the following commands to
configure a VC class named my-premium-class:
Example 1 and Example 2 illustrate the effect of precedence levels when you assign
the VC class my-premium-class to an individual PVC with VCD 200, VPI 0, and
VCI 200. Example 3 illustrates how using the atm pvc command affects VC class
assignment. Finally, Example 4 illustrates how modifications to a VC class affect PVC
attributes applied through RADIUS.

Example 1: Explicitly Changing the Service Category

Explicitly specified attribute values take precedence over attribute values specified
in a VC class. As a result, the following commands cause the router to use the most
recent explicitly specified value, UBR with a PCR of 200 Kbps, as the service category
for this PVC instead of the service category specified in my-premium-class, CBR with
a PCR of 200 Kbps. The router takes the values for the other attributes from the VC
class my-premium-class.
systemwide default values, or to the values set in the associated VC class with
the next highest order of precedence.
