show atm bundle
This example is the output of an ATM bundle configuration. In this example, you will note that:
·
IP Precedence 5 (voice) is assigned to the 256 kbps Voice PVC (0/600).
·
All other precedence values are assigned to the 512 kbps Data PVC (0/60).

show policy interface atm
This example is the output of an ATM interface policy configuration. In this example, you will note that:
·
The service policy is only applied to the data VC.

This example is the output of an ATM VC configuration. In this example, you will note that:
·
Voice gets VBR.
·
