Creating A Vc Class - Cisco 10000 Series Configuration Manual

Chapter 1 4-Port OC-3/STM-1 ATM Line Card Configuration

Creating a VC Class

This procedure demonstrates how to create an ATM VC class. An ATM VC class is a PVC boilerplate—a
PVC description that you can apply to one or more PVCs.
To create a PVC boilerplate:
Use the global configuration mode vc-class atm name command, where name is the name value you
Step 1
assign. The following example shows how to create the
ATM VC class named boston.
Router(config)# vc-class atm boston
Router(config-vc-class)#
Enter commands to describe the ATM VC class you named boston. This example shows how to specify
Step 2
that the boston class uses AAL5+MUX encapsulation with a variable bit-rate non real-time (VBR-NRT)
PVC.
Router(config-vc-class)# encaps aal5mux ip
Router(config-vc-class)# vbr-nrt 30000 20000 128
Router(config-vc-class)# exit
Router(config)#
You have created a VC class named boston. The next procedure describes how to apply this class to a
PVC or subinterface.
Applying a VC Class
You can apply a VC class (created in the previous procedure) to a PVC or an interface.

You have completed the steps for assigning a VC class to a PVC.
Enabling ILMI PVC Discovery
You can enable ILMI to automatically discover PVCs on neighboring switches and duplicate those PVC
entries on the 4-Port OC-3/STM-1 ATM line card.

In the following example, the class named boston is applied to subinterface 5/0/0.1.
Router(config)# interface atm 5/0/0.1
Router(config-subif)# class-int boston
Router(config-subif)#
In the following example, the class named boston is applied to a new PVC (0/102) in subinterface
5/0/0.2.
Router(config)# interface atm 5/0/0.2
Router(config-subif)# pvc 0/102
Router(config-if-atm-vc)# class-vc boston
Router(config-if-atm-vc)#
