Configuring ATM VC Classes

As an alternative to configuring individual parameters for ATM data PVCs, you can access ATM VC Class Configuration mode to configure a class of attributes for an ATM data PVC. A VC class is a set of attributes for a virtual circuit (VC) that can include the service category, encapsulation method, F5 OAM options, and Inverse ARP.

After you configure the VC class, you then apply the attributes in the class as a group by assigning the VC class to one of the following:

An individual PVC
All PVCs created on a specified static ATM major interface
All PVCs created on a specified static ATM 1483 subinterface
A base profile from which bulk-configured VC ranges are created on a dynamic ATM 1483 subinterface

VC class assignments are valid only for ATM data PVCs created with the pvc command. Assigning a VC class to a PVC created with the atm pvc command, or to a control (ILMI) PVC, has no effect. For information about creating a data PVC by using the pvc command, see Creating Data PVCs.

Note: For information about the total number of VC classes supported on the router, see JUNOSe Release Notes, Appendix A, System Maximums.
