# vc-class atm

#### Syntax

[ no ] vc-class atm vcClassName

#### Release Information

Command introduced in JunosE Release 7.3.0.

#### Description

Creates and names a VC class for an ATM data PVC. This command accesses ATM VC Class Configuration mode, from which you can configure a set of attributes for an ATM data PVC. The VC class can include attributes for the service category, encapsulation method, F5 OAM options, and Inverse ARP. You then apply the attributes as a group by assigning the VC class to an individual PVC, to all PVCs created on a specified ATM major interface, to all PVCs created on a specified ATM 1483 subinterface, or to a base profile from which bulk-configured VC ranges are dynamically created. The no version removes the named VC class from the router.

You cannot remove a VC class that is currently assigned to at least one ATM PVC, ATM 1483 subinterface, or ATM major interface without first issuing the no class-vc command or the no show ip dhcp-local binding command to remove the VC class association with the PVC, interface, or subinterface.

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