JUNOSe 11.0.x Link Layer Configuration Guide

Assigning VC Classes to Individual PVCs

To assign a previously configured VC class to an individual ATM data PVC, you use
the class-vc command from ATM VC Configuration mode. Issuing this command
applies the set of attributes configured in the specified VC class to the ATM data PVC.
NOTE: The class-vc command is valid only for a data PVC created with the pvc
command. It has no effect for data PVCs created with the atm pvc command, or for
control (ILMI) PVCs. For information about creating a data PVC by using the pvc
command, see "Creating Data PVCs" on page 47.
For example, the following commands assign the VC class named
premium-subscriber-class to the ATM data PVC with VCD 2, VPI 0, and VCI 200.
For those attributes that you do not explicitly specify for the ATM PVC, the router
applies the values specified in the VC class. As explained in "Precedence Levels" on
page 56, the values in a VC class assigned to an individual PVC take precedence over
both of the following:
For examples that illustrate how precedence levels affect the assignment of VC
classes, see "Precedence Level Examples for Assigning VC Classes" on page 67.

Configuring ATM VC Classes
For information about the total number of VC classes supported on the router,
see JUNOSe Release Notes, Appendix A, System Maximums.
Example
host1(config)#vc-class atm dsl-subscriber-class
host1(config-vc-class)#exit
Use the no version to remove 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 class-int command to remove the VC class association with
the PVC, interface, or subinterface.
See vc-class atm.
! Assign VC class premium-subscriber-class to PVC 2/0.200
host1(config)#interface atm 2/0.200
host1(config-subif)#pvc 200 0/200
host1(config-subif-atm-vc)#class-vc premium-subscriber-class
host1(config-subif-atm-vc)#exit
Values in a VC class assigned to an ATM 1483 subinterface
Values in a VC class assigned to an ATM major interface
Use to assign a previously configured VC class to an individual ATM data PVC.
The class-vc command is valid only for data PVCs created with the pvc command.
