no class-vc [ vcClassName ]
Command introduced in JUNOSe Release 7.3.0.
Assigns 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; it has no effect for data PVCs created with the atm pvc command, or for control (ILMI or signaling) PVCs. Issuing this command applies the set of attributes in the specified VC class to the ATM data PVC. The no version removes the VC class association with the ATM PVC.
