#### Release Information

Command introduced in JunosE Release 7.1.0.
ATM VC Class Configuration mode added in JunosE Release 7.3.0.

#### Description

In ATM VC Configuration mode, enables F5 OAM continuity check (CC) verification on an ATM PVC. The oam cc command is valid only for data PVCs; you cannot use this command for control (ILMI or signaling) PVCs. The no version restores the default behavior, which disables F5 OAM CC verification and restores the default setting for cell termination, end-to-end.

In ATM VC Class Configuration mode, enables F5 OAM CC verification as part of a VC class definition that you assign to an ATM data PVC. The no version restores the default setting for cell termination, end-to-end, in the VC class.
