# oam-pvc

#### Syntax

oam-pvc [ manage ] [ loopbackFrequency ]

no oam-pvc [ manage ]

#### 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 generation of F5 OAM loopback cells on an ATM PVC and, optionally, enables F5 OAM VC integrity features that affect the operational state of the circuit. The oam-pvc command is valid only for data PVCs configured with aal5snap, aal5autoconfig, or aal5mux ip encapsulation; you cannot use this command for data PVCs with other encapsulation types or for control (ILMI or signaling) PVCs. The no version restores the default behavior, which disables F5 OAM VC integrity and restores the default value for loopback frequency.

In ATM VC Class Configuration mode, enables generation of F5 OAM loopback cells and, optionally, enables F5 OAM VC integrity features as part of a VC class definition that you assign to an ATM data PVC. The no version restores the default behavior, which disables F5 OAM VC integrity and restores the default loopback frequency, in the VC class.

#### Options

- manage—Enables F5 OAM VC integrity on the ATM PVC
- loopbackFrequency—Number of seconds, in the range 1–600, for the router to wait between the transmission of loopback cells during normal operation; default value is 10

#### Mode

ATM VC Configuration, ATM VC Class Configuration
