no oam ais-rdi

#### 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, configures surveillance parameters for alarm indication signal (AIS) and remote defect indication (RDI) F5 OAM fault management cells on an ATM PVC. The oam ais-rdi 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 alarm surveillance and restores the default values for alarm down count and alarm clear timeout duration.

In ATM VC Class Configuration mode, configures alarm surveillance parameters for AIS and RDI F5 OAM cells 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 alarm surveillance and restores the default values for alarm down count and alarm clear timeout duration, in the VC class.

| Note: To configure the alarm down count and alarm clear timeout F5 OAM surveillance parameters, you must use the oam ais-rdi command. There is no equivalent atm pvc command to configure these parameters.

#### Options

- alarmDownCount—Number of successive alarm cells, in the range 1–60, for the router to receive before reporting that a PVC is down; default value is 1
- alarmClearTimeout—Number of seconds, in the range 3–60, for the router to wait before reporting that a PVC is up after the PVC has stopped receiving alarm cells; default value is 3

#### Mode

ATM VC Configuration, ATM VC Class Configuration
