JUNOSe 11.1.x Link Layer Configuration Guide
The following commands, which are available only in ATM VC Configuration mode,
configure nondefault VC integrity and alarm surveillance parameters on a data PVC.
In this example, the VC integrity parameters configured with the oam retry command
include the up retry count (4), down retry count (6), and retry frequency (2). The
alarm surveillance parameters configured with the oam ais-rdi command include
the alarm down count (2) and alarm clear timeout duration (4 seconds). Issuing the
exit command causes the configuration to take effect.

Configuring Individual ATM PVC Parameters
host1(config-subif-atm-vc)#exit
host1(config-subif)#
host1(config)#interface atm 3/0.0
host1(config-subif)#pvc 32 0/32
host1(config-subif-atm-vc)#oam retry 4 6 2
host1(config-subif-atm-vc)#oam ais-rdi 2 4
host1(config-subif-atm-vc)#exit
host1(config-subif)#
Use to configure surveillance parameters for AIS and RDI F5 OAM fault
management cells on an ATM data PVC.
You can optionally specify the following values:
alarmDownCount Number of successive alarm cells, in the range 1–60, for
the router to receive before reporting that a PVC is down; the 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; the default value is 3
To configure these alarm surveillance parameters, you must use the oam ais-rdi
command in ATM VC Configuration mode. There is no equivalent atm pvc
command to configure these parameters.
You must issue the exit command from ATM VC Configuration mode for the
configuration to take effect.
Example
host1(config-subif-atm-vc)#oam ais-rdi 5 10
host1(config-subif-atm-vc)#exit
Use the no version to restore the default values for the alarm down count and
alarm clear timeout duration.
See oam ais-rdi.
Use to enable F5 OAM CC verification on an ATM data PVC.
You can optionally specify one of the following values to configure CC cell flows:
segment Opens an F5 OAM CC segment cell flow
end-to-end Opens an F5 OAM CC end-to-end cell flow
