For more information about OAM parameters, see “Operations, Administration, and
Management of ATM Interfaces” on page 14.
NOTE: The oam-ais rdi command and the oam retry command are available only in
ATM VC Configuration mode. There is no equivalent atm pvc command to configure
these F5 OAM alarm surveillance and VC integrity parameters.
For example, the following commands enable VC integrity on a data PVC with a nondefault
loopback frequency (30 seconds). Issuing the
exit command causes the configuration
to take effect.
host1(config)# interface atm 3/0.0
host1(config-subif)# pvc 32 0/32
host1(config-subif-atm-vc)# oam-pvc manage 30
host1(config-subif-atm-vc)# exit
host1(config-subif)#
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.
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)#
oam ais-rdi
•
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.
