TABLE 1-3Properties Under watchdog-timerNode

Property	Values	Description

State	armed	Indicates timer is armed or running. Cleared by disarm.
	expired	Indicates timer has expired. Cleared by disarm.
	disarmed	Default value set at startup time. Indicates timer is disarmed or
		stopped.
WdTimeout*	Varies by system	Indicates the timer initial countdown value. Should be set prior
	and timer level	to arming the timer.
WdAction\	none	Default value. No action is taken.
	alarm	Sends notifications to system alarm hardware by means of
		HEALTHY#.
	reset	Performs a soft or hard reset of the system (implementation
		specific).
	reboot	Reboots the system.

*A platform might not support a specified timeout resolution. For example, Netra CT 810/410 systems only take -1, 0, and 100 to 6553500 msec in increments of 100 msec for level 1; and -1, 0, and 1000 to 255000 in increments of 1000 msec for level 2.

\A specific timer node might not support all action types. For example, Netra CT watchdog level 1 timer supports only none, alarm, and reboot actions. Watchdog level 2 timer supports only none and reset.

To identify current settings of watchdog-controller, issue the command prtpicl -vas shown in the sample output below.

#prtpicl -v
