7.9.4 Reset Watchdog Timer Command
The Reset Watchdog Timer command is used for starting and restarting the Watchdog Timer
from the initial countdown value that was specified in the Set Watchdog Timer command.
If a pretime-out interrupt has been configured, the Reset Watchdog Timer command will not
restart the timer once the pretime-out interval has been reached. The only way to stop the
timer once it has reached this point is via the Set Watchdog Timer command.
7.9.5 Set Watchdog Timer Command
The Set Watchdog Timer command is used for initializing and configuring the watchdog timer.
The command is also used for stopping the timer.
If the timer is already running, the Set Watchdog Timer command stops the timer (unless the
“don’t stop” bit is set) and clears the Watchdog pretime-out interrupt flag (see Get Message
Flags command in the IPMI specification v1.5). IPMC hard resets, system hard resets, and the
Cold Reset command also stop the timer and clear the flag.
