Hardware Watchdog Management
Home menu level: /system watchdog
Description
This menu allows to configure system to reboot on kernel panic, when an IP address does not
respond, or in case the system has locked up. Software watchdog timer is used to provide the last
option, so in very rare cases (caused by hardware malfunction) it can lock up by itself. There is a
hardware watchdog device available in RouterBOARD hardware, which can reboot the system in
any case.
Property Description
reboot-on-failure ( yes | no ; default: no ) - whether to reboot on kernel panic
watch-address ( IP address ; default: none ) - if set, the system will reboot in case 6 sequental
pings to the given IP address (sent once per 10 seconds) will fail
• none - disable this option
watchdog-timer ( yes | no ; default: no ) - whether to reboot if system is unresponsive for a minute
