Description

This menu allows to configure system 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, but 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.
