4.2.5 Ping Watchdog
System Configuration -> Ping Watchdog
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 all Router BOARD PowerPC which can reboot the
system in any case.
