Summary
Sub-menu: /system watchdog
This menu allows configuring system to reboot, when a specific IP address does not respond, or when it detects, that the software has locked up. The detection is done in two ways:
- Software watchdog timer (mostly caused by hardware malfunction) device can recover itself with a reboot;
- Ping watchdog can monitor connectivity to a specific IP address and trigger reboot function;
