Manual:System/Watchdog

Applies to RouterOS: v3, v4 +

Summary

This menu allows to configure 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.

Note: These are two different Watchdog features and both have their own settings. By default software Watchdog is enabled and ping Watchdog is disabled. You can enable ping Watchdog by specifying an IP address and you can disable software Watchdog by unsetting Watchdog Timer option.

Properties
