enable watchdog

enable watchdog


Enables the system watchdog timer.

Syntax Description

This command has no arguments or variables.



Usage Guidelines

The watchdog timer monitors the health of the switch hardware and software events. For example, the watchdog timer reboots the switch if the system cannot reset the watchdog timer. This is caused by a long CPU processing loop, any unhandled exception, or a hardware problem with the communication channel to the watchdog. In most cases, if the watchdog timer expires, the switch captures the current CPU status and posts it to the console and the system log. In some cases, if the problem is so severe that the switch is unable to perform any action, the switch reboots without logging any system status information prior to reboot.

This command takes affect immediately.

The watchdog settings are saved in the configuration file.

To display the watchdog state of your system, use the show switch command.


The following command enables the watchdog timer:
