watchdog (PSM)

Syntax

Hierarchy Level

Description

Enable the power supply module (PSM) watchdog feature. Generally, Junos detects the thermal event health events and takes the required action as per user configuration. However, if a thermal health event causes Junos to go down, the PSM watchdog feature detects it and shuts down the router.

Note:

The PSM watchdog feature works only if all the online PSMs in the router support the feature.

Options

timeout value

Specify the watchdog timer in seconds. After the specified duration, the watchdog expires.

Range: 600 through 900 seconds
Default: 900 seconds

On Junos OS, timeout value is not significant since this value is programmed to watchdog reset counter. Instead, you can use the shutdown-timer option while configuring the thermal-health check feature.

pat-frequency value

Specify the frequency (in minutes) at which the software resets the watchdog counter. If the watchdog counter doesn’t get reset because of reasons such as Routing Engine crash and system reboot, on watchdog timer expiry, the PSM turns off the output power.

Range: 1 through 3 minutes
Default: 1 minute
