Display the Current Router Alarms

Action

To display the current router component alarms, use the following CLI command:

user@host> show chassis alarms

The command output displays the number of alarms currently active, the time when the alarm began, the severity level, and an alarm description. Note the date and time of an alarm so that you can correlate it with error messages in the messages system log file.

Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 20 through Table 27 list the alarms that the chassis components can generate.

Table 20 lists the alarms that the chassis components can generate on an M5 or M10 router.

Table 20: M5 or M10 Router Chassis Component Alarm Conditions

Chassis Component	Alarm Condition	Remedy	Alarm Severity
Alternative media	The router boots from alternate boot device: the hard disk. Typically, the router boots from the flash drive. If you configure your router to boot from the hard disk, ignore this alarm condition.	For technical support, open a support case using the Case Manager link at http://www.juniper.net /support/ or call 1-888-314-JTAC (within the United States) or 1-408-745-9500 (outside the United States).
