Understanding Alarms
The QFX Series and OCX Series support different alarm types and severity levels.
Table 33 on page 155 provides a list of alarm terms and definitions that may help you in
monitoring the device.

Seriousness of the alarm. The level of severity can be either major (red) or minor (yellow).
•
Major (red)—Indicates a critical situation on the device that has resulted from one of the following
conditions. A red alarm condition requires immediate action.
•
One or more hardware components have failed.
•
One or more hardware components have exceeded temperature thresholds.
•
An alarm condition configured on an interface has triggered a critical warning.
•
Minor (yellow or amber)—Indicates a noncritical condition on the device that, if left unchecked, might
cause an interruption in service or degradation in performance. A yellow alarm condition requires
monitoring or maintenance. For example, a missing rescue configuration generates a yellow system
alarm.
