Chassis Alarm Messages
Chassis alarms indicate a failure on the device or one of its components. Chassis alarms are preset and cannot be modified.
Chassis alarms on QFX5100, QFX5110, QFX5210, and QFX5120 devices have two severity levels:
Major (red)—Indicates a critical situation on the device that has resulted from one of the conditions described in Table 1. A red alarm condition requires immediate action.
Minor (yellow)—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.
Table 1 describes the chassis alarm messages on QFX5100, QFX5110, QFX5200, QFX5210, and QFX5120 devices.
