Understanding Alarms
QFX Series products support different alarm types and severity
levels. Table 1 provides a list
of alarm terms and definitions that may help you in monitoring the
switch.
Table 1: Alarm Terms and Definitions
Term | Definition |
|---|
Alarm | Signal alerting you to conditions that might prevent
normal operation. On the switch, alarm indicators include the LCD
panel and LEDs on the front. The LCD panel displays the chassis alarm
message count. Blinking amber LEDs indicate yellow alarm conditions
for chassis components. |
Alarm condition | Failure event that triggers an alarm. |
Alarm severity levels | Seriousness of the alarm. The level of severity can be
either major (red) or minor (yellow). - Major (red)—Indicates a critical situation on the
switch 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 switch 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.
|
Alarm types | Alarms include the following types: - Chassis alarm—Predefined alarm triggered by a physical
condition on the switch such as a power supply failure or excessive
component temperature.
- Interface alarm—Alarm you configure to alert you
when an interface link is down. Applies to ethernet, fibre-channel, and management-ethernet interfaces.
You can configure a red (major) or yellow (minor) alarm for the link-down
condition, or have the condition ignored.
- System alarm—Predefined alarm triggered by a missing
rescue configuration or failure to install a license for a licensed
software feature.
