Table 36: Alarm Terms and Definitions (continued)
DefinitionTerm
Alarms include the following types:
•
Chassis alarm—Predefined alarm triggered by a physical condition on the device 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 that might be triggered by a missing rescue configuration, failure
to install a license for a licensed software feature, or high disk usage.

Interface Alarm Messages
Interface alarms are alarms that you configure to alert you when an interface is down.
To configure an interface link-down condition to trigger a red or yellow alarm, or to configure the link-down
condition to be ignored, use the alarm statement at the [edit chassis] hierarchy level. You can specify the
ethernet, fibre-channel, or management-ethernet interface type.
NOTE: Fibre Channel alarms are only valid on QFX3500 devices.
NOTE: When red alarms or major alarms are issued on QFX5100 and EX4600 switches, the alarm
LED glows amber instead of red.
By default, major alarms are configured for interface link-down conditions on the control plane and
management network interfaces in a QFabric system. The link-down alarms indicate that connectivity to
the control plane network is down. You can configure these alarms to be ignored using the alarm statement
at the [edit chassis] hierarchy level.
NOTE: If you configure a yellow alarm on the QFX3008-I Interconnect device, it will be handled
as a red alarm.
