Table 34: Alarm Terms and Definitions (continued)
Definition Term
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.
