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: Whenred alarms or majoralarmsareissued 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 yellowalarmon the QFX3008-I Interconnectdevice,
it will be handled as a red alarm.
