Interface Alarm Messages
Interface alarms are alarms that you configure to alert you when an interface is down.
By default, interface alarms are not configured.
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.
