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.
