System alarms
Alarms alert you to conditions that might prevent normal device operation:
● Critical — A critical condition exists and requires immediate action. A critical alarm may trigger if one or more hardware
components have failed, or one or more hardware components exceeds temperature thresholds.
● Major — A major error occurred and requires escalation or notification. For example, a major alarm may trigger if an
interface failure occurs, such as a port-channel being down.
● Minor — A minor error or non-critical condition occurred that, if left unchecked, might cause system service interruption or
performance degradation. A minor alarm requires monitoring or maintenance.
● Informational — An informational error occurred but does not impact performance. Monitor an informational alarm until the
condition changes.
Triggered alarms are in one of these states:
● Active — Alarms that are current and not cleared.
● Cleared — Alarms that are resolved and the device has returned to normal operation.
