Appendix C: Alarm Definition
----------------------------
SNMP allows a northbound monitoring system (NOC) to receive
notifications in the form of traps or informs in response to events,
threshold violations, whatever the trap definitions in the loaded MIBs
are. Notifications are categorised at three levels (INFORM, WARNING,
ERROR) and the NBI may be set to report at a certain level or above. The
following event notifications are reported by NBI.
