12.6 Alarm management

12.6.1 Introduction

Alarm means when a fault is generated on the ISCOM2600G-HI series switch or some
working condition changes, the system will generate alarm according to different faults.
Alarm information is used to report some urgent and important events and notify them to the
network administrator promptly, which provides strong support for monitoring device
operation and diagnosing faults.
Alarm information is stored in the alarm buffer. Meanwhile, the alarm is generated to log
information. If a Network Management System (NMS), the alarm will be sent to network
management system through SNMP. The information sent to the NMS is called Trap
information.
