Why do we need fault management ? • To monitor the network and know what’s going on ? • To identify the root cause of network faults ? • To measure downtime (uptime) ? • To meet SLA’s ? • Because everybody else does it ? • Because I’ve been told it’s important ? Presentation_ID © 2003 Cisco Systems, Inc. All rights reserved. 44

Fault Management • [ISO Definition] Handling errors, faults and alarms in a timely and controlled manner. Error: Deviation of system from normal operations Fault: Physical or algorithmic cause of a malfunction Alarm: Notification of a specific event, may or may not represent an error • A fault is an unplanned failure of software, hardware, or wetware • Not every outage is due to a fault • Not every fault results in an outage Presentation_ID © 2003 Cisco Systems, Inc.
