Chapter 2 Basic Concepts
What Are the General Features of Cisco MGM?
2.3.2 Understanding Fault Management
Fault management enables the network administrator to avoid catastrophic conditions through alarms
and early warnings. The primary basis for fault management is provided by real-time messages (traps)
generated by network elements when a change in status occurs.
The fault management tools for Cisco MGM are described in Table 2-11.
Performance
management
Gathers and reports the behavior of NEs, network, and services, including
quality assurance, monitoring, management control, and analysis.
Performance management can be performed in the Configuration Center or in
the Statistics Report.
Chapter 10, “Managing
Performance”
Security
management
Prevents and detects any improper use of network resources and services as
well as recovery from security violations. Aspects of security management
include prevention, detection, containment, and recovery.

Security”

Function Description For More Information, See
Table 2-11 Fault Management Tools
Name Description
Alarm Management Identifies network problems and failures by using alarm management. For more information, see
Chapter 9, “Managing Faults.”
Device Management
with Chassis View
Provides a graphical view of equipment status for the operational and alarm status of each card, port,
line, or trunk, which is represented with a predefined color.
For more information, see 2.3.3.2 Managing Devices with Chassis View, page 2-18.
Diagnostic Center Generates real-time displays of element performance and utilization using system counters repeatedly
polled with SNMP, and facilitates the monitoring of activity and error rates of individual ports, lines,
and trunks.
By periodically polling each network element through SNMP, real-time counters detect and display
hardware failures at the card, interface, port, line, and trunk level.
Monitors statistics events to identify problems with Cisco MGM to effectively manage the network.
For more information, see section 2.3.6 Using the Diagnostic Center, page 2-25.
Alarm Browser Displays standing alarms and conditions in the managed domain. The Alarm Browser window lists the
conditions that are assigned a severity level of critical, major, minor, or warning. It also shows cleared
alarms that are not acknowledged.
For more information, see Chapter 9, “Managing Faults.”
Alarm Log The Alarm Log window contains alarms that have transitioned from the Alarm Browser. Cleared
alarms are transitioned when you acknowledge them or when automatic acknowledgment has been
enabled (in the Control Panel > User Interface Properties pane). In addition, the Alarm Log shows a
history of cleared and acknowledged alarms and all transient conditions (also known as events or
autonomous nonalarmed messages).
For more information, see Chapter 9, “Managing Faults.”
Dashboard The Cisco MGM Dashboard shows useful alarm and NE information in one easily accessible location.
