Chapter 2 Basic Concepts
What Are the General Features of Cisco MGM?
2.3.2.1 Defining Events and Alarms
Events and alarms are different with the following requirements:
• Events are network-generated entities that do not have any state or duration.
• Alarms are Cisco MGM generated entities that do have state and duration.
• Alarms and states are changed based on Cisco MGM receiving certain events.
• Only a subset of all events results in alarm state changes.
2.3.3 Understanding Configuration Management
Note For detailed information on configuration management, see Chapter 6, “Configuring Hardware.”
Configuration management in Cisco MGM includes both the configuration of individual network
elements at the port and line level, and the provisioning of user services, for example, network elements
and connections.
These topics describe configuration management for Cisco MGM:
• 2.3.3.1 Configuration Center Overview, page 2-17
• 2.3.3.2 Managing Devices with Chassis View, page 2-18
• 2.3.3.3 Understanding Inventory Management, page 2-18
• 2.3.3.4 NE Release Management, page 2-19
2.3.3.1 Configuration Center Overview
The Configuration Center enables internal chassis connection configurations into one application.
The Configuration Center window has three main areas:
• Hierarchy Pane—Displays the network hierarchy as a tree of objects with real-time alarms. The tree
is used to navigate the networks from the network level down to the port level.
• Configuration Pane—Displays the elements of the selected object. If an object is not selected, the
configuration window is empty.
