Chapter 2 Basic Concepts
How Do I Navigate within Cisco MGM?
After zooming in on a region on the map, scroll bars at the bottom and right side of the screen allow you
to pan the view to a different region. You can also use the focus box in the top left panel to pan and zoom
the view. All groups are shown on a single map, and it is the zoom level and pan position that determine
what groups are visible at any time. Depending on the selected layer rate, certain NEs are shown. You
can open multiple map windows to compare different views.
Note Sometimes one node can overlap another in the maps. This occurs when a new node is added and other
existing nodes have already been assigned a location. The solution is to change the layout to make sure
that no two nodes are overlapping.
All groups, NEs, and labels are zoomed when you zoom in or zoom out. Cisco MGM allows you to save
the zoom level and framing of the map. Also, you can specify a fixed pixel size for icons so that
regardless of the zoom level, the map icon size does not change. By default, the icon size is variable
based on the zoom level. The icon size setting is saved with the other map settings.
When you open the Network Map from an NE in the Domain Explorer, the selected NE is centered on
the map.
Note The Refresh Data tool in the Network Map toolbar flashes when updates are available.
The following scenarios describe the actions of the Refresh Data tool in the Network Map toolbar.
• The Refresh Data tool flashes when:
– The map background is changed
– The topology structure changes (a node is added or deleted) in a group or area
– A node is forced invalid
• The Refresh Data tool does not flash when:
– The alarm counts change on the node
– The node connectivity state changes
– The node admin state changes
– The node name changes
– The node data properties change
– The discovery state changes
– The data reference changes
2.1.4 Using Control Panel
Most client and server configuration parameters are viewed and modified in the Control Panel window.
To view the Control Panel, choose Administration > Control Panel in the Domain Explorer. The left
side of the window displays the tree, which contains the following Cisco MGM functions and services:
• UI Properties—for Fault Management and Domain Management

Inactivity Timer Settings
