Displaying a Network Topology View
EPICenter Software Installation and User Guide 287
A Map is a collection of nodes and links.
The top portion of the left-hand panel displays the Map Hierarchy Tree. This starts at the root map and
shows the hierarchy of submaps in the current topology view. The current map name is highlighted.
The bottom portion of the left-hand panel is the Map Element Description panel, that displays
information about the currently selected map element if one (and only one) is selected. Otherwise, the
panel is empty.
The main panel displays the currently selected map in the current topology view. Only one view and
map can be displayed at a time.
Map Elements
The following elements can appear on a map:
Device Nodes. Device nodes represent the managed devices found in EPICenter’s Inventory data base.
Figure 134: Example of device nodes, including an unknown device type
A device node shows the following information:
• The name of the device as it is kept in the Inventory database (this can be hidden using View or Map
properties).
• An optional, user-supplied annotation for the node.
• A small icon representing the specific device or device product line, if the device is of a known type,
or an “unknown” device icon (a circle with a question mark) as shown in Figure 134. (This can be
hidden using View or Map properties.)
•
The device’s IP address.
• The device status, indicated by the color of the icon border.
— A green border indicates that the device is up.
— A red border indicates that the device is down.
Each managed device known to EPICenter can only appear once in each topological view.
Submap Nodes. A submap node represents a child map of the current map.
Figure 135: Example of a submap node
The submap node icon shows the following information:
• The name of the node (submap), which can be edited. By default, it is given the subnet
address/subnet mask as the name.
