A hyper node icon shows the following information:
• The name of the device or cloud node that this hyper node represents (this can be hidden using
View or Map properties).
• An optional, user-supplied annotation for a device hyper node. This is a different annotation than
will appear in the device node that this hyper node represents.
• A hyper node icon, as shown in Figure 137.
• The device IP address, for a device hyper node.
• The device status, for a device hyper node, as 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
An L2 cloud hyper node does not show any status information.
NOTE
You cannot add, cut, or delete hyper nodes; they are placed and removed automatically by EPICenter
as required by device connectivity.
Decorative Nodes. A decorative map node can be created by the user to represent any other type of
node that is not discovered or managed by EPICenter, such as a server or workstation.
Figure 138: Example of a decorative node
A decorative node shows the following information:
• The name or description of the node, which can be edited
•
A decorative node icon, as shown in Figure 138. (This can be hidden using View or Map properties.)
Text Nodes. A text map node is a single-line text field that can be placed anywhere in a network map.
It can be used to create a title for the map, additional annotations for other map elements, comments,
and so on.
Links. A link represents connectivity between nodes in the map. Links can be automatically detected
on Extreme Networks devices with EDP enabled.
NOTE
For third-party devices or Extreme Networks devices with EDP disabled or not supported, you can
manually add links to the map to represent connectivity between devices. However, these links will
always have unknown status, will not display endpoint or utilization information, and will not be updated
when the map topology changes. The behavior of links described in the following paragraphs does not
apply to manually-added links.
When a discovered link connects two devices on the same map, the link will be annotated with the port
number, or slot and port number for each of the endpoints, as shown in Figure 139.
