You cannot add L2 cloud nodes; they are placed automatically by EPICenter as
required by device connectivity. You can remove them, but they may be replaced
automatically by EPICenter if still needed.
Hyper Nodes: A hyper node represents a link termination when the actual terminating
node (device or cloud) is present on another map. Thus, a hyper node will show the same
information as the node it represents (except for the optional node annotation):
Figure 12-5: Example of hyper node icons representing a device and an L2 cloud
A hyper node icon shows the following information:
• The name of the device or cloud node that this hyper node represents
• 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 12-5
• The device IP address, for a device hyper node
• Thedevice 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.
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.
