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 132: Example of a decorative node
A decorative node shows the following information:
●
The name or description of the node, which can be edited
Decorative nodes 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 are automatically detected on
Extreme Networks devices when EDP or LLDP is enabled on either device. Links can also be detected
on third-party devices that support LLDP. Links can also be user-created.
NOTE
For devices with EDP and/or LLDP disabled or not supported, you can manually add user-defined links to the map to
represent connectivity between devices. These links will initially have unknown status, will not display endpoint or
utilization information unless each endpoint is connected to an actual port. They are not updated when the map
topology changes. The behavior of the system-discovered links described in the following paragraphs does not apply
to user-defined 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 133 .
Figure 133: Example of a gigabit link showing endpoint connectivity and Up status
When one of the endpoints is within another submap, a hyper node is used to represent the device that
contains the endpoint within the submap.
NOTE
If there are more than 400 nodes on a map, link annotations are not displayed.
