If the device has known links to other devices already on the map, or on other submaps within the
same view, those links will also be placed on the map. A hyper node may also be placed on the map, if
required for connectivity between the devices.
If all devices known to EPICenter are already placed in this view (on any of the maps in the view) the
pop-up window will inform you of that fact.
Hyper Nodes. You cannot add or remove hyper nodes to or from your map; they are added
automatically if the connectivity between device nodes requires it.
New Decorative Map Node
You can add a decorative node to your map by doing one of the following:
●
Select New Decorative Map Node from the New menu.
●
Right-click on the map background to display the pop-up menu, then select New Decorative Map
Node .
A decorative map node is a node that can be used to represent any component of your network that is
not recognized or managed by EPICenter.
You can change the node name by selecting the node, and editing the contents of the name field in the
Information panel. The change will take effect when you click away from the submap node.
New Text Map Node
You can add a text node to your map by doing one of the following:
●
Select New Text Map Node from the New menu.
●
Right click on the map background to display the pop-up menu, then select New Text Map Node .
A text map node can be used to annotate your map, such as to create a title for the map.
New User-Created Map Link
There may be situations where you want to represent a link between devices when a “real” link cannot
be detected by EPICenter. This may be the case if EDP and LLDP are disabled on an Extreme Networks
device, if a non-Extreme Networks device does not support LLDP, or if neither EDP or LLDP are
supported by the version of ExtremeWare running on the device. In these cases you can add a link
between nodes on your map by doing the following:
●
Select New User Created Map Link from the New menu.
A link terminated with red triangles is added to your map, as shown in Figure 140 .
For a user-created link, the endpoints in the link annotation are separated by an “x” rather than by a
dash “-”. For example, the link annotation “p1:1 - p24“ indicates a discovered link; the annotation “p1:1
x p24” indicates a user-created link.
The port annotations on a user-created link are initially shown as “
p? x p?
”. You can select each
endpoint and specify actual port numbers as appropriate. User-created map links can be used for links
to third-party devices that do not run LLDP, in order to display link status.
