Laying Out The Map; Creating User-Defined Links - Extreme Networks Ridgeline Guide Manual

alarm icon (small bell). The alarm status shows the highest level alarm currently unacknowledged for
the device. The color of the bell indicates the severity of the alarm.
You can also specify how information is displayed for the devices on the map. Each kind of device
information (alarm status, device name, IP address, device annotation) can be shown with the device
icon at all zoom levels, not at all, or at relevant zoom levels. Showing the information at relevant zoom
levels (the default) means that each type of device information is shown at some zoom levels of the
map, and not at others. For example, by default a device's IP address or alarm status is shown at zoom
level 4 and below; a device's name and annotation is shown at zoom level 3 or below.
In the Background Image section, you can specify the filename of a graphic to be used as a background
image on the map. Ridgeline includes a number of sample background images, and you can add your
own. To add an image to the list of available background images, place it in the
directory.
<Ridgeline_install_dir>/extreme.war/gifs/topologyBackgroundImages
In the Link Label section, you can indicate the text caption that appears on links. This can be either the
port numbers (for example, p1-p2), or the port number with the port name in parentheses.
In the Appearance section, you can specify the size of the text used in the captions for the map title,
objects, and links, as well as the background color of the map.
After specifying properties for the map, click Save changes to apply the new properties and close the
window. Click Restore global map settings to reset the map properties to the globally set values.

Laying Out the Map

You can drag map nodes around on the map yourself, or you can have Ridgeline lay out the map nodes
for you. To have Ridgeline do the map layout, select Auto layout from the Map menu.
The Auto layout function calculates a default map layout, optimizing for node and link placement to
minimize overlap. If necessary, Ridgeline may create a layout that is larger than the visible window
area. In this case, scroll bars allow you to view different parts of the map.

Creating User-Defined Links

Links represent connectivity between nodes in the map. When a map is created, 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.
In addition to the automatically detected links, you can manually define your own links. This can be
useful in situations where you want to represent a link between devices when a "real" link cannot be
detected by Ridgeline. 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 software running on the device.
On the map display, the endpoints of a user-defined link are separated by an "x" rather than by a dash
"-". For example, the link annotation "p1:1 - p24"indicates an automatically detected link; the
annotation "p1:1 x p24" indicates a user-defined link.
