Back to my first email message when I thought you were already using 
OpenNMS...  You have to uncomment the Linkd service in 
etc/service-configuration.xml, then restart opennms and give it some 
time to probe.  Then it should show from the 'View Node Link Detailed 
Info' at the top left of a node page.  The weakest part of the program 
is the web admin section.  While it does a lot, there is much more that 
you can control via the xml config files.
