Troubleshooting

Topology

Problem: In Map Properties, changed the node background color, but only some of the node
backgrounds changed.
The background color affects submap nodes, device hyper nodes and device or decorative nodes that do
not display the device icon (either because the icon display is turned off or the nodes have been
reduced in size to where the icon cannot be displayed). For device nodes and decorative nodes with the
device icon displayed, the background color is transparent, and the background color setting is ignored.
Problem: A link has been moved, but the old link still appears as a down or unknown link.
When a previously "up" link disappears, the EPICenter server cannot tell if whether it is down or has
been physically moved, so it changes its status to down (or unknown). EPICenter will detect the new
link and add it as an up link, but it will not remove the old link.
To remove non-existent links, you can use the Sync Links command in the Topology applet. This
command will remove all down links. Note that this command will also remove existing links that are
down, but EPICenter will rediscover and add back those links when they come back up.
Problem: The Sync Links command removed legitimate links that were down.
The EPICenter server cannot discover a link if the link is down. Therefore, when it rediscovers links it
will only discover up links (or partially up links in the case of composite links). However, down links
will automatically reappear when they come up again. You can also use the Sync Links command again
after the down links have come back up.

STP Monitor

Problem: There are multiple STP nodes with the same name.
The EPICenter server identifies an STP domain by its name and tag. If you see multiple STP domains in
EPICenter, you may have a misconfiguration where the same STP domains are configured with
different tags on different switches.

Reports

Problem: After viewing reports, added a user-defined report, but it doesn't appear in the list of
reports on the main reports page.
The Reports page updates the list of reports when the page is loaded. To update the list, Refresh the
page.
Problem: Reports cannot be launched.
Due to a problem with Windows, sometimes reports cannot be launched from the EPICenter client. To
work around this problem, you can either set your browser home page to blank, or you can run the
Reports feature directly from the browser:
1 Point the browser to the URL of the EPICenter server:
http://<host>:<port>/
