Hi,I created a 'patchpanel' branch. It adds support for linking ports multiple times and tracing cable paths. Several people have created patches for this already. Most of them handle some, but not all, possible use cases.
Further details can be found here: https://github.com/RackTables/racktables/blob/patchpanel/README.patchpanel
Please test it out and provide feeback on the mailing list or on the related Mantis ticket: http://bugs.racktables.org/view.php?id=333
Thanks. -- Aaron Dummer
