To hook up or patch cables, either select the matching function in the context menu (right click) of a port, or by returning to the Dashboard (1) and selecting the needed function (3&4) in the Cable Management section (2).
When hooking up a cable, first choose source and target ports. Use >> to copy information from source to target.
After clicking Next select a cable and a line definition, as well as the desired naming rule. Lastly click Complete to hook up the cable.
Patching works similarly in the corresponding dialog.
