Currently the Network Map will draw multiple links between devices and ports, overlapping themselves on the graph. The criteria used to select the link is also unspecified. Instead only allow a single link between any two devices/ports. Also prefer links with shorter names, and for links derived using arp/mac, prioritise links with a matching ip address.
