This forum post (https://www.netxms.org/forum/configuration/network-map-dual-link-on-same-object) suggests that it should be possible - multiple links are created and bend point routing needs to be used so the links shape can be changed. It does not work for me - I am unable to add second link between two objects in 1.2.14, web console.

Is it a bug or feature?
