If you create 2 links between the same 2 entities, IE 2 interface links exist between 2 Core Sw and Router, this displays in Orion maps as only 1 link. You have to click on the link to display both interfaces and statistics.
Additionally, the statistics displayed on this link display for only 1 of the 2 links, and I was told by SolarWinds displays the last populated data so switches between either of the interfaces. You cannot create a custom text field to statically display the data for both and/or aggerate of the 2. I opened Case # 00870318 with SolarWinds and was told this is a limitation of the map.
Additionally, if you add the individual interfaces to the map to display these links separately, it will still display the device-device links as an inherited topology connection and this cannot be removed. This is problematic because it could be displaying either of the 2 links and cant be defined.
Feature request to display 2 links between entities.
