Re: IMC 5.1 in Topology View had wrong connection



I don't have a definitive solution or an explanation of such issue, but alternatively you can manually delete the wrong links using the "Link Management" tool :


Open a custom topology and then click on the button LinkMgmtButton.JPG to open the Link Management tool.

Then a new window open in which you can manage (and so delete) some link (you can filter on some devices, interfaces ... using the query button) :



After having deleted some links, they appear as "deleted" link in the tool (so that you can manually recover them) :



Hope this helps,
