I am going to try to explain some odd interface issues that I have form time to time.
1. I have network sonar configured on my Domains to auto import nodes in select OUs.
2. There are some morning that I come in and have a good handful of nodes that have new NIC cards in them even though nothing has changed.
3. Is there something I am missing from the network sonar that would be doing this? These are not new nodes but nodes that have been in Solarwinds the problem I am having is the old interfaces are showing up as Unknowns and causing issues with Orion.
