Creating/Editing a Custom Report. Clicking "add interface filter".
I can type in the IP and pick the interface wanted. This will work fine one or two times, but eventually instead of returning the correct interfaces under the device, NFA will return a non-expandable list of interfaces with no "Selection" boxes and containing random interfaces not under this IP address.
The problem happens if you go into "Add Interface Filter", then "Advanced Search", then search for an IP address, then expand the list of interfaces, then (with the list of interfaces still expanded) search for another IP address.
This is a known defect (DE364215) that is scheduled to be fixed in the the next release of NFA 10.0
Hit "Contract All" to do a search when the existing list of interfaces is not expanded. If you do that, the problem will not occur.
