In our previous version 2.6, two devices that were connected to a non-Cisco switch would show up on a thick black backbone line, because CDP info was being forwarded through. Now in 3.1, they show up under the Unconnected Devices view. Their CDP neighbor info is correct on both, but the won't show up in the Layer 2 view. (See attachments) I've tried removing the devices down stream and running a collection job with no luck.
Has Cisco done away with this black backbone line in the new version? It's not a big deal, but it would be nice to be able to view everything on one view like before. Thanks.
