To troubleshoot, go into the respective devices and execute "show cdp neighbors" commands.
If the devices all see each other as neighbors, the problem is in CW's interaction with the devices. If that is the case, make sure each device's credentials are allowing CW to correctly query it.
If not, then fix the cdp interaction on the devices and rediscover and then recheck CW's network view.
Hope this helps. Please rate helpful posts.
