Bill, Thanks for the clue. I was able to track down the devices that creates the anonymous networks when polled with a Command-K. It's my SonicWALL firewalls. I get an anonymous network for each SonicWALL on the map when I do a Command-K for the entire map. I did some tests on my primary SonicWALL and this is what I discovered.
The anonymous network circles are orphaned immediately, NOT after a second poll. I select the SonicWALL, hit Command-K, and IM creates a little circle in the middle of the screen, then draws a thin dotted line from the SonicWALL to the circle. Then it instantly erases the dotted line, leaving the circle behind. I created a new map and added the SonicWALL's IP. IM auto-detected the device as a router, and drew it on the map with a single network circle connected to it via a dotted line. Pressing on the line shows me that IM thinks it's a link with unknown speed. Pressing on the circle says it's IP network 192.168.10.1/2*, which is the right IP address for the SonicWALL's LAN port but the wrong subnet (which is supposed to be /24). Hitting Command-K repeatedly at this point does NOT add more circles. However, if I check the "Display unnumbered interfaces" checkbox (or change the device type to Switch which does the same thing), four more numbered circles show up, and the original dotted line goes away, leaving the original network circle orphaned. (The numbered circles correctly correspond to the three physical Ethernet interfaces and the loopback interface.) At this point, Command-K causes IM to create a new network circle that's momentarily connected to the SonicWALL with a dotted line. If I then go back and uncheck "Display unnumbered interfaces", surprisingly, Command-K still continues to create more circles. This behavior apparently began with the 4.1.2 update. I'll be glad to provide any other troubleshooting information you might need. Later, Doug -- Doug Weathers, Network Administrator St. Charles Medical Center >>> [EMAIL PROTECTED] 1/8/2004 7:02:43 AM >>> Doug: When you notice that 'anonymous networks' are appearing, it means that InterMapper is encountering a transient interface on a device (or devices). Here's how it is supposed to work: InterMapper discovers a new IP address on a box associated with some ifIndex, so IM creates a link to a new network to represent the new subnet. On the next scan of the device's static configuration (if you don't cmd-K, this will take place 6 hours later), InterMapper determines that the IP address is no longer there, so the link to the new network is removed, and the network becomes anonymous. (Note that the 'network' gets its 'subnet numbers' from the adjacent links. If the link goes away, the subnets go away, but the network remains. I'm terming this anonymous because it is both unnumbered *and* isolated.) InterMapper does not remove the anonymous networks for you; you can select them in edit mode and press Backspace. InterMapper's current implementation will never reuse them. In an earlier version (several years ago), we did remove the anonymous networks for you, but this didn't prevent transient interfaces from causing confusion. With that background, I have seen our "Snow Apple Airport" cause anonymous networks in 4.1.2 -- I am looking into that. There is always the possibility that we have introduced a bug which is causing normal interfaces to be treated as transient. The only way to catch a device that is doing this, is to select it and type cmd-K, then quickly watch to see if it causes a new network oval to be created. InterMapper doesn't log when new links are created/destroyed; this will be addressed in a future version.
