I have a map that started off displaying layer 3 connections. I then installed and enabled IMDC and went through all the steps to enable Layer 2 in Maps Settings and Server Settings. One I was done, I clicked "Change Now" in Map Settings and forced a layer 2 data collection in the Server settings.
Once those steps were completed, I saw drastic changes to the maps as anticipated, but I'm not sure if what I saw was totally expected of if there is still some incompleteness going on: 1. While many networks and connections were removed, for devices that had adjacent devices connected, it still showed the network bubble that connected the devices together at layer 3 previously. I'm not sure if this is expected behaviour or not, as I would almost expect all the layer 3 info to be deleted and just have connections displayed between devices without the layer 3 bubble. 2. I deleted some networks and connections from some devices that were discovered after I added a new network and rescanned it, but I realized afterwards that these connections should have been preserved, but re-scanning the network doesn't seem to bring back those connections. Is there a way I can have those networks and connections re-discovered or do I have to delete the device first and then re-discover the device or network? 3. I'm confused by the Layer 2 window. It shows 40 devices, which is the same number of devices I have in the map. Each device in the Device Filter pane seems to show all of the proper connections, but there is nothing displayed in the Endpoints pane when I check on a device in the Device Filter pane. In the Connections pane, it only shows two connections (that is, two device names with "*" to the left of them). The rest of the entries in the Connections pane indicate that they are connected to a switch that is actually network, not a switch (see above where I say that my map still displays networks after the conversion to Layer 2). I have CDP enabled on every one of my devices and I've verified that CDP discovery is working properly by querying a bunch of device's CDP tables manually. SNMP is working because the device is displayed on the map. I don't run spanning tree and I don't use VLANs. Essentially my network is entirely layer 3, but there is still a layer 2 c! onnection between adjacent devices so there is still a MAC address/ARP entry on the device for it's neighbor. I would thusly expect Layer 2 to work as expected, but I'm not sure if my expectations differ from how the implementation actually works. Anyone have any insight? -------------------- m2f -------------------- Read this topic online here: http://forums.dartware.com/viewtopic.php?p=3514#3514 ____________________________________________________________________ List archives: http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ To unsubscribe: send email to: [email protected]
