There are two things I have seen happen. 1. Sometimes a switch port is labeled with a Subnet list (usually ifIndex 1). The L2 engine does not automatically change network labels to the port number - you can do this manually. 2. It is possible for devices to exist on your map that L2 cannot locate. When this happens, the connection logic defaults to layer 3. In the Status window for an interface, look for the "Interface Connection" section. If this section exists, it will provide the L2 data used to locate the device. jlixfeld wrote: > > 2.

Open the Interfaces window for a device and check the box next to the appropriate interface to make it visible again. In 5.4.5, we are adding a "Show Adjacent" command available using a specific keystroke. This will make it easier in certain cases to correct maps for hidden connections. jlixfeld wrote: > > 3.

If not, it sounds like you have "Limited" mode enabled. Please open the Server Settings window and check which radio button is selected. If the "Limit Layer 2 Discovery to CDP and LLDP" is checked, then you are in limited mode. jlixfeld wrote: > > In the Connections pane, it only shows two connections (that is, two device > names with "*" to the left of them).

If you can confirm that you are running in Limited mode, Support can send you a new "switches.zip" file for you to install. -------------------- m2f -------------------- Read this topic online here: http://forums.dartware.com/viewtopic.php?p=3519#3519 ____________________________________________________________________ List archives: http://www.mail-archive.com/intermapper-talk%40list.dartware.com/ To unsubscribe: send email to: [email protected]
