Remo,
Thank you for responding.
switch2 is the seed device which I based the discovery on. switch32 is just an example of one of the immediate neighbors of switch2. I think the strange icon is a result of the device not getting a "full" discovery (i.e. CDP only of the neighbor, SNMP is not performed - see detail below).
The general discovery (e.g. nedi.pl -p or simply nedi.pl), using the seedlist, picks up switch32 along with all the other devices directly attached (CDP neighbors) to switch2. However the discovery stops there. In the example, switch32 is discovered but is not interrogated for neighbors of its own (in spite of having many).
If I add the immediate neighbors (e.g. switch32) of the seed to the seedlist, the general discovery then picks up the second-level neighbors, but then stops at the at that level of depth (i.e. only discovers or re-discovers direct neighbors of the seed(s) and does not pick up any subordinate neighbors).
The other thing I’ve noticed is that when an immediate neighbor is discovered (on a general discovery using the seedlist) it gets listed as Mode: Not SNMP next to the VTP domain name under the group field. (see attached)
However if I delete the device from the DB/NeDi & perform a manual discovery of the device (e.g. nedi.pl -a device_name/IPaddr) it fully discovers the switch (including snmp) & performs a CDP discovery of its neighbors (but alas no snmp).
So to answer your specific question "is it switch2 or 32 causing the problem?", it is neither (or both). If I do a global discover (nedi.pl -p or nedi.pl or nedi.pl -rp, etc.) using a seedlist w/ the most visible node on my network or a seedlist with many nodes, I never get past a single level (from the seed) of discovery, and the discovery does not pick up SNMP values (or appear to try, since a host discovery does) for any device other than the seed itself. Is there a diagnostic I can run that goes beyond the standard logs (which appear to be of little value here)?
Hope this helps clarify the situation.

PS I've included a drwg & a couple of screen shots to hopefully give a clearer picture.
discovery_problem => an example view of the discovery landscape
switch31_genDisc => the record of a neighbor after a general (seedlist) discovery
switch31_sprecificDisc => record of same neighbor after a delete & specific device discovery (nedi.pl -a device)
