Hello everybody,
does anybody have an idea, why one switch from my switches has no nodes in the node-list?
It is stack of 4 pcs Cisco C9300L-48T-4X. From other Stacks, mainly of WS-C2960X-48TD-L
i see the nodes list entrys perfect ?
How does nedi find and store nodes information in the database ?
thanx in advance,
Josef

Hi
Maybe your Nedi doesn't have a definition file for that switch stack and is unable to pull all data the switch has to offer.
If you try to re-discover the stack from via web GUI by hitting the radar icon in SNMP line or the command line with "nedi.pl -v -SGg -a ip-address-here", does Nedi print right in the beginning something like "SOBJ:Reading 1.3.6.1.4.1.11.2.3.7.11.140.def (HP2530-24G)"? The SysObjId and Type would be something else in your case.
If definition file is missing, you could try following Remo's guide on definition file creating: http://www.nedi.ch/documentation/expand/

With a verbose discovery you don't see any FWDS lines? They'd indicate reading MACs. Alternatively you can provide CLI access to NeDi and you should see FWDC lines.
It's actually a good topic for the next tutorial, I'll hopefully be able to provide soon...
-
Hi Remo,
yes, indeed there are no FWDS lines, i think the problem could be here:
Output from verbose discorvery:
Prepare (CLI) ---------------------------------------------------------------- Wed Oct 7 10:50:14 2020
PREP:IF-addr unsupported
DISC:Clistatus = unsupported mode ifa
__________
This output is just one section before the "Bridge Forward (CLI)" including the FWDC lines (on all the other Switches)
regards,
Josef

No, that's just a misleading debuginfo (I'm going to remove it again).
Check the "MAC Address" setting in Defed. You can email me for assistance...
-
Thanx Remo,
Problem solved - It was a missing entry of the "MAC Address" field in Defed. I set the value to "Vlan community Index", like in all other Cisco Switches -> now I can see all the nodes connected to this switch in the Nodelist.
-> Close case & open a beer
regards,
Josef
