There's no link >symbol to a Node. Understood, but I can still run a discovery against the nodes, and they become entries in the system, with all kinds of nice information (hostname, location, desciption, os/version, etc). Regardless of terminology, I'd want that to happen, and it seems like it should have happened automatically when I discovered the Dell switch they were attached to (even if there's no "link"). Actually, this is good, I think this helps me formulate the actual question I was trying to ask previously: How do I configure netdisco so it discovers the Dell switches and server nodes automatically? There are too many to discover manually, and I don't want to have to maintain a list. > >For the bug, if you can tolerate it for a little time I'd appreciate >you waiting for the next release of Netdisco which has a few fixes in >this area. Hope that's OK. Of course, no problem. I'm just testing different applications right now, trying to find something that will generate a nice network map.

There are too many to discover manually, and I don't want to have to maintain a list.Ah OK, yes: Netdisco uses SNMP to contact all devices (as you've worked out), then uses Neighbor Discovery Protocols to ask the device what neighbor devices are on what ports. These protocols are most commonly CDP (Cisco) or LLDP (the standards-based one).So you might need to enable LLDP on your servers somehow. The switch is probably already running it. You can test by running 'show lldp neighbor' or similar, on the switch. It should be sufficient to run LLDP on the server and then Netdisco will find it via the switch's neighbor table.I hope this helps, regards, oliver.

--- Begin Message ---Dear All, Still now there is no improvement on this issue. Is there any alternative method to manually update ARP table. Regards, T9En ----- Forwarded Message ----- From: Veeramachaneni <t...@yahoo.com> To: "netdisco-users@lists.sourceforge.net" <netdisco-users@lists.sourceforge.net> Sent: Friday, 24 January 2014 3:13 PM Subject: Checkpoint VSX Dear All, I have successfully installed ND-2 in my environment. But , for moving to production I'm facing an issue with ND2 & checkpoint VSX. Checkpoint VSX (virtual firewalls) supports SNMP-V3 and i am able to discover the device with SNMP-v3. To do ArpNip it need to use context number. ND2 is doing ARPNIP to default context only. In the said VSX box i'm having total 9 contexts. How can i do ArpNip to all available context. the default ArpNip is feteching "snmpbulkwalk -v 3 -l authNopriv -u netdisco -A netdisco 192.168.1.1 atPhysAddress" this output. But i require "snmpbulkwalk -n ctxname_vsid4 -v 3 -l authNopriv -u netdisco -A netdisco 192.168.1.1 atPhysAddress" and all contexts. I tried configuring context_prefix in snmp_auth but no use.

--- Begin Message ---Hi Oliver, thanks for quick reply. What about a better integration of external scripts into netdisco for the next version? It give netdisco better control over the complete process. It be should done "easy" I think... a global configuration for the script directory and a script option for each device. Or a global configurable script and for each device an option to use it (with given parameter like type and IP). Or a mix of both...
