Problems with discovery
« on: July 29, 2009, 08:04:45 PM »
I cannot even get manual discovery to see anything using nedi.pl -a.  It returns nothing.  Can anyone help with where to start looking?  I have my Cisco router(my default GW) set with the correct community string and server values.

When I try a different device(an ASA) I get "No name, not discoverable"

It has an entry in the DNS and the GUI resolves it when I do a lookup.

Thanks
T

Looks like your device doesn't have a DEF file so nedi can't discover it properly.
I wouldn't start discovery with an ASA anyway, better try a router or switch somewhere in the core.

Thanks Rufer but since then I have also tried discovery on my 4510 core switch, a 2811 router and a 3550 switch.  I get the same results.  I think those devices are in the default DEF file(C:\var\NeDi\sysobj folder).  If not, where do I find a DEF file.

Why do you use -a? Check with -h what it does...

???  Is not -a the argument to specify a specific address you want to scan?  That is what -h tells me.  I am fairly good with the options now as I had to learn why the original instructions did not work.  Either way with or without arguments I get no responses from any of my devices when other snmp based utilities work fine.

 Try it while capturing the traffic. Do you see snmp packet going to the right device using the right community and version?
