Discovery problems
« on: July 29, 2009, 06:57:59 PM »
Iīve a network with 44 cisco routers, Iīve added the core router to the seedlist and after running nedi.pl and nedi.pl -po and nedi.pl -A, it has just discovery 21 routers.
   I am focusing on finding out why a router that is direct connected to the core doesīt get discovered. It answers SNMP requestes fine. If a do a nedi.pl -a <ip> is works.
   Any ideas on what I could do?

   Tks a lot.

Check that CDP is enabled and that you have DEF files for your router/switch models.

Yes, CDP is enabled and the defs exists. If I do a manual discoevery via nedi.pl, it will detect the router.

Do a -vt (ip of the neighbor) and check whether the router in question shows up....

try adding a -I, nedi may be trying to use interfaces it can't get to in order to get to the devices.

Use -vt in order to get lines starting with CDP:

After adding this router to the seedlist and one other router, Nedi discovered all the network. The only strange thing is why it didīt find it. This router is a 3620. Tks.

The seedlist is only there for you to manualy define devices , Nedi should automatically discover network devices without seedlist.
