Nagios doesn't do network discovery... You'll have to use something else
for that, then export that data and build your nagios configs off of it
somehow.  We're running nagios in a production environment with no issues.
You tell it what to monitor and what type of things to do to your devices,
so in essence, you have complete control over what nagios will do.  We're
dumping CiscoWorks RME database *cringe* since it does a fairly decent job
of network discovery... importing that data into mysql, then generating
nagios configs from mysql.

I don't think nagios can deal with traps..

Why not setup a ucd-snmp's snmptrapd and have it listen for your traps and
perform actions based on certain criteria.   You can set it up to perform
actions (fire off email, etc) depending on the mib recieved.
