Can you use Broadcast/Multicast, or does it have to be unicast packets?
If so, You'll want to develop a custom multi-threaded daemon instead of
the standard Nagios + check_snmp model. The overhead of the forking model
gives flexibility, not performance.

Hi Group

Thanks Bryan for the answer. I'm kind of a newbie. I haven't used snmp
until I installed cacti to monitor some routers which I believed is
awesome.

How can I know when to use multicast/broadcast vs. unicast? Is there
any parameter on the net-snmp package files where I can fix this?

If so, for what I understand, is better to use unicast?

Sorry for so many questions. Hope not disturbing.

Thanks in advanced
