Switching from SNMPv2 to SNMPv3

[cwscribner]

Hi all.

The majority of the network devices Nagios is currently monitoring is done over SNMPv2. My client is reconfiguring CiscoWorks to communicate with these devices over SNMPv3. Are there any big hurdles to switch Nagios from using SNMPv2 to SNMPv3? Do I need to install anything to make this happen or can I just change what commands are used to do the monitoring?

I will talk to our SNMP guy to find out if there are any possible issues with using SNMPv3 in Nagios. You can probably modify one of your checks for v3 and test it to see if it is going to work. I hope this link can get you started:
