NeophyteI don't think that SNMPv3 is really worth it in the private enterprise where everything is already hidden behind firewalls and RFC1918 networks. The data being gathered really isn't all that sensitive.
DMZ? Yeah, that's a place for it just in case but in the private network area I think SNMPv3 is overkill.
Just my opinion. Last gig I was at I worked hard removing SNMPv3 from all of the private stuff with 98% of the issue being with getting the other engineers to understand the lack of privacy issues involved with private networking.
I have a juniper stack in my lab (3xEX4200) that I am hitting regularly with SNMPv2 without hiccup or problem. Perhaps move away from SNMPv3 where you do not need it?
