Let me share a couple of things I did wrong in netdisco1's SNMPv3 support:

• Fallback to SNMPv2/SNMPv1

  Once we try all the SNMPv3 users we know, we don't fall back to SNMPv2/SNMPv1. This makes it pretty hard to manage a mixed network. I wrote the support on a network that was homogeneous and was easy to support SNMPv3 everywhere, but I am currently running netdisco on a heterogeneous network and it is a real pain.

• Assuming that a given username always has the same credentials

  I was trying to simplify things, by storing only the username in the database and leaving the credentials themselves in the config file - however, it turns out that in real networks things aren't always as clean as in my mind. It'd be nice to allow for different devices having the same user but different auth levels.

• Auth/Enc levels

  My representation of authPriv vs. authNoPriv seems to confuse everyone who tries to use it. I confabulated read-only vs. read-write with auth / encryption. I don't have a concrete suggestion here other than to separate out the ro/rw credentials just like we do with communities
