SNMPV3

[py]

the most recent version of PySNMP (like 4.1.x) has SNMP v3 support.
(not sure if its 100% or not...check with developer).

Anyhow I think the documentation explains how to use PySNMP
(http://pysnmp.sourceforge.net/docs/4.1.x/index.html) ....i think the
"interface" is common amongst the different SNMP versions that are
supported by PySNMP.  So i think if you use the
CommandGenerator.nextCmd method...its the same format for snmp v2 and
v3, etc.

It took me a little bit to grasp the API but once I did it works well
(although I am not using SNMP v3)
