I have a small Python program that sets the SNMP V2 zSnmpCommunity property. It would be trivial to modify that to change the SNMP V3 properties:

#!/usr/bin/env python
#
# Author: Jane Curry
# Date October 30th 2012
# Description: Sets local zSnmpCommunity property to new value
# Updates:
#
import sys
import Globals
import time
from Products.ZenUtils.ZenScriptBase import ZenScriptBase
from transaction import commit

#of = open('/home/zenoss/zSnmpCommunityChange.out', 'w')
of = open('/z/zSnmpCommunityChange.out', 'w')
localtime = time.asctime( time.localtime(time.time()) )
of.write(localtime + "\n\n")
# Need noopts=True or it barfs with the script options
dmd = ZenScriptBase(connect=True, noopts=True).dmd

zSnmpCom = 'newCommunity'
for dev in dmd.Devices.getSubDevices():
# Test for devices in a particular IP range
#if dev.manageIp.startswith('10.73'):
# Test for a specific device - for testing
if dev.id == 'zenny1.class.example.org':

# do NOT use the following line ( dev.zSnmpCommunity = zSnmpCom ) to set a local property
# as it bypasses the aquisition chain and you end up with "half" a local property such
# that Configuration Properyties does not see the change, the deleteZenProperty method
# cannot find the property but the new community IS used by SNMP methods - Disaster!
#dev.zSnmpCommunity = zSnmpCom
dev.setZenProperty('zSnmpCommunity', zSnmpCom )
of.write('Device %s has zSnmpCommunity local property set to %s \n' % (dev.id, dev.zSnmpCommunity))
print 'Device %s has zSnmpCommunity local property set to %s \n' % (dev.id, dev.zSnmpCommunity)
commit()
of.close()

Subject:	As-is, the script above

As-is, the script above cycles through all devices known to Zenoss but only changes the one that matches id of 'zenny1.class.example.org'; there is also a commented-out line that would include devices in a certain IP address range.

To run this in Zenoss 5, I have my environment set up as per http://zenpacklib.zenoss.com/en/latest/development-environment-5.html . My script is in /z/setSnmpCommunity.py , owned and executable by user zenoss. You need to run it in the zope container - with the above referenced environment, you simply type:

zope

cd /z

./setSnmpCommunity.py

You get output printed to the screen and to an output file (also under /z).

Cheers,

Jane
