Where do I specify SNMP version to use?

I am configuring hobbit for mulitple networks that run different SNMP versions.  One network is SNMP version 1 the other network is SNMP version 2c.   Currently the network running SNMPver1 is working perfectly however I am getting SNMP authentication failures on my Cisco devices that run SNMP ver2c.

Is there a config file that I can manipulate to monitor both networks and not recevie the authentication failures on my cisco switches running SNMP ver2c?
