snmpv3 with OpUtils

Hi

I'm currently testing a feature with the network monitoring tool OpUtils which enables you to auto-discover a devices IP subnets using snmp.  I can't get this to work using snmpv3, but it works fine using snmpv2.

My guess is the default 'snmp read view' (as it's not specified) doesn't include the MIBs/OIDs Oputils needs to poll using snmpv3?  If this is the case I haven't been able to find what exactly what view & OID I need to specify to allow this? e.g. snmp-server view oputils <OID> included


Can anyone help throw some light on this?
