Hi Gandalf, I am using SNMP Auth Protocol and SNMP Privacy Protocol.
However, I am not using SNMP Context - do I need to do something special
here?

When you want to run "AuthNoPriv", then please do both
- do NOT use a privacy passphrase
- set privacy protocol to "NONE"
the last is required!
Starting with 087h, we will set AuthNoPriv automatically in case a
passphrase is 
missing. Until then, you must set NONE
