This is what I have on a 2930F, it probably is the same/similar on 2920 (PVOS/AOS-S):
snmpv3 enable
snmpv3 only
snmpv3 restricted-access
snmpv3 group managerpriv user "airwave" sec-model ver3
snmpv3 user "airwave" auth sha "removed" priv aes "removed"
Note that aes-256 is a 'non standardized' encryption for SNMPv3, there are different incompatible (vendor) versions of aes-256; so that may be a reason that it doesn't work. In that case try aes, which is aes-128 and see if that works.
