snmpwalk works but cacti doesnt

[miller32]

The following command works on the server Cacti is installed on to a test switch:

snmpwalk -v 3 -u miller32 -A heymister -x DES -X 11111111 -l AuthPriv 192.168.2.222 sysUpTime

But I enter the same information into the device section and I recieve the generic SNMP error.

Sidenote: Cacti will work with SNMPv3 + authentication but when I enable encryption on the switch and enter the encryption password into the device page I still recieve the error.

We had issues with SNMP V3. So please provide us with the Cacti version used. And tell us, whether you're using php-snmp or ucd/net-snmp
