SNMPv3: auth SHA, privacy AES128
++++++++++++++++++++++++++++++++
Send SNMP GET request using the following options:
* with SNMPv3, user 'usr-sha-aes', SHA authentication, AES128 encryption
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* for SNMPv2-MIB::sysDescr.0 MIB object
Available authentication protocols:
#. usmHMACMD5AuthProtocol
#. usmHMACSHAAuthProtocol
#. usmNoAuthProtocol
Available privacy protocols:
#. usmDESPrivProtocol
#. usm3DESEDEPrivProtocol
#. usmAesCfb128Protocol
#. usmAesCfb192Protocol
#. usmAesCfb256Protocol
#. usmNoPrivProtocol
Functionally similar to:
| $ snmpget -v3 -l authPriv -u usr-sha-aes -A authkey1 -X privkey1 \
| -a SHA -x AES \
| demo.snmplabs.com \
| SNMPv2-MIB::sysDescr.0
