+SNMPv3, auth: SHA, privacy: AES128
+++++++++++++++++++++++++++++++++++
+
+Send a SNMP GET request
+* with SNMPv3 with user 'usr-sha-aes', SHA auth and AES128 privacy protocols
+* over IPv4/UDP
+* to an Agent at 195.218.195.228:161
+* for an OID in tuple form
+
+This script performs similar to the following Net-SNMP command:
+
+| $ snmpget -v3 -l authPriv -u usr-sha-aes -a SHA -A authkey1 -x AES -X privkey1 -ObentU 195.218.195.228:161  1.3.6.1.2.1.1.1.0
