+Send SNMP GET request using the following options:
+
+* with SNMPv3 with user 'usr-md5-des', MD5 auth and DES privacy protocols
+* use remote SNMP Engine ID 0x80004fb805636c6f75644dab22cc (USM
+  autodiscovery will run)
+* over IPv4/UDP
+* to an Agent at demo.snmplabs.com:161
+* setting SNMPv2-MIB::sysName.0 to new value (type coerced from MIB)
+
+Functionally similar to:
+
+| $ snmpset -v3 -u usr-md5-des -l authPriv -A authkey1 -X privkey1 \
+|       -E 80004fb805636c6f75644dab22cc demo.snmplabs.com \
+|       SNMPv2-MIB::sysORDescr.1 = "new system name"
