+# Send SNMP GET request using the following options:
+#
+# * with SNMPv3, user 'usr-md5-none', securityName 'myuser'
+# MD5 authentication, no privacy
+# * over IPv4/UDP
+# * to an Agent at demo.snmplabs.com:161
+# * for an OID in text form
+#
+# The securityName parameter can be thought as an alias to userName and
+# allows you to address a USM Table row just as userName does. However
+# securityName can be made human-readable, also it is not an index in
+# usmUserTable, thus duplicate securityName parameters are possible.
