#
# Command Generator
#
# 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.
