SNMPv1
++++++
Send SNMP GET request using the following options:
* with SNMPv1, community 'public'
* over IPv4/UDP
* to an Agent at demo.pysnmp.com:161
* for an instance of SNMPv2-MIB::sysDescr.0 MIB object
* Based on asyncio I/O framework
Functionally similar to:
| $ snmpgetnext -v1 -c public demo.pysnmp.com SNMPv2-MIB::sysDescr.0
