+SNMPv2c
++++++++
+
+Send SNMP GET request using the following options:
+
+  * with SNMPv2c, community 'public'
+  * over IPv4/UDP with non-default timeout and no retries
+  * to an Agent at demo.snmplabs.com:161
+  * for two instances of SNMPv2-MIB::sysDescr.0 MIB object,
+  * based on Twisted I/O framework
+
+Functionally similar to:
+
+| $ snmpget -v2c -c public -r 0 -t 2 demo.snmplabs.com SNMPv2-MIB::sysDescr.0
