+Multiple SNMP communities
++++++++++++++++++++++++++
+
+Respond to SNMP GET/SET/GETNEXT queries with the following options:
+
+* SNMPv1
+* with SNMP community "public" (read access) or "private" (write access)
+* allow access to SNMPv2-MIB objects (1.3.6.1.2.1)
+* over IPv4/UDP, listening at 127.0.0.1:161
+
+Allow read/write access to all objects in the same MIB subtree.
+
+The following Net-SNMP's commands will GET/SET a value at this Agent:
+
+| $ snmpget -v1 -c public 127.0.0.1 SNMPv2-MIB::sysLocation.0
+| $ snmpset -v1 -c private 127.0.0.1 SNMPv2-MIB::sysLocation.0 s "far away"
