+Custom PySNMP MIBs location
++++++++++++++++++++++++++++
+
+Send a series of SNMP GETBULK requests using the following options:
+
+* with SNMPv3, user 'usr-none-none', no authentication, no privacy
+* over IPv4/UDP
+* to an Agent at demo.snmplabs.com:161
+* for all OIDs within TCP-MIB::tcpConnTable column
+* TCP-MIB Python module will be searched by a user-specified filesystem
+ path (/opt/mib/pysnmp) and in Python package (python_packaged_mibs)
+ which should be in sys.path
+
+Functionally similar to:
+
+| $ snmpbulkwalk -v3 -lnoAuthNoPriv -u usr-none-none -Cn0 -Cr50 \
+| demo.snmplabs.com TCP-MIB::tcpConnTable
