"""
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
