Preload PySNMP MIBs
+++++++++++++++++++
Send a series of SNMP GETNEXT requests using the following options:
* with SNMPv3 with user 'usr-md5-des', MD5 auth and DES privacy protocols
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* for all OIDs starting from 1.3.6
* preload all Python MIB modules found in search path
Functionally similar to:
| $ snmpwalk -v3 -l authPriv -u usr-md5-des -A authkey1 -X privkey1 -m ALL demo.snmplabs.com:161 1.3.6
"""#
from pysnmp.hlapi import *
