How to pass MIB to the Manager¶
- How to make use of random MIBs at my Manager application?
Starting from PySNMP 4.3.x, plain-text (ASN.1) MIBs can be automatically parsed into PySNMP form by the PySMI tool. PySNMP will call PySMI automatically, parsed PySNMP MIB will be cached in $HOME/.pysnmp/mibs/ (default location).
MIB compiler could be configured to search for plain-text MIBs at multiple local and remote locations. As for remote MIB repos, you are welcome to use our collection of ASN.1 MIB files at http://mibs.snmplabs.com/asn1/ as shown below.
from pysnmp.hlapi import *
errorIndication, errorStatus, errorIndex, varBinds = next(
getCmd(SnmpEngine(),
CommunityData('public'),
UdpTransportTarget(('demo.snmplabs.com', 161)),
ContextData(),
ObjectType(ObjectIdentity('IF-MIB', 'ifInOctets', 1).addAsn1MibSource('file:///usr/share/snmp', 'http://mibs.snmplabs.com/asn1/@mib@')))
)
if errorIndication:
print(errorIndication)
elif errorStatus:
print('%s at %s' % (
errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex)-1][0] or '?'
)
)
else:
for varBind in varBinds:
print(' = '.join([ x.prettyPrint() for x in varBind ]))

Alternatively, you can invoke the mibdump.py (shipped with PySMI) by hand and this way compile plain-text MIB into PySNMP format.
