Various SNMP versions
SNMPv1
Send SNMP GET request using the following options:
with SNMPv1, community ‘public’
over IPv4/UDP
to an Agent at demo.pysnmp.com:161
for an instance of SNMPv2-MIB::sysDescr.0 MIB object
Based on asyncio I/O framework
Functionally similar to:
$ snmpget -v1 -c public demo.pysnmp.com SNMPv2-MIB::sysDescr.0
import asyncio
from pysnmp.hlapi.asyncio.slim import Slim
from pysnmp.smi.rfc1902 import ObjectIdentity, ObjectType
async def run():
slim = Slim(1)
errorIndication, errorStatus, errorIndex, varBinds = await slim.get(
'public',
'demo.pysnmp.com',
161,
ObjectType(ObjectIdentity("SNMPv2-MIB", "sysDescr", 0)),
)
if errorIndication:
print(errorIndication)
elif errorStatus:
print(
"{} at {}".format(
errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex) - 1][0] or "?",
)
)
else:
for varBind in varBinds:
print(" = ".join([x.prettyPrint() for x in varBind]))
slim.close()
asyncio.run(run())

Bulk walk MIB
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.pysnmp.com:161
for all OIDs past SNMPv2-MIB::system
run till end-of-mib condition is reported by Agent
based on asyncio I/O framework
Functionally similar to:
$ snmpbulkwalk -v3 -lnoAuthNoPriv -u usr-none-none -Cn0 -Cr50
demo.pysnmp.com SNMPv2-MIB::system
import asyncio
from pysnmp.hlapi.asyncio import *
async def run(varBinds):
snmpEngine = SnmpEngine()
while True:
bulk_task = await bulkCmd(
snmpEngine,
UsmUserData('usr-none-none'),
UdpTransportTarget(('demo.pysnmp.com', 161)),
ContextData(),
0,
50,
*varBinds
)
(errorIndication, errorStatus, errorIndex, varBindTable) = await bulk_task
if errorIndication:
print(errorIndication)
break
elif errorStatus:
print(
"{} at {}".format(
errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex) - 1][0] or "?",
)
)
else:
for varBindRow in varBindTable:
for varBind in varBindRow:
print(" = ".join([x.prettyPrint() for x in varBind]))
varBinds = varBindTable[-1]
if isEndOfMib(varBinds):
break
return
asyncio.run(
run([ObjectType(ObjectIdentity("TCP-MIB")), ObjectType(ObjectIdentity("IP-MIB"))])
