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 the 1.3.6.1.2.1.1.1.0 OID (e.g. 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.v1arch.asyncio import *
async def run():
snmpDispatcher = SnmpDispatcher()
iterator = await getCmd(
snmpDispatcher,
CommunityData("public", mpModel=0),
await UdpTransportTarget.create(("demo.pysnmp.com", 161)),
("1.3.6.1.2.1.1.1.0", None),
)
errorIndication, errorStatus, errorIndex, varBinds = iterator
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]))
snmpDispatcher.transportDispatcher.closeDispatcher()
asyncio.run(run())

Bulk walk MIB#
Send a series of SNMP GETBULK requests using the following options:
with SNMPv2c, community ‘public’
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 -v2c -c public -Cn0 -Cr50
demo.pysnmp.com SNMPv2-MIB::system
import asyncio
from pysnmp.hlapi.v1arch.asyncio import *
async def run(varBinds):
snmpDispatcher = SnmpDispatcher()
while True:
iterator = await bulkCmd(
snmpDispatcher,
CommunityData("public"),
await UdpTransportTarget.create(("demo.pysnmp.com", 161)),
0,
50,
*varBinds
)
errorIndication, errorStatus, errorIndex, varBindTable = iterator
if errorIndication:
print(errorIndication)
break
elif errorStatus:
print(
"{} at {}".format(
errorStatus.prettyPrint(),
errorIndex and varBinds[int(errorIndex) - 1][0] or "?",
)
)
else:
for varBind in varBindTable:
print(" = ".join([x.prettyPrint() for x in varBind]))
varBinds = varBindTable
if isEndOfMib(varBinds):
break
snmpDispatcher.transportDispatcher.closeDispatcher()
asyncio.run(run([ObjectType(ObjectIdentity("SNMPv2-MIB", "sysDescr"))]))
