SNMPv3: master auth and privacy keys¶
Send SNMP GET request using the following options:
with SNMPv3, user ‘usr-md5-des’, MD5 authentication, DES encryption
use master auth and privacy keys instead of pass-phrase
over IPv4/UDP
to an Agent at demo.pysnmp.com:161
for SNMPv2-MIB::sysDescr.0 MIB object instance
Functionally similar to:
import asyncio
from pysnmp.hlapi.v3arch.asyncio import *
async def run_snmp_get():
iterator = await get_cmd(
SnmpEngine(),
UsmUserData(
"usr-md5-des",
authKey=OctetString(hexValue="1dcf59e86553b3afa5d32fd5d61bf0cf"),
privKey=OctetString(hexValue="ec5ab55e93e1d85cb6846d0f23e845e0"),
authKeyType=USM_KEY_TYPE_MASTER,
privKeyType=USM_KEY_TYPE_MASTER,
),
await UdpTransportTarget.create(("demo.pysnmp.com", 161)),
ContextData(),
ObjectType(ObjectIdentity("SNMPv2-MIB", "sysDescr", 0)),
)
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]))
asyncio.run(run_snmp_get())

SNMPv3: localized auth and privacy keys¶
Send SNMP GET request using the following options:
with SNMPv3, user ‘usr-md5-des’, MD5 authentication, DES encryption
use localized auth and privacy keys instead of pass-phrase or master keys
configure authoritative SNMP engine ID (0x0000000000 can be used as well)
over IPv4/UDP
to an Agent at demo.pysnmp.com:161
for SNMPv2-MIB::sysDescr.0 MIB object instance
Functionally similar to:
import asyncio
from pysnmp.hlapi.v3arch.asyncio import *
async def run_snmp_get():
iterator = await get_cmd(
SnmpEngine(),
UsmUserData(
"usr-md5-des",

securityEngineId=OctetString(hexValue="80004fb805636c6f75644dab22cc"),

Concurrent queries¶
Send multiple SNMP GET requests at once using the following options:
with SNMPv2c, community ‘public’
over IPv4/UDP
to multiple Agents at demo.pysnmp.com
for instance of SNMPv2-MIB::sysDescr.0 MIB object
based on asyncio I/O framework
Functionally similar to:
import asyncio
from pysnmp.hlapi.v3arch.asyncio import *
async def getone(snmpEngine, hostname):
errorIndication, errorStatus, errorIndex, varBinds = await get_cmd(
snmpEngine,
CommunityData("public"),
await UdpTransportTarget.create(hostname),
ContextData(),
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]))
async def main():
snmpEngine = SnmpEngine()
await asyncio.gather(
getone(snmpEngine, ("demo.pysnmp.com", 161)),
getone(snmpEngine, ("demo.pysnmp.com", 161)),
getone(snmpEngine, ("demo.pysnmp.com", 161)),
)
asyncio.run(main())

Sequential queries¶
Send multiple SNMP GET requests one by one using the following options:
with SNMPv2c, community ‘public’
over IPv4/UDP
to multiple Agents at demo.pysnmp.com
for instance of SNMPv2-MIB::sysDescr.0 MIB object
based on asyncio I/O framework
