Modifying variables¶
Coerce value to SET to MIB spec¶
Send SNMP SET request using the following options:
- with SNMPv2c, community ‘public’
- over IPv4/UDP
- to an Agent at demo.snmplabs.com:161
- with MIB lookup enabled
- setting SNMPv2-MIB::sysName.0 to new value (type taken from MIB)
Functionally similar to:
$ snmpset -v2c -c public demo.snmplabs.com SNMPv2-MIB::sysDescr.0 = “new system name”
from pysnmp.hlapi.v1arch import *
iterator = setCmd(
SnmpDispatcher(),
CommunityData('public'),
UdpTransportTarget(('demo.snmplabs.com', 161)),
ObjectType(ObjectIdentity('SNMPv2-MIB', 'sysORDescr', 1), 'new description'),
lookupMib=True
)
errorIndication, errorStatus, errorIndex, varBinds = next(iterator)
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]))

SET scalars values¶
Send SNMP SET request using the following options:
- with SNMPv1, community ‘public’
- over IPv4/UDP
- to an Agent at demo.snmplabs.com:161
- with MIB lookup enabled
- setting three var-bindings to new values
Please note, that in this example MIB lookup is only used for the second var-bindins. For the rest, value types are inferred from passed objects.
Functionally similar to:
$ snmpset -v1 -c public demo.snmplabs.com 1.3.6.1.2.1.1.9.1.2.1 o 1.3.6.1.4.1.20408.1.1 1.3.6.1.2.1.1.9.1.2.1 = 1.3.6.1.4.1.20408.1.1 1.3.6.1.2.1.1.9.1.3.1 s “new system name”
from pysnmp.hlapi.v1arch import *
iterator = setCmd(
SnmpDispatcher(),
CommunityData('public', mpModel=0),
UdpTransportTarget(('demo.snmplabs.com', 161)),
ObjectType(
ObjectIdentity('SNMPv2-MIB', 'sysORID', 1),
ObjectIdentifier('1.3.6.1.4.1.20408.1.1')
),
ObjectType(
ObjectIdentity('1.3.6.1.2.1.1.9.1.2.1'),
'1.3.6.1.4.1.20408.1.1'
),
ObjectType(
ObjectIdentity('1.3.6.1.2.1.1.9.1.3.1'),
OctetString('new system name')
),
lookupMib=True
)
errorIndication, errorStatus, errorIndex, varBinds = next(iterator)
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]))
