PySNMP添加自定义MIB
PySNMP添加自定义MIB
提问于 2018-08-22 05:21:32
我一直在尝试让自定义MIB工作，但没有成功。
理想情况下，我希望从ASN1源中获得MIB的完整列表，但由于失败，我尝试了多种选择。
我已经下载了IF-MIB和IANAifType-MIB，并复制了基于文本和PySNMP格式的编译版本，但似乎都没有读到。未编译.py文件。

/usr/local/lib/python3.5/dist-packages/pysnmp/smi/mibs/__pycache__/INET-ADDRESS-MIB.cpython-35.pyc我尝试使用以下内容从snmplabs站点导入：
from pysnmp.smi import builder
# load mibs
MIBDIR = 'http://mibs.snmplabs.com/asn1/@mib@'
mibBuilder = builder.MibBuilder()
mibSources = mibBuilder.getMibSources() + (builder.DirMibSource(MIBDIR),)
mibBuilder.setMibSources(*mibSources)我还尝试将.addAsn1MibSource('http://mibs.snmplabs.com/asn1/@mib@')附加到cmdgen上我的OID的末尾。
我仍然得到像SNMPv2-SMI::mib-2.2.2.1.2.27 = Ethernet0/1/0.101这样的输出，而不是IF-MIB::ifDescr.27 = STRING: Ethernet0/1/0.101。我还能做些什么来找出我做错了什么？

对不起，由于没有足够的声誉，无法回复评论................你能为上面的答案提供一个例子吗？我终于明白了
pysnmp.smi.error.SmiError: ObjectType object not fully initialized
为
ObjectType(ObjectIdentity('1.3.6.1.2.1.25.2.3').loadMibs('HOST-RESOURCES-MIB'))
到目前为止，我遵循的步骤是
from pysnmp.hlapi import ObjectIdentity, ObjectType
mibBuilder = builder.MibBuilder()
mibBuilder.addMibSources(builder.DirMibSource('C://Users//Downloads//HOST-RESOURCES-MIB.txt'))
errorIndication, errorStatus, errorIndex, \
varBindTable = cmdgen.CommandGenerator().bulkCmd(
cmdgen.CommunityData('test'),
cmdgen.UdpTransportTarget(('test-ip', 161)),
0,
1,
ObjectType(ObjectIdentity('1.3.6.1.2.1.25.2.3').loadMibs('HOST-RESOURCES-MIB'))
)
if errorIndication:
print(errorIndication)
else:
if errorStatus:
print('%s at %s\n' % (
errorStatus.prettyPrint(),
errorIndex and varBindTable[-1][int(errorIndex)-1] or '?'
))
else:
for varBindTableRow in varBindTable:
for name, val in varBindTableRow:
print('%s = %s' % (name.prettyPrint(), val.prettyPrint()))页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
