Python：网络交换机SNMP

示例（一）

# more snmp1.py 
#!/usr/bin/python3.4
# -*- coding=utf-8 -*-

from pysnmp.hlapi import *

#varBinds是列表，列表中的每个元素的类型是ObjectType（该类型的对象表示MIB variable）
errorIndication, errorStatus, errorindex, varBinds = next(
    getCmd(SnmpEngine(),
          CommunityData('CommunityString'),
          UdpTransportTarget(('交换机IP地址',161)),
          ContextData(),
          ObjectType(ObjectIdentity('1.3.6.1.2.1.1.1.0')),
          ObjectType(ObjectIdentity('1.3.6.1.2.1.1.2.0')))
)

if errorIndication:
    print(errorIndication)
elif errorStatus:
    print('%s at %s' % (
            errorStatus.prettyPrint(),
            errorindex and varBinds[int(errorindex)-1][0] or '?'
        )
    )

for varBind in varBinds:
    print(varBind)

执行结果：
