Question

无法用于外部设备的MIB。

我有一个IP电源条，可以使用SNMP进行控制。我正在尝试使用Python脚本关闭和打开电源。我在d：\ mib中保存了新的mib 我试图将OID设置为0。我正在调用setCmd函数，如下所示

errorIndication, errorStatus, errorIndex, varBinds = next(setCmd(SnmpEngine(),CommunityData('write_public'),UdpTransportTarget(('xx.xx.xx.xx', 161)),ContextData(),ObjectType(ObjectIdentity('1.3.6.1.4.1.13742.6.4.1.2.1.2.1.3',0).addAsn1MibSource('d:/mib'))))

我遇到错误追溯（最近一次通话）：

    errorIndication, errorStatus, errorIndex, varBinds = next(setCmd(SnmpEngine(),CommunityData('write_public'),UdpTransportTarget(('xx.xxx.xx.x', 161)),ContextData(),ObjectType(ObjectIdentity('SNMPv2-MIB','1.3.6.1.4.1.13742.6.4.1.2.1.2.1.3',0).addAsn1MibSource('d:/mib'))))

首先，只要您使用裸OID和值（这就是您要做的），就不需要SNMP的MIB 。

如果要将OID设置为值 0 ，则以下受管对象规范应生成您可能需要的SNMP SET PDU：

ObjectType(ObjectIdentity('1.3.6.1.4.1.13742.6.4.1.2.1.2.1.3'), 0)

如果要使用MIB，则应使用addAsn1MibSource方法，但应将其传递给valid URL。

如何在pysnmp中添加新的MIB文本文件？
