Question

我试图通过python使用snmpset设置值。

import netsnmp
snmpcfgfile=netsnmp.Varbind(".1.3.6.1.4.1.171.12.1.2.18.1.1.5.3", 
                            "switch.cfg","STRING")
netsnmp.snmpset(snmpcfgfile, Version=2, DestHost="10.0.112.4", Community="public")`

（2秒后我看到一个错误）：TypeError：期望的字符串或Unicode对象，找到NoneType

价值不变。

我做错了什么？我应该如何纠正它？

追踪（请帮助理解其含义）：

您可以尝试遵循this blog post的建议，并以字符串形式分解您的OID并以这种方式编制索引：

snmpcfgfile=netsnmp.Varbind("agentBscSwFile", "0", "switch.cfg", "STRING")

您还应该确保可以使用＆＃34; public＆＃34;来编写OID。社区，通常这个社区在默认出厂设置中默认为只读。

祝你好运，关于net-snmp python绑定的文档充其量只是参差不齐。
