如何将自定义 mib 文件加载到 snmpd 代理

Question

我正在 docker 中运行 snmpd（polinux/snmpd:alpine 映像），我想将自定义 mib 文件与我为测试目的准备的不同数据类型的 OID 对象一起使用，并通过 2 个不同的在线 mib 验证器对其进行验证，然后我修复了他们向我指出的所有错误，现在我的文件应该没问题，但我仍然无法通过 snmpwalk 找到我的 oid 或通过 snmptranslate 找到我的模块。 这是我尝试过的：

1. 将

   -m <mib file>

   或/和

   -M <mibs dir>

   参数传递给 snmpd - 不起作用
2. 添加

mibdirs +/etc/snmpd/
mibs +ALL

到 snmpd.conf 文件 - 也不起作用

我错过了什么吗？可能出了什么问题？

Answer 1

这可能不是最好的答案，但它确实有效。

将 MIB 文件放入 /usr/share/snmp/mibs

snmp.conf： mibs +MY-MIB

我从未让 mibdirs 指令发挥作用
