在第一次尝试pysnmp时，我很难加载自定义MIB。我读到旧版本需要编译自定义mib，而新版本则将编译嵌入后端进程中。当我尝试任何一种方法时，脚本都会挂起。。。无限期地自定义MIB是CISCO-PRODUCTS.MIB，我已经下载了它，并以.my扩展名结束。

同一目录中的文件为：
- CISCO-PRODUCTS-MIB.my
- 思科SMI.my
- mibdump.py
- SNMPv2-CONF.my
- SNMPv2-SMI.my
- SNMPv2-TC.my
有人知道错误在哪里吗？
添加--mib-searcher参数可解决问题`
mibdump.py --disable-fuzzy-source --mib-source /home/user/.snmp/mibs --mib-searcher=/home/user/.snmp/mibs --destination-format pysnmp [MIB_ MODULE]
其中[MIB_MODULE].MIB文件出现在/home/user/.snmp/mibs目录中
