PYSNMP 4.4.12-无法编译自定义 MIB

Question

在我第一次尝试 pysnmp 时，我正在努力加载自定义 MIB。我读过旧版本需要编译自定义 mib，而新版本将编译嵌入到后端进程中。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，我已下载并以 .my 扩展名结尾。

python3 mibdump.py  --mib-source=file://./ --destination-directory=/home/myuser/Desktop/Ansible/mibs --destination-format=pysnmp  CISCO-PRODUCTS-MIB

Source MIB repositories: file://./  Borrow missing/failed MIBs from:
http://mibs.snmplabs.com/pysnmp/notexts/@mib@  
Existing/compiled MIB locations: pysnmp.smi.mibs, pysnmp_mibs

Destination format: pysnmp  
Parser grammar cache directory: not used  
Also compile all relevant MIBs: yes  
Rebuild MIBs regardless of age: no

同一目录下的文件有：

• CISCO-PRODUCTS-MIB.my
• CISCO-SMI.my
• mibdump.py
• SNMPv2-CONF.my
• SNMPv2-SMI.my
• SNMPv2-TC.my

有谁知道错误在哪里？

添加--mib-searcher 参数可以解决问题`

mibdump.py --disable-fuzzy-source --mib-source /home/user/.snmp/mibs --mib-searcher=/home/user/.snmp/mibs --destination-format pysnmp [MIB_ MODULE]

[MIB_MODULE].mib 文件在 /home/user/.snmp/mibs 目录中的位置
