什么是IFMIB：snimpy.mib.smi异常：找不到b'IFMIB'（检查路径）？

Question

我遵循the doc，但出现以下错误：

>>> from snimpy.manager import Manager as M
from snimpy.manager import load

load("IF-MIB")
m = M("localhost")
print(m.ifDescr[0])
Traceback (most recent call last):
  File "<input>", line 4, in <module>
  File "/home/ed8/projects/coaxis-opt/env/lib/python3.5/site-packages/snimpy/manager.py", line 578, in load
    m = mib.load(mibname)
  File "/home/ed8/projects/coaxis-opt/env/lib/python3.5/site-packages/snimpy/mib.py", line 605, in load
    raise SMIException("unable to find {0} (check the path)".format(mib))
snimpy.mib.SMIException: unable to find b'IF-MIB' (check the path)

问题

什么是IF-MIB？我需要在我的系统上安装一些软件包吗？你知道吗
