Template:FAQ:MIBs 05

This is similar to the previous questions. In this case, it's stating that it can't find the specified module - either because it's not installed properly, or the name used is subtly wrong.

If it's just one or two modules that are not being found, check that the files are in the expected location, are readable, and the name being used is correct. Note that the name reported is the name of the MIB module, which is not necessarily the same as the name of the file. See the question 'How do I add a MIB to the tools?' for more details on this.

If the tool is generating a whole slew of errors, then it's likely that either the MIB files haven't been installed at all, or the library is looking in the wrong place. See the previous two questions.
