Thanks for your fast answer. I attach all source files and the whole MIB-file. Please only compile the files indusol.c, network_data.c and module_param.c at the moment. The full implemented module needs all file objects.
How it is possible to reference to other table indexes and the specific OID? You see my implementation within the sources, but i think this is not the regular way to get the index in this way. Maybe this could be the possible error.
