The snmp translation works after syntax correction in the MIB and using the
command above.

I tried to rewrite this MIB (see below) by means of comparing with other
(standard) MIBs. But I don't know how to design the nested NodesTable. Finally,
there should be one tMergeLayerTable which contains multiple NodesTables
(cntNodes entry in TMergeLayerEntry).

I don't know that, I got it as a part of a project at the university.
Thanks for your assistance,
