The first thing that strikes me about that MIB file is that you are
defining a table with no accessible content.
The oamIndex column is defined as being "not-accessible"
(which is correct), but the two "column1/2" objects are also
defined as "not-accessible".
This means that there is nothing in this table which can
be retrieved via SNMP.

I'm not convinced that this code is the output of mib2c.
Given that all three MIB objects are not-accessible,
then I'd expect the default row call to be empty.
The OID given in 'oamTable_oid' doesn't match the OID from the
MIB file either.

If you are using the 'table_dataset' helper, then you don't need
a handler routine. The dataset handler will deal with this for you.

What is the exact GET request(s) that you are trying?

Again, I don't believe that this was generated by mib2c.

That would be correct, yes.

That is how things should work, yes.
Apart from the problems mentioned above (like not having any valid
columns in your MIB!)

That is a very old release, and the 5.1.x line is no longer supported.
You might wish to upgrade to a more recent version (e.g. 5.4.1).
Though the problems you have outlined are probably not version
specific.
