Thanks Wes. Ignore my last query on netsnmp_table_helper_add_indexes().
I found where I did make the mistake.

Tree structures are not supported by SMIv2 (the MIB language). If
you're getting the point of needing to do that it's probably time to
pick up a book on good mib design ("Understanding SNMP MIBs" is a good one).

If you're familiar with relational databases, MIBs follow similar
concepts. The topic is much longer than I can explain quickly over
mail, so I suggest you either read a good book or read the RFC itself
(RFC2578).
sp> I have added all the columns.
sp> netsnmp_table_helper_add_indexes(table_info,
The only columns you should add are the indexes. The rest of them
shouldn't be there.
But how to tell about the columns? I do update the values of
table_info->min_column =;
table_info->max_column = ;
stack trace of crash point. This is for a single table.

netsnmp_table_helper_add_indexes(table_info, ASN_INTEGER,
/* ASN_OCTET_STR,
ASN_INTEGER,
ASN_INTEGER,
ASN_INTEGER,*/ 0);
It works fine if I uncomment the commented part from the above . any missing
piece? attaching the file for your reference
