tablesnmpwalk on table not working via subagent - need help please

The documentation indicates that the following is obsolete:
table_dataset - Helps you implement a table with automatted storage.
This helper is obsolete. If you are writing a new module, please
consider using the table_dataset2 helper instead.

I have found no information about table_dataset2 helper. Does this
exist?

Can anyone clarify for me which code in net-snmp works for the purpose
of implementing a table.

Thanks,

Joan Landry

Subject: snmpwalk on table not working via subagent - need help please


All,
I sent a question on the snmp walk/get next issue last week. I have not
had any replies. So I am not sure what that implies.
 
Has anyone ever used these functions in a subagent?
netsnmp_create_table_data_set
netsnmp_table_set_add_indexes
netsnmp_table_set_multi_add_default_row
 
etc
 
Does anyone know if these functions work for a table - besides a simple
get/set of an object?
I am having no success with using any of the mib2c generated code for
the purpose of being able to do a get next or a walk on a simple table.
I have tried all the different variations of mib2c using the many
different .conf files. Nothing works for getting a get next or walk of a
table to operate correctly. The details are in the original email that
was sent out and pasted below.
 
Should I be using the old style code such as:
REGISTER_MIB("abc", abc_variables, variable4, variables_oid);
 
Thanks for any help you can give - as I am really stuck.
Joan

I have created the following table subagent code. I am able to walk
objects in the table, but if I walk the entire table starting at the top
of the table I get no data returned.
Also, do the functions below work or should I be using the old style
code:
      REGISTER_MIB("abc", abc_variables, variable4, variables_oid);
 
So far I have spent days trying to get a mib walk to work with a very
simple table, using the many different variations of mib2c and nothing I
have done so far works.
 
Please tell me what I could possibly doing wrong with this setup:
   table_set = netsnmp_create_table_data_set("sysORTable");
    table_set->allow_creation = 0;
 
    netsnmp_table_set_add_indexes(table_set, ASN_INTEGER, 0);
    netsnmp_table_set_multi_add_default_row(table_set,
             COLUMN_SYSORINDEX, ASN_INTEGER, 0, NULL, 0, 
             COLUMN_SYSORID,    ASN_OBJECT_ID, 0, NULL, 0,
             COLUMN_SYSORDESCR, ASN_OCTET_STR, 0, NULL, 0, 
             COLUMN_SYSORUPTIME, ASN_TIMETICKS, 0, NULL, 0, 0);
    table_set->table->store_indexes = 1;
    netsnmp_register_table_data_set(netsnmp_create_handler_registration
                                    ("sysORTable",  NULL,
                                     sysORTable_oid,
                                     OID_LENGTH(sysORTable_oid),
                                     HANDLER_CAN_RONLY), table_set,
NULL);
    row = netsnmp_create_table_data_row();
    sysORIndex = 1;
    netsnmp_table_row_add_index(row, ASN_INTEGER, &sysORIndex,
sizeof(sysORIndex));
    netsnmp_set_row_column(row, COLUMN_SYSORID, ASN_OBJECT_ID,
             (u_char *)sysOidSpec[0].id, sysOidSpec[0].len);
    netsnmp_set_row_column(row, COLUMN_SYSORDESCR, ASN_OCTET_STR,
             sysOidSpec[0].sysOidDesc,
strlen(sysOidSpec[0].sysOidDesc));
    netsnmp_set_row_column(row, COLUMN_SYSORUPTIME, ASN_TIMETICKS,
ptr, sizeof(long));
    netsnmp_table_dataset_add_row(table_set, row);
    sysORIndex = 2;
    row = netsnmp_create_table_data_row();
    netsnmp_table_row_add_index(row, ASN_INTEGER, &sysORIndex,
sizeof(sysORIndex));
    netsnmp_set_row_column(row, COLUMN_SYSORID, ASN_OBJECT_ID,
             (u_char *)sysOidSpec[1].id, sysOidSpec[1].len);
    netsnmp_set_row_column(row, COLUMN_SYSORDESCR, ASN_OCTET_STR,
             sysOidSpec[1].sysOidDesc,
strlen(sysOidSpec[1].sysOidDesc));
    netsnmp_set_row_column(row, COLUMN_SYSORUPTIME, ASN_TIMETICKS,
ptr, sizeof(long));
    netsnmp_table_dataset_add_row(table_set, row);
 
this creates 2 rows - and if I walk sysORDesc I get both rows, if I
start the walk at sysOrEntryTable I get nothing.
 
Any help would be appreciated.
Thanks,
Joan
