Hi Dave,
I made the host to network order suggestion, and now it works for Get, GetNext
and BulkGet calls.
However iam facing a issues with Getnext/Bulk/Snmpwalk get calls going to the
next table, the bulk/walk requests are NOT going to next table, it traverses to
the beginning of the same table row.
Attached is the file. I really appreciate any help in this regard as this is a
blocking issue.
Thanks,
Anup

If you want a quick-n-dirty hack to get things working,
you could always tweak the vplexDirectorFETable_entry
(and similar) structure to include *two* fields for the
IP address - one held in host order and one in network
order.
Then use one for the index processing (in the get_first
and get_next routines), and the other in the handler
itself (for the column object).
