Which mib2c template are you using?
Many of the table helpers require a particular structure
for the per-row data structure, so that they can compare
an incoming request with the index for each row in the
table, and hence identify which row is required.
Sometimes this index value is hidden within "private"
data structures, and the MIB module implementor will
never see it. For other helpers, the per-row index field
is included within the main per-row data structure.
That sounds like what you've got here.

It's not a question of what happens when an SNMP message arrives,
it's more concerned with what happens when you load the internal
representation of the table.
The 'net-snmp_index' field hold the index value for a given row.
