Errr... no.

ifTable.1.1 is ifIndex,   so GETNEXT on ifTable.1.1 would return the value
of ifIndex.{first} (being the first accessible instance within the table).
Similarly,  GETNEXT  on ifTable.1 would also return   ifIndex.{first}

In order to get an entry from the second row of the table (and assuming
that the first value of ifIndex was 1), you would need to run GETNEXT
on  ifTable.1.1.1 = ifIndex.1

More generally, if GETNEXT ifTable.1 (or GETNEXT ifTable.1.1)
returned a value of {N},  then the second index would be retrieved
by running  GETNEXT on ifTable.1.1.{N}

The simplest way to retrieve the table is to use 'snmptable'
or 'snmpwalk' - sure.
