Checking the code, it appears that this particular entry is explicitly
omitted from the list of valid MIB objects.   I'll check with the author
of this module as to whether this is deliberate (and why the HC version
is handled differently).

If you want to enable this, then have a look at the file
    agent/mibgroup/ip-mib/ipSystemStatsTable/ipSystemStatsTable_data_access.c
and look for the array 'my_columns'  (around line 61).

The entry for COLUMN_IPSTATSINOCTETS is commented out.
If you uncomment this and re-compile, then this entry should appear
in the snmpwalk output.

One note of warning - enabling this column does not mean that the
agent will automatically return the appropriate value.  If there isn't
any code to retrieve the correct value from the kernel, then the agent
won't give you the right answers.
   My suspicion is that the ipStatsInOctets and ipStatsHCInOctets
objects are probably not implemented, and should *both* be omitted
from the snmpwalk output.   But I'll check with Robert.
