No ASR920 here, but that sounds like a bug to me... all platforms I've
laid my hands on so far have exported SNMP ifIndex (and the netflow specs
might even document this as such).

"dpix" sounds like "the internal hardware port index" or such, which, if 
there are strong reasons to make it different from the snmp ifIndex (there
could) should go through a mapping on export...
