It's not really. cisco-nsp would be better, since it's a Cisco-specific 
question.

As Gert has said, there isn't. Can't be done. Impossible.

One other workaround is:

  1. Use a QoS policy map on the interface matching all IPv6 traffic
  2. Enable QoS statistics export

This is a neat trick which we've used successfully. It has limits, and 
requires you enable QoS on the platform which opens a whole bunch more 
things to think about. But it does get you IPv6 traffic per-interface. 
I'm not sure if you can get the counters via SNMP though.
