SNMP OID for IPv6 traffic

Hi Gert,

I agree that i can only see control-plane inbound traffic with "show 
interface accounting". I also think that when i would be able to see 
hw-forwarded traffic with this command the problem with SNMP OID would 
be also solved.

I only hope is not some hardware limitation on SUP720 or RSP720.
Maybe someone from CISCO can give us more details.
