[c-nsp] IP Accounting for IPv6

[Chris Mason]

Hi,

A quick question I am sure, but I can't seem to find any reference on
CCO for IP Accounting for IPv6?
I am looking for the IPv6 equivilent of the following command to
provide aggregated per-prefix statistics that remain on the router:

interface Vlan199
 ip accounting output-packets
!

If this isn't supported does anyone know if there are any plans to
support it in the future (using 15M/15T on ISR platforms)?

Thanks in advance,
Chris
