[c-nsp] asr9k (xr 4.1.2) null 0 traffic not showing packets in packets out

[Aaron]

I have a static route pointing to null 0. I know I have traffic flowing
towards null 0, but "sh int null 0" shows no packets out.  Why not ?

 

I have 7609's that I point static routes to at null 0 and I see packets out,
and I get to mrtg traffic graph that blackholed traffic.  But I don't seem
to see the same thing in asr9k.  is there a way to see that traffic that is
going out null 0 on my asr9k ?
