Not always.  Just do:

sho ip cache flow | incl Null
to see pkts that are null routed and that are not counted via the null0 interface.

show interface null0 always works on Cisco boxes. You can see in/out
packets as well.

Did you try looking at "show interface null0"?
I am not sure it works, but give it a try as I do not have quick access
to a lab where I can test this.

Subject: [c-nsp] Counters for null0?

Hi, is there any way to see how much traffic is going to null0
interface?
I configured several routes to be forwarded to null0 and I would like to
have some info about how much traffic is going there.
If the IOS doesn't provide any information about it... is it possible to
obtain that information using netflow?
