[c-nsp] Rate limiting problem under 12.0(27) S1

[Rodney Dunn]

Can you do:

clear count

wait 30 seconds:

sh int Serial4/0/0/22:0 stat

wait 30 seconds:

sh int Serial4/0/0/22:0 stat

I want to understand if you are dCEF switching
all the traffic going in/out this interface.

Did you confirm on the downstream router it's indeed
not being rate limited?

What we suggest is that if you are trying to do rate-limiting
on an interface you do it with MQC:

policy-map test
class class-default
  police <blah>

and then attach the service-policy in or out.
