Hank,

You should also take into consideration the type of the NPE and its current load, as it may become a bottle neck.

I need PA-GE to C7200-I/O-GE connectivity.  For 1500 bytes, what is the kpps one can expect for PA-GE to C7200-I/O-GE connectivity?  IOS train is
12.4(12) but can be upgraded if we know there is better performance at a later version.

Thanks,
Hank
